| Abstract |
This study was carried out to predict the amount of energy consumed by a ventilator installed in the terminal end of a common duct system. It is in which that the partial load control is generally performed. The air volume rate for the central ventilation system of the kitchen and bathroom of each household in an apartment is exhausted through a common duct system regardless of the position of each household within the complex. This air volume rate should be the same regardless of the location of each household. Since the common duct system is installed vertically, and is installed ventilator in terminal for the effective ventilation. Also, the pressure difference of each household increases with the vertical height. Thereby, the air volume rate exhausted on each household becomes different. KARSE has established a standard for constant static pressure ventilators with a constant flow rate damper in the branch duct of the common duct system. A control strategy for partial load control that can save energy must be considered in ventilation systems with common ducts. This paper compares the energy consumption of two control methods and suggests an energy saving control system. |
