Refrigerator system using tiny moving-magnetic type series-connection double-stage linear compressor

Abstract

The invention provides a refrigerator system using a tiny moving-magnetic type series-connection double-stage linear compressor. The refrigerator system comprises the moving-magnetic type series-connection double-stage linear compressor, a cold storing and refrigerating system and a freezing and refrigerating system. The cold storing and refrigerating system comprises a compressor, a condenser, a dry filter, an electromagnetic valve 1, a cold storing chamber capillary pipe, a cold storing chamber evaporator and a liquid storing device 1. The freezing and refrigerating system comprises a compressor, a condenser, a dry filter, an electromagnetic valve 2, a freezing chamber capillary pipe, a freezing chamber evaporator and a liquid storing device 2. The refrigerator system adopts the tiny moving-magnetic type series-connection double-stage linear compressor, and is compact in structure, small in size, free of oil lubrication and high in efficiency. The refrigerator system has three operation modes which comprise a single cold storage operation mode, a single freezing operation mode and a cold storing and freezing simultaneous operation mode. According to the refrigerator system, by the adoption of the series-connection double-stage linear compressor, the pressure ratio can be increased effectively, and lower temperature can be obtained.

Description

technical field [0001] The invention relates to the field of refrigeration, in particular to a refrigerator system using a miniature moving magnet type series-connected two-stage linear compressor. Background technique [0002] With the improvement of people's living standards, people have higher requirements for the freezing of some foods. The freezing function temperature of conventional refrigerators is generally higher than -18°C, but some seafood needs to be preserved better below -40°C. Taking meat products as an example, when stored in an ordinary refrigerator, the refrigerated temperature should not exceed 2 days at 7°C, the refrigerated temperature should not exceed 5 days at 0°C, and the freezing time at -18°C should not exceed 1 month. . For foods that need to be stored for a long time, the lower the freezing temperature, the more the growth and reproduction of microorganisms and the activity of enzymes can be inhibited, the smaller the loss of nutrients, and th...
