EXPERIMENTAL STUDY OF THE PCM WALLBOARD APPLIED IN THE GREENHOUSE
The paper takes the small-sized ordinary greenhouse and the PCM greenhouse we built as the research object. Contrastive experiments were done on the project. Through measuring and comparing the temperature changing of the indoor air, the outer and inner surfaces of the north east and west wall, it discusses the effects of the PCM wallboard on the indoor thermal environment, analyzes the feasible approaches of reducing the heating energy consumption in winter, and preliminarily estimates the effects of the PCM wallboard on aspect of the energy saving for the greenhouse. The experimental results show that applying appropriate PCM to the inner surface of the north wall in the greenhouse can increase the indoor air temperature dramatically as well as reduce power consumption significantly, and make the power saving rate reach 8% as a result.
