It is an arrangement sectional view showing the conventional elevator air conditioner shown in the publication. In the figure, 1 is an evaporator (not shown)
It is a water storage tray for storing the drain water 100 generated in 1. and is provided below the heat exchanger 3 acting as a condenser, and is partitioned by the partition plate 2 into the A side of the lower part of the condenser and the B side communicating with it. .

Further, the drain water 100 generated by an evaporator (not shown) is constructed so as to be introduced to the A side, and the A side has a heat exchanger 3 acting as a condenser, a pump 4, and a discharge port of the drain water 100. 5, a pipe 6 that connects the pump 4 and the discharge port 5, a diffusion plate 7 for the discharged drain water 100, and a water level detector 8 for starting and stopping the pump are arranged.

Further, the partition plate 2 is constructed so that a part or all of the upper end thereof is lower than the upper edge of the outer peripheral portion of the water storage tray 1 so that the drain water once stored on the A side can overflow to the B side. Further, a heater 9, a water level detector 10 for energizing the heater, and a water level detector 11 for stopping the compressor are arranged on the B side of the water reservoir 1. Reference numeral 12 is a heat radiating fan of the condenser (hereinafter referred to as a fan).

Next, the operation will be described. When the drain water 100 generated by the evaporator (not shown) reaches a predetermined water level on the side A in the water storage tray 1, the pump 4 is operated by the water level detector 8 and the drain water is discharged from the discharge port 5 through the pipe 6. Let The water collides with the diffusion plate 7 and is sprayed into the heat exchanger 3 acting as a condenser, and is evaporated by the heat of condensation of the refrigerant during its natural fall.

When the drain water treatment device on the A side alone does not completely evaporate, the drain water 100 passes through the partition plate 2 and overflows from the A side to the B side, so that the heater 9 is energized by the water level detector 10. Drain water is heated to evaporate.
Further, when the heater 9 does not reach the drain water evaporating capacity, the water level detector 11 stops the compressor (not shown) to stop the drain water generation itself in the evaporator.

[0008]

【Example】

Example 1. Hereinafter, the first and thirteenth inventions will be described with reference to the drawings. 1 to 3, reference numeral 20 denotes an air conditioner installed, for example, at the top of the outside of a car of an elevator (not shown) that moves up and down a predetermined space in a building or the like, and a compressor 21 that compresses a refrigerant gas, A condenser 22 that liquefies the compressed refrigerant gas by radiating heat, and an evaporator 2 that evaporates the liquefied refrigerant
It has a refrigerating cycle in which devices such as No. 3 are connected by a refrigerant line 24. Reference numerals 25 and 26 are water storage trays provided below the condenser 22 and the evaporator 23, respectively, and are connected by a pipe 27.

Reference numeral 28 denotes a water supply device 30 such as a drain pump, which receives drain water sent from the water storage tray 25 of the condenser 22 and drops water from the drain water dropping hole portion 29 on the upper surface of the condenser 22 in a wide range. This is a drain water dropping device. FIG. 2 is a partially enlarged view of FIG. 1, and 31 is a cloth-plate-like water retaining member made of a fibrous or non-woven material (for example, felt), which is an upper part along the shape of the upper surface of the condenser 22. It is provided on the entire surface, and a predetermined space is provided between the drain water dropping device 28 and the lower surface thereof.

Here, the predetermined interval means that there is a sufficient space between the drain water dropping device 28 and the water retaining member 31 so that the water droplets can leave the drain water dropping device 28 and fall freely. Reference numeral 32 denotes a blower provided on a side portion of the condenser, and here, a case where air is blown from the fan 32 toward the condenser 22 is shown.

Next, the operation will be described. Due to the operation of the air conditioner 20 associated with the elevation of the elevator, the water generated on the surface of the evaporator 23 drops and the drain water 1
It collects as 00. The drain water 100 is introduced into the water storage tray 25 provided at the lower portion of the condenser 22 by the pipe 27 to become stored water. When this drain water reaches a predetermined amount, a water level detector (not shown) operates a water supply device 30 to introduce water from the water storage tray 25 into the drain water dropping device 28.
As shown in FIG. 3, a plurality of drain water dropping holes 29 provided on average are dropped downward.

