According to the scope of application, it can be divided into low back pressure type, medium back pressure type and high back pressure type. Low back pressure type (evaporation temperature -35 ~- 15℃), generally used in household refrigerators, food freezers, etc. Medium back pressure type (evaporation temperature -20 ~ 0℃), generally used in cold drink cabinets, milk freezers, etc.
