Abstract

The invention is applicable to the technical field of chemical equipment manufacturing, and provides a two-way variable-space spiral vertical flash evaporator. The two-way variable-space spiral vertical flash evaporator comprises an upper shell and a lower shell which are hermetically connected; the upper shell is of a three-dimensional spiral structure, and a gas outlet is formed in the top of the upper shell; a gas-liquid two-phase inlet and a liquid outlet are formed in the bottom of the lower shell; a baffle is further arranged in the lower shell; the baffle is arranged between the gas-liquid two-phase inlet and the liquid outlet; and a plurality of liquid-equalizing oil return holes are formed in the baffle. The invention also provides a heat pump system with the flash evaporator. Therefore, the two-way variable-space spiral vertical flash evaporator can achieve the air-liquid efficient separation, and also can achieve the functions of two-way oil return and uniform liquid, improves the safety and stability of a compressor, and provides a solution for the integrated subtractive design of the two-way operation of an air-jet enthalpy-increasing heat pump air-conditioning systemof the flash evaporator.

Description

technical field [0001] The invention relates to the technical field of chemical equipment manufacturing, in particular to a two-way variable space spiral vertical flash evaporator and a heat pump system with the flash evaporator. Background technique [0002] At present, the small heat pump air-conditioning products have two functions of heating and cooling, and the switching of its functions is realized by the four-way reversing valve connected to the exhaust port of the compressor. Moreover, the intermediate jet enthalpy increasing technology applied in severe cold regions and hot summer regions has been proved to have obvious effects of strengthening output load, improving working conditions and increasing COP value under the condition of large working temperature difference. The flash evaporator is the main part of the intermediate gas injection enthalpy increase, and its gas-liquid separation efficiency and reliability are the main factors affecting the performance of t...
