ABSTRACT

In order to create a suitable environment and improve the quality of life of the people, the country has paid more attention to the problem of environmental pollution. The drying and drying process of materials accounts for a large part of the total energy consumption. Air source heat pump is an energy-saving device that consumes a small amount of high energy to improve the quality of low energy through thermal cycle, and has been widely used in many fields. The air-source heat pump drying unit can provide efficient drying technology, which is gradually applied in many fields such as production and manufacturing, grain processing, fruit and vegetable drying, etc. In this paper, the working principle of the air-source heat pump drying unit is briefly described, and then its application status in the fields of grain processing, fruit and vegetable planting, stadium reconstruction and so on is described. Finally, the development trend of the air-source heat pump drying unit is proposed from the perspective of technical process optimization.