This drain water passes through a predetermined space and then the water retaining member 3
First, it is dripped in a dot shape on the No. 1 and then, while being diffused in the water retention member 31 in the lateral direction, is guided to the lower side, and is almost evenly adhered to the surface of the condenser 22, for example, the surface of a cooling fin (not shown). Pass water downward. At this time, since the condenser 22 is heated to approximately 50 to 60 ° C. by the high temperature refrigerant, the drain water evaporates due to the heat, and the wind force of the blower 32 evaporates it into the atmosphere, so that the space for the elevator is exposed. The air is discharged from the provided ventilation port by an exhaust fan (not shown) or the like. The drain water remaining without being evaporated is guided to the water storage tray 25, and the above evaporation operation is repeated. The water retaining member 31 may be felt, filter paper, cloth or the like. The suitable drain water pilot hole 29 shown in FIG. 3 is not limited to a circular shape, but may be an elliptical shape, an elliptical shape, a square shape, or the like.

Since the dust is removed by the water retaining member 31, it is less likely that the fins of the condenser will be trapped with dust and the heat dissipation effect will be deteriorated. Lower surface of drain water dropping device and water retaining member 31
Since there is a proper gap between the holes, the hole 29 is not clogged with dust. The dust is taken into the water retaining member 31 and does not accumulate on the fins of the condenser.

Embodiment 2 FIG. The drain water suitable prepared hole portion 29 of FIG. 3 of the first embodiment needs to have a large number of holes in order to sufficiently diffuse it. However, if the diameter of the holes is too large at this time, the water is lowered before the water reaches the entire surface. The hole must be reasonably small, as it will fall into. However, if it is too small, there is a problem that the required amount of water cannot be obtained. Therefore, even if the diameter of the hole is small, it is necessary to devise so that water can pass through well.

FIG. 4 shows a second invention for such a purpose. In the figure, those having the same numbers as those of the first embodiment show the same or corresponding parts, and therefore detailed explanations thereof will be omitted (hereinafter, referred to as "first embodiment"). Same for each figure). The drain water dropping device 28 is placed in contact with the upper surface of the water retaining member 31 attached to and attached to the upper surface of the condenser 22. In this state, from the water tray 25 to the water supply device 3
The drain water guided at 0 is discharged into the drain water dripping device 28, directly flows out from the drain water dripping hole 29 to the water retaining member 31, is absorbed and diffused, and is uniformly guided to the surface of the condenser 22. Evaporation processing is performed by the same operation as 1. Direct contact between the drain water dropping hole 29 and the water retaining member 31 facilitates absorption of drain water by the capillary action.

Example 3. In the method of the second embodiment, since the water retaining member 31 is in contact with the drain water proper prepared hole 29, dust is apt to be clogged here. A third aspect of the invention, which is an improvement over this, will be described.
FIG. 5 and FIG. 6 show the third invention, and in FIG.
Reference numeral 3 is a laminated portion in which an end portion of the water retention member 31 is bent upward and overlapped, and 34 is a space portion. The rest of the configuration is the same as that of the second embodiment, so the description is omitted.

Water retaining member 3 attached to the upper surface of the condenser 22
When the drain water dropping device 28 is installed in contact with the upper surface of the laminated portion 33 at the end of No. 1, a slight space 34 is formed between the lower surface of the drain water dropping device 28 other than the laminated portion and the upper surface of the water retaining member 31. Is formed. A drain water dropping hole portion 29 having a small diameter (smaller diameter when the hole is elongated) is provided on the lower surface of the drain water dropping device facing the space portion 34.

In this state, similarly to the second embodiment, the drain water introduced from the water storage tray 25 to the drain water dropping device 28 hangs downward from the drain water dropping hole portion 29 having a small diameter and has a substantially hemispherical shape due to the surface tension. It gradually increases while forming. At this time, the surface tension of the water acts in the direction of pulling the water upward, and acts in the direction of decreasing the amount of water. However, when the drooping lower end reaches the water retention member 31 in time, the surface tension acts so as to pull the water downward. When the size of the space 34 is appropriately adjusted, this operation is continuously performed and the drain water is sequentially introduced to the surface of the condenser 22, so that the water has a continuous columnar shape.

