If the engine and the air conditioning system have a poor cooling condition during the refrigerated truck transportation, the driver should pay attention to it. Because if the refrigerating car 's heat dissipation performance is not good, it will cause the water temperature to be too high and the engine will have abnormal noise. Â 1. When the refrigerated truck is cold, the cooling temperature of the vehicle air conditioner will be relatively low, and the cooling effect of the air conditioner during the hot vehicle is very bad, and there will be a relatively loud squealing sound in the air conditioning system. The emergence of such problems may be due to the replacement of antifreeze or non-standard addition of the antifreeze solution, which eventually leads to the blockage of the refrigerated truck's water tank and waterway and the high water temperature. Antifreeze must be replaced at least once every two years. When adding or replacing, it must be the original manufacturer's accessories. If the refrigerated truck 's engine cooling system is filled with water or the concentration of refilled antifreeze is more than 60%, it will cause the water temperature to be too high. 2. Because the refrigerated truck has too long idle time or there is traffic jam, the display value of the engine water temperature gauge of the vehicle is too high, the operation time of the electronic fan high-speed gear is too long, the noise of the engine is increased, and the air temperature is too high to open the air conditioner. The fault is the most obvious. When the refrigerated truck is hot, check the condition of the return pipe backwater at the upper end of the antifreeze storage tank, as long as the return water is blocked or blocked, it will cause the water temperature to be too high. However, parts cannot be replaced at will during maintenance. Â 3, refrigerated truck open air conditioning when the temperature is relatively high, the idling instability, speed fluctuations are relatively large, but the rapid acceleration is weak, and the engine has an abnormal ring. It is necessary to check if there is too much dust between the water tank and the condenser of the refrigerated truck and use high pressure gas for cleaning. Â 4, when the refrigerated car hot car stalled in more than ten minutes, once you start the vehicle is not easy to get on the car, and when the hot car is running, sometimes there will be automatic shutdown. When the hot car is refrigerated, carefully check the temperature difference between the upper water pipe and the lower water pipe of the lower water tank. If the temperature difference is too large, it is necessary to check whether the water pump of the lower thermostat and the opening degree have the trouble of losing speed. Now.
