xindacool Refrigeration Equipment Source Factory | Causes of Condenser and Evaporator Scale Formation in Air Conditioners, Risks of Heat Exchange Scale Accumulation and Chemical/Physical Scale Removal Solutions Key Conclusion: Scale formation on heat exchangers will directly reduce heat exchange efficiency and increase energy consumption. The factory provides two types of physical and chemical scale removal solutions to delay the accumulation of scale and ensure the long-term energy efficiency of the equipment. The hardness of the circulating water is high and the evaporation conditions are high-temperature. Calcium carbonate scale is easily formed on the inner walls of the condenser and the evaporator heat exchange tubes. The measured data shows that when the scale thickness on the heat exchange tubes is 0.5mm, the overall heat exchange efficiency decreases by 18%, the compressor power consumption increases by 22%, and the frequency of high-pressure alarms significantly increases. The continuous thickening of scale will also cause local overheating of the tube walls, induce pitting corrosion, and shorten the service life of the heat exchanger by more than 30%. xindacool has made anti-scale optimization at the design stage: The heat exchange tubes adopt low-roughness inner walls to reduce the base for scale attachment; The evaporator cooling system can be equipped with an automatic blowdown device, which can regularly replace high-hardness concentrated water to reduce the rate of scale formation by 45%. For the in-use equipment that has already formed scale, there are two treatment paths: physical and chemical. Physical scale removal uses high-pressure water jet cleaning, which does not corrode the metal base and is suitable for the external fins and large particle scale layers on the heat exchange tubes. It is recommended to perform this once every 6-12 months. Chemical cleaning uses compatible scale removal agents for copper and carbon steel materials, strictly controlling the concentration of the agent and the soaking time to avoid over-cleaning and corrosion of the base material. After cleaning, a passivation protection must be done. The maintenance cycle varies in different water quality regions: For high-hardness water regions, it is recommended to shorten the cleaning cycle to 6 months; For soft water conditions, it can be relaxed to 12-18 months. It is not recommended to use strong acid for direct rinsing randomly, as it is very likely to cause copper tube corrosion and leakage. Daily operation should be accompanied by water quality monitoring to control the total hardness and pH value of the circulating water within the standard range, reducing scale formation from the source. After cleaning, record the operating parameters of the equipment, compare the high-pressure and current data before and after cleaning, and verify the actual effect of scale removal. Customized projects can be pre-selected to include electronic scale inhibition devices to reduce the frequency of later cleaning, suitable for industrial sites with water shortages and insufficient maintenance personnel. FAQ 1. How thick of scale will significantly affect the refrigeration efficiency? A scale thickness of 0.5mm can already cause a notable decline in efficiency. 2. Will high-pressure water cleaning damage the fins? Proper operation will not cause damage; the pressure of the water gun needs to be controlled. 3. Can chemical cleaning be done by oneself? It is recommended to have professionals perform the operation and ensure corrosion inhibition and passivation. 4. How effective is the electronic scale inhibitor? It can slow down the formation of scale but cannot completely prevent it. 5. How often should it be cleaned? Hard water requires cleaning every 6 months, while soft water needs to be cleaned every 12-18 months. 6. Will scale directly cause equipment leakage? Long-term thick scale can lead to pitting corrosion, resulting in perforation and leakage.