It is preferable that the size of the space portion 34 is substantially the same as the diameter of the drain water proper prepared hole 29, for example, about 1 to 2 times that. This is because if it is narrower than this, the water retaining member 31 becomes a shape that closes the hole, and dust is likely to be clogged, and if it is larger than this, the water breaks and falls. When the water is flowing in a columnar shape, the surface tension pulling the water upward hardly works, so that the passage of the water becomes better even with the same hole size than when dropping the water.

In the above-mentioned embodiment, the laminated portion 33 shows the water retaining member 31 which is bent. However, according to the hole diameter of the drain water dropping hole 29, a member having a predetermined thickness is laminated to form an optimum space. The part 34 may be provided. In this way, the water is guided to the water retaining member 31 in the form of a water column instead of the water droplets, so that the amount of dropping is constant and reliable dropping is possible.

When the drain water mixed with dust and the like flows out from the drain water dropping hole portion 29 to the water retaining member 35 during operation, if the water passage member 35 is a cloth plate, this dust is accumulated on the surface and closes the hole portion. Although water can be prevented, dust is not accumulated due to the net-like shape and the large space.

The drain water dripping device 28 is supported by a support frame (not shown) by contacting the upper surface of the wavy water retaining member 50 which is placed on the upper surface of the condenser 22 and has a continuous wavy shape in one direction.

At this time, since a part of the corrugated water retaining member 50 is in contact with the drain water dropping hole 29, the drain water meanders along the corrugated water retaining member 50 in a cooling fin (not shown) of the lower condenser 22. Is dropped on. Since the operation thereafter is the same as that of the second embodiment, the description thereof will be omitted. The wavy water retaining member 5
0 may be provided in a wide width on a plane, or may be provided in a narrow width so that a plurality of corrugations are formed between the pitch intervals of the drain water dropping holes 29, thereby increasing the effect.

Example 20. FIG. 24 shows a twelfth aspect of the invention, in which 49 is a suction fan which is arranged so that its suction port faces the condenser 22 and its discharge port faces upward. The rest of the configuration is the same as that of the first embodiment, so the description is omitted. As in the first embodiment, the drain water introduced to the drain water dropping device 28 is dropped onto the water retaining member 31 through the drain water dropping hole portion 29, and is evaporated by the self-held heat while dropping the surface of the condenser 22 while diffusing. To do.

The evaporated water and the water scattered by the wind are sucked from the lateral direction by the suction fan 49 and discharged from the discharge port upward with a predetermined wind force, and are provided above the elevator space and exhausted from the ventilation port. It is discharged to the outside by a fan (not shown). Further, the water sucked into the fan in the form of water drops adheres to the inside of the wall surface of the fan case by the centrifugal force of the fan, and then is drained from the water drain hole 60 at the bottom of the fan to the water storage tray 2.
Recovered within 5.

Although the above-mentioned Examples 1 to 20 are installed on the top of the elevator car outside the room, they may be installed outside the floor underneath, and the drain water is not limited to the self-treatment. It can also be installed on equipment that requires wastewater, which has the effect of not requiring manpower for wastewater treatment.

EFFECTS OF THE INVENTION According to the first to thirteenth inventions, (1) Drain water can be diffused by the water retaining member to be uniformly diffused on the surface of the condenser, so that the effect of improving evaporation efficiency can be obtained. (2) As a result of the drain water uniformly diffusing on the surface of the condenser, there is no water that does not fall on the condenser and directly drops downward, and the evaporation efficiency is improved. (3) Since the evaporation capacity is improved, it is less likely that the drain water will be accumulated and the air conditioning will have to be stopped. (4) Dust in the drain water is filtered by the water retaining member before being sent to the fan of the condenser, and is not deposited on the fins. The effect is obtained.

In addition to the above effects, the eighth, ninth and twelfth inventions have the effect that (5) the water droplets attached to the fins are not blown outward by the wind force of the cooling fan to pollute the surrounding atmosphere. is there.

According to the ninth aspect of the invention, in addition to the effects of (1) to (5) above, (6) since water can be evaporated in a portion other than the condenser, the evaporation capacity of the entire apparatus is increased. You can There is an effect.
