Problem 15. A heat pump is used to maintain a warm area at 30 degC by transferring heat from surroundings at-20 degC. The heat pump is assumed to operate as an Ideal Vapor Compression Cycle Cycle Conditions TH= 30-degC TL--20-degC T1 30-degC h- 241.8 kJ-kg T2 T3-20degC h 386.8 kJ-kg S 1.7422 kJ.kg K h 423.1.kJ.kg T,-37.8-degC A. Determine that heat rejected (in kJ/kg) by the refrigerant in the condenser Condenser Compressor Expansion Valve Evaporator COMP Assume p4 - p1...

Design of a Solar Thermal Power Plant The scheme of the solar thermal power plant is depicted in Figure 1. It features a Rankine-cycle based solar thermal power plant using tower technology. Technical data and assumptions: • = net electrical power output (turbine - pump) = 12 MW • Working fluid: water. • Condenser: outlet temperature = 320 K, outlet steam quality = 0%; no pressure drop through condenser. • Pump: adiabatic, outlet pressure = 170 bar; outlet temperature =...
