Question

A heat pump will be used to heat a building where the average outside temperature is -1 degrees. There is a constant 80000 kJ / h heat loss from the building and it is desired that the building interior temperature is 20 degrees. The minimum power requirement of the heat pump operating according to the Reverse Carnot cycle is 10 kilowatts. According to this;

    a) Find the heating effect coefficient of the heat pump.

    b) Since the unit price of electricity is 0.8 Tl / kWh, what is the electricity cost in heating this building with a heat pump?

    c) What would the heating cost be if the building's heat requirement was met with electric heaters?

    d) What system do you prefer for the heating process? Why is that?
