Abstract

The invention discloses a residual heat supercooling-based CO2 automobile air conditioner system which comprises a compressor, an evaporator, a gas cooler, a throttle valve, a thermoelectric power generator, a thermoelectric subcooler, a thermoelectric power generator and an engine; an outlet of the evaporator is connected with an inlet of the compressor; an outlet of the compressor is connected with an inlet of the gas cooler; an outlet of the gas cooler is connected with an inlet of the thermoelectric subcooler; an outlet of the thermoelectric subcooler is connected with an inlet of the throttle valve; an outlet of the throttle valve is connected with an inlet of the evaporator; an outlet of an engine gas pipe is connected with the thermoelectric power generator; and a power manager is connected with the thermoelectric subcooler and the thermoelectric power generator respectively. The residual heat supercooling-based CO2 automobile air conditioner system utilizes a temperature difference between high-temperature tail gas and environment air to output electric energy for driving the thermoelectric subcooler, so that the energy utilization ratio is increased.

Description

technical field [0001] The present invention relates to semiconductor refrigeration technology and CO 2 Refrigeration cycle field, especially related to a CO based on waste heat subcooling 2 Car air conditioning system. Background technique [0002] With the development of contemporary society and the improvement of people's living standards, the number of family cars is increasing day by day. Vehicle exhaust emissions are also increasing. Carbon monoxide, carbon dioxide, and nitrogen oxides in automobile exhaust cause great damage to the environment, produce a greenhouse effect, and destroy the ozone layer. In addition, the temperature of the exhaust gas emitted by the automobile engine is as high as 600-700°C, and 30% to 45% of the energy in the engine fuel is discharged into the atmosphere along with the exhaust gas, resulting in a waste of energy. Therefore, the recovery and utilization of waste heat from automobile exhaust has greatly improved the utilization of ene...
