논문 초록 (Abstract)
An office heating system is intermittently operated according to general occupancy patterns. When the heating system is not operated, heating load is accumulated in an indoor space, causing an decrease in an indoor air temperature. Because of this phenomenon, recovery times required when the heating system is restarted. The recovery time is affected by the heating system capacity and restart time. An excessive capacity causes increase in the recovery time and an insufficient capacity causes increase in an installation cost. Also, if the heating system restart time is set late, it may cause an worsening of the indoor thermal environment. Conversely, if the restart time is set early, it may cause unnecessary energy usage. Therefore, determining an optimal capacity and restart time is important, so this study evaluate the recovery time and energy usage according to various heating system capacities and restart times. To achieve this, an energy simulation was implemented using EnergyPlus with varying the heating system capacity and restart time. As a result, the recovery time varied between 46 379min. and daily energy consumption varied between 636.0, 879.7kWh with various heating system capacities. The recovery time varied between 53 118min. and daily energy consumption varied 675.4 869.8kWh with various heating system restart times.
