Description

air conditioner

technical field

The present invention relates to an air conditioner, and more particularly, to an air conditioner capable of realizing an assembled type of indoor and outdoor units to improve condensation efficiency.

Background technique

Generally, in an air conditioner, compressed refrigerant gas flows through a condenser (outdoor unit side heat exchanger) and is cooled and becomes a low-temperature and low-pressure liquid gas through capillary tubes. This liquefied gas passes through the evaporator (indoor unit side heat exchanger) into a gaseous state. At this time, a large amount of heat is exchanged to drastically lower the indoor temperature. In addition, the air conditioner can also be used as a heater capable of increasing indoor temperature by realizing the reverse flow of refrigerant gas.

The above-mentioned air conditioners are classified into an indoor unit installed indoors and an outdoor unit installed outdoors.

Therefore, since the installation of the air conditioner requires the installation of indoor and outdoor units, the manufacturing cost is increased, and it is difficult to install the air conditioner.

In order to overcome the above problems, Korean Patent Application No. 33941997 filed by the same applicant of the present invention discloses a self-cooling air conditioner that does not include indoor and outdoor units.

The above-mentioned self-cooling air conditioner excluding an outdoor unit includes an evaporator, a condenser, a capillary tube, a compressor performing a cooling cycle, and they are installed inside a cabinet. The cooling device is installed under the condenser to cool the refrigerant inside the condenser. The cooling device includes a blower fan capable of forcing air in the condenser to circulate, and a cooling water injection unit capable of spraying cooling water to the condenser.

The above-mentioned self-cooling air conditioner that does not include an outdoor unit has the following problems:

First, the cooling water, one of the cooling media used to cool the conventional condenser inside the chassis, can cool the refrigerant inside the condenser, and the temperature of the cooling water rises to 55°C~60°C. The heated cooling water is recirculated and sprayed into the condenser. Therefore, when the cooling water is used for a long time, the temperature of the cooling water rises to a certain degree, so that the refrigerant inside the condenser cannot be cooled to an appropriate temperature.

Due to the large particle size of the cooling water, the cooling water is not evenly supplied to each part of the condenser, thereby reducing the condensation effect.

Second, foreign matter contained in the cooling water may block the injection holes of the injection plate, so that the injection operation cannot be performed and the injection effect is lowered.

Third, air, which is one of the cooling media, circulates in the room and the condenser, and exchanges heat with the refrigerant, so the temperature of the air rises and is discharged to the outside. That is, since the air in the room is used to exchange heat with the condenser, in order to cool the room to a set temperature, the system needs to work for a long time, so the power consumption for driving the compressor increases.

Fourth, the forcedly circulated air is discharged through a discharge port installed in the center of the condenser. Therefore, air gathers and circulates in the central part of the condenser. As a result, the air does not exchange heat with the refrigerant flowing outside the condenser. Therefore, air passing outside the condenser is not discharged but collected in the condenser. The state of the refrigerant changes based on the position of the condenser, so certain errors occur in the cooling cycle.

Still another object of the present invention is to provide an air conditioner capable of preventing an increase in indoor temperature due to air capable of cooling a condenser.

As shown in the figure, the air conditioner according to the present invention includes a casing 1 , a compressor installed in the casing 1 for realizing a cooling cycle, a condenser 3 , a capillary tube, and an evaporator 4 .

The lower compartment of the housing 1 includes a machine room 1a, a condensation room 1b and an evaporation room 1c. The compressor 2 is installed in the machine room 2 . The condenser 3 is installed in the condensation room 1b, so the heat exchange medium exchanges heat with the refrigerant in the condenser 3 .

In the condenser 3, the heat exchange operation is done based on the water cooling method and the air cooling method. The cooling water is turned into small water droplet particles, and the small water droplets are supplied to the condenser 3 . The outside air flows into the condensation room and is supplied to the condenser 3, and is used to exchange heat with the refrigerant in the condenser 3.

The heat exchange medium will be described in detail below.

As the heat exchange medium, there are cooling water and external air. Cooling water is stored in a cooling water storage tank. The ultrasonic vibrating plate 20 is installed at the bottom of the cooling water storage tank 10 for turning the cooling water into small water droplets and spraying them to the condenser 3 .

In addition, an air duct 11 is installed in the cooling water storage tank 10 for effectively spraying water droplet particles to the condenser 3, which is changed in state by the oscillator 21 of the ultrasonic oscillation plate 20. A through hole 22 is formed in the ultrasonic oscillation plate 20 . The air duct 11 passes through the through hole 22 .

A certain amount of cooling water is stored in the cooling water storage tank 10 . A water level sensor “S” is installed in the cooling water storage tank 20 . The controller "C" drives the solenoid valve "V" based on the cooling water level detected by the water level sensor "S", thereby refilling the cooling water stored in the cooling water tank "T".

The guide member 30 is installed on the upper portion of the condenser 3 for guiding the discharge operation of the air. The guide member 30 is formed in a conical shape whose width gradually decreases in an upward direction. An exhaust pipe 40 is connected to one side of the guide member 30 .

The condenser 3 performs a condensation operation based on cooling water and external air, and includes a suction pipe 50 communicating with the outside of the system and a condensation room 1b for supplying external air.

