BACKGROUND OF THE INVENTION The present invention relates to a sun-winged superstructure consisting of a roof element, sidewalls, front wall, rear wall and floor to maintain the cargo at a suitable temperature and to supply fresh air, consisting of two spaces, a cargo space and a preparation space. Between the two spaces, an air flow limiting means is provided between the two spaces and, where appropriate, mechanical equipment for generating an appropriate air temperature in the preparation space, comprising at least the cooling device (s) and / or heating device (s) and the side walls. fresh air intake apertures are provided in a portion of the preparation space. The invention also relates to a method for maintaining and supplying fresh air in the cargo compartment of a vehicle superstructure consisting of a transport space and a preparation space during the transport of a sun-wing.

In practice, sunflowers are transported in unit loads, ie plastic crates or paper boxes in truck-mounted superstructures. These carriers or containers designed for the transport of sunbirds have a similar geometric size, with a rectangular shape. In the superstructure, several columns of stacked containers are placed. Usually, 14 pieces of plastic box can be stacked on top of each other using 3 x 3 pieces, ie nine pieces of paper box, using intermediate cross-brackets. Depending on the species (weight) of sunflower in the unit load, 20-100 sunflowers can be placed. Poultry hatching for a few days, called chickens, ducks, geese, turkeys, etc. The temperature of sunbirds is 40 ° C. Their own weight, depending on the breed, is 40-160 grams.

Although physiologically different, these varieties have the same basic conditions of transport as they are transportable.

The transport vehicle carrying the superstructure is practically irrelevant to the transport of the wings. An important consideration when choosing is that the amount of sunflower to be transported, when placed in unit loads, can be placed in the cargo compartment of the superstructure that can be built on the running chassis. These can be latitude and longitude limits. As the size of the unit load (plastic box, paper box) is known, the size of the required cargo space can be easily calculated.

The requirement for a hatchback carrier structure is that the amount of hatchery that you want to carry can be placed in the cargo compartment of the superstructure and that the necessary physiological conditions of the shipment are maintained throughout the transportation. Physiological conditions required: uniform internal storage temperature, independent of external temperature (weather), adapted to the particular number of consignments; it is advantageous if this is provided in a controllable manner by the driver of the vehicle from the driver's cab, as well as continuous air exchange. Required storage space temperature depending on the type and weight of the delivered fowl: 25-29 ° C. Continuous air exchange should ensure the fresh air requirements of the cargo at all points of the load compartment and should not cause drafts.

GB 1,110,471 discloses a vehicle superstructure in which the consignment is surrounded by an air-permeable roof and sidewalls, and fans are provided with the necessary air flow. In this solution, the airflow around the shipment is not properly directed because there is no forced flow that would properly deliver the air into the space between the compartments.

A solution for a somewhat tempered and flowed air supply is described in Soviet patent SU 1523427. In this embodiment, the superstructure already consists of two parts. From a cargo space and a kind of air mixing space. This solution has several disadvantages, despite the fact that a two-part design is used, i.e. the first compartment serves for air flow and the second compartment serves for the storage of the cargo. On the one hand, the air flow is not properly controlled, ie storage devices at a distance from the air flow do not receive the same heat exchange, and on the other hand, the air flow is not sufficiently controlled

EN 224 718 Β1 is designed in a manageable manner and mechanical equipment such as a fan is also housed in the body.

The solution disclosed in Soviet Patent Application SU 713723 is similar to the above and has the disadvantages.

An improved version of these is described in Russian patent application RU 2 023 605, where devices for adjusting and controlling the proper temperature and humidity are located in the front part of the two-piece body and on its front wall above the cab. However, the former air-mixing space was basically designed as a mechanical space where air-mixing is very inefficient. Inadequate airflow remains unchanged.

A common disadvantage of all known solutions is that it cannot provide the required airflow between the compartments forming the consignment.

