What collector area is needed for the system shown to providethe necessary space heating for a home having 2000ft2 offloor area? Assume an average daily insolation of1000Btu/ft2 and an efficiency of 50%. Also assumethat the house requires 50 million Btu per thousand square feet offloor area for the 180 day heating season. What collector area is needed for the system shown to providethe necessary space heating for a home having 2000ft^2 offloor area? Assume an average daily insolation of1000Btu/ft^2 and an efficiency of 50%. Also assumethat the house requires 50 million Btu per thousand square feet offloor area for the 180 day heating season.
Explanation / Answer
Ans. 50*10^6*2000/1000=0.50*1000*A*180 A=1111.111 ft^2 [Ans.]
