A heat exchange system comprises a heat exchanger and thermal storage device 3 arranged to extract the heat generated by a cooling operation 1, such as a refrigeration system. The heat exchanger and thermal storage device are connected to at least one heat utilising device 5, where the heat extracted from the cooling operation is supplied to the heat utilising device. A heat dump 2 may be provided to release heat to the atmosphere. If insufficient heat is generated by the cooling operation, a heat pump (4, fig.3) may be used to provide the additional heat energy required. The heat utilising device may involve underfloor heating, central heating or hot water supply. Preferably, the heat utilising device is a heated seat, where the seat has means for enabling heated fluid to be circulated below the seating surface. The system is preferably used to provide heating for bar and restaurant outdoor areas such as smoking areas, and alfresco dining areas for drinking and eating and outside. Alternatively, the heat extracted from the cooling operation may be supplied to a heat engine (6, fig.4) to drive a mechanical appliance (7, fig.4), such as a generator (8, fig.5), which may power an electrical appliance (9, fig.5). |
