ABSTRACT
On 19 September 1973, the Solar Energy Applications Laboratory of Colorado State University received a grant from the National Science Foundation for the Design, Construction and Testing of a Residential Solar Heating and Cooling System. This chapter aims to detail the design and construction phases of the project. An alternative heating mode utilizes whatever heat is in storage, even at temperatures as low as 27°C, with the auxiliary boiler supplying heat to an auxiliary air heating coil. Determination of the solar collector design factors was accomplished by the use of a University of Wisconsin computer program by which the effects of these collector variables on the percentage load carried by the auxiliary fuel source were determined. For the Colorado State University solar laboratory, the system selected was an Arkla-Servel 3-ton lithium bromide absorption cooling unit modified to utilize hot water as the heat supply to the generator.
