【文章內(nèi)容簡介】 using R134a refrigerant electric car airconditioning heat pump system, the heat pump system used in the car inside air condenser and evaporator structure. Electric ( DENSO ) Company in 2021also developed as a result of natural refrigerant CO2good thermal physical properties, Denso Japan pany for electric car develops a set of CO2 heat pump air conditioning system, also used in the air duct system is arranged in the2heat exchanger, and R134a system is different when the system for refrigeration mode when the refrigerant flows through the condenser, and internal and external condenser. In order to reduce the air conditioning on battery power consumption, the United 4 States of America Amerigon pany developed airconditioning seat, the chair is provided with a thermoelectric heat pump, heat pump action is through the need to regulate the temperature in space outside the water tank to transfer heat, thereby realizing the need to regulate the temperature of space refrigeration or heating. This kind of air conditioning seat in addition to energy saving but also can improve the driving, riding fort, in electric vehicle supporting the use of suitable. Therefore, the foreign electric automobile air conditioner from energy efficient and practical breakthrough, domestic electric car airconditioning industry should actively to study overseas advanced technology, draw lessons from, and on the basis of innovation breakthrough. 4． the development trend of electric vehicle air conditioning Electric automobile driving energy from the battery, which is different from the traditional fuel automobile, made it to the air conditioning system also differed from the fuel of automobile air conditioner, as a drive source of energy for the limited battery capacity, the energy consumption of air conditioning system on electric vehicle mileage has bigger effect. Compared with cars, car air conditioning system energy saving and high efficiency raised taller requirement. At the same time, the electric car airconditioning refrigeration, heating to solve two problems. According to the electric car special properties, the electric automobile air conditioner using thermoelectric ( I ) air conditioning system and electric heat pump type air conditioning system. 1).a thermoelectric ( I ) electric vehicle air conditioning system The technology has many suitable for electric vehicles use characteristics, and with the traditional mechanical pression type air conditioning system pared, thermoelectric air conditioning has the following characteristics: ① thermoelectric elements work to DC power supply。 ② change the direction of the current to generate refrigeration, heating the converse effect。 ③ thermoelectric refrigeration piece of thermal inertia is small, cooling time is very short, the hot end heat well cold end load cases, energized in less than a minute, the refrigeration sheet can achieve the maximum temperature difference。 ④ ponent for regulating current size can adjust refrigeration speed and temperature, the temperature control precision can reach ℃ , and can easily realize the continuous regulating energy。 ⑤ in the correct design and application conditions, the refrigeration 5 efficiency can reach above 90%, and the heating efficiency is greater than 1。 ⑥ has the advantages of small volume, light weight, pact structure, reduces the electric vehicle kerb mass。 high reliability, long service life and convenient maintenance。 no moving ponents, therefore, no vibration, no frict
