ABSTRACT:
Disclosed is a solar powered heat pump useful for both heating and cooling building space and for providing refrigeration. The device operates on a chemical effect (adsorption) intermittent heat pump cycle in which the moderately high temperature heat generated by insolation is used to drive the desorber. The device has inherent thermal storage, can be factory built, sealed, and tested, can be electronically controlled for completely automatic operation, and includes a built-in back-up heater which obviates the need for installation of a separate back-up heating system. It can be manufactured from inexpensive materials such as glass, and implodes rather than explodes on failure.
A preferred embodiment of the device is designed as a modular unit which can readily be combined with others of identical design to produce a solar powered battery panel for heating and cooling. This embodiment preferably comprises a tubular enclosure defining a pair of chambers separated by a valve. A first chamber is packed with silica gel (or an equivalent adsorbent material) arranged such that mass and heat transfer through the gel take place rapidly and in comparable time periods. The first chamber is surrounded by a larger diameter, solar radiation transparent housing and the annular space between the chamber and housing is evacuated. The enclosure is mounted together with a diffuse light reflector which focuses sunlight toward the first chamber. Heat exchangers provide thermal communication between respective chambers and a pair of duct portions adapted for connection to a building heat distribution system.
