Photovoltaic and solar thermal co-generation storage wall module and heat-pump system

Abstract

A wall module used to retrofit any existing building into solar building or construct new solar building is made of a hybrid photovoltaic and solar thermal plate, a heat pipe, a solid thermal energy storage, a glass cover, and a heat-pump system. When the incident sunlight penetrating through the transparent glass cover reaches to the cogeneration plate, portion of it is converted into electricity and the rest becomes into heat; then the heat is transferred back to the solid thermal storage; when it is needed for heating and cooling, the stored heat is retrieved and transported to its destination with heat pump system; during the transportation process, the temperature of the stored heat is boosted up. Any buildings, no matter existing building or new building, can be converted into a large scale solar power generation and storage station using the wall modules of present invention without changing their structures and functions. As the buildings share the insulation with the wall modules, the addition of the wall modules will significantly improve the encapsulation of the buildings. The wall modules change the whole body of building into large scale storage without occupying the interior space of the building.

I claim: 
     
         1 . An assembly is consists of a cogeneration plate, which is a metal plate laminated with solar cells, solid thermal energy storage media, heat pipe, circulation coils of heat-pump system, insulation layers and glass cover, where the heat pipe is welded on the metal plate of the cogeneration plate, the glass cover is installed in front of the cogeneration plate leaving a air space, the cogeneration plate is isolated with the thermal energy storage media by the front insulation layer of the storage, and the heat pipe penetrates through the front insulation layer into the storage, the storage is isolated with the outside by the back insulation layer of the storage, the circulation coil of the heat pump system is inserted into the thermal storage media and connected to the heat-pump system; wherein the incident sunlight penetrating through the glass cover and reaching to the cogeneration plate will be partially converted into electricity by the solar cells laminated on the metal plate and rest of it will be converted into heat and collected by the metal plate, then transferred into the thermal storage by the heat pipe welded on the metal plate, when needed, the stored heat will be retrieved by the heat pump system via the circulation coil, mean while, the temperature of the stored heat will be also boosted up. 
     
     
         2 . The cogeneration plate and heat pipe combination of  claim 1  could be encapsulated into a vacuum pipe and have the heat pipe penetrate through the front insulation into the storage of the  claim 1  to avoid glass cover of the  claim 1 . 
     
     
         3 . The circulation coil of heat pump system of the  claim 1  could be directly welded on the metal plate of the cogeneration plate of the  claim 1  to avoid the heat pipe and the cogeneration plate could directly touch to the thermal storage media of the  claim 1  to avoid the front insulation of the thermal storage of the  claim 1 .
