The energy-storage vehicle-mounted air conditioning system can be applied to a traditional internal combustion engine driven vehicle, and can also be applied to a new energy vehicle, such as a pure electric driven vehicle, a hybrid vehicle, a hydrogen fuel driven vehicle and the like.
Background
The vehicle air conditioner is a device for adjusting the temperature and humidity of air in a vehicle room to provide a comfortable environment for driving and riding people.
Under the guidance of national policy of energy conservation and emission reduction in China, new energy automobiles enter thousands of households orderly and steadily, and new experience is provided for users. However, in use, people find that the comfort level of the new energy automobile is reduced because the power consumption of the automobile air conditioner is large and even accounts for one third of the total power consumption of the new energy automobile, the endurance time of the automobile is shortened, and the use intensity of the automobile air conditioner is reduced or reduced. Under the restriction of effective electric energy storage, the main subject to be solved by the invention is to develop a new energy automobile air conditioner which does not affect the endurance length and can improve the user experience.
The most intuitive development of the logistics industry is that trucks which are always on the highway are transported for a long time and remotely in hot summer, and the energy and physical strength of drivers and passengers are consumed. Especially, at night, when a driver needs to stop for a rest, the air conditioner is started to cool the interior of the cab. The long-time use of the vehicle-mounted air conditioner of the truck under the waiting state not only has high cost and is easy to cause carbon deposition of the engine, but also can cause the damage of the engine for a long time.

Although the parking air conditioner solves the problem of cooling of the cab during parking, after the parking air conditioner is used for a long time, obvious defects can occur in the two power supply modes. The power generator is used for supplying power to the parking air conditioner when parking, the consumption of fuel oil is huge, the vehicle-mounted power generator is used for continuously supplying power according to data display, the oil consumption is about 3L per hour, the price of diesel oil is about 6.5 yuan per liter, and the cost is close to 20 yuan; and adopt the mode of installing the storage battery additional and supplying power, because the electric capacity of storage battery is limited, consequently can't supply power for a long time, supply power to the parking air conditioner can lead to the storage battery to discharge too fast moreover, and frequent quick discharge causes not little injury to storage battery itself, shortens the life of storage battery. According to statistics, the storage battery is basically replaced once a year by adopting a mode of supplying power by the storage battery, the cost is high, and the parking air conditioner cannot obtain enough electric quantity to continuously refrigerate for a long time. Therefore, the development of a parking air conditioner with low cost and convenient use is a secondary subject of the present invention.
