가스난방기인 GHP의 인기가 급부상하면서 1995년 선을 보인 후 GHP시장이 올 한해 보급대수만 3천5백대에 달할 것이라는 소식이며 이는 지난해보다도 3배이상 늘어난 수치이다. GHP가 각광을 받는 것은 청정연료인 가스를 사용하고 우수한 냉$\cdot$난방효과를 얻을 수 있는 데다 기기 수명이 길고 유지보수가 간단하게 이루어지는 등 장점이 많다는 점에서다. 또한 친환경적이라는 측면에서 매우 긍정적이며 여름철 전력난 해소에도 기여한다는 점에서 국가경제에도 매우 크다고 할 수 있다.

Recently, environmental concerns and issues have become great concerns for the public. Therefore, this study is conducted with the objective of preventing energy depletion and $CO_2$ emission. PCM (Phase Change Materials) having latent heat characteristic is mixed in mortar to find a proper mix proportion. Also, the mortar properties and performances as well as a melting point of PCM when applied to air conditioning and heating conditions in at building environments were obtained by performing experiments. Also, latent heat and heat transfer characteristics were obtained from experiments by test of thermal performance to formulate temperature gradient about amount of heat transfer of PCM content using the Fourier's thermal equation. The study results can be used in the application of PCM in buildings and expected effect of air conditioning and heating energy.
