<p>The system uses heat pump technology and a phasechange thermal storage tank to supply space heating, space cooling, and domestic hot water to a building. A heat exchanger in the exhaust air stream and another one attached to the building grey water drain pipe extract heat from the stale air and grey water for delivery to the thermal storage tank. Subsequently, this heat is extracted from the thermal storage tank to supply the evaporator in the heat pump when a heating demand occurs, to supply hot water for occupant use and space heating when required. The system, in a single package, physically and thermally integrates space heating and cooling, ventilation, and hot water supply. Cooling is supplied via a chilled liquid loop circulating via the thermal storage tank. Heating/cooling is supplied via a fan coil while a smaller fan coil exhausts continuously to outside, providing central ventilation from kitchens and bathrooms.</p> |
