Embodiment Construction

[0010] Depend on figure 1 Known, the vehicle cooling and heating air exchange system driven by high-energy-efficiency motors includes an evaporator 2, a condenser 9, an electric compressor 11, a four-way reversing valve 12 and a dry liquid storage tank 30; they are connected by a pipeline 15 It forms a closed system and is set in a box. The four-way reversing valve 12 is controlled by the electronic control system. One end is respectively connected with the inlet and outlet of the four-way reversing valve 12, and the other inlet and outlet is connected with the dry liquid storage tank 30 through a one-way valve to realize the conversion of cooling and heating of the system. It is characterized in that: the refrigeration is a refrigerant After being vaporized in the evaporator 2, it enters the electric compressor 11. The numerical control panel 29 of the electronic control system calculates the temperature and pressure parameters measured by each sensor, and instructs the compr...

Abstract

A cold-warm air exchange system based on high-efficiency motor driving for an automobile comprises an electric compressor, a condenser, a condensing blower, an expansion valve, an evaporator, an evaporator blower as well as an electronic control system, which are connected with one another by pipelines to form a closed system, and is characterized in that after finishing the heat exchange with air inside a carriage, a refrigerant in the evaporator is gasified to low-temperature and low-pressure steam to firstly enter the electric compressor and then enter the evaporator to absorb heat quantity of objects around the evaporator so as to enable the temperature of the evaporator to be lowered, and used for completing the refrigeration cycle in cycles. According to the invention, the condenser and the evaporator are used as heat exchange equipment of the system, and used for outputting the heat quantity from the system and inputting the heat quantity to the system. The electronic control system is used for calculating based on parameters (temperature, pressure, and the like) of all sensors by a mathematical model and empirical data to precisely control the rotation speed of the electric compressor, the opening degree of an electronic expansion valve and reasonable wind amount of the blowers so as to enable the system to remain the best working condition.

Description

technical field [0001] The invention relates to vehicle power electronics, a high-energy motor, cooling and heating energy exchange, and a vehicle cooling and heating air exchange system driven by a high-energy-efficiency motor with electromechanical integration. Background technique [0002] Domestic status: The core components of electric compressors are currently domestically produced by Nanjing Outejia, Nanjing Yinmao, Shanghai Benling, Shanghai Highly, Shanghai Sanden Bell, etc. Their technical route is DC inverter AC---AC Inverter-driven permanent magnet brushless motor is directly connected to the integrated compressor of the scroll compressor. At present, the driving circuit is unstable, the mechanical processing equipment is backward, the processing accuracy is not enough, and the output power is low. The energy efficiency of the electric compressor The ratio is only about 1.3---1.6, so it is difficult to enter the market in batches. At present, only the electric c...
