Description

DRAIN ASSEMBLY AND AIRCONDITIONER INCLUDING SAME

The present invention relates to a drainage assembly and an air conditioner including the same.

In general, a separate type air conditioner consists of an indoor unit and an outdoor unit, and an evaporator, a compressor, a condenser, and an expansion valve are connected to the air conditioner.

In general, a high-pressure service valve and a low-pressure service valve are installed in the outdoor unit, and a refrigerant pipe, which is a copper pipe leading to the indoor unit, is connected to each service valve.

In the separation type air conditioner, the refrigerant gas compressed and heated in the compressor passes through the condenser, and the temperature drops due to contact with outside air, and the refrigerant gas with the temperature lowered is decompressed as it passes through the expansion valve of the indoor unit. As the depressurized refrigerant gas passes through the evaporator, it exchanges heat with the indoor air to cool the indoor air.

Meanwhile, during the cooling operation of the air conditioner, condensed water may be generated in the service valve of the outdoor unit due to a temperature difference. When the outdoor unit is installed on the exterior wall of a building, such condensate may flow along the exterior wall of the building and contaminate the exterior wall of the building. In addition, when the outdoor unit is disposed in the outdoor unit room inside the building, condensed water may flow into the outdoor unit room and contaminate various equipments inside the outdoor unit room, and in addition, water stains and mold may be generated.
