Coastal area where have free cold and heat source provided by a large amount of seawater, is ideal sites for the application of seawater-source heat pump (SWHP) system to provide cooling and heating. Due to SWHP system providing higher energy efciency and protect environment, it has gradually been applied especially to some governmental key projects in China. In the first phase of Metro Qingdao, eight subway stations are close to the sea. It is convenient to pumping seawater as cooling source, so utilizing SWHP system cooling the subway stations is planed. This paper discussed the feasibility of utilization of SWHP system, from two intake ways. Firstly, bedrock fracture structure on coastal zone was analyzed to study the feasibility of pumping deep fracture seawater for cooling source of SWHP. And the water inflow of pumping test shows that it is infeasible by pumping bedrock fissure water as cooling source. Secondly, the feasibility of pumping surface seawater is discussed. And surface seawater temperature is low enough as SWHP system cooling source. Then SWHP system operation ways are designed preliminarily, and several solutions are proposed to solve troubles which have happened during the use of SWHP system, such as the location of intake and outfall seawater system, seawater causticity and clean technology. The result indicates that Qingdao has great potential for applying surface seawater as heat pump system cooling source in Qingdao metro.

소개
산업화와 도시 집중화 및 교통의 증가에 따른 각종 공해 물질의 증가에 의하여 우리들이 살고 있는 도시환경은 오염되고 있을 뿐만 아니라 도시 생태계가 파괴되어 가고 있다. 이에 따라 우리들의 생산활동이나 공공교통 그리고 일상생활에서 발생하는 대기오염, 수질오염, 토양오염, 폐기물, 소음 및 진동 그리고 그 밖의 오염원으로부터 발생되는 오염물질 등은 인간의 건강 및 생명에 유해하며 나쁜 영향을 미칠 수 있으므로 이를 방지하기 위한 시급한 대처가 요구된다.
이러한 시대적 요청에 따라 본 한국도시환경학회는 도시환경과 관련된 모든 문제를 조사연구함으로써 도시환경학문의 발전과 응용 및 보급에 기여하고 나아가 사회 발전에 이바지함을 목적으로 설립되었다.
