Simulation of heating/cooling load using dest program & measurement of HSPF & SEER for geo-space heating system

Using DeST Program, Simulation of Space Heating/cooling Load of two buildings has been conducted for Geo-Space Heating System using Gradient Utilization Techno- logy in university campus. Simulations were conducted in accordance with the different conditions: Temperatures & RH of Rooms, different sources of Weather Data, intensity of persons, Timetable of operation & Equipment, building constructions. Also measurement has been conducted using the measurement system. Then the comparisons between simulation & measurement were made. The range values of (HPF)_{Sys .h} was 3-13, average value was 6-9 based per hour; The values of (HPF)_Sys.d & (EER)_{Sys .d} could be obtained through the comparison between measurement & simulation. (HPF)_Sys.d values were obtained around 4~7,and (HSPF)_Sys was around 5-6 for winter 2005-2006 & 2006-2007. In 2006 summer, consumption of electrical energy was obtained; (EER)_Sys.d values based on per day was 2.5~5.3 .In accordance with the analysis of (HPF)_{Sys .d} & (EER)_{Sys .d}, the lower data always appeared in the periods of non-peak & lower load. It tells us where the potential of energy saving will be. The researchers noticed the quite difference between the simulation &  measurement& & try to search the reasons. More efforts & more suggestions will be made for increasing the values of HSPF)_Sys & (SEER) )_Sys of the systems.
