This paper suggests the real-time optimal control method of central air-conditioning system using chilled water. The control variables for optimization are differential pressure of the pump and the supply chilled water temperature supplied to the air conditioning system produced from the central chiller. The optimal control variables of the control point are calculated using genetic algorithm in one-hour time step. The objective function of algorithm was the energy consumption of the HVAC system, and the energy consumption was calculated using the mathematical model. The results of the operation of the normal mode under the initial design conditions and the optimal operation mode with the optimal control variables were evaluated by comparing the energy consumption of the HVAC system with the variation of the control volume at the control point selected in this study. As a result, the chilled water supply temperature of the chilled water loop was operated by changing between approximately 9℃ and the differential pressure of the pump between 34.87 ㎪ and 78.91 kPa for the optimal control method. The total energy consumption of the HVAC system during optimal control operation was reduced by 16.98% compared to operation of the normal mode.

The purpose of this study is to analyze the energy saving effect when the Independent Room Control Ventilation system is applied in residential buildings. Based on statistical data, the occupants schedule was prepared and converted into a ventilation schedule for each room. Energy Plus was used to analyze energy consumption. As a result, compared to the continuous ventilation system operated at 0.5ACH when operating with individual room control ventilation system, annual heating energy was saved 11.6% and annual cooling energy was saved 3.4%. Carbon emissions were reduced by 13.7%.
