INDOOR AIR TEMPERATURE AND HUMIDITY FLUCTUATION UNDER OPTIMAL OPERATION OF HEAT SOURCE SYSTEM AND EFFECT OF SYSTEM COMPOSITION ON THE OPTIMIZATION RESULTS : Fundamental study on hybrid energy source system with thermal storage tank of middle scale office building on a summer day

Abstract

The purpose of this paper is to clarify the following two points. First point is the indoor air temperature and humidity fluctuation under an optimal operation of heat source system. Second is the effect of the system composition (heat source equipment capacity ratio) on the optimization results. Method for the optimization is applied to the hybrid energy source system with thermal storage tank of a middle scale office building on a certain summer day. The results are as follows : 1) the suitable change of the room temperature is calculated automatically by optimization process, so there is possibility of realizing effective energy conservation etc. by more active control of the temperature, 2) the relation between heat source equipment capacity and building heat load influences its suitable ratio, and the ratio influences the achievement degree of the optimal operation effect considerably. 3) according to a trial calculation, it is surmised that the system with a few heat source equipment using various energy is advantageous for pursuing energy conservation etc.
