A heat pump is installed in a building to heat the space to a constant 22 °C when the outdoor temperature is 15 °C. The heating requirement at these conditions is 30 kW. The system uses R-410a as a refrigerant and operates according to an ideal vapor compression cycle as shown in the figures below. The saturation temperature of the refrigerant in the indoor coil is typically 20 °C higher than the desired space temperature, and the saturation temperature of the refrigerant in the outdoor unit is typically 20 °C lower than the outdoor temperature. (one of those coils is the condenser, the other is the evaporator...you should be able to identify which one is positioned outside and which one is inside for this application)
