건물 특성에 따른 냉수 순환 펌핑 시스템 별 에너지 소모량 분석

초록

This study analyzed the energy consumption of a building pump system that was originally equipped with a primary- secondary zone pump system. Using the HYSYS program the energy consumption of the primary pump system was compared with the primary-secondary zone pump system. The primary-secondary zone pump system consumes less energy than the originally designed primary pump system. When the distance between the machine room and each building is assumed to be equal, the primary pump system can be more efficient than the primary-secondary zone pump system with decreasing the distance. When the distance is 120 m, the primary system consumes less total annual energy than the primary-secondary zone pump system and saves 2,773 kWh. The suggested energy evaluation program can be useful if the designer seeks a more efficient pump system.
