Abstract
Passive solar greenhouses are developing rapidly in China and they can significantly increase crop yields. The main reason for this increase in crop yield is the availability of a suitable thermal environment. In order to investigate the thermal environment of the heliostats in the high latitude water-scarce and cold region of Shanxi, the thermal environment of the heliostats in this region was measured in this paper, and the results showed that the highest temperature of the heliostats was located in the eastern part of the crop area at about 4m from the back wall; the highest and lowest temperatures of the heliostats were located in the eastern part of the crop area;the maximum and minimum temperatures in the greenhouse were located in the eastern part of the crop area, and the temperatures in most of the crop area exceeded 30°C. This research can provide theoretical support for the construction and management of solar greenhouses in low heat and water areas at high latitudes.
