How to maintain the condenser of chiller

How to carry out the maintenance work of the condenser of the chiller assembly: the performance of the condenser of any chiller will gradually decline as it is used for a long time, and the condensation pressure of the system will be higher than that of the normal operation. In order not to make the nature of the condenser decline, it is necessary to maintain the condenser regularly.

1. There are two kinds of condensers used in small refrigeration equipment: air-cooled condenser and water-cooled condenser. According to the different types of condensers, the methods of cleaning scale are also different. Here are two kinds of common condenser maintenance: 1. The air-cooled condenser uses air as the cooling medium. As there is dust in the air, some dust will stick to the outer surface of the condenser fin. If the time is long, the heat dissipation effect of the condenser will be worse, especially the comparison of environment Bad place, so it should be cleaned regularly. The cleaning method is as follows: pure dust can be blown away with compressor air. If there is much dirt, the cooling pipe and fin should be cleaned with non corrosive cleaning agent to improve the heat dissipation effect.

2. For water-cooled condenser, the main problem is to remove scale. According to the water quality, the cleaning cycle should be at least once a year for those with poor water quality, and once every 2-3 years for those with good water quality.

3. The condenser equipped with small water-cooled chiller can be cleaned with special cleaning solution for heat exchanger. The specific operation method is: remove the condenser, drain the accumulated water, and then wash the solution into the pipe until there is a solution outflow position at the water outlet. The cleaning solution can be discharged after staying in the condenser for 20 ~ 30min. Repeat this for two or three times. Install the connecting pipe between the cooling water pipe and the condenser, open the cooling water valve to flush for 10 ~ 20min, and the anti scaling and cleaning work is finished.

4. In the refrigeration system of industrial water chiller, compressor, evaporator, condenser and throttling device are the four essential parts of the refrigeration system. The condenser is a kind of heat releasing equipment. The heat absorbed by the evaporator and the heat transformed by the compressor work are transferred to the cooling medium to take away. It plays an important role in the refrigeration system. Once the performance drops, the condenser will directly release heat The cooling capacity of the chiller is affected.
