Intelligent Heat Pump Drying Kiln

Dual-function Air Energy Heating and Dehumidification

1. The closed-loop air heating system for drying rooms eliminates the need for dehumidification vents on the top, significantly reducing heat loss from moisture removal. By fully utilizing the heating and cooling functions of the air energy system, it achieves 1.3 times the efficiency, resulting in remarkable energy savings.
The seamless integration of open-loop heating and closed-loop dehumidification is a refined technology developed over years of experience. We have perfectly combined these functions through computerized operations, making the process simple to operate with automated data analysis and calculations. Drying one cubic meter of hardwood consumes approximately 85 kWh of electricity, creating unprecedented cost-effectiveness in the drying industry.

2. Long Service Life of Closed-Loop Heat Pumps: With proper maintenance, closed-loop heat pumps can operate for 20 years or longer. The system boasts an extended operational lifespan, low maintenance costs, and convenient upkeep.

3. Strong Stability: Closed-loop heat pumps utilize a substantial ground-source heat storage capacity and maintain stable temperature distribution, ensuring reliable and stable operation.

4. High Reliability: The modular design of closed-loop heat pumps allows for flexible adjustment of the number of units based on usage requirements, enhancing system reliability.

5. High Efficiency and Energy Savings: Closed-loop heat pump technology enables the recycling of heat and humidity, significantly improving energy utilization efficiency and reducing energy consumption, thereby achieving notable energy savings. It is 20% more energy-efficient compared to open-loop heat pumps.

The installed dehumidification system inside the kiln can operate normally at temperatures up to 63°C.

Actual view of the entrance: 8.6 meters in length × 7 meters in depth × 4.3 meters internal stacking height.

Inside the kiln, the 3KW fan and heat exchanger, when the air energy system is operating, absorb heat from the outdoor air and transfer it to the heat exchanger to raise the temperature inside the kiln, achieving energy-efficient and rapid heating.

6. Strong Controllability: Equipped with adjustable temperature and humidity control functions, it can be fine-tuned according to the requirements of different materials, ensuring optimal drying effectiveness and quality.

7. All-weather Heating: The closed-loop high-temperature heat pump system operates stably, unaffected by seasons or climate changes, enabling all-weather heating and hot water supply.

8. Energy-Saving Technology Highlights:

The air-energy heat exchanger and refrigeration unit inside the kiln are both made of fully aluminum materials for corrosion resistance. Moisture in the kiln is discharged in the form of condensate water rather than being vented as hot steam from the top, significantly reducing electricity consumption. The energy saved translates directly into pure profit.

9. Scientific Control Logic:

By rationally utilizing the balanced characteristics of heat pump heating and cooling, the system ensures temperature maintenance through heating while achieving dehumidification through cooling, thus achieving optimal energy balance.
