Movable phase change refrigerating box capable of achieving single-area double-cold-storage mode

Abstract

The invention discloses a movable phase change refrigerating box capable of achieving a single-area double-cold-storage mode. The movable phase change refrigerating box comprises multiple stages of freezing cold storage plates and a first heat exchange tube connected with the multiple stages of freezing cold storage plates, multiple stages of refrigerating cold storage plates and a second heat exchange tube connected with the multiple stages of refrigerating cold storage plates, a first inlet joint and a first outlet joint which are connected with the first heat exchange tube, and a second inlet joint and the second outlet joint which are connected with the second heat exchange tube, wherein the first inlet joint, the first outlet joint, the second inlet joint and the second outlet joint are externally connected with a rapid cold charging device for conducting cold charging on the freezing cold storage plates and the refrigerating cold storage plates at all levels. According to the movable phase change refrigerating box, the refrigerating mode and the freezing mode can be switched in the same phase change refrigerating box according to actual needs, and the space utilization rate and flexibility of the phase change refrigerating box are improved.

Description

technical field [0001] The invention relates to a movable phase-change refrigerator, in particular to a movable phase-change refrigerator capable of realizing a single-zone double cold storage mode. Background technique [0002] my country's cold chain logistics industry started late and is still in its infancy. The circulation rate of cold chain and the utilization rate of cold chain transportation are far from those of developed countries. The circulation rate of cold chain logistics in developed countries is above 95%, while the circulation rate of domestic cold chain logistics is only about 20%. The annual loss rate of meat, fruits and vegetables in China has reached more than 20%. Traditional cold chain equipment is mainly based on mechanical refrigeration. Mechanical refrigeration has problems such as low energy utilization and environmental pollution. In addition, mechanical refrigeration has problems such as easy failure of refrigeration equipment and high operating...
