Embodiment Construction

[0027] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0028] Such as figure 1 As shown, the engine waste heat recovery vehicle-mounted air conditioning system provided by the present invention includes an engine waste heat recovery system, an engine cooling system, and a vehicle air conditioning and heating system. Wherein, the cooling circuit of the engine includes the heat transfer outlet of the internal circulation coolant of the engine 1, and the heat transfer outlet successively conducts heat transfer with the cooling valve 13, the second radiator 14, the coolant pump 12, and the internal circulation coolant of the engine 1. The inlet is connected to form a cooling loop.

[0029] The engine waste heat recovery circuit includes the heat transfer outlet of the internal circulation coolant of the engine 1, and the heat transfer outlet is sequentially connected with the coolant storage tank 4, the coolant valv...

Abstract

The invention provides an engine waste heat recovery type vehicle-mounted air conditioner system. Firstly, waste heat generated by an engine is collected and stored through a waste heat recovery and storage tank installed on the engine, and the stored waste heat is used for a vehicle-mounted air conditioner, so that heating or refrigeration can still be achieved when the engine does not work during winter heating or summer refrigeration; and meanwhile, the stored heat can be used for preheating during vehicle start-up in winter, no oil is consumed, and more energy is saved. Compared with existing novel engine waste heat recovery systems, the engine waste heat recovery type vehicle-mounted air conditioner system is advantageous in that the heat is directly stored rather than being converted into electric energy, full recovery of the heat is achieved, and energy conservation and environment friendliness are achieved.

Description

technical field [0001] The invention relates to the technical field of air conditioning systems, in particular to an engine waste heat recovery type vehicle air conditioning system. Background technique [0002] The practical efficiency of a car engine is generally 35% to 40%. Part of the unused fuel heat is taken away by the coolant, and part is taken away by the car exhaust and discharged into the atmosphere through the car exhaust device. This means that up to 70% of available energy is not used efficiently. Therefore, recovering and utilizing this part of waste heat to drive the automobile air-conditioning system is a very effective energy-saving solution. [0003] Existing automotive air-conditioning systems generally use a single-stage vapor compression refrigeration cycle. It is driven by the main engine of the car. The compressor consumes part of the power of the main engine, which will affect the acceleration performance of the vehicle, and the cooling capacity of...
