The parking air conditioner is a kind of air conditioner in the car. When parking, waiting and resting, the car battery DC power supply (12V/24V/36V) is used to make the air conditioner run continuously. Adjust and control to fully meet the comfort and cooling needs of truck drivers.
Due to the limited power of the on-board battery and the poor user experience of heating in winter, the parking air conditioner is mainly a cooling-only air conditioner. It generally includes cold medium medium delivery system, cold source equipment, terminal devices, etc. and other auxiliary systems. It mainly includes: condenser, evaporator, electric control system, compressor, fan and pipeline system. The terminal device uses the cold energy from the transmission and distribution to specifically deal with the air state in the cabin and provide a comfortable rest environment for truck drivers.
According to a survey, long-distance truck drivers spend 80% of their time on the road in a year, and 47.4% of drivers choose to spend the night in their vehicles. Using the original car air conditioner not only consumes a lot of fuel, but also easily wears out the engine, and even risks carbon monoxide poisoning. Based on this, the parking air conditioner has become an indispensable long-distance rest companion for truck drivers.
The parking air conditioner is a supporting facility for trucks, trucks, and construction machinery, which can solve the problem that the original vehicle air conditioner cannot be used when the truck or construction machinery is parked. DC12V/24V/36V on-board battery is used to power the air conditioner, and no generator equipment is required; the refrigeration system uses safe and environmentally friendly R134a refrigerant as the refrigerant. Therefore, the parking air conditioner is a more energy-saving and environmentally friendly electric drive air conditioner.
Compared with traditional car air conditioners, parking air conditioners do not need to rely on vehicle engine power, which can save fuel and reduce environmental pollution. The main structural forms are divided into two types: split type and integrated type. The split type is divided into split backpack type and split top type. According to whether the frequency conversion can be divided into fixed frequency parking air conditioner and variable frequency parking air conditioner. The market is dominated by heavy trucks for long-distance transportation, after-loading in auto parts cities and maintenance factories. In the future, it will expand to loading and unloading trucks in the engineering field, and at the same time expand the truck front-loading market, which has broad application and development prospects. Aiming at the complex application scenarios of parking air conditioners, many companies rely on strong scientific research capabilities to develop a more complete laboratory testing environment, covering a number of laboratory testing items including vibration, mechanical shock, and noise.
