Multi-temperature-zone refrigeration system with vortex tube

Abstract

The invention discloses a multi-temperature-zone refrigeration system with a vortex tube. A compressor is connected with a first condenser, the first condenser is connected with a gas-liquid separation device, a gas outlet of the gas-liquid separation device is connected with the vortex tube, and a hot end outlet of the vortex tube is sequentially connected in series with a second condenser, a first expansion valve, a first evaporator and a first pressure reducing valve; a cold end outlet of the vortex tube is sequentially connected in series with a second expansion valve and a second evaporator, and the outside of the second expansion valve is parallel to a first bypass valve; a liquid outlet of the gas-liquid separation device is sequentially connected in series with a third expansion valve, a third evaporator and a second pressure reducing valve; an outlet of the first pressure reducing valve, an outlet of the second evaporator and an outlet of the second pressure reducing valve are connected with the compressor after being connected into a circuit. By using the multi-temperature-zone refrigeration system with the vortex tube, the problem that different refrigeration devices are needed for different refrigeration temperatures and storage environments in some occasions such as hypermarkets and the like is solved. Multi-temperature-zone refrigeration is realized by adopting aset of refrigeration system and device through an energy separation effect of the vortex tube, and the system efficiency is increased by utilizing generated heat quantity.

Description

technical field [0001] The invention belongs to the field of refrigeration systems, in particular to a refrigeration system with vortex tubes capable of realizing refrigeration regulation in multiple temperature zones. Background technique [0002] In many fields, the requirements for product freezing, refrigeration, and cold freshness are getting higher and higher, especially in the fields of food, biology, and medicine, which have high requirements for the storage environment. In these occasions, different product types have different requirements for the storage environment temperature, which is a challenge for the refrigeration system and its adjustment and maintenance. For example, in large supermarkets, there are generally special areas for consumers to buy cold fresh meat, seafood, dairy products, vegetables, etc. The storage temperature and environmental requirements of these products vary greatly. Supermarkets often need to purchase a variety of cold drink cabinets....
