How to maintain and handle the industrial water chiller machine when its heat dissipation is poor?

First of all, let’s make clear the sign of poor heat dissipation of the LC -25°C ~ -5°C Low Temperature Chillers. When the condenser of the water chiller has poor heat dissipation, the efficiency of the compressor will be reduced, and the operating current will be increased, resulting in air-cooled high pressure later.

When the air-cooled high-pressure pressure rises to 24kg/cm2, it is a sign of poor heat dissipation of the chiller. At this time, the refrigeration equipment should be maintained in time. The operation of the chiller can be adjusted through professional equipment maintenance for poor heat dissipation of the chiller equipment.

Sometimes, in case of poor heat dissipation, the compressor of the chiller will trip under the protection of the high pressure switch, which will cause the compressor to stop running.

In case of poor heat dissipation, the high pressure overload will display the fault code or fault indication. At this time, please check whether the circulating water of the cooling tower is normal, or shut down and restart to operate normally.

The screw chiller unit changes from the gas refrigerant in the state of from the evaporator to the high temperature and high pressure state after adiabatic compression by the compressor.

The compressed gas refrigerant is cooled and condensed at the same pressure in the condenser. After being condensed, it changes into liquid refrigerant, and then expands to low pressure through the throttle valve to become a gas-liquid mixture.

The liquid refrigerant at low temperature and low pressure absorbs the heat of the cooled material in the evaporator and becomes the gaseous refrigerant again. The gaseous refrigerant enters the compressor again through the pipeline to start a new cycle.

The refrigeration system of the water chiller is a core part of the whole refrigeration equipment. It is crucial for the refrigeration effect of the water chiller equipment as a backup for the refrigeration equipment, but fortunately with the development of science and technology.

1. When the water temperature is above 5 ℃, when the low pressure gauge pressure shows low dry 2kg/cm2, it means that the refrigerant is insufficient. First, make up the leakage at the place where the refrigerant is leaked, then replace the dry filter and vacuum again, and then fill the appropriate refrigerant.

2. When it is found that the leaked refrigerant is partially soaked in water, please immediately stop the operation of the refrigerator, quickly drain the water in the water tank, and notify the company to send personnel to handle and repair as soon as possible, so as to prevent the compressor from sucking water into the system and causing more serious damage.
