Lightbulb heat pump problem

The heat pump operates on freon 134a and follows a standard Carnot cycle. The condenser delivering heat to the room is supplied with saturated vapour at 30 ○C that is condensed to give saturated liquid also at 30C.
Assuming the air temperature is an average 15 C for a refrigerant flow of 0.02kg/s, calculate:


a) heat deliver in the room


calculations done


increment of Q2=e X INCREMENT OF P= 0.02(30-15)=0.3 joules
