System for reclaiming solar energy in buildings

Abstract

The invention relates to a system for reclaiming solar energy in buildings, comprising a fluid inlet header pipe, a fluid outlet header pipe and a plurality of heat collector panels connected to the two pipes at ends thereof respectively. Fluid with a lower temperature from the fluid inlet header pipe enters into the heat collector panels, where it is heated to a higher temperature by the solar energy stored therein, and then discharges from the system via the fluid outlet header pipe for energy reuse. The heat collector panels are mounted on the inner surface of the cladding panels of the building, so that the outer appearance of the building will not be negatively influenced by the system.

1 . A system for reclaiming solar energy in buildings, comprising a fluid inlet header pipe, a fluid outlet header pipe and a plurality of heat collector panels connected to the two pipes at ends thereof respectively, wherein fluid with a lower temperature from the fluid inlet header pipe enters into the heat collector panels, where it is heated to a higher temperature by the solar energy stored therein, and then discharges from the system via the fluid outlet header pipe for energy reuse. 
     
     
         2 . The system according to  claim 1 , wherein each heat collector panel includes a series of flow passages therein, thus forming a roll-bond heat collector. 
     
     
         3 . The system according to  claim 2 , wherein the heat collector panels are mounted on the inner surface of cladding panel of the building. 
     
     
         4 . The system according to  claim 2 , wherein it further includes a cladding panel, on the inner surface of which the heat collector panels are mounted, and wherein the cladding panel forms part of envelope of the building. 
     
     
         5 . The system according to  claim 4 , wherein the space enclosed by the heat collector panel and the cladding panel is filled with heat conductive materials. 
     
     
         6 . The system according to  claim 4 , wherein the flow passages in the heat collector panels are securely connected to the inner surface of the cladding panel. 
     
     
         7 . The system according to  claim 1 , wherein it further includes an external water pump for maintaining fluid circulation in the system. 
     
     
         8 . The system according to  claim 1 , wherein the quantity of the heat collector panels used in the system is determined by at least one or more of the following factors: desired system capacity, building orientation, system maintainability and extra loading to the building. 
     
     
         9 . The system according to  claim 2 , wherein the flow rate of fluid in the flow passages is determined by the geographical location and the orientation of the building. 
     
     
         10 . The system according to  claim 1 , wherein it is operated at an optimum operation point determined by a survey of solar energy pattern conducted over a certain time for the system.