Our goal was to create a superstructure that ensures continuous air change during transport - adjustable to the amount of cargo. Provide a constant and adequate hold temperature and oxygen supply for the entire shipment around the set value, with the necessary heat removal from the shipment and fresh air supply. In addition, we had to develop an airflow system that meets these requirements without drafts to protect the integrity of the consignment.

It has been discovered that by dividing the superstructure into two spaces, the mechanical space and the air mixing space are formed as a preparation space, the upper part of which is discharging the prepared air into the container through nozzles formed in suspended ceilings and vents in the lower part of the side wall. through the outdoors, then the goal set can be achieved. It has also been found that by placing the nozzles above the corridors between the storage compartments, a good airflow can be achieved.

Thus, the object of the present invention is a sun-winged superstructure consisting of a roof element, sidewalls, front wall, rear wall and floor to maintain the cargo at a suitable temperature and to provide fresh air. The superstructure consists of two spaces, the cargo space for the load and the preparation area. Between the two spaces, a limiting element is provided to allow air flow between the two spaces. Optionally, the preparation space is provided with mechanical equipment for generating the appropriate air temperature, comprising at least one cooling device and / or heating device. Fresh air intake openings are provided in the preparation area of the side walls. Air produced by external or mechanical equipment is introduced into the preparation space. An air inlet is provided in the upper part of the enclosure, under the roof member, over the entire width of the superstructure, with a duct opening for air ducts, defined by a ceiling covering the entire cargo space, above the roof space and above the ceiling. mounted. An airflow device, preferably an outlet nozzle (s) for the blower fan (s), is fitted to the inlet of the fan cabinet, the inlet (s) of which are introduced into the preparation space. Nozzles forming the outlet of the duct are located on the suspended ceiling. Ventilation opening (s) is provided in the side walls of the side walls defining the transport space.

Preferably, the refrigeration unit forming an integral part of the mechanical equipment is an air conditioner, preferably a bus air conditioner, the heater is a hot air blower.

Optionally, buffer accumulators, as well as control and actuating units, are electrically connected to the control unit located in the cab, in the preparation space.

Preferably, the preparation space is provided with a door on the side wall of the superstructure. Preferably, the fresh air intake opening (s) is located on both sides of the preparation space, just below the roof member, and is provided with a rain guard.

The invention also relates to a method for maintaining and supplying fresh air in the cargo compartment of a vehicle superstructure consisting of a transport space and a preparation space during the transport of a sun-wing. In the process, air is produced in the preparation room at a temperature of 16-24 ° C, which is preferably forced into a duct by means of an airflow device mounted on a fan cabinet, flowing from the duct through the nozzles to the conveying space and vented through the side openings.

If the ambient temperature is outside the temperature range of 16-24 ° C, the temperature of the air in the preparation space is cooled or heated to a temperature range of 16-24 ° C by means of a cooling device or heater forming part of the machinery.

Detailed Description of the Invention The present invention will be described in detail with reference to the drawings.

Figure 1 is a side view of the vehicle and the body is a sectional view taken along the line 1-1 in Figure 2;

Figure 2 is a rear view of the vehicle and the body is a sectional view taken along line II-II in Figure 1;

Figure 3 is a side view of the vehicle.

The roof of the body 1 according to the invention (Fig. 1) is bounded by the roof element, the sides by the side wall 3, the front by the front wall 4, the rear by the rear wall 5 and the bottom by the floor 6. Between the sidewalls 3 of the superstructure 1, a barrier 9 having a height dimension less than the height of the superstructure 1 is placed on the floor 6. The opening thus formed between the limiting member 9 and the roof member 2 over the entire width of the superstructure 1 is the air inlet 10. The limiting element 9 divides the body 1 into two parts, the transport space 7 and the preparation space 8. Transport space 7 is transport 27 (perforated side wall re3

