Outline of Final Research Achievements

To predict seasonal variations of heat source temperatures in reservoir source heat pump (RSHP) systems, we proposed a macro simulation model in which vertical and horizontal mixtures because of natural convection by heat release during RSHP operations are considered as well as heat transfer. Using this simulation model, we examined effective operation schedule for energy savings.
