Abstract

An analysis of high pressure ratio scroll compressors and the influences of built-in volume ratios and a dynamic discharge valve on compressor performance was conducted. The analysis includes throttling flow losses, over- and under-compression losses, and clearance volume re-expansion losses. The effects of the variable area of the discharge port opening throughout the compression cycle, valve losses, and additional compressibility effects are included. These effects is evaluated over range of saturated evaporator and condenser conditions. The scroll compressors for high pressure ratio application benefit from a discharge valve.
