Description
Technical field
The present invention relates to a kind of motorcar electric air-conditioning system.
Background technology
Since automobile came out, the on-board air conditioner system was driven by fuel engines, and not only fuel cost is high, and the motor vehicle exhaust emission amount is big, contaminated environment.Be accompanied by car industry and become increasingly prosperous global, the innovation of on-board air conditioner system and development become an important subject of industry especially.Particularly in China, along with improving constantly of people's material life, car owning amount is also increasing; According to statistics; By 2010,1.95 hundred million on the existing motor vehicle in the whole nation, wherein automobile is more than 8,500 ten thousand; Not only push China the ranks of consumption of petroleum big country, and polluted atmospheric environment.At present, worldwide be in the electric automobile of exploration, starting stage, because use is electric energy, the on-board air conditioner system as kinetic energy can't use on electric automobile with fuel engines.Therefore, electric automobile can't use air-conditioning, and a little less than the batteries of electric automobile electric power storage ability, the two big bottlenecks of become the development of restriction electric automobile, popularizing.So the research electric automobile air-conditioning system also is one of important topic of current electric automobile industry development.
It is reported that existing at present people has designed electric automobile air-conditioning system.This air-conditioning system has only a circuits, when system is warm, adopts heating wire or built-in condenser to warm oneself mostly.Heating wire has the power consumption height, and the life-span is short, because of it can exhaust a part of electric weight, shortens the distance travelled of electric automobile greatly again, and makes battery continuous discharge time decreased, and self flying power of electric automobile " is made the matter worse ".For built-in condenser, the drawback of its existence is that volume is little, and volume is littler; Cold-producing medium can not be dispelled the heat therein fully, will cause heating slowly, system warms up the appearance of problems such as amount is not enough; And a condenser has been installed in driver's cabin more, add it and installed parts inconvenient, many again; Its out of order probability is increased greatly, increase use cost.
Summary of the invention
The objective of the invention is to design a kind of motorcar electric air-conditioning system of forming by a cover system two circuits; Can effectively solve the problem that prior art exists, not only cooling or heating effect is good, speed is fast, and has rapid dehumidifying defrost function; Both convenient the installation practiced thrift cost again.
Realize that the technical scheme that the object of the invention is taked is: this system is made up of battery, electronic controller, motor compressor, condenser, device for drying and filtering, evaporimeter, expansion valve, pressure switch, magnetic valve and each pipeline; It has two cover air-conditioning ducts; In refrigeration pipe; High-pressure side warp first magnetic valve of motor compressor, refrigeration pressure duct, condenser, device for drying and filtering, pressure switch, expansion valve are connected the arrival end of evaporimeter with second magnetic valve, the port of export of evaporimeter is connected the low-pressure end of motor compressor with the 3rd magnetic valve through the refrigeration low pressure line; Heat pipeline by the 4th magnetic valve, heat pressure duct, evaporimeter, dropping valve, gas-liquid separator, heat low pressure line and the 5th magnetic valve is formed; Heat pressure duct one end and be connected the high-pressure side of motor compressor, the other end is connected the port of export of evaporimeter through the 4th magnetic valve; Heat low pressure line one end and be connected the arrival end of evaporimeter, the other end is connected the low-pressure end of motor compressor through dropping valve, gas-liquid separator and the 5th magnetic valve.
Good effect of the present invention is: it is low, simple in structure, easy for installation to have a power consumption, and the trouble point is few, and system is warm fast, and the warm amount of system is higher, and advantage such as reduce cost; Adopt the mode of new forms of energy dc powered, power source is provided,, to motor compressor a normal voltage that intelligence is stable is provided behind the rectifying and voltage-stabilizing, make its system can accomplish normal refrigeration, the warm circulation of system through electronic controller by battery; When system is warm, on former refrigeration system basis, increased by a cover heating air conditioner pipeline; High-temperature high-pressure refrigerant directly gets into the outlet of evaporimeter, flow out from the inlet of evaporimeter, because of the volume of evaporimeter own big; RT was long when cold-producing medium was flowed through evaporimeter; Make the warm speed of its system faster, the warm capacity of system is higher, better effects if.
Description of drawings
Accompanying drawing 1 is a structure principle chart of the present invention.
The specific embodiment
The present invention is shown in accompanying drawing 1; This system is made up of battery, electronic controller 2, motor compressor 5, condenser 8, device for drying and filtering 9, evaporimeter 19, expansion valve 12, pressure switch 11, magnetic valve 4,6,10,13,14 and each pipeline; It has two cover air-conditioning ducts; In refrigeration pipe; The high-pressure side of motor compressor 5 is connected the arrival end 21 of evaporimeter 19 through first magnetic valve 4, refrigeration pressure duct 3, condenser 8, device for drying and filtering 9, pressure switch 11, expansion valve 12 with second magnetic valve 13, the port of export 20 of evaporimeter 19 is connected the low-pressure end of motor compressor 5 with the 3rd magnetic valve 14 through the low pressure lines 18 that freeze; Heat pipeline by the 4th magnetic valve 6, heat pressure duct 7, evaporimeter 19, dropping valve 17, gas-liquid separator 15, heat low pressure line 16 and the 5th magnetic valve 10 is formed; Heat pressure duct 7 one ends and be connected the high-pressure side of motor compressor 5, the other end is connected the port of export 20 of evaporimeter 19 through the 4th magnetic valve 6; Heat low pressure line 16 1 ends and be connected the arrival end 20 of evaporimeter 19, the other end is connected the low-pressure end of motor compressor 5 through dropping valve 17, gas-liquid separator 15 and the 5th magnetic valve 10.
During refrigeration, first, second, third magnetic valve 4,13,14 is opened, and the 4th, the 5th magnetic valve 6,10 cuts out; Battery 1 (12V-24V) provide electrical source of power, carries out power supply voltage stabilizing, incremental conversion through electronic controller 2, drives motor compressor 5 work; After the compressor operating; Cold-producing medium gets into condenser by the air conditioner connecting pipe high-pressure side and the electromagnetism fan carries out being converted into high temperature, high pressure liquid after the high temperature heat radiation, in device for drying and filtering 9, filter and store, and then the expansion valve 12 of flowing through is converted into the liquid state of low temperature, low pressure; Get into evaporimeter 19; By evaporator fan the high temperature in the driver's cabin is carried out cold and hot conversion, become the gas of low temperature, low pressure, thereby accomplish a whole set of air conditioner refrigerating circulation.When air-conditioning work voltage was lower than the electronic controller setting voltage value, the air-conditioning system autostop guaranteed that former car power supply can the normal starting vehicle.
When heating, the 4th, the 5th magnetic valve 6,10 is opened, and first, second, third magnetic valve 4,13,14 cuts out; Through heating the directly port of export 20 of entering evaporimeter 19 of pressure duct 7, because the port of export caliber of evaporimeter 19 is bigger, cold-producing medium reduces at this flow velocity cold-producing medium by motor compressor 5 high-pressure sides; And the volume of evaporimeter own is big, and RT is longer during evaporimeter so cold-producing medium is flowed through, and heating effect is better; And then flow out from the arrival end of evaporimeter 19 21; Through dropping valve 17 step-downs,, gas-liquid separator 15 flows into motor compressor 5 low-pressure ends again after carrying out gas-liquid separation, accomplish heating circulation.
