公報）。In recent years, particularly in urban areas, severe heat is generated in summer. At this time, the load of the cooling operation of the air conditioner increases. In this case, there may be inconveniences such as a malfunction of the cooling due to a decrease in the cooling capacity, and in some cases, a stop of the machine and a failure in operation. In order to solve this problem, there is known an auxiliary cooling device for an air-conditioning air-cooled condenser in which fine particles or mist-like water is sprayed almost uniformly to radiation fins of the air-cooled condenser (Japanese Patent Laid-Open No. 10-213361). ).

能を大幅に低下させるという問題点があった。[0006] The technique described in Japanese Patent Application Laid-Open No. Hei 5-10551 is to disperse drain water generated during cooling operation to a heat exchanger on the condensing side. In this method, a water supply source is not required, and a place where the water supply source can be installed is not limited. However, since the drain water usually contains a large amount of dirt such as mold on the indoor heat exchanger, spraying the drain water directly to the heat exchanger on the condensing side may cause clogging of the outdoor heat exchanger. This causes a problem that the performance is greatly reduced.

光窓６が設けられている。FIG. 1 is a structural view of an outdoor unit 100 of an air conditioner of the present invention. The casing 1 includes a fan 2, a heat exchanger 5, and the like. The fan 2 is connected to a motor 3, and a bell mouth 4 is provided on the outer periphery. In the present invention, the fan 2 and the bell mouth 4 are made of a metal such as aluminum, so that light is easily reflected. The heat exchanger 5 is a product in which a plurality of tubes 52 are arranged on a plate-like fin 51 in which a plurality of thin aluminum plates are stacked. In the present invention, a photocatalyst such as titanium dioxide is applied to the entire surface of the plate-like fin 51. Above the heat exchanger 5, a drain water distributor 7 is provided. In the distributor 7 of this embodiment, a porous body 71 containing a photocatalyst is inserted into a cover 72 having a large number of holes 73 on the lower surface. A drain pan 9 is provided below the heat exchanger 5 via a porous body 8. The drain pan 9 also serves as a reflection plate, and the porous body 8 protrudes between the plate-like fins 51. Furthermore, above the distributor 7 lighting window 6 having a reflecting plate 10 on the outer peripheral portion is provided.

る。In such a configuration, when the air conditioner performs the cooling operation, the drain water generated in the indoor unit 200 flows from the upper end of the outdoor unit 100 after passing through the drain pipe 300 by the action of gravity. It flows into the outdoor unit 100. Outdoor unit 10
Drain water flowing into 0 is distributed by the distributor 7 flows between the plate-like fins 51 of the heat exchanger 5 substantially uniformly. At this time, since dirt such as mold is filtered by the porous body 71, the plate-like fins 51 are removed.
The drain water flowing between them does not contain much dirt such as mold. Plate-like fins 51
The drain water flowing therebetween evaporates while spreading evenly on the plate-like fins 51. Due to the evaporation of the drain water, the heat exchanger 5
Allows sufficient heat radiation even if the temperature difference between the heat transfer tube 52 and the air is small. Therefore, sufficient cooling performance can be achieved even in midsummer, when the outside air temperature is extremely high. In addition, this reduces the discharge pressure of the compressor, which lowers the compression ratio, thereby improving the operating efficiency of the compressor.As a result, the efficiency of the refrigeration cycle increases, and energy saving is achieved.

The entire lower end portion of the plate-like fin 51 is wetted again via the fin 8.

を持続させることが出来る。Ultraviolet rays incident from the daylighting window 6 and the bell mouth 4 are repeatedly reflected by the reflector 10, the inner surface of the fan 2, the bell mouth 4, the drain pan 9 and the like, so that the heat exchanger 5 and the distribution unit 7 are evenly irradiated. At this time, since the ultraviolet rays incident from the lighting window 6 and the bell mouth 4 always refresh the photocatalyst, the porous body 71 and the plate-like fins 51 are used.
In addition to decomposing molds and other stains, excellent hydrophilicity can be maintained.

房運転時の運転効率や快適性が向上する。Usually, during the heating operation, the heat exchanger 5 functions as an evaporator. In this case, since the air volume is reduced due to the formation of frost on the plate-like fins 51 on the most upstream side of the air flow, a decrease in the heating capacity is apt to occur. The frost grows over the entire area of the fins and does not grow locally at the upstream end of the plate-like fins 51 because they are not stained and the hydrophilicity is maintained. Therefore, maintaining the performance of the evaporator for a long time greatly increases the time interval until the defrosting operation is performed, and improves the operating efficiency and comfort during the heating operation.

If the indoor unit 200 has a drain pump, it does not depend on the height difference between the indoor unit 200 and the outdoor unit 100.
