摘　　要：随着食品安全问题频发，大多问题源于食品保存不当造成。目前食品保存主要分高温保鲜，低温冷藏。其中低温冷藏我们通常采用先速冻冻结后，再低温冷藏，一般速冻温度范围在．35度左右，而对于．35度的温度单级制冷压缩机机由于压缩比过大无法保证压缩机寿命，虽然双级制冷压缩机比单级制冷压缩机更有优势，但由于其在高温段又存在不足，高温时降温速度慢，从而应运而生的单机单、双级切换制冷压缩机完美结合了二者的优势。它以独特的优越性将逐渐占据速冻冷藏行业。With frequent food safety problems, the most problem is the result of improper food preservation. The main points of high temperature preservation food preservation, low temperature cold storage. Which we usually adopt deep freeze first quick-frozen after freezing, and low temperature cold storage, frozen temperature range in - 35 degrees or so commonly, for - 35 degrees the temperature of the single stage compressor refrigeration compression machine machine due to the large compression ratio cannot be guaranteed life, although the double-stage refrigeration compressor has much more advantages than single stage compressor, but because of its disadvantages, the high temperature, and high temperature cooling speed is slow, thus arises at the historic moment of the single sheet, the double-stage refrigeration compressor switch perfectly combines the advantages of both. It will gradually occupy the advantages of quick-frozen refrigeration industry.
