Key applications in air conditioning systems

• Core link of refrigeration cycle: In the refrigeration cycle of Volvo truck air conditioning, the condenser plays a key role in connecting the upper and lower parts. The high-temperature and high-pressure gaseous refrigerant coming out of the compressor enters the condenser. For example, when the air conditioner is turned on, the refrigerant is compressed by the compressor, the temperature can rise to about 70-80℃, and the pressure also rises accordingly. At this time, the refrigerant enters the condenser, and through the heat exchange between the condenser and the outside air, the heat of the refrigerant is dissipated, the temperature and pressure gradually decrease, and it becomes a medium-temperature and high-pressure liquid refrigerant. This process is the key to the conversion of the refrigeration cycle from the high-temperature heat dissipation stage to the low-temperature heat absorption stage (evaporator link). Without the effective operation of the condenser, the refrigeration cycle cannot proceed normally.

• Ensure the comfort in the car: Its efficient operation is directly related to the cooling effect in the car. In hot weather, if there is no good cooling environment in the truck cab, the driver is prone to fatigue, affecting driving safety. The condenser continuously dissipates the heat of the refrigerant, providing the prerequisite for the subsequent evaporator to absorb heat in the car, thereby effectively reducing the temperature in the car and maintaining a comfortable driving and riding environment. It can usually reduce the temperature in the car to around 20-25℃. The specific temperature will also vary depending on factors such as ambient temperature and air conditioning system power.
