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.

공동주택에서 난방용 에너지를 절감하기 위한 난방제어기와 난방계량기의 효과적 활용방법을 중심으로 난방열량 제어 관리방안에 대하여 기술한다. 우리나라 공동주택 난방방식에 주로 이용되고 있는 바닥패널 이용 복사난방시스템은 공간의 단열특성, 난방패널의 열적 및 수력학적 특성, 열원공급 및 제어방법에 따라 주거용 건물의 에너지소비에 큰 영향을 미치고 있으나 적절한 설계 및 운영방법이 제대로 마련되어 있지 않아 국가적인 차원에서 많은 양의 난방용 에너지가 낭비되고 있는 실정이다. 특히 공동주택에 설치되는 바닥패널 난방시스템과 관련된 문제점들로는 실내온도 및 난방열량의 제어방법과 난방용 열량의 계량방법 등을 들 수 있다. 그림 1은 공동주택에 설치된 난방제어기와 난방계량기의 모습을 보여주고 있다.

The measuring apparatus such as heat meter is legally obliged to be installed and used for heat rating with heat or flow rate in residential buildings in Korea. There are two kinds of apparatus to measure heat consumed at each households, i.e., heat meter and hot water flowmeter. Contrast to the most of buildings with hot water flowmeter well being used for rating, heat meters have been used only 42.6% in the buildings with central heating system. But there is a critical problem in the course of using hot water flowmeter for heat rating, yielding distorted and unfair result which is different from the real value of heat supplied. Experiments with several parameters were carried out in this study to analyze this phenomenon quantively and alternative methods were proposed for rational heat rating.
