Refrigerant 134a enters the compressor of a vapor-compression heat pump at 15 lbf/in.2, 0°F and is compressed adiabatically to 160 lbf/in.2, 160°F. Liquid enters the expansion valve at 160 lbf/in.2, 95°F. At the valve exit, the pressure is 15 lbf/in.2 The heat pump receives energy from the cold thermal reservoir at a rate of 100Btu/hr. Draw the T–s diagram for the cycle and determine:
a. The mass flow rate in lb/hr
b. The net amount of heat transfer delivered to the hot reservoir in Btu/hr
c. The coefficient of performance.
