ABSTRACT:
With reference to FIG. 3, the sloping roof (250) of a building (10) incorporates inner and outer juxtaposed metal panels, (15, 16) spaced from each other to define passageways (20) which serve as heat exchangers. A closed-loop water circulation system (18) connects the passageway (20) with low, medium and high grade heat store chambers (21, 23, 25) disposed within the building foundation structure (13). The water circulation system (18) employs sub-systems (22, 29 and 31) which comprise, respectively, primary, secondary and tertiary sub-systems. The heat store chamber (21) comprises a portion of the primary circulation sub-system (22) whereby water is re-circulated through the panel passageways (20) so as to be raised in temperature 20 by solar heat. In addition to the heat store chamber (21), the primary sub-system (22) comprises a heat pump unit (27). The secondary water circulation sub-system (29) conveys water in a closed loop which, in addition to the heat store chamber (23), comprises the passageways (20) and the heat pump unit (27). The tertiary water sub-system (31) comprises the heat store chamber (25), radiators (19), underfloor heat exchanger coils (35) and a heat exchanger coil (37) incorporated in a hot water cylinder (39). Heat from water flowing in the primary sub-system (22) is given up to the heat store chamber (21) and also to the heat pump unit (27). Heat from water flowing in the secondary sub-system (29) is given up to the heat store chamber (23), as well as to the heat pump unit (27). A controller (40) is operable to provide controlled transfer of heat between the sub-systems (22, 29, 31).
