Abstract

The invention discloses a two-way spiral flash evaporator applied to a heat pump air-conditioning system for supplementing air and increasing enthalpy. The wall is provided with an air outlet pipe, and the side wall of the lower cylinder body is provided with a first refrigerant inlet and outlet pipe and a second refrigerant inlet and outlet pipe extending to the inner cavity of the cylinder, and the first refrigerant inlet and outlet pipe and the second refrigerant inlet and outlet pipe The part where the outlet pipe is inserted into the barrel is the same clockwise or counterclockwise spiral copper tube part, and the two spiral copper tube parts are coiled and assembled to form a gas-liquid separation device. The invention solves the limitation of one-way flow of the existing flash evaporator, has two-way flow, can greatly simplify the gas supply and enthalpy increase system, and at the same time improve and ensure the gas-liquid separation effect of the flash evaporator, and is suitable for the installation height of the flash evaporator with limited height and height. Applications with small diameter ratios.

Description

technical field [0001] The invention relates to an air-conditioning system for supplementing air at low temperature to increase enthalpy, in particular to a bidirectional spiral flash evaporator applied to a heat pump air-conditioning system for supplementing air to increase enthalpy. Background technique [0002] Existing heat pump air-conditioning systems operate in a low-temperature environment, and there are still problems such as attenuation of heating capacity, reduction of heating efficiency, and unreliable system operation due to increased exhaust temperature of the compressor, which limits the popularization and use of heat pump air conditioners in cold northern regions. . Due to its good low-temperature adaptability, the air-supplementing and enthalpy-increasing heat pump air-conditioning system has been gradually applied to low-temperature household air conditioners, automobile air conditioners and other fields. [0003] In the existing air supplement enthalpy in...
