What is a Refrigerator Compressor? 

refrigerator compressor diagramThe refrigerator compressor is one of the four main components that makes the refrigerator work. The compressor’s job is to compress and control the flow of refrigerant. The compressor receives low pressure gas from the evaporator and converts it into high pressure gas. As the gas is compressed and the pressure increase, the temperature increases. Which commercial refrigerator do I need?

Refrigerators can have compressors mounted onto the top or the bottom. Top-mounted compressors are best for dry storage areas where the floor can become dusty and covered in spilled ingredients.
