Refrigeration system and new-energy refrigerator car

Abstract

The invention provides a refrigeration system. The refrigeration system comprises a compressor, a condensing component, a cold accumulation box and an expansion valve; the compressor communicates withthe fluid of the cold accumulation box in order as to compress low-temperature low-pressure refrigerant gas stored inside the cold accumulation box into high-temperature high-pressure refrigerant gas; the condensing component communicates with the fluid of the cold accumulation box in order to condense the high-temperature high-pressure refrigerant gas into high-pressure intermediate-temperaturerefrigerant liquid; the expansion valve communicates with the fluid of the condensing component in order to realize pressure reduction and throttling of the high-pressure intermediate-temperature refrigerant liquid and return the pressure-reduced and throttled high-pressure intermediate-temperature refrigerant liquid to the cold accumulation box; the low-pressure intermediate-temperature refrigerant liquid is expanded and evaporated in the cold accumulation box to form low-temperature low-pressure refrigerant gas; the low-temperature low-pressure refrigerant gas exchanges heat with the cold accumulating liquid in the cold accumulation box so as to store the cold quantity; and the cold accumulating liquid exchanges heat with air of the external environment to reduce the environmental temperature. The invention further relates to a new-energy refrigerator car comprising the refrigeration system.

Description

technical field [0001] The invention relates to the field of transportation, more specifically, to a refrigeration system and a new energy refrigerated vehicle including the refrigeration system. Background technique [0002] With the rapid development of the world economy and the emphasis on environmental awareness, energy-saving, safe, and pollution-free new energy vehicles are the future development trend. As the quality requirements for food and medicine continue to increase, it is particularly important to ensure their freshness and safety during transportation. Therefore, new energy refrigerated vehicles came into being. [0003] However, the existing new energy refrigerated vehicles either install the engine to drive the compressor refrigeration system, and cool down the refrigerated compartment of the new energy refrigerated vehicle through the evaporator in the compressor refrigeration system; or use the cold storage type insulation refrigerated compartment.

Problems solved by technology

However, these two methods will either cause the load of the new energy refrigerated truck to be overloaded and the battery life will be short, or the heat preservation time will be short, and the heat preservation effect and transportation time will be limited.
