The invention discloses an outdoor gas heat pump air conditioner, which can condition air and supply hot water. Said device is formed by a left heat recycle water cycle system, a smoke-coolant heat exchange system, and a defrost system. Wherein, it comprises a gas engine, a compressor, a four-way valve, an electric expand valve, a gas engine cold water heat exchanger, a smoke heat exchanger, a gas-liquid separator, a flux adjust valve, a stop valve, and a heat exchanger. The invention can realize refrigerating, heating and hot water supply, to improve the energy utilization. In winter, the invention can continuously supply heat when defrosting, and decrease the temperature as the low-limit when heating.
Description
technical field [0001] The invention relates to a novel household gas heat pump air conditioner capable of providing domestic hot water while air conditioning, and belongs to the technical field of air conditioner manufacturing. Background technique [0002] With the widespread application of refrigeration and air-conditioning equipment and the improvement of people's living standards, the energy consumption of air-conditioning systems, indoor air quality, and air-conditioning environmental pollution have aroused widespread concern in the current society. Therefore, proposing an energy-saving, environment-friendly and comfortable refrigeration and air-conditioning method is an urgent requirement in the new situation in the refrigeration field. For conventional heat pump air conditioners, there is a defect of insufficient heating capacity in severe cold weather, and the system usually adopts a reverse defrosting method, which causes a large energy loss of the system, and the ...
