Description

technical field [0001] The invention belongs to the field of wind heating. Background technique [0002] As a clean renewable energy, wind energy is rich in resources, non-polluting, inexhaustible and inexhaustible. It is the most ideal alternative energy and will become the cornerstone of future world energy. At present, the utilization of wind energy is mainly focused on mechanical drives such as wind power generation and wind water pumping. However, with the improvement of the efficiency of wind turbines, another major form of wind energy utilization-wind heating undoubtedly has a good application and development prospect. China has a vast territory and abundant wind energy resources. Especially in the vast rural agricultural production, a large amount of heat energy is required for heating, heat preservation, and drying. Making full use of wind energy to generate heat can produce good economic and social benefits. [0003] The so-called wind heating refers to the conver...
