The invention provides a PTAC air conditioner and a fresh air dehumidification method, relates to the technical field, and solves the technical problem that the area of the dehumidifying evaporator of the existing PTAC air conditioner is too small due to the limitation of installation space and the size of the fresh air outlet. The PTAC air conditioner includes a refrigeration system and a dehumidification system that share a compressor, wherein the refrigeration system includes a main evaporator, and the dehumidification system includes a dehumidification evaporator, and the dehumidification evaporator is located on the indoor side of the air conditioner, and is located in the air conditioner. The front of the main evaporator is close to the indoor side. The dehumidification evaporator of the PTAC air conditioner is located on the indoor side of the air conditioner, and is located in front of the main evaporator and close to the indoor side. Since the main evaporator has a large space close to the indoor side, it is no longer limited by the size of the fresh air outlet, effectively increasing The heat exchange area of the dehumidification evaporator is increased, and the dehumidification effect is improved; the above-mentioned PTAC air conditioner is used to dehumidify the fresh air, and the outdoor fresh air is dehumidified twice by the dehumidification evaporator and the main evaporator, and the dehumidification effect has been greatly improved.
Description
technical field [0001] The invention relates to the technical field of air conditioning, in particular to a PTAC air conditioner and a fresh air dehumidification method. Background technique [0002] In order to simplify the control and reduce the cost of the existing PTAC air conditioner, a dehumidification scheme is proposed in which the temperature adjustment system and the humidity adjustment system share one compressor. Because the outdoor fresh air enters the room through the air inlet on the middle partition of the PTAC, the prior art generally uses the fresh air to dehumidify before entering the air inlet of the middle partition, and the dehumidified fresh air enters the room through the air inlet of the middle partition. Set the dehumidification evaporator at the outdoor air inlet (that is, the fresh air outlet), without setting a separate fresh air channel. [0003] The applicant finds that the prior art has at least the following technical problems: [0004] Bec...
