Abstract

The invention discloses a household type air conditioner and an operation method thereof, and belongs to the technical field of heating ventilation air conditioners. The household type air conditioner comprises a heat pump system, a solution humidifying system and a wind control system. The heat pump system comprises a compressor, heat exchangers, two-way expansion valves, a flow adjusting valve and an electric switch valve. The solution humidifying system comprises a solution pump, wet curtain packing and a liquid arrangement device, and meanwhile, the solution humidifying system comprises a solution filtering device and a return air energy recovery device. The wind control system mainly comprises a return air and new air blower, an air supply parameter inductor and a mechanical air exhausting system. The household type air conditioner with new air is designed by adopting a solution humidifying technology, through the air conditioner, temperature control and humidity control are conducted on the outdoor new air, temperature control is conducted on the indoor return air, then the outdoor new air and the indoor return air are sent to indoor, for the problem of lack of the new air of indoor air adjusting of a household type building in the prior art, the solution humidifying technology can be directly used for household air conditioner equipment, and the problem that water supplement is needed owing to too much heat brought by a heat pump coupling solution humidifying technology is solved.

Description

technical field [0001] The invention belongs to the technical field of heating, ventilation and air conditioning, and more specifically relates to a household air conditioner and an operating method thereof. Background technique [0002] At present, most household air conditioners in my country use indoor return air, lacking fresh air. When the air conditioning system is turned on, the pollutants accumulated in the building cannot be discharged outdoors in time, which affects indoor air quality and human physical and mental health. In addition, the traditional air-conditioning system uses condensation and dehumidification to process fresh air. Heat and humidity are processed at the same time. Usually, the temperature of the supply air is too low and reheating is required, resulting in energy waste. Moreover, simultaneous heat and humidity processing cannot achieve precise control of humidity, which reduces the Indoor air quality. [0003] With the improvement of living stan...
