The quality of the four components of the condensing unit ACV TYPE AIR COOLED COOLED CONDENSER maintenance explanation: Any condenser equipped with a chiller will be used for a long time, and the performance problem will gradually start to decline, and the result may cause the management system. The condensing pressure is significantly higher than the condensing pressure during normal operation of the enterprise. In order not to degrade the properties of the condenser, it is necessary to perform effective maintenance on the condenser on a regular basis.
There are two types of condensers used in box refrigerators: air-cooled and water-cooled. According to the cleaning type of the condenser, the way to clean the scale is also different. The following are two commonly used maintenance of the condenser:
1. The quality ACV TYPE AIR COOLED COOLED CONDENSER uses air as the cooling medium. Since there is often dust in the air, some dust will adhere to the surface of the condenser fins. After a long time, the cooling effect of the condenser will become worse. Especially in places where the environment is relatively harsh, it should be cleaned regularly. The cleaning method is: pure dust can be blown off by compressor air. If there is a lot of dirt, non-corrosive cleaning agent should be used to clean the heat pipe and heat sink to improve the heat dissipation effect.
2. For water-cooled condensers, the main problem is descaling. 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 should be cleaned once every 2 to 3 years. The small water-cooled chiller is equipped with a tube-type water-cooled system condenser, which can be pickled. The specific operation and management method is: remove the condenser, release a large amount of accumulated water, and then inject 10% dilute sulfuric acid reaction solution into the China Pass until there is a solution at a water outlet and the outflow is carried out. After the dilute sulfuric acid stays in the condenser for 20~30min, it can be released. This can be repeated two or three times. After that, install the connecting pipe between the designed cooling water pipe and the condenser, and open the market cooling control water valve to rinse for 10~20min. The service work process is completed.
The quality ACV TYPE AIR COOLED COOLED CONDENSER Four-component condenser heat transfer process: We often talk about the refrigeration heat exchanger of the chiller, mainly referring to the condenser and evaporator in the four major components of refrigeration, which directly affect the absorption and release of the system Thermal capacity and efficiency. Both the condenser and the evaporator are involved in phase change heat transfer, which is the main feature of these two refrigeration heat exchangers. In addition, some refrigeration systems also have intercoolers, subcoolers, etc., the principle of which is similar to that of general heat exchangers.
