담수와 해수 열원을 활용한 지열 시스템 히트펌프의 특성에 관한 연구

Though air source heat pump has been required in more and more fields, it is required to improve energy consumption efficiency of heat pump which utilizes waste water/underground water/river water/sea water/contained water heat source in Korea where the four seasons are very distinct. The research states general items about heat pump including its analysis and technology development etc and researches/compares temperature, pressure, enthalpy, amount of heat exchange, COP of heat pump in cooled/heated state to grasp properties of geothermal heat pump system utilizing sea water/contained water heat source. Then it provides the necessity of utilizing eco-friendly sea water/contained water heat source with excellent thermal conduction and diffusion rates as well as a plan to vitalize the source in the future.
