Middle and low temperature integrated type refrigerated storage / refrigerating system

Abstract

The invention relates to a moderate-and-low temperature integrated cold storage / refrigeration system used for providing the cold storage moderate temperature for preserving food and the like or providing the refrigeration low temperature for preserving drinks and the like in supermarket and convenience store. The system comprises an integrated unit, a moderate temperature cold cupboard, a low temperature refrigeration cupboard and a corresponding connection pipeline; the integrated unit also comprises a public condenser used for condensing a high-temperature and high-pressure gaseous refrigerant in the moderate temperature cold storage system and the low temperature refrigeration system, a public liquid receiver used for storing a high-temperature and high-pressure liquid refrigerant in the moderate temperature cold storage system and the low temperature refrigeration system, a supercooling degree regulating mechanism used for regulating the supercooling degree in the low temperature refrigeration system, and a suction temperature regulating mechanism used for regulating the suction temperature in the low temperature refrigeration system. The moderate-and-low temperature integrated cold storage / refrigeration system has compact structure, convenient installation, better refrigeration performance and higher stability.

Description

【Technical field】 [0001] The invention relates to a medium-low temperature integrated refrigeration / freezing system, in particular to an integrated system for providing medium-temperature refrigeration and low-temperature freezing for food and cold drinks in supermarkets and convenience stores. 【Background technique】 [0002] In real life, supermarkets or convenience stores provide a variety of refrigerated display cabinets, which are used to provide a refrigerated environment for keeping food, beverages, cold drinks, etc. fresh and refrigerated when the external temperature is high. Usually different products require different temperatures for freezing and keeping fresh. In general, people divide the freezing system into a low-temperature freezing system and a medium-temperature refrigeration system. The cryogenic refrigeration system usually provides a freezing temperature of minus 30 degrees Celsius, and is mainly used for products that need to be frozen near minus 30 deg...

AI Technical Summary

Problems solved by technology

However, since this method adopts two independent systems, supermarkets and convenience stores usually need to provide machine rooms for placing the compressors and condensers of the two systems, which not only wastes the space of supermarkets and convenience stores, but also increases on-site installation complexity

At the same time, the two independent systems reuse condensers, liquid storage equipment, etc., which wastes raw materials and increases the hardware cost of the system, which is not conducive to energy saving and product cost reduction
