Question 2 [26 marks] A refrigeration plant serves as a water chiller. Data on the individual components are as follows: Evaporator: Overall heat transfer coefficient Chilled water flow rate Condenser: Overall heat transfer coefficient Cooling water flow rate Compressor: UA = 30595 W/°C mc = 6.795 kg/s UA = 26375 W/°C mw = 7.55 kg/s TANT The refrigeration capacity and power consumption as functions of evaporating (Te) and condensing (T) temperatures are given by the equations: Qin (kW) = -768 +5.17 - 2Tc Pc(kW)=-0.732T₂ +0.00174672 +0.31Tc If the chilled water and cooling water inlet temperatures are 2 °C and 30 °C respectively, determine: a) Evaporating temperature b) Condensing temperature c) Refrigeration capacity d) Power consumption [20 marks] [2 mark] [2 mark] [2 mark]
