Abstract
The invention discloses a cold-warm air interchange system of a vehicle air conditioner. The cold-warm air interchange system comprises an electrically driven compressor, a condenser, a condensation fan, an expansion valve, an evaporator, an evaporation fan and an electronic control system which are connected by a pipeline to be a seal system, wherein the heating is achieved by using the electronic control system to control a four-way valve and an unilateral electromagnetic valve, exchanging the functions of the condenser and the evaporator, and using a heating pump theory to heat, and further adding PTC (phenylthiocarbamide) to heat and compensate in high cold climate. According to the cold-warm air interchange system, the electrically driven compressor plays roles of compressing and transporting refrigerant steam; the electronic control system is used for calculating by a mathematical model and experience data according to the parameters of each sensor (temperature, pressure and so on), to accurately control the rotation speed of the electrically driven compressor, the opening degree of the electronic expansion valve and the reasonable air volume of the fan, so that the optimal work state of the system is kept all the time.
Description
Technical field
The present invention relates to the car air-conditioner cold and heat air exchange system that new-energy automobile is used for power electronics, high energy motor, changes in temperature energy exchange, electromechanical.
Background technology
Known domestic used in new energy vehicles air conditioner cold-warm air exchange system, the ubiquity drive circuit is unstable, and machining equipment falls behind, and machining accuracy is inadequate, and power output is on the low side, and the Energy Efficiency Ratio of motor compressor only has about 1.3-1.6, and very difficult batch comes into the market.The motor compressor comparative maturity that only has Japan electric coating (DENSON), but price is strange high and additional conditions are arranged.The producer of domestic New energy air-conditioning system technology maturation is very few, does not also have ripe control theory and the strategy of a cover, so that the Energy Efficiency Ratio of electric air-conditioning system is higher.
Summary of the invention
Present situation for present domestic used in new energy vehicles air-conditioning, the object of the invention is to a kind of car air-conditioner changes in temperature, that electronic control system is controlled the rotating speed of motor compressor, the aperture of electric expansion valve and the reasonable air quantity of blower fan accurately according to each sensor, solve the critical components such as electric cooling-heating air-conditioning system, battery pack heat management system, make system keep optimum Working always.
Technical scheme of the present invention is achieved in the following ways: the car air-conditioner changes in temperature, by motor compressor, condenser, condensation fan, expansion valve, evaporimeter, evaporation fan and electronic control system form, by pipeline it is linked to be the system of a sealing, refrigeration is cold-producing medium carries out heat exchange with air in evaporimeter after, enter motor compressor after being gasificated into low temperature and low pressure steam, condenser, dry, filter, after the expansion, the two-phase mixture that is formed by gas and liquid, enter again evaporimeter, absorb heat, reduce temperature, it is characterized in that: described heating is electronic control system control cross valve and Unidirectional solenoid valve, the function of condenser and evaporimeter is exchanged, utilize heat pump principle to heat, under puna, also need add the PTC heat make-up.
The present invention, in whole cyclic process, motor compressor plays a part compression and refrigerant conveying steam, electronic control system is then carried out computing according to the parameter of each sensor by Mathematical Modeling and empirical data, control accurately the rotating speed of motor compressor, the aperture of electric expansion valve and the reasonable air quantity of blower fan, make system keep best duty always.

The specific embodiment
A kind of used in new energy vehicles air conditioner cold-warm air exchange system, formed by motor compressor 1, condenser 2, condensation fan 3, expansion valve 4, evaporimeter 5, evaporation fan 6 and electronic control system, by pipeline it is linked to be the system of a sealing, refrigeration is cold-producing medium carries out heat exchange with air in evaporimeter 5 after, after being gasificated into and entering motor compressor 1, condenser 2, drying, filtration behind the low temperature and low pressure steam, expanding, the two-phase mixture that is formed by gas and liquid, enter again evaporimeter 2, absorb heat, reduce temperature.Heating is electronic control system control cross valve 7 and Unidirectional solenoid valve 8, and the function of condenser 2 and evaporimeter 5 is exchanged, and utilizes heat pump principle to heat, and also need add the PTC heat make-up under puna.
During work, cold-producing medium carries out heat exchange with the interior air in evaporimeter after, enter motor compressor 9 after being gasificated into low temperature and low pressure steam, raise by temperature, pressure after the compressor compression, then enter condenser, high-temperature high-pressure refrigerant steam and car outer air are carried out heat exchange, become liquid after being cooled, behind the drying storage solution device dry filter, the cold-producing medium high temperature high pressure liquid of leaving condenser is flowed through behind the expansion valve 4, reduces pressure and temperature, become the two-phase mixture that is formed by gas and liquid, enter again evaporimeter, absorb the evaporimeter heat of object on every side, its temperature is reduced.So go round and begin again and finish kind of refrigeration cycle.Heat cyclic process then by electronic control system control cross valve and Unidirectional solenoid valve, the function of condenser and evaporimeter is exchanged, utilize heat pump principle to heat, but this heating method is only more effective under low cold air time condition, also need add the PTC heat make-up under puna.
