Abstract

The invention discloses a refrigerating or heat pump system with jetting gas-liquid separation heat exchange. The refrigerating or heat pump system comprises a compressor, a condenser, an ejector, a heat regenerator, a throttling element and an evaporator; the compressor, the condenser, the heat regenerator, the throttling element and the evaporator are sequentially connected to form a heat exchange loop; a condensate collecting tank is arranged at the bottom of a single condensing pipeline above the condenser; a liquid extracting pipe is connected to the condensate collecting tank; a gas-phase working medium collecting tank is arranged at the top of a single evaporation tube pass below the evaporator; the gas-phase working medium collecting tank is connected with an air suction pipe; theliquid pumping pipe is connected with a working fluid inlet of the ejector; the air suction pipe is connected with the air inlet of the ejector; and the working fluid outlet of the ejector is connected with the air supply port of the compressor through the heat regenerator. According to the system, a saturated working medium is extracted, so that components of the working medium in the thermodynamic cycle are adjusted, and thus the heat exchange capacity of the condenser and the evaporator is improved, and the problems that an existing refrigeration or heat pump system is low in efficiency andhigh in energy consumption are solved.

Description

technical field [0001] The present application relates to the technical field of heat exchange, and in particular to a refrigeration or heat pump system with injection gas-liquid separation heat exchange. Background technique [0002] Heat exchange technology is becoming more and more mature. The working principle of heat pump and refrigeration system is the same. Taking refrigeration system as an example, it generally consists of four parts: compressor, condenser, throttling element, and evaporator. Its working process is: low-temperature and low-pressure liquid refrigerant (such as Freon), first absorbs heat from a high-temperature heat source (such as normal-temperature air) in an evaporator (such as an air-conditioning indoor unit) and vaporizes into low-pressure steam. Then the refrigerant gas is compressed into a high-temperature and high-pressure vapor in the compressor, and the high-temperature and high-pressure gas is cooled and condensed into a high-pressure liquid...
