In order to optimize the heat preservation capacity of Chinese solar greenhouse (CSG) and further reduce energy consumption, we clarified the mechanism of the external thermal insulation layer that affects the microclimate environment of CSG.
Rasheed et al. (2019) demonstrated that the management of external thermal insulation can effectively improve the utilization of solar energy in the greenhouse. Although the new thermal insulation material is gradually born in people's vision, but suitable for the promotion of external thermal insulation has been quite mature.
According to statistics of the China Solar Thermal Alliance, by the end of 2021, the total installed capacity of global solar thermal power generation reached 6.8 GW, and the figure in China was 538 MW (only including power generation systems at or higher than the MW scale).
The economic benefit 36.93 USD per day for winter production. The results can provide scientific evidence for the system design of internal insulation in solar greenhouses or other agricultural settings, in order to guarantee the cleaner and energy-saving production of annual vegetable supply in high latitudes and cold regions. 1. Introduction
The rational allocation of external insulation layer based on crop overwintering production in solar greenhouse in high-dimensional and cold areas is put forward, which reduces the waste of resources and strengthens the sustainable development of energy. 5. Conclusion
Research on warming effect of water curtain system in Chinese solar greenhouse Experiment of temperature rising effect by heat release and storage with shallow water in solar greenhouse Modelling and experimental verification of the thermal performance of an active solar heat storage-release system in a Chinese solar greenhouse

Polyiso Insulation Explained
Polyisocyanurate thermal insulation, commonly referred to as polyiso, has proven to be popular due to a combination of its cost effectiveness (i.e. cost per insulation unit), efficiency (i.e. insulation value per unit thickness), and fire resistance, as compared to some competitive materials. Polyiso has recently come to represent over 75% of the commercial roof …

Insulation Materials
Insulation materials run the gamut from bulky fiber materials such as fiberglass, rock and slag wool, cellulose, and natural fibers to rigid foam boards to sleek foils. Bulky materials resist conductive and -- to a lesser degree -- convective heat flow in a building cavity. Rigid foam boards trap air or another gas to resist heat flow. Highly reflective foils in radiant barriers and reflective ...
