Abstract

The invention provides a cold accumulation material, which is prepared from at least one of a first group of substances, a second group of substances, a third group of substances, a fourth group of substances and a fifth group of substances, wherein the first group of substances comprise n-nonane, n-octane and hexamethyl disiloxane; the second group of substances comprise p-cymol and decamethyl tetrasiloxane; the third group of substances comprise o-cymol, vinyltoluene, ammonia and R1233ze(E); the fourth group of substances comprise 1,1,2,2,3-pentafluoropropane, 2H,3H-perfluoropentane, butylbenzene and octamethyl trisiloxane; the fifth group of substances comprise tetrafluoromonochlorethane, 1,1,1,3,3,3-hexafluoropropane, propanone, perfluoroethane and pentafluoroethane. Through the cold accumulation material, according to a different required temperature zone, the cold accumulation material which is prepared from a different monomer or a plurality of substances can be selected, can be used for meeting the demand of the temperature of subzero 60 to subzero 100 DEG C, and adapts to a plurality of scenes. In addition, the invention also provides a cold accumulator and a cold accumulation type refrigeration device.

Description

technical field [0001] The invention relates to the technical field of refrigeration and energy saving, in particular to a cold storage material, a cold storage device and a cold storage refrigeration device. Background technique [0002] In scientific research and medical fields, it is used to preserve viruses, germs, red blood cells, white blood cells, skin, bones, bacteria, semen, biological products, etc., and it is often necessary to reach a low temperature below -60°C to ensure that the cells are not destroyed. At this time, a medical ultra-low temperature refrigerator of -60°C to -100°C is needed to realize it. However, in some special cases, such as the need to transfer preserved biological materials or local power instability, etc., it is necessary to use cold storage devices to maintain a low temperature environment for a long time. In addition, in conventional low-temperature storage devices, the compressor generally runs continuously, and the shutdown frequency ...
