Solar-system house

Abstract

A solar system house having a solar-heat collecting portion on a roof, a solar-heat collecting duct communicated with the solar-heat collecting portion; and a handling box connected to the solar-heat collecting portion. The handling box includes a back-flow damper that prevent a back-flow toward the solar-heat collecting duct, an air-flow change damper that allow selection between a descending duct and an exhaust duct opened to the outside, a solar-heat collecting fan positioned between the back-flow chamber and the air-flow change damper, and a driving motor for rotating the solar-heat collecting fan in the handling box, which is a direct current (DC) motor to be driven by a solar-battery and a rechargeable battery electrically connected to the solar-battery.

What is claimed is:  
     
         1 . A solar system house, comprising: 
 a solar-heat collecting portion on a roof; a solar-heat collecting duct communicated with the solar-heat collecting portion; and a handling box connected to the solar-heat collecting portion, wherein    the handling box includes a back-flow damper that prevent a back-flow toward the solar-heat collecting duct, an air-flow change damper that allow selection between a descending duct and an exhaust duct opened to the outside, a solar-heat collecting fan positioned between the back-flow chamber and the air-flow change damper, and a driving motor for rotating the solar-heat collecting fan in the handling box, which is a direct current (DC) motor to be driven by a solar-battery and a rechargeable battery electrically connected to the solar-battery.    
     
     
         2 . The solar system house as claimed in  claim 1 , wherein 
 the solar-heat collecting portion is constructed of: a roof plate including a steel roof plate, an amorphous silicon solar battery layered on the steel roof plate, and a resin coat applied on the amorphous silicon solar battery; and    an air flow path having a roof pitch formed immediately bellow the roof plate.    
     
     
         3 . The solar system house as claimed in  claim 1 , wherein 
 an exhausting operation is performed during the daytime, where the air-flow change damper is communicated with the exhaust duct to perform the exhausting operation, and    a radiational cooling is performed during the nighttime, where the air-flow change damper is communicated with the descending duct to introduce air into a room.    
     
     
         4 . The solar system house as claimed in  claim 1 , wherein 
 driving motors used for activating the back-flow damper and the air-flow change damper are DC motors that are connected to the rechargeable battery as a power supply.    
     
     
         5 . The solar system house as claimed in  claim 1 , further comprising: 
 a thermal sensor provided on a solar-heating duct, wherein    the driving motor of the solar-heat collecting fan is turned on/off and the back-flow damper is opened/closed, based on a temperature detected by the thermal sensor.    
     
     
         6 . The solar system house as claimed in  claim 1 , wherein 
 the solar-heat collecting duct is a ridge duct that is placed inside of a house.    
     
     
         7 . The solar system house as claimed in  claim 1 , wherein 
 the solar-heat collecting duct is a ridge duct that is placed outside of a house.    
     
     
         8 . The solar system house as claimed in  claim 1 , wherein 
 a lower end of the descending duct is opened to an under-floor air-circulating space communicating with an interior of a room through an outlet formed on a predetermined location.    
     
     
         9 . The solar system house as claimed in  claim 8 , wherein 
 an under-floor air-circulating space is a space between a solar-heat accumulating dirt-floor concrete and a floor plate.    
     
     
         10 . The solar system house as claimed in  claim 1 , wherein 
 a lower end of the descending duct is directly opened to an under-floor air-circulating space.    
     
     
         11 . The solar system house as claimed in  claim 1 , wherein 
 a lower end of the descending duct is opened to an under-floor air-circulating space and directly opened to an interior of a room.
