A heat pump is installed in a building to heat the space to a constant 22 ⁰C when the outdoor temperature is 15 ⁰C. 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 ⁰C higher than the desired space temperature, and the saturation temperature of the refrigerant in the outdoor unit is typically 20 ⁰C lower than the outdoor temperature. (one of those coils is the condenser, the other is the evaporator) Determine the states at points 1 through 4.
