AB - R410A is one of the HFC refrigerants, which are preferred globally to promote the most environmentally friendly option on the basis of an objective reference system taking into account the alternative selection of HCFC refrigerants for the air-conditioning system by the Kyoto protocol. This article presents a three-dimensional (3D) rotary compressor that is within the family of rotary compressors. First, the geometry of the compressor is explained and equations relating the volume of the compression and suction chambers to the rotational angle of the shaft are derived. These equations are used within a model that predicts the mass flow rate, power consumption, and cooling capacity of the compressor. The model includes energy and mass balances within the compression chambers, as well as the estimation of leakage, frictional, and electrical losses. The primary sources of energy and flow losses are identified for this type of compressor. The results presented were generated using refrigerant R410A as the working fluid based on the properties of the ‘Ref-prop 7.0’ program provided by NIST. Due to the two compression chambers vertically separated in one cylinder, this 3D rotary compressor has the best vibration characteristic and the smallest torque variation among the conventional-type compressors.
