technical field [0001] The invention relates to the field of drying systems, in particular to a combined solar energy-heat pump drying system based on orthogonal optimization. Background technique [0002] The solar-heat pump central hot water system absorbs solar energy to heat the heat transfer oil through the concentrating trough collector, and drives the air source absorption heat pump unit through the high-temperature heat transfer oil to extract heat from the air to achieve the combination of solar energy and air energy. The two new energy sources are naturally integrated. The heating system is provided by solar energy and air source heat pumps in parallel. The defect that a single heat source cannot provide heat continuously. The air source heat pump unit produces heat through the reverse Carnot cycle principle, and its heat production is 2 to 4 times or even higher than the power consumption, which is an efficient and energy-saving heat source; [0003] The existin...

Problems solved by technology

[0003] The existing solar-heat pump drying system does not have the function of heat collection, and directly uses the heat generated by solar energy and the heat pump to act on the drying chamber. Due to the certain temperature difference between the heat generated by the solar energy and the heat generated by the heat pump, it is impossible to realize the drying effect. The stable heating of the drying room will affect the drying process of the drying room, and the drying effect will be affected. Secondly, the precise control of the temperature cannot be realized, and the accurate exchange between solar heating and heat pump heating cannot be satisfied. Therefore, we propose A combined solar-heat pump drying system based on orthogonal optimization
