Embodiment Construction

[0023] figure 1 It is the structural principle diagram of the first embodiment of "an air treatment device with natural cooling and heating function" disclosed in the present invention. The device includes a compressor 3, a four-way valve 4, an evaporator 6, a throttling device 8, and a condenser 9. Gas-liquid separator 5; the compressor 3, four-way valve 4, evaporator 6, throttling device 8, condenser 9, and gas-liquid separator 5 are connected by pipelines to form a vapor compression heat pump circulation loop; its characteristics In that: a heat pump valve 10 is added on the connecting pipe between the normally closed port of the four-way valve 4 and the condenser 9, and the connecting pipe between the heat pump valve 10 and the condenser 9 passes through the normally closed port of the heat pipe valve 11 and the four-way valve 4. Open the port and connect; connect the valve 7 in parallel at both ends of the throttling device 8; set the high-level machine 1 and the low-leve...

Abstract

An air treatment device with natural cold and heat supply includes a compressor, a four-way valve, a gas liquid separator, a condenser, a throttling means and an evaporator. The invention is characterized in that: a heating pipe valve and a heating pump valve are added on the pipeline where the four-way valve is disposed, valves are in parallel connection with both ends of the throttling means, wherein, a high position machine and a low position machine are provided for accommodating the corresponding components. According to the invention, refrigeration and heating functions of the original system is reserved, furthermore, a heating pipe natural circulation is introduced, thereby, energy waste problem in winter and transition seasons for water circulation heating pump system building can be resolved, meanwhile, the high position energy loss during complementing heat in winter is avoided. A refrigeration agent can be additionally provided in the invention to maintain the operation performance of the heating pipe circulation, thus further increasing the energy-saving performance and the reliability of the heating pump air conditioning system. The invention is applicable for the other situations to transfer heat from the high temperature fluid end to the low temperature fluid end, and has advantages of energy-saving and reliability.

Description

technical field [0001] The invention relates to an air treatment device with natural cooling and heating functions, which is suitable for the outer area of ​​the air conditioner in the water ring heat pump air conditioning system that needs to be heated in winter and needs to be cooled in summer, and is also suitable for the inner area of ​​the air conditioner that needs to be cooled throughout the year , belonging to the field of refrigeration and air conditioning equipment. Background technique [0002] In recent years, affected by environmental pollution and energy crisis, water loop heat pump air-conditioning system, as a new type of energy-saving system, has attracted much attention in the field of air-conditioning, and has been widely used and developed rapidly. The water loop heat pump system mainly achieves energy saving through heat recovery in the inner and outer areas of the building, so this system is especially suitable for buildings with large waste heat in the...
