The schematic lay-out of the solar heating system as it is modelled is given in Fig. 1. It consists of the following components: • 7000 m2 of non-selective flat plate collectors. These collectors are characterized by an optical efficiency of.75 and an overall heatloss coefficient of 5.0 (W/ui2k). • seasonal heat storage of 50,000 m3 […]

D. van Hattera Т» Vavasorl Joint Research CenterIspra Establishment May, 1983 CEC MINSUN APPLICATION CASE STUDY Case Description This study deals with the application of the MINSUN program for the analysis of an active solar space heating system for a large building complex. It does not pretend to be an in-depth analysis of solar systems […]

The Canadian Application Case Study does not model a system which has been, or ever will be, built. This means that the values chosen for input parameters are not critical and, more importantly, that the specific MINSUN results are not definitive. However, the exercise did produce many important and useful benefits. Though specific results are […]

The reference case was chosen early in this study only as a starting point from which to conduct sensitivity analyses and as a base for comparison of system configuration. It displays an adequate solar fraction and annual cost but, as was determined, is not an "optimum" system, though. it is representative of the various configurations […]

After a series of single point evaluations a "reference case" was decided upon which combined a local minimum average annual cost with an acceptable solar fraction. This point was: • collector area 100,000m2 • storage volume 2,500,000m^ which had results: • average annual cost 8.01 M $ • solar fraction 63.4% • specific cost $0.07/kWh. […]

Input data values are those recommended by the appropriate THA task experts, except where specific to the Canadian Case Study. There were a number of problems encountered in the use of the MINSUN program. The volume of storage required by the Canadian Case Study left duct storage the only practical alternative. Unfortunately the MINSUN duct […]

The Canadian Case Study system is shown schematically in Figure 1. Solar energy is collected in a single central receiver array of approximately 100,0 m^. The collector array is connected through 2000 m of pipe to a nearby duct storage system of approximately 2,500,000 m^. Heat capacity of storage is 2.16 MJ/m^K. The load of […]
