Modify the cycle in Problem 10.9 to have an isentropic compressor efficiency of 83% and let the temperature of the liquid leaving the condenser be 100 F. Sketch the T-s diagram for the modified cycle and determine, for the modified cycle, (a) the compressor power, in horsepower. (b) the rate of heat transfer from the working fluid passing through the condenser, in Btu/min. (c) the coefficient of performance. Note: Problem 10-9 is a vapor-compression system of R134a with a mass flow rate of 30.59 lb/min.
Ideal vapor-compression refrigeration cycle functions at steady state. Working fluid is Refrigerant 134a. Saturated vapor enters compressor at 1.70 bar. Saturated liquid leaves condenser at 7 bar. Refrigerant has mass flow rate = 7.9 kg/min DETERMINE: 1. What is power of compressor in Watt? 2. What is coefficient of performance? 3. What is refrigerating capacity in tons?
An ammonia-water absorption refrigeration cycle is used to keep a space at -5 C when the ambient temperature is 20 C. Pure ammonia enters the condenser at 20 bar and 60 C at a rate of 0.02 kg/s. Ammonia leaves the condenser as a saturated liquid and is expanded to 2 bar. Ammonia leaves the evaporator as a saturated vapor. Heat is supplied to the generator by geothermal liquid water that enters at 100 C at a rate of 0.25 kg/s and leaves at 70 C. Determine (a) the cooling capacity (in TR) and (b) COP of the system. The enthalpies of ammonia at various states of the system are: condenser inlet h2 = 1510 kJ/kg, evaporator inlet h4 = 418 kJ/kg, evaporator exit h1 = 1420 kJ/kg. Take the specific heat of geothermal water to be 4.18 kJ/kg-K
