6-11 A refrigeration plant that operates on the cycle shown in Fig. 6-23 serves as a water chiller. Data on the indivldual components are as follows: 30,600 W/K evaporator condenser (6.8 kg/s 7.6 kg/s evaporator condenser UA = Rate of water flow = | 26,500 W/K The refrigeration capacity of the compressor as a function of the evaporating and condensing temperatures & e and 1C, respectively, is given by the equation developed in Prob. 4-9 de, kW = 239.5 + 10.073te - 0.1091 - 3.41te - 0.00250 - 0.2030fc + 0.00820te + 0.0013fef -0.00008000st2r2 The compression power is expressed by the equation P, kW = -2.634- 0.3081te - 0.00301/ + 1.066f- 0.005281 - 0.0011lete - 0.00030612t, + 0.000567tet + 0.0000031r21 The condenser must reject the energy added in both the evaporator and the compressor.
