![]() ![]() Pressure and temperature of the refrigerant must be higher than the condensing temperature. The result of the temperature increase is superheat. The process of compression, through mass flow, raises the temperature and pressure of the refrigerant. The compressor’s out put is equally only to its intake because the mass flow must be equal. The mass flow rate produced by a compressor is equal to the mass of the suction gas pulled in by the compressor. ![]() Of the six, the reciprocating and scroll compressors are the two most frequently found in a residential air conditioning system. The act of compression is performed by any one of the following six types of compressors: a reciprocating piston, rotary, scroll, screw, centrifugal, and sonic compressors. The compressor pulls the refrigerant out of the evaporator and pushes it though a condenser. If the suction gas is not superheated, the compressor can be damaged. The Compressor compresses a low-pressure superheated gas into a high-pressure superheated gas. These four components are divided into sections and explained in depth as follows. The four main components of the refrigeration cycle include: To understand why this is, it requires an understanding of the physical properties of the refrigeration cycle. A fixed orifice is charged to the superheat of the suction line leaving the evaporator. A Thermostatic Expansion Valve (TXV) is charged to the sub-cooling of the liquid line leaving the condenser. Different types of metering devices have different ways of charging. ![]()
