The RV/Truck parking air conditioner is a kind of air conditioner in the car. Refers to the car battery DC power supply (12V/24V/48V/60V/72V) used to make the air conditioner run continuously when parking, waiting and resting, and adjust and control the temperature, humidity, flow rate and other parameters of the ambient air in the car to fully meet the requirements of the truck. Equipment for the driver's comfort and cooling needs.
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 matched with 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/48V/60V/72V on-board batteries are 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 leading manufacturers of parking air conditioners have developed a more complete laboratory testing environment relying on their strong scientific research capabilities, covering a number of laboratory testing items including vibration, mechanical shock, and noise.
According to the installation method, the main structural forms of the parking air conditioner are divided into two types: split type and integrated type. The split unit adopts the design scheme of the household air conditioner, the inner unit is installed in the cab, and the outer unit is installed outside the cab, which is the current mainstream installation type. Its advantage is that due to the split design, the compressor and condenser fan are outside the compartment, the running noise is low, the installation is standardized, fast and convenient, and the price is low. Compared with the top-mounted all-in-one machine, it has a certain competitive advantage. The truck all-in-one air conditioner is installed on the roof of the car, and its compressor, heat exchanger, and exit door are integrated together. The integration is particularly high, the overall appearance is beautiful, and the installation space is saved. It is currently the most mature design solution.
