How to repair the fault of central air conditioning

Central air conditioning is a relatively large air conditioning system. Because of its large volume and complex equipment, the possibility of failure will increase and it needs to be overhauled and maintained. The following are the specific steps:

1. Troubleshooting: conduct a comprehensive inspection of the central air conditioner, determine the fault, check whether the machine parts are loose and worn, and test and check the circuit.

2. Disassembly inspection: If the specific fault is determined, it is necessary to disassemble the equipment to inspect the inside, and the air conditioning and refrigeration system, exhaust fan and other components can be inspected.

3. Maintenance and cleaning: After the inspection, thoroughly clean the air outlet, heat exchanger, radiator and other components of the air conditioner, and at the same time clean and repair the condenser to ensure the heat dissipation effect required for the normal operation of the equipment.

4. Replace parts: If any parts are damaged or aged, they need to be replaced in time. Common fault parts are: air conditioning compressor, engine and motor, evaporator, heat exchanger and air duct, etc.

5. Check the circuit: If the circuit fails, there will be problems such as short circuit and grounding, so it is necessary to check and repair the circuit.

In a word, the maintenance of central air-conditioning fault is a complicated work, which needs professional inspection and cannot be changed without permission, so as not to cause greater losses.
