Abstract
A solar air heating system for circulating heated air from a solar collector or a heat storage unit, or both in proportion to heat available from the collector, through a control chamber to an environmental space to be heated, using one blower sized to optimize flow through the duct system to the space. When the space does not require heat, heated air from the collector is propelled via the chamber to the storage unit by a second blower sized to optimize flow from the control chamber to the storage unit.
Claims6
A solar air heating system comprising a collector and a storage unit for a space to be heated;
- air propulsion and flow control apparatus comprising a chamber having a first port to be communicant with said space, a second port to be communicant with said storage unit and a third port to be communicant with said collector;
- a first propulsion unit and a first flow control valve for flow from said chamber to said space, a second propulsion unit and a second flow control valve for flow from said chamber to said storage unit, a third flow control valve for flow from said collector to said chamber, and a fourth flow control valve for flow from said storage unit to said chamber;
- said first propulsion unit constituting the sole propulsion source for air propelled from said collector and/or said storage unit through said chamber to said space;
- control means for said apparatus (a) for opening said third valve and activating said first propulsion unit for flow from said collector to said chamber to said space, (b) for opening said third valve and activating said second propulsion unit for flow from said collector to said chamber to said storage, (c) for opening said fourth valve and operating said first propulsion unit for flow from said storage to said chamber to said space, and (d) for opening said third valve and said fourth valve and activating said first propulsion unit for flow from said collector to said chamber and from said storage to said chamber for mixing and flow to said space.