EN 224 718 Β1 (boxes, crates), the preparation space 8 is used to accommodate the mechanical equipment and premix the air. The conveying space 7 is completely covered by the ceiling 11 so that the lower edge of the air inlet 10 is aligned with the entire width of the conveying space 7, i.e. the superstructure, and extends approximately parallel to the roof element 2 up to the rear wall 5. The air inlet 10, the roof element 2, the false ceiling 11, and the side walls 3 and the rear wall 5 above the false ceiling 11 form a duct 12. The inlet duct 12 has an inlet 13 in common with the air inlet 10 and an outlet 14 for the nozzles 15 in the false ceiling 11. Parts of the side walls 3 in the transport space 7 are provided with ventilation openings 16 (Figures 2 and 3).

In the preparation space 8 is located a control and operating unit 24 controlling the operation of the heating device 17, the cooling device 18, the air flow device 19, the fan cabinet 22, the buffer battery (s) 23 and the mechanical equipment. The fan cabinet 22 extends from the roof element 2 between the side walls 3, to a certain extent across the entire width of the boundary element 9. At the bottom of the fan cabinet 22 are airflow devices 19 (preferably fans, air turbines) such that their suction opening 20 draws in air from the preparation space 8 and blows air through the inlet 31 of the fan cabinet. The outlet 21 of the fan cabinet 22, through which the air blown by the airflow devices 19 leaves the fan cabinet 22, is tightly fitted with the air inlet 10 and the inlet 13 (Fig. 1). The fan cabinet 22 may also be located in the conveying space 7, since the outlet opening 21 may still be connected to the inlet opening 13 of the duct 12. In this case, the suction opening 20 of the airflow devices 19 draws in pre-mixed air from the preparation space 8. That is, the suction opening 20 is guided through the boundary 9. This embodiment is not shown in the drawing, as it is to be understood by one of ordinary skill in the art that it is to be carried out. The preparation space 8 is provided with a door 25 which opens directly into the preparation space 8 on one of the side walls 3. The two side wall portions 3 delimiting the preparation space 8 are provided with suction openings 26 under the roof element (Fig. 3). The control and actuator 24 can be adjusted or controlled by the control unit 28 located in the cab 29 and connected to the control and actuator unit by cable 30.

The operation of the superstructure 1 according to the invention and the method of keeping the sun wing in the superstructure at a suitable temperature and supplying it with fresh air according to the invention will now be described by way of a practical example.

Measurements and tests showed that if the outside fresh air was continuously supplied to the container at a temperature of about 18-22 ° C, at a body temperature of 40 ° C, the sunflower would provide such a heat release that the shipment would be visible and audible. the temperature of the container 7 is about 25-29 ° C. The weather conditions in Central Europe are such that the average daily temperature is around 20 ° C for several months, and during the rest of the season, similar daytime temperatures may occur for several days. In this case, the outside air required for continuous air exchange can be introduced directly into the conveyor space without tempering (here, cooling or heating of the air). In extreme cases it can be -20 ° C or +30 ° C outside. At lower ambient temperatures, the air supplied to the container 7 needs to be heated, and at higher ambient temperatures, cooling is required. In the first approximation, the nature and technical solution of the heating and cooling equipment 17 seems irrelevant and can be solved with hot water or air heater, or with a cargo space cooler or air conditioner. Fresh air of the correct temperature or temperature should be conveyed to all points of the container 7.

All sides of the carrier 27 (plastic box, paper box, crate) of the shipment 27 are perforated, with openings of a size that the transmitted sunflower cannot escape through, while allowing the transverse air currents. Its bottom is either closed paper (paper box) or covered with a closed sheet of paper with a similarly closed sheet of paper. The carrier means can be arranged in a column-like manner in the transport space 7 (FIGS. 1, 2). This is important because during the exchange of air, the supplied air must be circulated in the container 7 so that the draft 27 cannot be exposed to draft. The higher velocity air currents occur in the corridors formed when the shipment 27 is arranged in the superstructure 1, while the perforated sidewalls of the boxes have an air velocity nearly one order of magnitude lower. Our annual average weather requires the air to be cooled during the greater part of the year, which is why the heating and cooling system must be installed in the body of used vehicles throughout the year.

