A Study on the Heat pump - Latent Heat Storage System for the Greenhouse Heating
그린하우스 난방을 위한 열펌프-잠열축열 시스템 연구
Abstract
It is desirable to use the renewable energy for the greenhouse heating in winter season, it make possible not only to save fossil fuel and conserve green environment but also to promote the quality of agricultural products and reduce the agricultural production cost. In this study the heat pump - PCM latent heat storage system has been developed to use the natural energy as much as possible for the thermal environment control of greenhouse. The coefficient of performance (COP) of the heat pump system was 3~4 with the ambient temperature ranging from 8
