Question:
A heat pump operates on the ideal vaporcompression refrigeration cycle with refrigeranta as the working fluid. The refrigerant evaporates at C and condenses at kPa. The refrigerant absorbs heat from ambient air at C and transfers it to a space at C Determine a the work input and the COP, b the exergy destruction in each component of the cycle and the total exergy destruction in the cycle, c the minimum work input and the secondlaw efficiency of the cycle. d Determine the COP, the minimum power input, the total exergy destruction, and the exergy efficiency of the cycle if a groundsource heat pump is used with a ground temperature of C The evaporating temperature in this case is C Take everything else the same.