Effective heat exchange can be achieved by creating a greater temperature difference or by supplying air at a higher rate. It is advantageous to use a bus climate as a cooling unit 18 for cooling the container 7. In practice, a cargo cooler is usually used to cool the load compartment. The bus air conditioner has been developed for operating conditions and operating conditions where the outside temperature can be as high as +30 ° C. Generally, the cabin temperature should be 7 ° C lower than the outside temperature. The air conditioning system must ensure the heat dissipation by cooling, not in a closed space, but in a continuous or continuous operation in cooperation with other equipment (supply fans) to ensure a comfortable air exchange for the comfort of the occupants. It also has its own fan blower. In contrast, cargo coolers cool a closed space, providing the required core temperature of pre-cooled or deep-frozen goods. Air exchange is purely and unintentionally, but it is necessary to move goods4

EN 224 718 Β1, it is created between the outside air and the load compartment when the doors are opened for a relatively short period of time. Their operating temperature is 0 ° C - 20 ° C.

As a heater 17 for heating the container 7, it is preferable to use a hot air blower. These units reach operating temperatures within a minute or two. Their throat temperature is 120 ° C. They have their own blower fan. They are not exposed to frost in their off-mode condition, and there is no risk of water run-off. In contrast, water systems have higher heat inertia, can only be heated to 80 ° C, and take longer to heat up. The high throat temperature of the hot air blower does not allow the use of its own blower fan to direct the heated air directly into the conveying space 7, as it is undesirable to supply the blown cooled air of the air conditioning chiller 18 directly into the conveying space 7. To solve these problems, the preparation space 8 is also used as a ventilation space for premixing. The preparation space 8 is separated by a limiting element 9 made of a thermally insulated panel at the breast wall of the transport space 7, over the entire width of the superstructure 1. The barrier 9 divides the interior space of the body 1 into a conveying space 7 and a preparation space 8 in a non-complete cross-section. In our example, the top edge ends 100 mm from the roof 2. Through the door 25 formed on the right side wall 3 of the superstructure 1, the interior space of the preparation space 8 is accessible. The length of the preparation space 8 is 900 mm. Its width is equal to the width of the superstructure 1. In this preparation space 8 are located all the mechanical and technical equipment of the superstructure 1, such as the refrigerating device 18: an indoor unit of the bus air conditioning (an outdoor unit is located on the roof element 2 or on the front wall 4 of the superstructure); the heater 17: the heat blowers; fan cabinet 22; airflow device 19: blower fans; the buffer battery (s) 23; the control box (relays, fuses) of the control and actuator unit 24.

Through the front door 25, which is opened on the side wall 3, all technical and mechanical equipment is accessible so that all its components can be operated and repaired without the need to move the shipment 27 for intervention. On each side wall 3 of the preparation space 8, three fresh air intake openings 26 are provided, directly below the roof element 2, with a protective grille. The suction openings 26, with the exception of the two upper elements, do not open directly into the preparation space 8. A baffle plate on each side directs the fresh air inflow to the roof element 2.

