【 摘 要 】

China's three northern regions are rich in wind energy resources, with annual wind speeds of more than 3m/s reaching 5,000 hours. Traditional greenhouses use coal-fired heating, which has high pollution and low efficiency. Therefore, the system ingeniously combines wind and heating, and proposes a system that directly combines water agitation heating and greenhouse heating to realize the direct conversion of wind energy to thermal energy. The working principle of the system is: when the wind speed reaches the starting wind speed of the wind turbine, the wind turbine blade rotates to drive the stirring device, and the water in the stirring device is heated by the heat, and when the local table temperature is low, the water can be released, and the water is buried. The serpentine pipes in the greenhouse soil heat the soil, and the temperature in the greenhouse will also increase. At the same time, the temperature in the greenhouse is monitored by the temperature control system. If the temperature rises faster, the fluid flow is adjusted to reduce the heat release. Achieve intelligent regulation of greenhouse temperature to maintain its temperature in a suitable range. The system uses a wind-mixing device to use the abundant wind resources in the Sanbei area for greenhouse heating, thereby keeping the greenhouse temperature stable. From the perspective of green and energy saving, it has created an effective way to warm the greenhouse in winter. In the true sense, the consumption of fossil energy has been reduced, and the criteria for appropriate localization and recycling and renewable development have been realized.
