Effect of Various Parameters on Working Condition of Chiller

The present work aims to find out the effect of various parameters on evaporator, compressor and condenser in vapour compression cycle using “high performance tube manufacturer's software” for evaporator and condenser and using “compressor selection software of a reputed manufacturer” for compressor. The present work includes the effect of number of tubes, number of passes and fouling factor on saturated refrigerant temperature (SST), tube side velocity, pressure drop and temperature approach in evaporator and condenser. Effect of SST on power input to compressor, cooling capacity, condenser capacity and coefficient of performance (COP) and also effect of condensing temperature on power input to compressor, cooling capacity and condenser capacity is studied using software.
