Abstract

The invention discloses a refrigerator car refrigerating system based on engine waste heat recycling. The refrigerator car refrigerating system based on engine waste heat recycling is composed of an engine waste heat temperature differential power generation system and a CO2 refrigerating system; the engine waste heat power generation system comprises an internal combustion engine, an exhaust pipe, a temperature differential power generation module, a storage battery set and a storage battery management control system which are sequentially connected, and the CO2 refrigerating system comprises a compressor, a gas cooler, a temperature differential refrigerating module, a throttling valve and an evaporator which are sequentially connected; and a compressor gas outlet is connected with a gas cooler gas inlet, an evaporator gas outlet is connected with a compressor gas inlet, and the storage battery set is connected with the temperature differential refrigerating module. According to the refrigerator car refrigerating system based on engine waste heat recycling, waste heat of tail gas of the internal combustion engine is recovered through the temperature differential power generation module and converted to electric energy, and the part of electric energy is used by the temperature differential refrigerating module to further cool a refrigerant at a gas cooler outlet; and the refrigerating capacity is increased, the property of the refrigerating system is promoted, oil consumption for driving the compressor is reduced, overall energy efficiency of a refrigerator car is promoted, and carbon emission is reduced.

Description

technical field [0001] The invention relates to engine waste heat recovery and utilization technology, environment-friendly refrigerant technology, and the field of refrigeration and air conditioning, in particular to an energy-saving and environment-friendly refrigerating vehicle refrigeration system based on engine waste heat utilization.