The fan cabinet 22 is mounted on a panel forming a boundary 9 separating the transport space 7 from the preparation space 8. It has a narrow, box-like design. The preparation space 8 extends over a width of 1200 mm from the roof element 2. Its depth is 120 mm, i.e. its face is 120 mm away from the panel of the limiter 9. The airflow device 19 is formed by radiax blower fans mounted on the bottom plate of the fan cabinet 22. These can be 4-6 air conditioners with the number and capacity of the sunflower to be transported, for example 1000 m ³ / h / pc. These fans suck axially into the suction opening 20 the tempered air of the preparation space 8. Because their outlet nozzles 32 are closely matched to the inlet 31 on the bottom plate of the fan cabinet, the air (blown into the fan cabinet 22) discharged by them toward the roof member 2 exits the fan outlet 22 and collides with the outlet port air inlet to the duct 12. The outlet 21 in our case is 100 mm high and has the same width as the body 1. In order to ensure that the air from the air duct 12 to the conveying space 7 is as uniform as possible, the following procedure is followed. The suspended ceiling 11, which is 100 mm from the roof element 2, covers the entire cargo space 7 and is opened with ducts 12 of the same cross section as follows: the duct 11 runs around the two side walls 3 of the cargo space 7, back wall along eyebrows. Furthermore, a duct 12 is located along the entire length of the container 7, above the corridors between the rows 27 of the shipment, according to the distribution of the rack. In the ceiling 11, in the middle of its longitudinal axis, a double serial duct 12 is formed. The inflow air flows through the outlet 14 of the nozzles 15 flushing down the side walls 3, the rear wall 5 and the limiter 9 vertically, since the side walls 3 are evenly spaced 100 mm over the floor 6 and open to the outside 16 they have ventilation openings. The vents 16 are covered (not shown) by a gilled sheet cover forming a duct to ensure a uniform flow of the supply air. Because of its sloping design, the air is forced to flow up to the floor 6, where it turns back out of the transport space 7 through the vents 16. The heat transfer, heat dissipation (tempering) processes in the preparation space 8 may be as follows.

If the outside temperature does not require temperature control (outside air temperature is 16-24 ° C). The desired cargo space temperature in the container 7 can be adjusted or controlled by varying the airflow capacity of the airflow devices 19, namely the blower fans. The blower fans can be operated in three stages. The speeds can be set at the same time by means of a selector switch for each fan, ie all fans I or II. or III. works in gear. This is important because in this way, the fans in the duct 12 create a uniform overpressure with uniform airflow. The nozzle system consisting of nozzles 15 is dimensioned such that overpressure is already generated when all fans are running in stage I. Due to the overpressure in the nozzle system with longitudinal nozzles 15 having the same orifices 14

EN 224 718 Β1 the same amount of air is distributed to each point of the conveyor 7. From the nozzles 15, a curtain of air flows from the top down to the vents 16 of the side walls 3. The longitudinal corridors of the shipment 27, arranged in columns and rows, are continuously flushed with a vertical, downward flow of air. At the same time, the resulting turbulence creates a transverse air movement, which velocity is significantly lower than the vertical air movement, as it flows through the pierced sidewalls of the storage devices, providing ventilation. Thus, due to the higher velocity airflow between the corridors between storage devices, the temperature of the corridors is always lower than the temperature inside the crates. This temperature difference ensures that air flows out of the storage devices. According to our measurements and tests, the fans can deliver enough fresh air to the 7 compartments even when transporting at full weight in stage I. The amount of air is safely sufficient to supply oxygen to the entire shipment 27 and to provide the necessary heat extraction so that the temperature of the container 7 does not rise above 29 ° C, a user demand based on measurement experience. This temperature can be measured in the corridors between the storage means of the shipment 27. Of course, the temperature inside the crates is higher because of the body temperature of the birds at 40 ° C. As the temperature of the container 7 rises, the fans can be suppressed II. then lll. gear. Naturally, as the air velocity increases, the heat dissipation increases.

If the temperature of the container 7 continues to rise or fall, the air conditioner 18 or the heat blower 17 used as a heater 17 must be started. At this point, the airflow devices 19, i.e. the fans, must be switched back to stage I, since the fans running at a higher stage reduce the efficiency of the heat dissipation. Higher masses at higher speeds can be cooled more efficiently by the air conditioner. This may result in a slower decrease or stagnation of the temperature of the container 7, but may result in an increase, for example at higher outside temperatures and higher air velocities. The basic point is that when operating either the air conditioner or the heater blowers, the fans cannot be switched above stage I.

