Embodiment Construction

[0016] refer to figure 1 and figure 2 , a vehicle-mounted electric drive air conditioner, including a main control circuit, an inverter drive circuit, an electromechanical integrated electric compressor, a condensation control circuit, and an evaporation control circuit; the main control circuit outputs a control signal to the inverter drive circuit, and the inverter drive circuit will The DC power supply of the car is converted into a three-phase AC power supply for the operation of the electromechanical integrated electric compressor; the low-temperature and low-pressure gaseous refrigerant from the evaporator is sucked into the compressor, and compressed by the compressor to form a high-temperature and high-pressure gas into the condenser. The high-temperature and high-pressure steam is cooled into a high-pressure liquid, and the high-pressure liquid enters the dry storage filter for dry filtration, then enters the condenser for secondary cooling, and at the same time rele...

Abstract

The invention discloses an electrically-driven vehicle-mounted air conditioner which comprises a master control circuit, an inverter drive circuit, an integrated electromechanical electric compressor, a condensation control circuit and an evaporation control circuit, wherein the master control circuit outputs a control signal to the inverter drive circuit; and the inverter drive circuit converts a direct-current power supply of a vehicle into a three-phase alternating current to be supplied to the integrated electromechanical electric compressor for running. The vehicle-mounted air conditioner has compact structure; compared with the traditional form, the weight of the whole air conditioner is decreased by more than 20 percent and the energy efficiency ratio is improved by more than 25 percent. The rotating speed of the compressor is not influenced by a running speed of a passenger vehicle, and the refrigerating effect is stable. For the passenger vehicle to which the power supply is supplied by a direct current generator, even if the generator stops to work, the air conditioner can be ensured to run about half an hour only by a pair of accumulator jars of 150A.h which supply power.

Description

technical field [0001] The invention relates to an electric-driven air conditioner for a passenger car, in particular to an air conditioner which utilizes the low-voltage direct current power supply of the vehicle itself for refrigeration. Background technique [0002] At present, the air conditioners equipped in the passenger car industry can be divided into two types: one is the traditional passenger car air conditioner used in large quantities. Connector assembly. In this way, the speed of the compressor fluctuates greatly with the change of the engine speed, especially when the air conditioner is idling, the cooling effect of the air conditioner is poor, and the air conditioner cannot be used when the engine is stopped. The other type is an electric drive air conditioner using an electric hermetic compressor, which generally adopts a fiberglass structure. The condenser is arranged in the front, the compressor is arranged in the middle, and the evaporator is arranged in ...
