The invention relates to the technical field of display cabinets, in particular to a selling scene adaptive constant-temperature
display cabinet capable of switching a cold and heat combined supply mode, which comprises a cabinet body
assembly, a refrigerating and
heating system and a control module, the cabinet body
assembly comprises two independent heat preservation cabinet bodies which are the first cabinet body and the second cabinet body respectively. The refrigerating and
heating system comprises a compressor, a four-way
reversing valve, an external
heat exchanger, two internal heat exchangers, three electromagnetic valves, two capillary tubes and an
electric heating wire. According to the selling scene adaptive constant-temperature
display cabinet capable of switching the cold and heat combined supply mode, the problem that equipment is idle can be solved, the
utilization rate is increased, through flexible switching of the total cold mode, the total heat mode and the cold and heat combined supply mode, the
display cabinet is adaptive to different seasons in winter, summer, spring and autumn and different selling scenes such as scenic spots and convenience stores, one device can replace a traditional independent cold and heat insulation cabinet, and the cost is reduced. Out-of-season equipment idling is thoroughly avoided, frequent equipment replacement is not needed, the equipment moving frequency is reduced, and the damage risk in the carrying process is reduced.
