Food frozen and refrigerated transport vehicles are the most important part of the food refrigerated transport chain. The temperature in the frozen and refrigerated car compartments is +5 °C to minus 18 °C. The general refrigerator components are independent and non-independent. The non-independent refrigeration unit is driven by the main engine of the vehicle, and the freestanding refrigeration unit is driven by an independent gasoline engine. Whether it is a gasoline engine or a skimmer, it consumes gasoline or slag, consumes a lot of fuel, and has high transportation costs and pollutes the environment.

In order to reduce transportation costs and reduce pollution, some refrigerated and refrigerated vehicles are equipped with electric motors to solve the problem of cooling during parking and stoppage. However, when the car is driving, it still needs a gasoline engine or a skimmer to drive the refrigeration unit to cool. Our energy-saving and environmentally-friendly storage and refrigeration vehicles are mainly powered by electricity. At night and during the day and during dinner, the power consumption is not large. The refrigeration unit uses the power cooling and cold storage during this period to make full use of the low price in the valley. Electricity, compared with cars that require engine power cooling, can save 40-50% of oil, reduce transportation costs, and reduce emissions, which is good for the environment. Where there is a power source, it can be cooled and replenished. No fuel, no carbon pollution.

In our proposal, we have proposed a new type of energy-saving and environmentally-friendly storage-type frozen and refrigerated vehicles that use valley power refrigeration and cold storage, representing a new peak in the development of refrigeration and refrigeration vehicles. [utility content]
