Problems solved by technology

[0003] Although the air source heat pump utilizes the low-grade heat energy of the outside air, it still has certain defects. The performance of the air source heat pump is greatly affected by the change of outdoor air temperature and humidity; if the outdoor air temperature is too low or the humidity is too high, it will cause the air source heat pump Frosting occurs on the outdoor evaporator in winter, which reduces its heat transfer performance

Abstract

The invention discloses a heat pump air conditioning system provided with a flat tube plate-fin type heat-source tower and a working method of the system. The system comprises the oval flat tube plate-fin type heat-source tower, an air conditioner, a first water pump, an evaporator, a reversing valve, a first check valve, a second water pump and a second check valve; the oval flat tube plate-fin type heat-source tower comprises a tower body, and a spraying device, an oval flat tube plate-fin type heat exchanger and a solution tank are sequentially arranged in the tower body from top to bottomsequentially. According to the air conditioning system and the working method thereof, the heat exchange performance is excellent both in winter and summer and frosting of the evaporator is avoided.

Description

technical field [0001] The invention relates to an air conditioning system and its working method, in particular to a flat tube plate-fin heat source tower heat pump air conditioning system and its working method. Background technique [0002] At present, the air source heat pump air conditioning system is one of the main heat pump system forms. It is composed of evaporator, compressor, expansion valve, condenser and terminal device. During cooling in summer, high-temperature and high-pressure refrigerant steam enters the condenser to exchange heat with cooling water, and the refrigerant steam after heat release condenses into high-temperature and high-pressure refrigerant liquid, which becomes low-temperature and low-pressure refrigerant liquid after passing through the throttling expansion valve and enters evaporation After absorbing the temperature of the chilled water, it evaporates into a low-temperature and low-pressure refrigerant vapor, then enters the compressor to...
