In a compression refrigeration system, where is the strainer typically placed?

In a compression refrigeration system, placing the strainer between the compressor and the evaporator is crucial for ensuring the longevity and efficiency of the system. The function of the strainer is to remove any debris or contaminants that might enter the refrigeration cycle. These impurities can originate from various sources, such as wear from moving parts within the system, dust, or debris from maintenance activities.

By installing the strainer in this location, it protects the evaporator and the compressor from potential damage caused by these particles. The compressor is particularly sensitive to contamination; debris can cause wear and tear on internal components, leading to reduced efficiency or even failure of the system. The strainer helps to ensure that only clean refrigerant enters the evaporator, where it absorbs heat.

Additionally, keeping contaminants out of the evaporator is essential for maintaining proper heat exchange, which directly affects the performance of the refrigeration system. Hence, the placement of the strainer between the compressor and the evaporator is strategic, ensuring that the critical components are safeguarded, and the system functions effectively.
