Abstract

The invention discloses a tail gas waste heat driving injection refrigeration system for a vehicle air conditioner for replacing a traditional steam compression refrigeration system for the vehicle air conditioner. The system consists of a tail gas heat exchanger, a generator, a main injector, an auxiliary injector, an evaporator, a condenser, a flash tank, an expansion valve, an electric three-way adjusting valve and an electromagnetic valve. The system has the following advantages: (1) the traditional steam compression refrigeration system for the vehicle air conditioner is replaced; and the performance reduction and the energy consumption rise of an engine caused by driving of a compressor are prevented; (2) the vehicle tail gas waste heat is reasonably used, and the exhaust temperature of tail gas is reduced, so that the activity of a catalyst in a catalytic converter is improved, and the environmental heat pollution and the harmful gas emission are reduced; (3) the system has no moving parts, needs no lubricating oil, is simple, and is reliable in work; and (4) the system uses water as a refrigerant, and totally has no harm to human bodies and environments.

Description

technical field [0001] The invention belongs to the field of refrigeration technology and the field of energy-saving technology of auto parts, in particular to an exhaust waste heat-driven injection refrigeration system used for automobile air conditioners. Background technique [0002] With the development of the automobile industry and the gradual advancement of energy-saving and emission-reduction goals, higher requirements have been put forward for the refrigeration system of automobile air conditioners. The operation of the currently dominant vapor compression automotive air-conditioning system is that the compressor is directly driven by the engine through a belt, which consumes a certain amount of shaft work, thereby increasing the engine load and reducing efficiency; moreover, the automotive air-conditioning compressor has many moving parts. , the structure is complex, and it needs a set of auxiliary systems such as lubricating oil system and electromagnetic clutch, ...
