Solar Heat Pump Degydrator Core Technology
- Hybrid Energy System
Integrates photovoltaic panels and air-source heat pump technologies. Utilizes direct-expansion design to enable solar energy to directly drive refrigerant evaporation. Coupled with R134a/R1233zd(E) mixed refrigerant for stable operation across a wide temperature range (-30℃ to 180℃). Achieves COP values of 5.56-8.83, reducing energy consumption by >85% compared to traditional drying equipment. - Intelligent Control Module
Features a touch-screen control system supporting four auto-switching modes (Solar-only/Hybrid/Heat Pump-dominant/Emergency Electric Auxiliary). Temperature control precision: ±0.5℃. Pre-programmed drying profiles for 24 materials including herbs and agricultural products.

Working Principle Visualization
- Solar Energy Harvesting Phase
PV panels convert light into electricity to drive the compressor. Simultaneously, collectors heat thermal oil to 65°C, ensuring dual-energy reliability. - Heat Pump Cycle Phase
Operates on reverse Carnot principle:- Evaporator: Absorbs ambient heat (operates at -20℃)
- Compressor: Elevates temperature to 100℃ high-pressure gas
- Condenser: Releases heat to drying chamber (temperature gradient ≤2℃)
- Waste Heat Recovery System
HRS (Heat Recovery System) recaptures 60% heat from humid exhaust air, reducing energy consumption by 36.36%.
Typical Application Scenarios
- Chinese Herbal Processing: 50℃ low-temperature drying preserves active ingredients (e.g., astragaloside)
- Seafood Dehydration: Gradient heating prevents protein denaturation
- Industrial Sludge Treatment: 90℃ high-temperature mode enables eco-friendly disposal
