BOX TYPE BITZER CONDENSING UNIT four parts of the condenser maintenance explanation: any condenser equipped with a chiller, the performance will gradually decline over a long period of time, as a result, the condensing pressure of the system will be higher than that during normal operation. pressure. In order not to degrade the properties of the condenser, it is necessary to regularly maintain the BOX TYPE BITZER CONDENSING UNIT.
The condensers used in BOX TYPE BITZER CONDENSING UNIT are mainly air-cooled condensers and water-cooled condensers. According to the type of condenser to clean, the way to clean scale is also different. Here are two commonly used condenser maintenance:
1. The air-cooled condenser uses air as the cooling medium. Since there is often dust in the air, some of the dust will stick to the outer surface of the condenser fins. After a long time, the cooling effect of the condenser will deteriorate. Especially in places where the environment is relatively harsh, it should be cleaned regularly. The cleaning method is: pure dust can be blown clean with compressor air, etc. If there is a lot of dirt, non-corrosive cleaning agent should be used to clean the heat pipe and fins to improve the heat dissipation 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 can be cleaned at least once a year; if the water quality is good, it can be cleaned once every 2 to 3 years.
BOX TYPE BITZER CONDENSING UNIT is equipped with a casing type water-cooled condenser, which can be pickled. The specific operation method is as follows: remove the condenser, release the accumulated water, and then inject 10% dilute sulfuric acid solution into the valve until there is a position where the solution flows out of the water outlet. Dilute sulfuric acid can be released after staying in the condenser for 20~30min. Repeat this two or three times. After Z, install the connecting pipe between the cooling water pipe and the condenser. Open the cooling water valve and rinse for 10~20min. The anti-scaling and cleaning work is over. .
BOX TYPE BITZER CONDENSING UNIT Explanation of the heat transfer process of the condenser of the four major components: We often talk about the refrigeration heat exchanger of the chiller, mainly referring to the condenser and the evaporator, which are two of the four major refrigeration components. Affects the ability and efficiency of the system to absorb and release heat. Both the condenser and the evaporator involve phase change heat transfer, which is a major feature of these two refrigeration heat exchangers. In addition, there are intercoolers, subcoolers, etc. in some refrigeration systems, the principle of which is similar to that of general heat exchangers.
