Abstract

Interest in heat pumps is increasing as an eco-friendly and energy-saving heating method. In particular, in order to develop a heat pump capable of heating in a low-temperature area, research to prevent frost on the surface of the outdoor unit is increasing. In other words, when heating through a heat pump in a low-temperature area, a frost layer is formed on the surface of the outdoor unit, which lowers the heat transfer performance, thereby reducing the heating capacity. Therefore, in this study, an adsorption-type dehumidification system is attached to remove the moisture vapor of the air into the outdoor unit of the heat pump. It is believed that this study can suggest the most effective dehumidification method in low temperature regions. In addition, it is expected that a heat pump with high energy efficiency can be developed by attaching an adsorption dehumidifying system to the front of the outdoor unit of the heat pump.

친환경적이고 에너지 절약적인 난방 방법으로 히트펌프에 대한 관심이 높아지고 있다. 특히, 저온 지역에서 난방이 가능한 히트펌프를 개발하기 위해 실외기 표면에 서리가 발생하지 않도록 하는 연구가 많아지고 있다. 즉, 온도가 낮은 지역에서 히트펌프를 통해 난방을 할 경우 실외기 표면에 서리층이 형성되어 전열성능을 떨어뜨려 난방능력을 감소시키는 것이 일반적이다. 따라서 본 연구에서는 히트펌프의 실외기에 유입되는 습공기의 수증기를 흡착식 제습시스템을 부착하여 제거하고자 한다. 본 연구를 통해 저온지역에서 가장 효과적인 제습방법을 제시할 수 있을 것으로 판단된다. 그리고 히트펌프의 실외기 전면에 흡착식 제습시스템을 부착하여 에너지 효율이 높은 히트펌프를 개발할 수 있을 것으로 사료된다.
