In the scorching sun, whether it is long-distance driving or parking for a rest, the truck air conditioner is the closest partner of the truck driver. Due to the hot weather, should the engine be turned off or the A/C be turned off first when parking? Many drivers often turn off the truck air conditioner after turning off the engine, in fact, this approach is harmful to the engine, because when the vehicle is started next time, the engine will start with the load of the air conditioner, and such a high load will damage the engine. It is recommended that truck drivers should first open the window when using the truck air conditioner while driving, then open the outside circulation to replace the stuffy air, and finally switch to the inside circulation.
Regular care and maintenance of truck air conditioners:
(1) Compressor inspection and maintenance. Generally, it is carried out every three years, mainly to check whether the suction and discharge pressure meet the requirements, whether the fasteners are loose, whether there is air leakage, etc. After dismantling, mainly to check whether the suction and discharge valve plates are damaged or deformed, and if necessary, repair or replace them. After disassembly, mainly check whether the suction and discharge valve plates are damaged or deformed, and if necessary, repair or replace the suction and discharge valve assembly. After the compressor is disassembled and repaired, the seal rings and shaft seals must be replaced, otherwise it will cause leakage at the seal of the compressor.
(2) Inspection and maintenance of the condenser and its cooling fan. Generally, once a year, the maintenance content is mainly to thoroughly clean or remove the impurities and dust on the surface of the condenser, repair the heat sink of the condenser with a flat paddle, carefully check whether there is any abnormality on the surface of the condenser, and use a leak detector to check whether there is any refrigerant. No leaks. Such as anti-rust paint peeling.
(3) Evaporator inspection and maintenance. Generally, a leak detection operation should be carried out once a year with a leak detector. Every 2 to 3 years, the cover of the evaporator should be removed and the inside of the evaporator should be cleaned to remove the debris in the air intake duct.
(4) Replace the liquid storage dryer. Under normal use of truck air conditioners, a liquid storage dryer is usually replaced every 3 years. If the system gets into water due to improper use, it should be replaced in time.
(5) Expansion valve maintenance: Generally, check every 1 to 2 years whether its operation is normal and the opening is appropriate. If it is abnormal, it should be replaced or adjusted accordingly.
(6) Maintenance of refrigeration system piping: ①Pipe connections: Inspect once a year and check their sealing condition with a leak detector. ②Refrigeration system connecting pipe: Check whether it collides with other parts, check whether the hose is aging or cracked, and generally replace the hose every 3 to 5 years.
(7)Inspection and replacement of safety devices. Safety devices such as high and low voltage switches, which are related to the safe and reliable operation of the air conditioner, should generally be checked once a year. Replace every five years.
