Low pressure vapour enters the compressor where pressure and superheat areincreased. High pressure vapour is passed through the oil separator where compressor oil is removed and recirculated to thecompressor via the oil cooler. The high pressure oil-free vapour is fed to the air cooled condenser coil and fans where the heat isremoved. The subcooled refrigerant then passes through the expansion valve where pressure is reduced and further cooling takesplace before returning to the evaporator.Page H.5Doc. No. PC156/08.04/GB

YAES-SA SAMPLE SELECTION - COOLINGA chiller is required to cool water from 12°C to 7°C having acooling capacity of 690 kW at a design flow rate of 33 l/s. Otherdesign conditions applying are:Ambient air entering condenser: 35°CFouling factor:0.044 m² °C./kWAltitude:Sea levelFrom a cursory examination of Capacity Table 5, a modelYAES0785SA gives approximately the required capacity:Capacity= 705.1 kWCompressor power= 244.1 kWNo correction factors apply therefore, after calculating the flowrate, the conditions will be as follows:Cooling capacity:705.1 kWWater temperature:12°C to 7°C (Range = 5°C)Water flow rate:33.01 I/sCompressor power:244.1 kWAll values are within the operating limits in Table 2.
