Problems solved by technology

[0003] The existing refrigerant circulation circuit only has the function of an expansion circuit. When the refrigerant circulation circuit is used to dehumidify the cold air, it will cause the indoor temperature to fluctuate, which will cause discomfort to the people in the room.
In addition, when the refrigerant circulation circuit is used for heating defrosting, it will cause insufficient heating temperature and incomplete defrosting

Abstract

An apparatus with dehumidification and defrosting abilities comprises a compressor, an indoor heat exchanger, an outdoor heat exchanger, a four-way valve and a means for refrigerant flow controlling. The compressor is coupled to the four-way valve. The four-way valve is coupled to the outdoor heat exchanger. The indoor heat exchanger is coupled to the four-way valve. The means for refrigerant flow controlling is respectively coupled to the indoor heat exchanger, the outdoor heat exchanger and the four way valve, to control mixing a low-temperature refrigerant and a high-temperature before flowing into the indoor heat exchanger, or to control mixing a low-temperature refrigerant and a high-temperature refrigerant before flowing into the compressor, or control mixing a low-temperature refrigerant and a high-temperature refrigerant before flowing into the outdoor heat exchanger.

Description

technical field [0001] A device with dehumidification and defrosting functions and its control method, especially a device capable of dehumidification without heating up or defrosting without cooling down and its control method. Background technique [0002] Air-conditioning systems are widely used in people's daily life. Existing air-conditioning systems can roughly provide functions such as cooling, dehumidification, defrosting, and heating. These functions are achieved by using a refrigerant circulation loop. [0003] The existing refrigerant circulation circuit only has the function of an expansion circuit. When the refrigerant circulation circuit is used to dehumidify the cold air, it will cause the indoor temperature to fluctuate, which will cause discomfort to people in the room. In addition, when the refrigerant circulation loop is used to defrost the heating, it will cause insufficient heating temperature and incomplete defrosting. [0004] As mentioned above, how ...
