Title: Multi-mode solar heat recovery device

Patent ·
OSTI ID:5513286

A multi-mode solar heat recovery device for use at an interior surface of a window is described. The device includes heat conductive plates for heat absorption of sunlight, reflected from corresponding light reflective surfaces. Each heat conductive plate includes heat conductive tubing and carrier fluid to convey the heat from the plate to a point of heat utilization, such as a water heater or space heater. Regulation of the heat recovery device is provided by automatic adjustment of the light reflective surfaces to variable orientations with respect to the incident sunlight and heat conductive plates. This variable orientation permits selection of essentially complete light blockage when adjusted to a closed position, maximum light reflection to a heat absorbing surface when at an intermediate position and unobstructed transmittance of light when in a fully opened position. The heat recovery device is further adapted with a convection heat collector which may be utilized as a cooling device. The solar heat recovery device and convection heat collector may also be used collectively as part of an overall temperature control system which includes two water storage tanks which permit two temperature level heat recovery and heat utilization. Furthermore, this system can be adapted for full environmental control with an evaporative and radiant cooling system to complement the heat recovery system.
