Problems solved by technology

[0002] As we all know, in the existing water heater system and air conditioning system, due to the harsh external environment, frost usually forms on the evaporator during heating operation, resulting in low heat exchange efficiency
Usually, the defrost mode is set to defrost the frost layer on the evaporator. When defrosting, the four-way valve reversing method is usually used. Due to the four-way valve reversing, the system will run in refrigeration and affect the condenser. heat transfer effect

Abstract

The invention discloses a heat exchanging device. The heat exchanging device comprises a compressor, a gas-liquid separator, a first proportional adjusting valve, a condenser, a four-way valve, an electronic expansion valve, an evaporator and a liquid storage tank. An exhaust pipe of the compressor is connected with an inlet of the first proportional adjusting valve through the gas-liquid separator. A first outlet of the first proportional adjusting valve is connected with a refrigerant inlet end of the condenser. A second outlet of the first proportional adjusting valve is connected with a refrigerant outlet end of the condenser. The four-way valve is provided with an exhaust end, a gas returning end, a condenser end and an evaporator end. The exhaust end is connected with the refrigerant outlet end of the condenser. The condenser end is connected with a refrigerant inlet end of the evaporator. The evaporator end is connected with a refrigerant outlet end of the evaporator. The gas returning end is connected with a gas returning pipe of the compressor through the liquid storage tank. According to the heat exchanging device, heating and defrosting are carried out at the same time.

Description

technical field [0001] The invention relates to the technical field of heating, in particular to heat exchange equipment. Background technique [0002] As we all know, in the existing water heater system and air conditioning system, due to the harsh external environment, frost usually forms on the evaporator during heating operation, resulting in low heat exchange energy efficiency. Usually, the defrost mode is set to defrost the frost layer on the evaporator. When defrosting, the four-way valve reversing method is usually used. Due to the four-way valve reversing, the system will run in refrigeration and affect the condenser. heat transfer effect. [0003] The above content is only used to assist in understanding the technical solution of the present invention, and does not mean that the above content is admitted as prior art. Contents of the invention [0004] The main purpose of the present invention is to provide a heat exchange device, aiming at defrosting while hea...
