Apparatus 2 for providing three separate functions of heating (winter mode), cooling (summer mode), and simultaneous heating and cooling (autumn and spring mode). The apparatus comprises a heat pump section 4 for providing the heating, a chiller section 6 for providing the cooling, and a balancing section 8 for providing heating or cooling. The apparatus being such that the chiller is connected to the heat pump whereby the chiller is able to expel heat to the heat pump to provide cooling; the heat pump is connected to the chiller whereby the heat pump is able to obtain heat from the chiller to provide heating; the chiller is connected to the balancing section whereby when heat is not required to be expelled by the chiller to the heat pump then heat is able to be expelled by the chiller to the balancing section with the balancing section then acting as a heat sink; the heat pump is connected to the balancing section whereby when the heat pump requires heat to provide the heating and the heat is not available from the chiller, the heat pump is able to draw heat from the balancing section then acting as a heat source. |
