More and more air conditioners are entering people's homes, not only in cities, but also in rural areas. The use of air conditioning is really more and more extensive. But after using it for a long time, there will always be some minor problems more or less. I don't know how everyone solves it In fact, everyone should know how to maintain the air conditioner when using it. Good maintenance methods will prolong the life of air conditioners.

Common faults of Haier central air conditioning

1. Causes and solutions of indoor noise exceeding design requirements.

(1) The fan noise is higher than the rated value. Please measure the noise of the fan, check whether the fan impeller touches the casing, whether the bearing is damaged, and whether the shock absorption is good, and carry out symptomatic treatment.

(2) The wind speed of air ducts, valves and tuyeres is too high, which will produce airflow noise. Please adjust various valves and tuyeres to reduce excessive wind speed.

(3) The muffler equipment of the air duct system is not perfect. Please add muffler bending equipment.

2. Causes and solutions of dead angle caused by uneven distribution of indoor wind speed.

(1) airflow organization design is not well considered. According to the measured air distribution map, adjust the position of air supply outlets or increase the number of air supply outlets.

(2) The air volume adjustment at the outlet of air supply is uneven and does not meet the design value. The air volume of each air supply outlet should be adjusted to meet the design requirements.

3. The reason why the measured air volume of the system is less than the designed air volume and the solution.

(1) The actual resistance of the system is greater than the design resistance, and the air volume of the fan decreases. If conditions permit, improve the air duct to reduce the system resistance.

② The system is blocked. Please check and clean the possible blockage in the system.

(3) The system leaks, and the leaking place should be blocked.

(4) The fan fails to meet the design capacity or the impeller rotates in the wrong direction, and the belt slips. , and check and eliminate the factors that affect the fan output.

4. The causes and solutions of the measured air volume of the system being greater than the designed air volume.

(1) The actual resistance of the system is less than the design resistance, so if conditions permit, increase the air volume of the fan and change the number of revolutions of the fan.

(2) The fan capacity is too large during design. Please turn down the air volume control valve to reduce the air volume.

5. The reasons and solutions for the inconsistency and big difference between the total air supply and the total air intake of the system.

(1) The measurement method and calculation of air volume are incorrect. Please refer to the measurement and calculation data.

(2) If the system leaks air or the air flow is short-circuited, please check the blockage and eliminate the short circuit.

6. Causes and solutions of slow indoor refrigeration caused by normal or too low dew point temperature of the machine.

(1) The air supply volume is less than the design value, and the air exchange frequency is less. Please check whether the fan model meets the design requirements, whether the impeller rotates correctly, whether the belt is loose, and open the large air supply valve to eliminate the factors of insufficient air supply.

(2) The system has secondary return air, which is too large. Please adjust and reduce the secondary return air.

(3) There are many rooms in the air conditioning system, and the air volume distribution is uneven. Please adjust it so that the air volume in each room is evenly distributed.
