The low pressure vapor from suction line is drawn into the opening and fills the space behind the blade as it revolves. The final type of AC compressor is the centrifugal compressor. In a single system, the blades can vary in number from anywhere between two to eight. On a properly functioning compressor, the mass flow rate (amount of refrigerant moving through the compressor) and the suction gas temperature are the primary factors that impact compressor discharge temperature. Scroll compressors are becoming more popular for use in HVAC systems as they are more reliable and efficient than reciprocating types. The external-drive compressor has a crankshaft that is driven by a pulley and belt system.An electric motor can also be used to drive it directly.
