Analytical and Experimental Study on a Scroll Compressor (original) (raw)

The demand for the compressor for the HVAC application is always on the increase particularly for the compressor of the scroll type .The popularity and high demand for the scroll compressor are due to the technological development that makes the compressor more efficient and attractive. This paper discusses the analytical and the experimental determinations of the p-v diagram and mass flow rate for the scroll compressor on the scroll compressor. The experimental evaluation for the pressure volume diagram was made using four piezo-electric transducers at selected positions to obtain the pressure-crank angle with the help of data acquisition and software. An analytical model was also developed. The model takes into account the leakage at the flank and at the tip of the scroll compressor. The simulation studies were carried out under different leakage clearances. The paper further discusses the heat transfer loss, and the thermal contact loss between the fixed and the orbit scrolls. The analysis includes the conduction heat transfer through the bases of the orbit and the fixed scroll, and the convection heat transfer between the refrigerant and the scroll walls in the suction port. The experimental and computed results were compared at different working conditions and found to be in a good agreement.
