As drone operations expand in logistics, surveillance, and agriculture, maintaining optimal battery and electronics temperature in drone hangars is critical. Two dominant cooling technologies—semiconductor (TEC) cooling and compressor-based refrigeration—offer distinct advantages. This study evaluates Huajing’s HJ-5000 series(compressor) and HJ-TEC30(thermoelectric) chillers for drone hangar applications, focusing on energy efficiency, reliability, and operational costs.

Technology Comparison

1. Semiconductor (TEC) Cooling

Uses the Peltier effect to transfer heat via electric current, with no moving parts.
Huajing product: HJ-TEC30(30W cooling capacity, compact design).

Pros:

· Silent operation (ideal for noise-sensitive environments).

· Lightweight and vibration-free, protecting sensitive drone sensors.

· No refrigerants (eco-friendly).

Cons:

· Lower cooling capacity (~30–100W range).

· Higher energy consumption per watt cooled.

2. Compressor-Based Cooling

 Uses refrigerant cycles (e.g., R134a) for high-capacity heat removal.
Huajing product: HJ-5000(5kW capacity, scalable for large hangars).

Pros:

· High efficiency (COP of 2.5–4.0).

· Scalable for large spaces (5kW–20kW models).

· Lower long-term energy costs.

Cons:

· Requires refrigerant maintenance.

· Slight noise/vibration (mitigated by Huajing’s low-noise enclosures).

Key Metrics Comparison

Recommendations for Drone Hangars

1.  Small-Scale Operations: Choose HJ-TEC30 for cooling individual drone batteries or electronics enclosures. Its compact size suits mobile or temporary hangars.

   
   

2. Large Hangars/Fleet Bases: The HJ-5000 compressor chiller delivers higher efficiency for climate-controlled spaces with multiple drones.

   
   

Industry Trend Note:

With rising demand for energy-efficient drone infrastructure, Huajing’s hybrid solutions(e.g., TEC for spot cooling + compressors for ambient control) are gaining traction in smart hangar designs.

Conclusion

While semiconductor cooling excels in niche applications, compressor systems dominate large-scale drone hangars due to superior energy efficiency. Huajing’s HJ-5000 and HJ-TEC30 provide tailored solutions aligned with industry needs for reliability, scalability, and sustainability.