By installing the air handling units described in the example, the conveyor 7 is capable of providing a full mass solar wing capacity of up to an external temperature of 30 ° C at a relative humidity of 40% of the outside air. Above 80% relative humidity this temperature is 26 ° C. In case of limit temperature conditions the quantity to be delivered must be reduced!

Two of the buffer accumulators 23 can accommodate two 85 to 100 Ah 12 V voltages in the preparation space 8 so that an occurrence of a technical failure in the conveyor does not damage the shipment 27.

The superstructure 1 constructed according to the invention is suitable for transporting both a paper box and a plastic crate, as well as a container sunflower such as a chick in a container.

The main requirement of superstructures and air-conditioning systems constructed according to the invention for the transport of sunflowers is to provide the complex cooling, heating and air-conditioned supply of fresh air required for the transport of high-quality sunflowers. This state of the art can be achieved by automatically operating a control and actuator 24. It may be more cost-effective if the driver, depending on the outside temperature and weather conditions, decides to switch the system to heating or cooling mode, or to provide the proper transport space temperature and fresh air directly by supplying the ideal outside air. To do this, the control unit 28 must be set to the appropriate environmental conditions which are transmitted to the control and actuator unit 24 via cable 30, which intervenes in accordance with the instructions to operate the mechanical equipment.

The temperature of 25 to 29 ° C should prevail in the 7 compartments, irrespective of the weather conditions. The temperature of the preparation space 8 must be set by the control unit 28 so that this condition is met. The digital display instrumentation of the control unit 28 in the cab 29 shows the temperature of the preparation chamber 8, and its sensor is located in the vicinity of the suction opening 20 of the airflow fans 19 in the preparation chamber 8 as part of the control and actuator.

The temperature of the cargo compartment 7 can be varied by means of a control unit 28 which is located in the cab 29 and is digitally displayed on the temperature control unit. The temperature sensor of the container 7 is located in the middle of the container 7 at the height of the upper part of the container 27 (not shown). This starts or stops the chiller 18 or the heater 17 within the set limits according to the cooling or heating mode. The controlled temperature of the preparation space 8 provides the set temperature of the transport space 7. In the heating mode, the top temperature of the 8 preparation rooms is set to 40-45 ° C, while in the cooling mode, this value is set to 18-22 ° C. At ambient temperatures of 16-24 ° C, the 27 loads do not require any cooling or heating, just the right amount of air exchange. The airflow power of the three-stage fans can be controlled by a switch from the control unit 28 built into the cab 29. The system operates automatically when the fans are correctly selected. In heating mode, when the temperature of the preparation space 8 or the transport space 7 reaches the set upper limit, the control unit 28 disables the operation of the heating device 17 via the control and actuation unit 24, or resets the heating device 17 when the temperature falls below the set value. In cooling mode, the reference temperature of the chiller 18 (heat on the indoor unit6)

EN 224 718 Β1) must be set so that the required temperature of the preparation space 8 remains within the required value. Each of the control and display elements is located in the control unit 28 located in the cab 29.

At very low outside temperatures, the throat air of the heater 17 can be directed to the suction openings 20 (not shown) of the airflow devices 19 by means of lance tubes.

An advantage of the sun-wing transport superstructure according to the invention and the method related thereto is that it is possible to ensure that the consignment is delivered intact and healthy. All this by means of a superstructure implemented by simple means, which prevents the shipment from being exposed to drafts by providing air preparation (fresh air intake and temperature) in the preparation room and directed outflow from the duct, while ensuring the necessary environmental conditions. The technical equipment of the superstructure can be automated up to the level which eliminates the need for human intervention during transport, but it requires only a simple operation by default. The mechanical components of technical equipment are ready-made, not unique, so they do not represent a disproportionate increase in costs. The cost of the superstructure is quickly reimbursed by delivering the shipment without damage.
