An Adsorption and Compression Hybrid Refrigeration and Air Conditioning System Driven by Automobile Waste Heat

Abstract

The invention discloses an absorption and compression mixed refrigeration and air conditioning system driven by automobile waste heat, and belongs to the technical field of automobile air conditioning. The refrigeration and air conditioning system comprises a compressor, an evaporator, a condenser, a throttling valve, two absorption beds, two cooling water tanks, a circulation water pump, a water separation device, a water collecting device, two three-way control valve, a radiator, a thermoelectric module and a storage battery. When an air conditioner is used in an automobile, an absorption type refrigeration mode driven by waste heat of an engine always operates, if the cooling capacity is insufficient, a traditional automobile compression refrigeration mode is used for compensation, and the two refrigeration modes share one set of the condenser, the evaporator and the throttling valve. On the basis of an existing refrigeration system, few parts are additionally arranged, full recycling to the automobile waste heat is achieved, and therefore the purposes of energy saving and environmental protection are achieved. The additionally-arranged parts are free of movement parts, and the absorption and compression mixed refrigeration and air conditioning system driven by the automobile waste heat is safe and reliable and has obvious social benefits and economic benefits.

Description

Technical field [0001] The invention relates to an automobile air-conditioning refrigeration system, in particular to an automobile air-conditioning refrigeration system driven by engine and exhaust heat, belonging to the technical field of refrigeration and air-conditioning. Background technique [0002] The current automobile air-conditioning refrigeration system basically uses the traditional vapor compression refrigeration system. The compressor is driven by the automobile engine. The low-pressure gaseous refrigerant is compressed by the compressor and enters the condenser to be condensed into high-pressure liquid refrigerant, and then passes through the throttle valve. After the flow enters the evaporator to evaporate, completing a cycle. The power of this refrigeration system comes entirely from the mechanical work of the engine. The mechanical work of the engine is obtained by the expansion of fuel combustion, and the efficiency of this conversion project is usually very lo...

Problems solved by technology

However, the spray refrigeration process used by the automobile air conditioner of this invention produces large noise and low coefficient of refrigeration performance. At the same time, the automobile air conditioner refrigeration system cannot meet the needs of the automobile for air conditioning when it is parked.
