Document Summary

The thermodynamic properties of tetrafluoroethane can be found in the book (table 9. 1 and fig. g. 2). 9. 1 in book) with tetrafluoroethane as the refrigerant. What can you say about the effect of condensation temperature on the coefficient of performance? (a) assume isentropic compression of the vapor (b) assume a compressor efficiency of 75% The thermodynamic properties of tetrafluoroethane are given in book (table 9. l and fig g. 2: (optional) a heat pump is used to heat a house in the winter and to cool it in the summer. During the winter, the outside air serves as the low temperature heat source, while during the summer, it acts as a high temperature heat sink. The heat transfer rate through the walls and the roof of the house is assumed to be 0. 75 kj/s for each c of temperature difference between the inside and outside of the house, summer and winter. The heat pump motor is rated at 1. 5 kw.
