At the same time, we know that the quality of food has requirements on temperature. Many stores use traditional ice packs and ordinary foam insulation materials to keep the temperature low in order to maintain the quality of food. However, this kind of packaging does not last long. The process is too long and will definitely have an irreversible impact on the product
Another kind of food purchase behavior that is closely related to us is takeaway. The takeaway delivery staff has to notify the individual in detail, and then wait for the customer to come to pick up the takeaway. This process consumes a lot of time. Cool, affecting its taste

The invention discloses a twin type cold and hot express cabinet and a refrigeration and heating control method thereof. The twin type cold and hot express cabinet comprises a multi-cell hot cabinet, a control unit, a multi-cell cold cabinet and an equipment unit and particularly comprises a compressor, an electronic expansion valve, a middle heat exchanger, a hot cabinet layer unit, a heating coil pipe, a temperature control adjusting valve, a temperature sensor, a cold cabinet layer unit, a refrigeration coil pipe, an electric adjusting valve I, an electromagnetic valve I, an electric adjusting valve II, an electromagnetic valve II, a circulation pump, a stop valve and a buried pipe. Compared with an existing storage cabinet, advantages of regional heating and refrigeration at the same time are achieved, freshness keeping and heat preservation needs of stored food can be achieved, meanwhile, through the middle heat exchanger, heat need unevenness of the twin type cold and hot express cabinet in summer and winter is subject to bypass adjustment, and in cooperation with switching between serial valves, it is ensured that the temperature in the twin type cold and hot express cabinet is constant. The problem that during logistics industry distribution of existing fresh food, fast food, take-out food and the like, when a delivery man calls, people are not at home is solved.
Description
technical field [0001] The invention relates to a twin-type cold and hot express cabinet and a cooling and heating control method thereof, belonging to the field of express cabinets.
