What is the principle of the chiller? How to maintain it?
Speaking of chillers, it is not a device that specializes in producing cold water, but a device to cool other equipment. Cold water is just a means for it to cool down.
The principle is to inject a certain amount of water into the water tank in the machine, cool the water through the refrigeration system of the chiller, and then deliver the low-temperature cooling water to the equipment that needs cooling through the pump. The chilled water of the chiller takes away the heat increase, and then returns to the water tank to achieve the cooling effect.
Although the chiller is not a direct production equipment, it has also played a significant role in promoting the development of the industry. Many industrial production methods require cooling equipment, and the chiller has played a good role. In the process of using, we should also pay attention to maintenance to effectively extend its service life.
1. The parts of the chiller should be checked frequently, including voltage, flow, and compressor. The normal value is 308V, and the current is between 11A-15A. If it exceeds or falls below this range, it should be sensitive. Considering whether there is a malfunction, it should be checked in time.
2. Leakage is a big problem, which will exist in most mechanical equipment, especially after a period of use, and it is no exception in chillers. Our country is in a temperate zone, with four distinct seasons throughout the year. According to the temperature changes in different seasons, the pressure display of the chiller is also different. In normal work, the general high pressure display 11-17KG, low pressure display 3-5KG.
3. Frequently check the heat dissipation system, including cooling tower fans, nozzles, etc. In addition to heat dissipation, the inspection items should also pay attention to the water supply in the chassis.
4. During use, the chiller does not need to be cleaned every month. It is enough to clean the system after half a year of use. Once a year, the objects to be cleaned include cooling towers, radiator pipes and condenser parts, etc., to ensure more Good cooling effect.
5. When it is not used for a long time, the related circuit switch should be turned off.
Reasonable maintenance can effectively avoid the influence of dirt and other impurities on the refrigeration effect and prolong the service life of the chiller. Of course, although the length of service life is related to maintenance, it is mainly determined by the quality of the product, so when you buy, you also need to look for the quality.
