Abstract

The invention relates to a jet refrigeration system driven by waste heat of a refrigerated vehicle with double evaporators, comprising a waste heat recovery device, a circulation pump, a first throttling device, a second throttling device, a first evaporator, a second evaporator, a first jet device, second ejector, condenser, and gas flow control device; the first ejector and the second ejector inject refrigerants of different temperatures from the first evaporator and the second evaporator respectively; the refrigerant in the first evaporator The temperature of the refrigerant in the second evaporator can be controlled above zero, which is used for the summer cooling of the cab of the refrigerated truck; through the control of the gas flow control device, the refrigeration in the second evaporator can be changed. The temperature and flow direction of the agent can be used to realize the heating of the cab of the refrigerated truck in winter. The invention can make full use of the waste heat of the automobile to realize the whole process of refrigerating the refrigerated vehicle, and at the same time meet the air-conditioning requirements of the driver's cab, thereby broadening the application field of the jet refrigeration system.

Description

technical field [0001] The invention specifically relates to a spray refrigeration system with double evaporators driven by waste heat of a refrigerated vehicle. Background technique [0002] As people's pursuit of quality of life is getting higher and higher, the demand for fresh fruits, vegetables, meat, fish and egg milk with high nutritional value is increasing, which greatly promotes the development of refrigerated logistics. The refrigeration system of traditional refrigerated trucks operates by consuming fuel oil. The refrigeration process consumes a lot of energy, and at the same time increases the emission of vehicle exhaust and aggravates environmental pollution. Therefore, under the current situation of energy shortage and environmental pollution, it is urgent to solve the current The cooling method of refrigerated trucks has been improved. [0003] The jet refrigeration system uses low-grade heat sources such as solar energy and waste heat for refrigeration. It ...
