The Impact of Environmental Pollution on the Performance of Water Coils

The Impact of Environmental Pollution on the Performance of Water Coils

Introduction Water coils are essential components in heating, cooling, and air conditioning (HVAC) systems. Their main function is to transfer heat between the fluid circulating inside the coil (usually hot or chilled water) and the air passing over the coil’s surface. However, the efficiency of water coils is heavily influenced by several external factors—one of the most critical being environmental pollution. In this article, we explore how various types of environmental pollutants affect the performance, efficiency, and lifespan of
