Life of Montana Insurance Company solar system. Final report
A solar heating system for a 3-story office building in Montana is described. The system consists of a total area of 4410 square feet of hydronic flat-plate collectors employing a 50% solution of ethylene glycol and water, two 3000 gallon pressure storage tanks, an intermediate heat exchanger, and a differential controller with one sensor in the collector discharge manifold and one in the storage system. An acceptance test is described which consisted of monitoring collector, heat exchanger and storage temperatures under varying collector loop and storage loop flow conditions to determine the effect of these parameters on the system performance. The performance of the system was estimated on the basis of an f-chart analysis. Installation photographs and as-built drawings are included. (LEW)
