Problems solved by technology

[0002] Under the premise of the current vigorous promotion of new energy urban trucks, urban pure electric refrigerated vehicles have also been widely used. The market mainly uses three kinds of power supply DC600V, AC220V and AC380V. The compatibility of the power supply mode of the refrigerating unit is also particularly important. For the use of multiple power sources, the cost of the on-board power supply is also very large

Abstract

The invention relates to a double-electric-mode pure electric freezing and refrigerating unit. The double-electric-mode pure electric freezing and refrigerating unit comprises a condenser assembly, acontrol drive assembly and an evaporator assembly, wherein the control drive assembly comprises a drive control assembly shell, a control module, a transformer, a rectifier, a frequency converter anda compressor, the controller is electrically connected with the transformer, the rectifier and the frequency converter, the transformer is further connected with the rectifier to convert the input power supply mode, and the frequency converter is connected to the compressor; and the control driving assembly, the condenser assembly and the evaporator assembly are sequentially connected in series toform a loop so as to form a closed system of a refrigeration cycle. According to the double-electric-mode pure electric freezing and refrigerating unit, the two power modes of the freezing and refrigerating unit can be switched according to the actual working conditions of a pure electric refrigerator vehicle; and meanwhile, the integral refrigeration circulation loop is arranged, so that the refrigeration efficiency is effectively improved, and the loss of a vehicle-mounted power supply is reduced.

Description

technical field [0001] The invention relates to the technical field of refrigerating equipment, in particular to a dual-electric mode pure electric refrigerating and refrigerating unit. Background technique [0002] Under the premise of the current vigorous promotion of new energy urban trucks, urban pure electric refrigerated vehicles have also been widely used. The market mainly uses three kinds of power supply DC600V, AC220V and AC380V. The compatibility of the power supply mode of the refrigerating unit is also particularly important. For the use of multiple power sources, the cost of the vehicle power supply is also very large. [0003] Based on this, it is necessary to design a dual-electric mode pure electric refrigerating unit. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art and obtain a dual-electric mode pure electric refrigerating and refrigerating unit, so as to improve the refrigerating ...
