The parking air conditioner is a kind of in-car air conditioner. Refers to the continuous operation of the air conditioner with the on-board battery DC power supply (12V/24V/36V) when parking and waiting and resting. The temperature, humidity, flow rate and other parameters of the ambient air in the car are adjusted and controlled to fully meet the comfort cooling needs of truck drivers device of.
Due to the limitation of on-board battery power and the poor user experience of heating in winter, parking air conditioners are mainly single-cooled air conditioners. Generally include cold medium conveying system, cold source equipment, terminal equipment, etc. and other auxiliary systems. Mainly include: 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 condition in the cabin and provide a comfortable resting environment for the truck driver.
According to the survey, long-distance truck drivers drive on the road 80% of the year, and 47.4% of drivers choose to stay overnight in the car. The use of the original car air conditioner not only consumes a lot of fuel, but also easily wears 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 car air conditioner cannot be used when the trucks and construction machinery are parked. It uses DC12V/24V/36V on-board battery to supply power to the air conditioner, without generator equipment; 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 structure is divided into two types: split type and integrated type. Split type is divided into split backpack type and split top type. According to whether frequency conversion can be divided into fixed frequency parking air conditioner and frequency conversion parking air conditioner. The market is dominated by heavy trucks for long-distance transportation, auto parts stores and after-installation in maintenance plants. In the future, it will expand into the engineering field of loading and unloading trucks, and at the same time expand the truck front-loading market, which has broad application development prospects. In response to the complex application scenarios of parking air conditioners, Hisense, Haier, Gree, Midea, and other home appliance companies rely on strong scientific research capabilities to develop a more complete laboratory test environment, covering multiple laboratories including vibration, mechanical shock, and noise Test items.
