Capillary tube radiation and fresh air dehumidifier combined operation heat pump system

Abstract

The invention discloses a capillary tube radiation and fresh air dehumidifier combined operation heat pump system which comprises a refrigerating system and a radiation water circulation system; the refrigerating system comprises a compressor, a four-way reversing valve, a heat exchanger a, a gas-liquid separator, a heat exchanger b, a one-way valve b, a second thermal expansion valve, a heat exchanger c, a one-way valve a, a first thermal expansion valve, a heat exchanger d, a one-way valve d and a one-way valve e; an exhaust port and an air suction port of the compressor communicate with a port D and a port S of the four-way reversing valve correspondingly, a port C of the four-way reversing valve is connected with the input end of the heat exchanger a, and the output end of the heat exchanger a is connected with two refrigerant pipelines through the gas-liquid separator; and the first refrigerant pipeline comprises the one-way valve a, the first thermal expansion valve and the one-way valve d which are communicated in sequence. Compared with the prior art, a single-stage steam compression and two-stage throttling mode is adopted, and the cooling and dehumidification functions on fresh air and the refrigerating and heating functions of a radiation water circulation system are achieved.

Description

【Technical field】 [0001] The patent of the present invention relates to a capillary tube heat pump system, in particular to a capillary tube radiation and fresh air dehumidifier combined operation heat pump system. 【Background technique】 [0002] In recent years, the air-conditioning system with independent temperature and humidity control has attracted the attention of many researchers with its brand-new ideas and reasonable energy utilization methods, and has set off a research boom in the industry. The air-conditioning system with independent control of temperature and humidity uses two independent air-conditioning control systems for temperature and humidity to control and adjust the indoor temperature and humidity respectively, thereby avoiding the energy loss and loss caused by the combined treatment of temperature and humidity in conventional air-conditioning systems. discomfort. As one of the air-conditioning systems with independent temperature and humidity control...
