With the arrival of winter, the whole country has also experienced one cold wave after another, and the gradually decreasing temperature has made people more and more resistant to going out. For many northern car owners, just enter the car before going to work every morning, it is bound to be a cold air, and the various objects in the car are always extra cold, so they have to heat the car before driving.
Compared with traditional fuel vehicles, the experience of new energy car owners in winter is even worse. Because the new energy vehicle itself will be greatly reduced in the follow-up mileage in the winter, coupled with the on-board air conditioning will significantly increase the power consumption of the car, so many car owners prefer to endure the cold rather than turn on the air conditioning for heating. After noticing this situation, major car companies have also begun to increase the research and development of pure electric vehicle on-board air conditioning, and strive to provide car owners with air conditioning devices that can save more electricity, and heat pump air conditioning was born in this context.
What is heat pump air conditioning
The biggest difference between heat pump air conditioning and ordinary car air conditioners is that there is an additional heat pump, and the role of this heat pump is to carry water and heat. The gaseous refrigerant compressed by the electric compressor is in a state of high temperature and high pressure, and then it is changed back to the liquid state through the internal condenser, and the heat pump air conditioner is to achieve the purpose of blowing out the warm air by carrying the heat generated in this process. Conversely, it's the same in the summer when you need to blow cold winds. The only regret is that the production cost of heat pump air conditioners is relatively high, so it has not been fully popularized to all new energy vehicles, and only some more expensive models will be equipped with heat pump air conditioners.
Characteristics of heat pump air conditioning
The main role of heat pump air conditioning and ordinary car air conditioning is the same, which is to control the temperature inside the car. However, compared with ordinary car air conditioners, the working principle and energy consumption of heat pump air conditioners are different from ordinary air conditioners. For fuel vehicles, the pressure of the winter wind on fuel consumption is very small, because the warm air of the fuel vehicle can be said to be a waste utilization, which is to achieve the effect of heating through the waste heat generated by the engine. However, because the new energy vehicle does not have an engine, it cannot be heated in this way, and can only play a role in heating the airflow by heating the heating wire, so that the heating process will inevitably consume a lot of electrical energy.
The heat pump air conditioner is different, as I said before, the main function of the heat pump air conditioner is to carry the heat generated by the electric compressor during work, so it is very good in electric energy consumption, compared with the simple structure of PTC air conditioning, it can save more electricity and ensure the mileage of new energy vehicles. If you look at it according to the endurance standard, the 100 km endurance of the heat pump air conditioner is about 30 km more than that of the PTC air conditioner.
However, it is worth noting that although the heat pump air conditioner has excellent results in energy consumption, in the relatively cold weather, its specific heating effect is not as good as PTC air conditioning, and the warm air comes slower, which is due to the fact that part of the heat will be consumed during the handling process. On the other hand, compared with PTC air conditioners, the cost of heat pump air conditioners is also relatively high, and often requires car owners to spend more money to buy.
summary:
Although the heat pump air conditioner alleviates the endurance problem of new energy vehicles in winter to a certain extent, it does not fundamentally solve the situation that the mileage of new energy vehicles will be halved in winter. Therefore, for major car companies, the most important thing is to work new energy vehicle batteries to make the batteries of new energy vehicles more durable and more resistant to low temperatures.
