Example Embodiment

[0019] The specific content of the dual-energy refrigeration and air-conditioning with solar energy and engine waste heat for the automobile will be introduced in detail below according to the attached drawings.

[0020] Such as figure 1 with 2 As shown, the car air conditioner includes an absorber 12, a solution pump 13, a low temperature heat exchanger 8, a high temperature heat exchanger 9, a high pressure generator 10, a low pressure generator 11, a condenser 16, an air-cooled radiator 17, and an evaporator 15. And the refrigerant pump 14, which is the refrigeration part of the air conditioner. It uses water as the refrigerant and lithium bromide solution as the absorbent for refrigeration. Absorber 12, evaporator 15 and condenser 16 (in figure 2 A large circle is added to the periphery of them) is installed in a vacuum chamber to maintain a low pressure to ensure the smooth progress of the lithium bromide refrigeration process.

[0021] The car air conditioner also includes ...

Abstract

The invention relates to an automotive solar energy and engine waste heat dual-energy refrigeration air conditioner, in particular to an air conditioner device by comprehensively using solar energy and automotive engine waste heat. The air conditioner comprises an absorber, a solution pump, a low-temperature heat exchanger, a high-temperature heat exchanger, a high-pressure generator, a low-pressure generator, a condenser, an evaporator, a refrigerant pump and an air-cooling radiator, and is characterized by also comprising an interior heat exchanger connected with a heat exchange coil arranged in the evaporator, a heat energy storage which is connected and exchanges heat with the high-pressure generator through a heat-transfer pipe and a heat pump arranged in the heat-transfer pipe. Solar energy collected by a solar energy thermal collector arranged on the top of an automobile and engine waste heat collected from engine exhaust pipe and engine radiation water tank input heat into the inside of the heat energy storage through pipelines. The refrigeration part of the air conditioner uses water as a refrigerant and a solution of lithium bromide as an absorbent for refrigeration. The air conditioner reasonably uses solar energy and engine waste heat in automotive air conditioner, and is characterized by economy, energy conservation, no environmental pollution and the like.

Description

Technical field [0001] The invention belongs to a vehicle air conditioner, in particular to a refrigeration and air conditioner which comprehensively utilizes solar energy and waste heat of a vehicle engine. Background technique [0002] With the rapid development of my country's automobile industry, the connection between automobiles and people's lives is getting closer and closer. As a result, the demand for petroleum energy is also increasing, and the impact on the ecological environment is also increasing. For example, in summer, more than 20% more fuel is consumed when the air conditioner is turned on. As the temperature rises, many car owners feel that the gasoline cost of the air conditioner increases linearly; The heat island effect; as cities get hotter, more energy will be consumed to cool the interior of buildings. [0003] When driving a car, the heat generated by the engine is enough to destroy the car itself. If overheating is more harmful, it will affect the ...
