Where is the scale trap located in a refrigerating system?

In a refrigerating system, the scale trap is situated between the compressor and the evaporator. Its primary function is to prevent the accumulation of unwanted substances, such as scale and dirt, that can affect the efficiency and functionality of the system. By being located in this position, the scale trap effectively captures these impurities before they can reach the evaporator, which is critical for maintaining optimal heat transfer and refrigeration performance. Ensuring that the refrigerant entering the evaporator is clean helps to avoid blockages and operational issues that could arise from debris or scale buildup. This placement is essential for prolonging the life of the system and ensuring efficient operation.
