Abstract

The invention discloses a bi-directional spiral flash vessel applied to an air-supplementing and enthalpy-increasing heat pump air-conditioning system. The flash vessel comprises a barrel body, the barrel body comprises an upper-segment barrel body, an intermediate-segment barrel body and a lower-segment barrel body from top to bottom, an air outlet pipe is arranged on the side wall of the upper-segment barrel body, a first cooling agent inlet and outlet pipe and a second cooling agent inlet and outlet pipe which extend to an inner cavity of the barrel body are arranged on the side wall of the lower-segment barrel body, the portions, inserted into the barrel body, of the first cooling agent inlet and outlet pipe and the second cooling agent inlet and outlet pipe are spiral copper pipe portions both of which spirally extend upward clockwise or anticlockwise, and the two spiral copper pipe portions are assembled in a coiled mode so as to jointly form a gas-liquid separation device. By means of the bi-directional spiral flash vessel, the limit of unidirectional flow of an existing flash vessel is broken through, the bi-directional flowability is achieved, the air-supplementing and enthalpy-increasing system can be greatly simplified, meanwhile, the gas-liquid separation effect of the flash vessel is guaranteed and improved, and the bi-directional spiral flash vessel is applicable to an application occasion where the installation height of the flash vessel is limited and the specific value between the height and the diameter is small.

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...
