Air conditioning equipment and its system is more expensive, the value of the assets, how to effectively play the role of the air-conditioned to make it efficient, safe and economical to run its day-to-day maintenance is necessary; regular maintenance can be discharged hidden faults, reduce accidents,reduce operating costs and extend the life of the equipment, and at the same time, to protect the normal timing of the work.

The electrical system of the air-conditioning equipment

1) the long-running air conditioning due to the reason of the wire, components fever and other cause the connector is loose, fall off, resulting in poor contact, lack of phase:

2) AC contactors, thermal relays will also appear poor contact, open circuit failure:

The above failure if not rule out the cause compressor missing phase or three-phase current imbalance is burned. Check the air conditioning repair and maintenance of air conditioning host terminal blocks for loose is very important.
