Abstract

The invention discloses a multi-temperature-zone cascade refrigeration system and a low-temperature refrigerated storage box. The multi-temperature-zone cascade refrigeration system comprises a low-temperature refrigeration system and a high-temperature refrigeration system which are connected with a condensing evaporator, wherein the outlet of a low-temperature compressor of the low-temperature refrigeration system is connected to a condensing pipe through the condensing evaporator, and then connected to evaporators in all temperature zones in a branched manner through low-temperature regulating valves; and the outlets of all the evaporators are connected to the inlet the low-temperature compressor. According to the multi-temperature-zone cascade refrigeration system, a plurality of the evaporators correspond to the different temperature zones, thereby achieving a single refrigeration system with various temperature zones and meeting the different requirements of various objects for the refrigerated storage temperature; and the high-temperature refrigeration system and the low-temperature refrigeration system are connected through the condensing evaporator, so that cold energy can be supplied by the high-temperature refrigeration system to both the objects and a low-temperature refrigerant.

Description

technical field [0001] The invention relates to the technical field of low-temperature refrigeration, in particular to a multi-temperature zone refrigeration system that can meet different temperature requirements, and a low-temperature refrigerator using the multi-temperature zone refrigeration system. Background technique [0002] The freezing and refrigeration of medical supplies, biological products, electronic materials and food is the main cooling object in the field of commercial refrigeration today. However, due to the variety of the above-mentioned items, different types of items require different refrigeration temperatures. For example, the refrigerated temperature of vaccines and common medicines is about 2°C to 8°C, the refrigerated temperature of plasma, molecular biological enzymes, and clinical samples is about -10°C to -40°C, and the refrigerated temperature of biological products and special electronic materials is about -40°C ℃~﹣60℃, the refrigerated temper...
