In general, the air conditioner is to maintain the optimum temperature and humidity according to all climatic conditions and indoor environment, including a cooling device and heating device to cool or warm the indoor air, and a humidifier to maintain the humidity properly; Ventilation equipment for exhausting indoor air to the outside is included.

Among them, the cooling device uses the phenomenon of absorbing the heat of the surroundings when the liquid evaporates to perform the cooling operation. In addition to the cooling operation, the cooling operation is also performed. In particular, a room air conditioner mainly installed in a small cooling space such as a home or a restaurant is divided into an outdoor unit and an indoor unit. The outdoor unit corresponds to a compressor for compressing a refrigerant and a condenser for condensing the refrigerant. The outdoor unit is installed on the roof or outside of a porch due to noise and heat emission. The indoor unit is a part that evaporates the refrigerant sent from the condenser and supplies it to the room.
