Independent air-conditioning system and power supply method and application thereof

Abstract

An independent air-conditioning system comprises an engine, an electric generator, a compressor, a condenser, an expansion valve, an evaporator, a water pump and an air conditioner. The engine provides power for the compressor, one end of an engine spindle is connected with the compressor through a transmission component, the other end of the engine spindle is connected with the electric generator, the electric generator outputs electric energy to powered devices, the compressor, the condenser, the expansion valve and the evaporator are sequentially serially connected through a first pipeline to form a refrigerating circuit, and the evaporator, the water pump and the air conditioner are sequentially serially connected through a second pipeline to form a cold carrier circuit. The independent air-conditioning system can refrigerate and generate electricity, and cruising ability and drive performance of electric vehicles can be effectively improved when the system is applied to the field of the electric vehicles.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to an independent air-conditioning system and its power supply method and application. Background technique [0002] In the existing air-conditioning and refrigeration equipment, it is conventional to use household electricity to realize power conversion through the motor to supply energy to the compressor of the air conditioner. In the refrigeration equipment of the car, the car engine is used to supply energy, and the output energy of the car engine is Refrigeration equipment consumes a part, and the power output of the car is reduced, especially for cars with small displacement, if the air conditioner is turned on, it is impossible to climb up a large slope; [0003] Especially in the field of electric vehicles, the stored electric energy is limited, and the cruising range of electric vehicles is generally not as long as that of gasoline or diesel fueled vehicles.

Problems solved by technology

[0002] In the existing air-conditioning and refrigeration equipment, it is conventional to use household electricity to realize power conversion through the motor to supply energy to the compressor of the air conditioner. In the refrigeration equipment of the car, the car engine is used to supply energy, and the output energy of the car engine is Refrigeration equipment consumes a part, and the power output of the car is reduced, especially for cars with small displacement, if the air conditioner is turned on, it is impossible to climb up a large slope;

[0003] Especially in the field of electric vehicles, the stored electric energy is limited, and the cruising range of electric vehicles is generally not as long as that of gasoline or diesel fueled vehicles. At the same time, the electric energy of electric vehicles supplies power to refrigeration equipment, and the cruising range of electric vehicles is shortened.

[0004] At the same time, the existing automotive air conditioners only have refrigerant circulation, the refrigerant pipeline is long, and the refrigerant charge is large. At the same time, the refrigerant circulation pipeline is a high-pressure pipeline, the refrigerant may leak, and maintenance is inconvenient. It is necessary to carry refrigerant leak detection devices, vacuum pumps, refrigerants and other professional tools in the refrigeration industry, which makes installation difficult
