Abstract

The invention is applied to the technical field of air-conditioners, and provides an air-conditioner heat pump system, which comprises a four-way valve, a compressor connected to the first port of the four-way valve, an outdoor unit module connected in series with the second port of the four-way valve, an air-liquid separator connected to the third port of the four-way valve, an indoor unit module connected in series with the fourth port of the four-way valve, and a control system. The compressor is connected with the air-liquid separator; the outdoor unit module comprises an outdoor unit heat exchanger and an outdoor unit electronic expansion valve connected in series with the outdoor unit heat exchanger. The air-conditioner heat pump system also comprises a waste heat recovery device. When the system is in heating operation, the waste heat recovery device is connected in series between the outdoor unit electronic expansion valve and an air return port of the compressor to transfer waste heat in at least one form to a refrigerant loop of the system, and at least one kind of waste heat is recycled.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an air conditioning heat pump system. Background technique [0002] There are different energy wastes at different times in a family or in an area (for example: hotel kitchen): when cooking, the relatively low-temperature high-temperature air after heating the food will be directly discharged to the indoor environment or drawn outdoors by the range hood; When hot water is used, the used waste hot water is discharged directly to the drain. These different forms of waste energy are not fully utilized, resulting in energy waste. [0003] For the era of energy shortage, it is necessary to find a way to use these waste energy, and provide different forms of energy output according to the different needs of users in different time periods, so as to meet the needs of life, improve the quality of life, and save energy to the greatest extent. Clean and low-carbon li...
