2015-12-23 11:19:39

After using for a long time, we will find that the cooling effect of bus air conditioner is not good than before. Following we will introduce the reasons that cause those phenomenon and how to solve it.

First, the refrigeration is too little. After using for a period of time, the refrigeration will be reduced. The consumption of refrigeration is mainly because of the leak out. When the leak out is serious, we should check it and avoid this phenomenon.
Second, the damage of bus air conditioning flap. This fault are rare, but it is also troublesome. The motor of air conditioning flap is under the control desk, which belongs to the main switch of air conditioning. When all the outlet cannot blow the wind, we should pay more attention. 
Three, the dirty condenser. When the air conditioning system is working normally, we can clean the water tank and condenser to have good heat dissipation effect. In the spring, we should clean the condenser timely to avoid the bad cooling ability.
Four, the damage of throttle valve or expansion valve.  The damage of throttle valve or the expansion valve will lead the bad cooling effect of bus air conditioner. When this phenomenon occurs, we should ask the technological operation for help.
