<p><P>PROBLEM TO BE SOLVED: To improve energy comversion efficiency by more than double by acquiring heat simultaneously with electric power to solve disadvantage in practical use, in comparison with an energy device using petroleum and a gas in view points of installation space, energy unit price and the like, as energy conversion efficiency of photovoltaic power generating cell is about 15% present, and the total necessary light receiving area is large at any installation site. <P>SOLUTION: With respect to the power generating cell of a device getting and utilizing the solar energy, a heat pump outputting electric power and heat with high energy conversion efficiency by cogeneration, directly receiving the output of the heat constantly changed, and efficiently converting the same into the heat of a temperature and heat quantity necessary for a demander, is developed and systemized as a whole, thus a necessary light receiving area per an acquired energy unit and unit price can be reduced by half, investment effect of the solar device can be increased, and the spread of the device can be accelerated. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
