Title:
OPTIMAL DESIGN METHOD FOR LARGE-SPAN VARIABLE-SPACE SOLAR GREENHOUSE FOR HIGH-EFFICIENCY PRODUCTION THROUGHOUT THE YEAR
Document Type and Number:
WIPO Patent Application WO/2022/193846
Kind Code:
A1
Abstract:
An optimal design method for a large-span variable-space solar greenhouse suitable for high-efficiency production with near-zero energy consumption throughout the year. The method organically integrates the solar photovoltaic technology, electrothermal film technology, phase change heat storage technology, and building wall construction technology with the architectural space design of the solar greenhouse and its thermal environment creation method, such that in winter, the phase change heat storage wall can achieve the transfer of solar energy location and time in the form of "solar light-electricity-heat" plus "solar light-heat" to provide a heat source for the solar greenhouse at night; and in other non-heating seasons, ventilation and cooling of the solar greenhouse can be achieved, and power for agricultural machinery can be provided. After the geographic latitude of a construction site and the critical period of vegetable production that the greenhouse needs to ensure are determined, the local average outdoor air temperature and total daily average solar radiation in the corresponding period are looked up to calculate the optimal design values of architectural spatial morphological parameters of the solar greenhouse, such as the height-span ratio of the solar greenhouse, the projected length of the rear roof, and the height of the north wall, under corresponding span conditions. In this way, the high-efficiency production of the solar greenhouse throughout the year can be achieved, and solar photovoltaic modules can be efficiently utilized throughout the year, and the consumption of ventilation devices and agricultural machinery can be lowered.
