Central air conditioning is a large-scale air conditioning equipment and an indispensable part of modern buildings. However, when the central air conditioner fails, it will bring great trouble to users.

There may be various reasons for the failure of the central air conditioner, such as mechanical failure, electronic failure, electrical failure, etc. The following are some common causes of failure:

1. Air conditioning overload: due to long-term operation or refrigerant leakage, the air conditioning load is too large, leading to the failure of the central air conditioning.

2. electrical fault: the central air-conditioning circuit is short-circuited or blocked due to aging or short-circuit of wires.

3. Control failure: The control panel, temperature sensor and other equipment are out of order, resulting in the central air conditioner not working normally.

4. Refrigerant problem: Refrigerant is one of the keys to the operation of central air conditioning. If the amount of refrigerant is insufficient or the system leaks, the central air conditioning will not work normally.

we need to take timely measures to solve the problems of central air conditioning. The following are several possible solutions:

1. Regular maintenance: In order to avoid the failure of the central air conditioner, we need to carry out regular maintenance, clean the filter screen and condenser of the air conditioner, and check the status of electrical components and refrigerants.

2. Repair or replacement: For the central air conditioner that fails, it is necessary to find professional maintenance personnel or replace parts to ensure its normal work.

3. Pay attention to performance selection: When purchasing a central air conditioner, you need to pay attention to its applicability and durability. Choosing a central air conditioner with good performance can avoid the possibility of failure.

to sum up, central air-conditioning failure is a common situation, which requires us to take timely and effective measures to solve it. We can avoid the occurrence of air conditioning failures by regular maintenance, repair or replacement, and paying attention to performance selection.
