Abstract

This paper describes the system implementation of the heating operation based on spatial distributing and zonal calorie measuring and analyzing of houses to calculate the fair amount of the heating meterage automatically. The heating space is distributed into 4 zones, which the flow rate and calories are checked by one meter respectively. The system is composed of a heating sources, adjuster of thermostat, valve controller, PC converter and total monitering. The returning temperature in the spatial zones is measured for the heating calorie to calculate the zonal calories according to the rooms temperature. The proposed system results in error by 1% or less in comparing with the dedicated experimental equipment, and reduces energy cost by 7% from conventional system. The fair checking system will be enhanced with building energy management system in the future.

본 논문은 주거공간영역 별로 사용 난방열량을 측정하고 사용량을 자동으로 측정 분석하여 계량 운영 할 수 있는 공평관리 자동난방운영시스템의 구현이다. 난방공간은 4영역으로 분할하여 하나의 계량기로 유량과 열량이 계측된다. 이 시스템은 열량검출, 온도조절기, 밸브제어기, PC컨버터와 모니터링으로 구성된다. 난방 공간영역은 실내온도에 따라 열량 계산에 필요한 환수 온도가 측정되고 영역별 열량이 산출된다. 실험결과, 측정기기로 계측한 값과 비교하여 측정열량 값의 오차 범위는 1% 내이다. 기존의 유량계를 이용한 난방 분할 방식과 비교하면 난방 에너지 사용 비용이 약 7% 저감된다. 이 공평시스템은 향후에는 BEMS와 공동으로 연계하는 연구가 필요하다.
