Abstract

This invention discloses a vapor compression type economic refrigeration system, which contains compressor, condenser, throttle and evaporator, which are jointed by welded copper pipe to form total closed refrigeration circulation system, which features membrane evaporation separator is series connected in pipeline between high pressure refrigerant outlet of condenser and high pressure refrigerant inlet of throttle, two ends of whose porous medium separation membrane connected respectively with high pressure refrigerant outlet of condenser and high pressure refrigerant inlet of throttle, refrigerant evaporation cavity connected to vapor suction open of compressor to form said closed refrigerant circulation system. Said invention raises evaporation efficiency.

Description

technical field [0001] The invention relates to a vapor compression refrigeration system, in particular to a vapor compression refrigeration system used in an air conditioner. Background technique [0002] In a vapor compression refrigeration system, the use of an economizer can significantly increase the cooling capacity and energy efficiency ratio of the system, so it is an energy-saving component that is often used. There are two types of economizers used in the past: flash drum and heat exchanger. The refrigerant circulation process of the vapor compression refrigeration system with a flash drum economizer is as follows: the high-pressure refrigerant liquid coming out of the condenser flows through the first-stage throttle valve and then enters the flash drum to generate flash vapor After the mixed liquid droplets are separated through the steel mesh separator, it enters the middle suction port of the compressor; while the refrigerant liquid flowing out of the flash cyl...
