Abstract

The invention relates to the technical field of a facility agricultural engineering, and particularly relates to a solar greenhouse for collecting heat by an air sac membrane. The solar greenhouse comprises a bracket, a heat collecting device arranged at outside of the bracket and a fan used for providing power for the heat collecting device; the heat collecting device comprises the air sac membrane covered at the outside of the bracket and a heat collecting heat-insulation grain circularly moved along the inner part of the air sac membrane under the driving of a fan. Through the air sac membrane covered at the outside of the bracket and the heat collecting heat-insulation grain circularly moved at the inner part of the air sac membrane, the air sac membrane and the heat collecting heat-insulation grain are used as the heat collector; thus the heat collecting heat-insulation grain in movement can continuously absorb energy from incident light in the air flow path of the air membrane path, the heat collecting efficiency of the greenhouse is greatly improved.

Description

technical field [0001] The invention relates to the technical field of facility agricultural engineering, in particular to a solar greenhouse using an airbag film to collect heat. Background technique [0002] In the vast majority of Northwest China and North China, it is easy to cause serious damage to greenhouse vegetable production when the winter cold snaps. Fortunately, in most areas north of the zero-degree isotherm in January in my country, solar energy resources are very rich. Therefore, using solar energy to store energy and adjust the temperature of greenhouses is in line with the current development trend of low-carbon energy conservation and has broad development prospects. . [0003] At present, in addition to relying on solar radiation during the day, solar greenhouses must be artificially heated at night, such as flue heating, hot stove heating, etc. These traditional heating methods have low heating efficiency, consume a lot of traditional energy, and increas...
