Thermal Responsive Performance in a House with Solar Air Collector for Heating
Abstract
Previous researches on solar air heating system (SAHS) major in solar collector, which is separated from building. Actually, even though installed a high-effective SAHS, if ignoring building thermal response characteristics, it cannot obtain good regulation effects of indoor environment. This study takes a test room installed wall-mounted solar air collector on south wall as object, and in the real coldest outdoor environment condition (almost below -5ć during night), it experimentally studies construction thermal response characteristics under different operation condition of solar air heater by utilizing computer multi-circuit detection system and outdoor weather station which can record data automatically, and researches dynamics process of indoor temperature under different factors, such as different air supply modes, movable thermal insulation of window, and direct-gain window’s single action, by analyzing experimental data and numerical simulation. It offers reference for predicting dynamic indoor temperature fluctuation of construction integrated solar air collector system, and further studying on regional adaptation of this technique.
