Brief analysis of how to carry out the maintenance of the condenser of the water chiller component: the performance of the condenser equipped with any water chiller will gradually decline as it is used for a long time, and the result will make the condensation pressure of the system higher than that of the normal operation. In order not to degrade the nature of the condenser, it is necessary to maintain the condenser regularly.
The condensers used in small refrigeration equipment mainly include air-cooled condensers and water-cooled condensers. Depending on the type of condenser, the way to clean the scale is different. Here are two common condenser maintenance methods:
1. The air-cooled condenser uses air as the cooling medium. Because there is often dust in the air, some of the dust will stick to the outer surface of the condenser fins, which will deteriorate the cooling effect of the condenser over time, especially in places with relatively bad environment, so it should be cleaned regularly. The cleaning method is as follows: pure dust can be blown out with compressor air, etc. If there is much dirt, the cooling pipe and fin should be cleaned with non-corrosive cleaning agent to improve the cooling effect.
2. For water-cooled condensers, the main problem is to remove scale. The cleaning cycle depends on the water quality. If the water quality is poor, it should be cleaned at least once a year; If the water quality is good, it can be cleaned once every 2-3 years.
The small water-cooled chiller is equipped with a sleeve-type water-cooled condenser, which can be pickled. The specific operation method is to remove the condenser, drain the accumulated water, and then inject 10% dilute sulfuric acid solution into the valve until there is a solution outflow position at the outlet. The dilute sulfuric acid can be discharged after it stays in the condenser for 20~30min. Repeat this for two or three times. Finally, install the connecting pipe between the cooling water pipe and the condenser, open the cooling water valve for flushing for 10~20min, and the anti-scaling and cleaning work is over.
In the refrigeration system of industrial water chiller, the compressor, evaporator, condenser and throttling device are the four essential parts of the refrigeration system. The condenser is an equipment that emits heat. The heat absorbed by the evaporator and the heat converted by the compressor work are transferred to the cooling medium to take away. It plays an important role in the refrigeration system. A drop in performance will directly affect the cooling capacity of the water chiller.
