Air conditioning more and more into people's homes, not only the city has air conditioning, even the rural areas are basically covered, the use of air conditioning is really more and more extensive. But we use for a long time there will always be more or less small faults, I do not know how we all solve it. In fact, we should know how to maintain the use of air conditioning. Good maintenance methods will make the air conditioning life longer.
To regularly clean the air conditioning on the dust, because the dust is easy to block the filter, so that the filter can not better filter out some harmful substances. Here's a look at what are the common faults of air conditioners.
Service process is as follows:
1 call the hotline;
2 register for an appointment
3 on time

5 determine the cost
6 troubleshooting
7 fill in the vouchers
8 provide a warranty.

Repair Scope:
Haier Central Air Conditioning Air Conditioning Repair Failure: no heating, no refrigeration, leakage, line repair The first test, quote, the customer agreed to start repairing. No security guarantee is not repaired, not to cure the root of not repaired, no repair value is not repaired; do not waste customers a penny. The user acceptance before the completion of the repair, open the bill and warranty card. After repairing the return visit, ask about the use of home appliances and charge details.
Haier central air conditioning common failures
1, indoor noise is greater than the design requirements of the reasons and solutions.
(1) Fan noise is higher than the rated value, please measure the fan noise, check whether the fan impeller is touching the shell, whether the bearings are damaged, whether the damping is good, and symptomatic treatment.
(2)The air velocity of air ducts, valves and air outlets is too high, which will produce airflow noise. Please adjust various valves and air outlets to reduce the excessive air velocity.
(3)The anechoic equipment of the duct system is not perfect, please increase the anechoic bending equipment.
2, the indoor wind speed distribution is not equal to the cause of dead ends and solutions.
(1)The airflow organization design is not well considered. According to the measured airflow distribution map, the position of the air supply port should be adjusted or increase the number of air supply ports.
(2) The adjustment of air volume at the air supply outlet is not uniform and does not conform to the design value. The air volume of each air supply outlet should be adjusted to meet the design requirements.
3, the system measured air volume is less than the design air volume of the reasons and solutions.
(1) the actual resistance of the system is greater than the design resistance, fan air volume is reduced, when conditions allow, improve the duct components, reduce system resistance.
(2) the system is clogged, please check and clear the system may be clogged.
(3) The system is leaking, you should plug the loophole.
(4) The fan does not reach the design capacity or the impeller rotates in the wrong direction, the belt slips, etc., check and exclude the factors affecting the fan output.
4, the measured air volume of the system is greater than the design air volume of the reasons and solutions
(1) the actual resistance of the system is less than the design resistance, so increase the air volume of the fan, and change the number of fan revolutions when conditions allow.
(2) The fan capacity was too large at the time of design. Please turn down the air volume control valve to reduce the air volume.
5, the system's total air supply and total air intake is not consistent, the difference between the causes and solutions
(1) air volume measurement method and calculation is not correct, please consult the measurement and calculation data.
(2) The system leaks air or the airflow is short-circuited, please check the blockage and eliminate the short-circuit.
6, the machine dew point temperature is normal or low, indoor cooling slow causes and solutions.
(1)The air supply is less than the design value, and the number of air changes is low. Please check whether the fan model meets the design requirements, whether the impeller rotation is correct, whether the belt is loose, and open the large air supply valve to eliminate the factors of insufficient air supply.
(2) The system has a secondary return air, the secondary return air volume is too large, please adjust, reduce the secondary return air volume.
(3) The air conditioning system has many rooms and the air volume is not evenly distributed. Please adjust it so that the air volume in each room is evenly distributed.