The intake port 51 of the suction pipe 50 is connected to the outside, and the exhaust port 52 is disposed under the cooling water storage tank 10 so that the outside air passes through the cooling water storage tank 10 and the condenser 3 .

Here, a part of the exhaust port passes by the intake pipe 50 . The suction and discharge pipes 40 and 50 form a double structure. The constructed wall surface forms holes for mounting the two tubes 40 and 50, thereby enabling easier mounting.

In addition, a blower 60 is installed at the highest central portion of the guide member 30 so as to forcibly circulate water droplet particles and air. The air circulation guide plate 70 is installed between the blower 60 and the condenser 3 for guiding air circulation.

The air circulation guide plate 70 has a certain size for covering the upper part of the condenser 3 . Air circulation holes 71 are formed thereon. A plurality of air circulation holes 71 are formed in an integral part of the air circulation.

The air circulation guide 30 is slidable in front, rear, left, and right directions based on a driving unit such as a solenoid, a driving motor, and the like. Here, a guide hole 72 is formed at a central portion of the air circulation guide plate 70 . A guide protrusion 73 inserted into the guide hole 72 for guiding the sliding operation of the air circulation guide plate 70 is formed in the case body 1 .

In the drawings, reference numeral 80 denotes a drain plate for draining water formed on the surface of the condenser 3 . The cooling air from the evaporator room 1c circulates indoors to reduce the indoor temperature and flows into the box 1 and the evaporator 1c without passing through the condenser 1b.

The operation of the air conditioner according to the present invention will be described below with reference to the accompanying drawings.

The refrigerant gas compressed by the compressor passes through the condenser 3 to generate a high temperature. At this time, the generated heat is cooled by the heat exchange unit and transferred to the capillary.

Ultrasonic waves are generated based on the oscillation of the oscillator 21 . The water stored in the ultrasonic oscillation plate 20 is converted into water droplet particles and sprayed toward the condenser 3 . Air is made to flow from the lower part to the upper part of the ultrasonic vibration plate 10 through the air duct 11 by the suction force of the blower 60, thereby realizing easier operation of spraying water droplets.

The water droplet particles pass through the condenser 3 and exchange heat with the refrigerant in the condenser 3, thereby receiving heat from the refrigerant and becoming a gaseous state.

The water level sensor "S" measures the water level of the cooling water stored in the cooling water storage tank 10 and transmits it to the controller "C". The controller "C" drives the solenoid valve "V" to maintain the proper level of cooling water based on the current water level delivered by the water level sensor "S". In other words, the cooling water becomes in a droplet state, thereby supplementing the cooling water to the condenser 3 by a certain amount of sprayed water.

The blower 60 makes the outside air flow into the condenser 1 b through the suction pipe 50 and pass through the condenser 3 . The air receives high temperature heat from the refrigerant.

The steam and air are circulated by the circulation force of the blower 60 . The circulation force is realized based on the air circulation holes 71 on the air circulation guide plate 70 . That is, since many air circulation holes 71 are formed on the air circulation guide plate, steam and external air uniformly flow through the entire area of the condenser 3 .

The vapor and the outside air that are heat-exchanged by the condenser 3 flow into the exhaust duct 40 along the guide member 30 through the air circulation holes 71 on the air circulation guide plate 70, and flow continuously along the exhaust duct 40 and are discharged to the exhaust port 41. external.

When passing through the condenser 3 , water droplets are formed on the surface of the condenser 3 based on the temperature difference of the condenser 3 . The water droplets thus formed move to the drain plate 80 along the inclined portion of the condenser 3 .

Therefore, the cooling water passes through the oscillator 21 of the ultrasonic oscillating plate 20 to become small water droplets for heat exchange with the refrigerant flowing into the condenser 3 . Since the water droplet particles are too small, the water droplet particles move to various parts. The cooling water for heat exchange with the refrigerant of the condenser 3 is not reused. That is, cooling water having an appropriate temperature is used, so an appropriate temperature of the refrigerant in the condenser 3 can be maintained.

The suction force of the blower 60 is applied to the water droplets and the outside air flowing in through the air circulation holes 71 of the air circulation guide 70 , so the water droplets and the outside air are supplied to the parts of the condenser 3 .

No internal air is provided for heat exchange operation with the refrigerant in the condenser 3 . That is, in the present invention, external air is sucked so as to prevent an increase in indoor temperature.

As described above, according to the air conditioner of the present invention, the cooling water becomes small particles of water droplets and exchanges heat with the refrigerant of the condenser. Since the cooling water is not reused, it is possible to maintain the set temperature of the internal refrigerant of the condenser.

In addition, the water droplet particles are small and are sprayed to various parts of the condenser. That is, water droplet particles and air do not partially flow to a part of the condenser, thus improving the condensation efficiency of the condenser.

Since the outside air is used as the heat exchange medium, the air temperature can be prevented from rising and the reliability of the air conditioner can be improved.

Since the present invention may be embodied in various forms without departing from its spirit or essential characteristics, it should also be understood that the above-described embodiments are not to be limited by any detail of the foregoing description, unless otherwise defined, should be understood in the appended claims. The spirit and scope defined in the claims are to be construed broadly, and all changes and modifications which come within the terms and metes and bounds of the claims, or equivalents of such terms and metres, are to be embraced in the appended claims.
