The working principle of truck parking AC mainly relies on the air conditioning system driven by batteries or other devices, which is used when the vehicle is parked and the engine is turned off. This air conditioning system is a supplement to traditional air conditioning, especially in heavy trucks. Parking air conditioners usually have independent compressors and cooling fans, which are powered by the vehicle's battery. Therefore, during the operation of parking air conditioners, battery voltage protection must be provided. For electric vehicles, their parking air conditioners can share a set of compressors and cooling devices with driving air conditioners.
The working principle of parking air conditioners involves the circulation of refrigerants in the air conditioning system. The refrigerant absorbs heat from liquid to gas in the evaporator in the cab, thereby reducing the temperature in the cab. In the condenser, the refrigerant is converted from high-temperature and high-pressure gas to liquid by heat dissipation, taking the heat out of the cab and out of the cab. The core of the car air conditioner is the compressor, which plays a role in promoting the entire refrigerant cycle. Therefore, the most important parts of the entire air conditioning system are three major parts: the evaporator inside the cab, the condenser outside the cab, and the compressor.
The parallel parking air conditioner is a form of self-modification, which is actually a modification of the original parking air conditioner of a high-end model. This type of parking air conditioner connects an electric compressor and an air conditioning compressor in parallel to the air conditioning system, so that the refrigerant can be driven to circulate by the air conditioning compressor when the engine is running, and can also be driven to circulate by the electric compressor when the engine is stopped. This modification ensures that the parking air conditioner can work without the need for the engine to drive it, fully meeting the truck driver's needs for comfortable cooling when parking, waiting, and resting.
