Abstract

The invention is applicable to the technical field of chemical equipment manufacturing, and provides a three-dimensional spiral double-effect vertical flash evaporator and a heat pump system with thesame. The flash evaporator comprises a shell, a gas outlet and a liquid outlet are formed in the two ends of the shell, the shell is connected with a gas-liquid two-phase inlet through a mounting hole, and the shell is of a three-dimensional spiral structure. The invention further provides the heat pump system with the flash evaporator. According to the flash evaporator and the system, the gas-liquid separation efficiency is high, the low liquid content of supplemented gas can be ensured along with the change of working conditions, the compression work of a compressor is saved, the efficiencyof the heat pump system is greatly improved, and the safety and the stability of the compressor are improved.

Description

technical field [0001] The invention relates to the technical field of chemical equipment manufacturing, in particular to a three-dimensional spiral double-effect vertical flash evaporator and a heat pump system with the flash evaporator. Background technique [0002] The heat pump air conditioner products with large working temperature difference that increase enthalpy with intermediate air injection have become one of the main products in the northern heat pump and southern air conditioner markets, and the main components for increasing enthalpy with intermediate air injection are divided into flash evaporators and economizers. Compared with the economizer, the flash evaporator is widely used because of its low gas supply temperature, low cost, high efficiency, and the ability to serve as a liquid storage device. [0003] The currently used flash evaporator structure mainly uses gravity and the density difference between the gas and liquid phases for separation, and the se...
