Principle of air conditioning, heating and cooling for pure electric vehicles

At present, new energy vehicles are the focus of the automobile market. Now that summer has come, air treatment has become the focus of attention. Some people say that the regulations of air pure electric vehicles have a considerable relationship with battery life, but the air regulations are also an item that cannot be ignored in pure electric vehicles. So today we need to give you a brief introduction of /[/k0 pure electric vehicles.

Brief introduction of cooling and heating regulation principle of air pure electric vehicle

Let's briefly talk about how traditional cars are preheated and cooled. The traditional refrigeration mode of an internal combustion engine-driven car is to use the engine to drive the compressor with air conditioning system to realize refrigeration, which is also the reason why the engine power will be reduced when the engine turns on the air conditioning system, and heating is mostly realized through the heat exchange of engine antifreeze.

For pure electric vehicles, because there is no engine cooling system, we can only use paving auxiliary heating for heating function, such as electric heating tube heating as shown in the following figure. It feels similar to the principle of boiling water and hair dryer, but the heating method is a little different. Basically, air is directly heated and then blown into the cab, in addition to PTC heating and heat pump heating. I think this method of paving and heating is also used by internal combustion engines and only applies to buses and trucks. This heating method will also consume the electric energy of the car, which is related to the cruising range of the car.

The refrigeration system of a pure electric vehicle is similar to that of an internal combustion engine vehicle, except that the engine driving the compressor is replaced by a motor. Generally speaking, this kind of motor is independent, but it is also directly driven by the motor that drives the car, which is more similar to the internal combustion engine car. Now the refrigeration problem of electric vehicles can be solved, but the efficiency needs to be improved. We know that most electric vehicles are limited by battery life. Due to the limitation of battery capacity, many early electric vehicles in China were not equipped with air conditioning system.

It can be seen that the design of air conditioning system of pure electric vehicle is largely limited by the cruising range of the vehicle. Therefore, it is necessary to pay attention to the relationship between vehicle performance, especially the relationship between mileage and maximum speed, so as to minimize the energy consumption of air conditioning system.

The refrigeration of pure electric vehicles is similar to that of air conditioners used at home, except that the compressor is replaced by a DC inverter compressor, and the air conditioning pump is driven by a motor through a belt, which directly uses the electricity in the battery, and the power saving effect is very good.

Heating is to replace the hot water tank of a gasoline car with a heating pipe, and the effect is the same. However, the heating of the car will not consume gasoline (because the gasoline car itself must dissipate heat through the water tank, the heat cannot be used as kinetic energy, and it cannot be prevented from losing heat. Only the warm air uses this part of heat energy, so it will not increase fuel consumption), but the heating pipe consumes electric energy.

That's all for today's introduction of the car editor. The above is the heating and cooling principle of pure electric vehicle briefly introduced by automobile editor. Electric cars give us more choices, so air conditioning is very important at present. How much do you know about these principles briefly introduced by the above car editor?
