  • In terms of district heating operation, efficient production and supply of heat by alleviating the peak load at a specific time require an application technology that can solve the inconvenience of the user and the difficulties of the supplier. In this study, a 78 ℃ class PCM heat storage tank suitable among the technologies that can solve these problems was manufactured and applied to the hot water supply facility for apartments in district heating users. As a result of the application of this system, it was confirmed that the supply temperature was constant to the user compared to the existing supply method. In addition, it was confirmed that the reduction of the peak load due to load equalization reduced the heat supply margin of 10% in the existing heat supply facility. And the construction cost of the new heat supply facility and the construction cost of heat users is decreased by 5% and 10%, respectively.

  • 태양열시스템은 하절기에 급탕과 난방 부하가 적거나, 거의 없어 시스템의 과열 문제가 야기 될 수 있다. 이를 해결하는 방안 중에 하나로 흡수식 냉방시스템을 이용하여 하절기 잉여열원을 활용하여 냉방하는 방법이 대두되고 있다. 태양열 냉방시스템은 전기에너지를 대체하는 효과 뿐 아니라 태양열 연간 이용 효율 극대화에도 크게 기여 할 수 있다. 본 고에서는 국내 기술로 최초로 개발 실용화된 중온용 단일 진공관형 태양열 집열기와 1중 효용 흡수식 냉방기를 이용하여 실증연구를 계획하였다. 태양열 냉방 실증을 위하여 단일 진공관형 태양열 집열기 집열면적 200m2, 축열조(태양열, 급탕, 냉수), 10RT급 냉방기, 냉각탑, 보조 보일러, 원격 제어 및 모니터링 등이 계획 되었다. 실증시험 중간 결과 태양열 냉방시스템은 하절기 맑은 날 하루 동안 약 5 - 6시간 안정적으로 가동 되었으며, 앞으로 온수급탕, 난방 시험을 거쳐 시스템 성능 및 경제성 평가를 통하여 유용성, 안정성 및 신뢰성이 검증 될 계획이다.

  • In this paper, an experiment was carried out to investigate the thermal behavior and performance on a solar space heating & hot water system in an apartment. Measurement was continued for 6 months between January 1st 2004 and June 31th 2004. The results show that there is no problem in control and operation in case of connection this system with conventional space heating and hot water system, and that the thermal performance of this system and indoor thermal environment is good.

  • The purpose of this study was to suggest specific evaluation data for heating and DHW energy consumption characteristics through analyzing energy consumption measurement data of gas boiler in Apartment Buildings with individual heating systems. To do this, it was measured both gas flow and electricity for heating and DHW respectively, and then it was analyzed not only characteristics according to energy sources; gas and electricity, but also the effect of various factors on heating and DHW energy consumption. The result of this study were as follows. It was developed the electric energy estimation model of a gas boiler through analysis on patterns by energy sources. And the effective factors for heating and DHW energy consumption were demonstrated as follows: the area for exclusive use, the number of auxiliary heating equipments, the number of occupants, and the number of sanitary fixtures.

  • This paper studied the economical efficiency of ground source heat pump system under various conditions in apartments which have important effects on the housing market. And this study analysed the initial cost increase, saved managing cost and recovery time of initial cost. Analysis result showed as time of heating-cooling and water heating increases, the amount of saved managing cost increased much than the initial construction cost, so recovery time shortened. And as the net area of apartment increases, the recovery time increased. The study of the relation between the installation type and recovery time of initial construction cost showed when heat-cooling system adapted ground source heat and water heating system adapted waste heat, the initial construction cost was recovered most quickly. When Ground Source Heating system was used for the heating-cooling and water heating system, ground source heating system was used for the heating-cooling and waste heat used for water heating, and ground source heating system was used for the heating-cooling and LNG used for water heating, the construction cost increased 72,000, 66,900 and 62,300 won each per $m^2$ compared to the current system (package air-conditioner, heating and water heating using LNG).
