Taught you how to detect air conditioning common fault

Today, had already gone into the fall, many domestic air conditioning also nearly all the "rest", and after so long time use, it is back to some small failures occur.

Because many consumers in air-conditioning maintenance knowledge deficiency occurs when air conditioning is small failure, don't take a huge cost for maintenance workers, as a result they settle down three to two.

In order to allow friends to air conditioners have a better understanding of, and able to resolve some minor glitches, small series specifically for fault resolution summarizing some of the common knowledge and methods, interested friends can look together.

Phenomenon of a lack of air conditioning air-conditioning output: in use, sometimes you will find air conditioning of the air volume is smaller, air-conditioning, if there is a phenomenon occurring, then you can on the basis of the following ways on detect air conditioning: 1, input 2 stomatal is closed, the condenser coil clean with the heatsink is 3, the refrigerant in the system adequacy 4, blower motor is working 5, blower channel is blocked if the intake air filter element 6, block 7, evaporator is blocked according to the following kinds of phenomenon can figure out your air conditioner there have failed: 1, if the pressure table shows normal pressure and low pressure table shows high pressure on the evaporator pressure regulator, hot gas bypass valve, inlet throttle valve failure; 2, if the exhaust air temperature is high, and the pressure gauge pressure indicates normal, or high-voltage increase slightly, the expansion valve filter blocking; 3, if the pressure table indicates more than normal pressure, low pressure table indicates less than normal pressure, while receiving the dryer and pipes freeze, you receive the dryer filter blocking; 4, if the pressure table indicates more than normal pressure, the system may have excessive moisture.

If the observation window there is a bubble, mixed with air in the system description.
