Description

technical field [0001] The invention relates to the technical field of heat pumps, in particular to a control method, system, device and storage medium for a heat pump drying unit. Background technique [0002] Drying technology usually refers to the technology of adding heat to wet materials and discharging volatile moisture to obtain solid products with a certain moisture content. This technology is widely used in almost all production industries such as agriculture, food, chemical industry, medicine, minerals, and textiles. Drying is a key technical link to improve product quality in the production process, and it is also a process of high energy consumption. In developed countries, about 12% of industrial energy consumption is used for drying operations. Therefore, the development and application of drying and energy-saving technology is of great significance in today's energy shortage, and heat pump drying technology has significant advantages such as energy saving, hig...

Problems solved by technology

However, these two technologies currently have great limitations and cannot be well applied to various working conditions.

In the former method, the moisture in the oven is evaporated by heating the air, and then the moisture is discharged from the oven through the air duct, so as to achieve the purpose of drying, but if the dried material cannot be baked at high temperature, then This type of unit will not be used normally; in the latter method, only relying on the heat of condensation to raise the temperature makes the heating process very slow and takes a long time, and the humidity in the circulating air is greatly reduced in the later stage of drying. The latent heat of the water will also make it difficult to maintain the heating of the circulating air by the condenser, resulting in a decrease in the temperature inside the unit and greatly reducing the drying effect
