Common failure problems of air coolers are mainly in the following categories:

Poor cooling effect

Insufficient air flow: Fan failure, such as motor damage, deformation or loosening of fan blades, will result in the fan failing to operate normally or lowering the rotational speed, so that air flow is reduced. In addition, the air inlet or outlet of the cooler is blocked, such as by the accumulation of dust and debris, will also hinder air flow, reducing the cooling effect.

Cooling water piping problems: scaling inside the cooling water piping will reduce the heat exchange efficiency and affect the cooling effect. Or there is air accumulation in the pipeline, the formation of air resistance, resulting in poor cooling water circulation, will also cause poor cooling effect.

Refrigerant problem: refrigerant leakage in the system, resulting in insufficient cooling capacity, unable to effectively cool. In addition, too much or too little refrigerant charge will affect the normal operation of the refrigeration cycle, which in turn affects the cooling effect.

Abnormal Noise

FAN NOISE: The fan motor bearings are worn out, and abnormal noise will be produced during operation. Friction or collision between the fan blades and other parts will also produce noise.

Mechanical vibration noise: The installation of the cooler is not firm, and the noise will be generated by vibration during operation. Or the internal parts are loose, such as compressor, pump, etc., which will also cause vibration and noise.

Leakage Problems

Refrigerant Leakage: Poor sealing of pipes, joints, valves and other parts of the refrigeration system can lead to refrigerant leakage. Leakage may also be triggered by aging and corrosion of pipes after long-term use.

Cooling water leakage: Poor sealing of the connections of cooling water piping can easily lead to leakage. Ruptured water pipes and damaged radiator cores can also lead to cooling water leaks.

ELECTRICAL FAILURES

MOTOR FAILURES: A burnt or shorted fan motor or compressor motor will prevent the unit from operating normally. Damage to the motor's starting capacitor will also cause the motor to fail to start or run abnormally.

Control Circuit Failure: Damage to components on the control circuit board, such as relays, contactors, etc., can affect the control function of the cooler, resulting in the equipment failing to operate according to the set program. In addition, problems such as line breaks and short circuits will also affect the normal operation of the electrical system.
