Safety Precautions for Industrial Chillers

1. Regularly clean the condenser and evaporator

The condenser/evaporator is the second most important component of the industrial chiller, and it is best to clean it once every six months. The cooling water of the water-cooled condenser is an open circulation loop, and the tap water used is recycled through the cooling water tower, which is easy to decompose and deposit impurities on the water pipe to form scale on the water pipe, which affects the heat transfer effect. If the scale is too thick, the cooling water circulation section will be reduced, the water volume will be reduced, and the condensing pressure will increase. Therefore, when the quality of the tap water used is poor, it is best to clean it at least once a year to remove the scale in the pipe, and it is necessary to perform water treatment operations on the tap water.

2. Regularly check the compressor

The compressor is the “heart” of the chiller, and its quality directly affects the stability of the chiller when it is used. If the compressor fails to be repaired, the cost is relatively high, especially the high precision of the screw compressor is expensive. Therefore, if you hear an abnormal sound from the compressor or other conditions, you must contact the chiller manufacturer to find a professional engineer for overhaul, find out the cause and carry out maintenance.

3. Regular inspection of safety valve

The condenser and evaporator of the industrial chiller are pressure vessels. According to the regulations, a safety valve should be installed on the high-pressure end of the chiller, that is, the condenser body. Once the equipment is in an abnormal working environment, the safety valve can automatically release pressure. , to prevent possible damage to the human body caused by high pressure.

4. Replace the filter drier regularly

The filter drier is an important part to ensure the normal circulation of the refrigerant. Since water and refrigerant are immiscible with each other, if the system contains moisture, it will greatly affect the operating efficiency of the chiller. Therefore, it is very important to keep the inside of the system dry, and the filter element inside the drying filter must be replaced regularly.

5. Regularly replace the lubricating oil

After the industrial chiller is used for a long time, the oil quality of the lubricating oil will deteriorate, and the impurities and moisture inside the oil will increase, so it is necessary to observe and check the oil quality regularly. Once a problem is found, it should be replaced in time, and the brand of lubricating oil to be replaced is best provided by the original manufacturer.
