Abstract

Heating and air conditioning system is changing rapidly from the traditional HVAC central supply system tothe individual supply system with electrical heat pump system (EHP) in Korean school buildings. Theindividual supply system has advantages to turn on and off individually and to adjust the thermal comfortseparately, but energy is wasted in the unoccupied classroom when the last leaving occupant does not turn offthe controller. If the controller is to be off automatically while the classroom is not in use, energy consumptionwould decrease dramatically.This project aims to cease the unnecessary EHP supply in vacant classroom by inputting the class schedulefrom the central control room to reduce the energy-spending. Experimental measurements were carried outbetween the controlled classroom that is turned off when not in use and the uncontrolled room that is turnedon continually. Occupant’s comfort and energy consumption were measured and compared between thecontrolled case and the uncontrolled case.The energy consumption of controlled classroom case is 30-60% less than that of the uncontrolled classroomcase. This result shows that controlling the cooling supply for the unoccupied classroom using the classschedule can decrease the energy consumption remarkably. This supply control system can be used to conserveenergy in school structures like universities.
