The Condenser with Fan is a forced-air heat exchanger that removes heat from refrigerant vapor, facilitating its condensation into liquid. Equipped with axial or centrifugal fans, it accelerates airflow across the condenser coils, ensuring efficient heat rejection even in stagnant air conditions. This design is widely adopted in medium to large refrigeration systems (e.g., supermarket chillers, industrial cold rooms) where natural convection alone is insufficient to meet cooling demands.
The variable-speed fans (0.5–3.0 kW) deliver airflow rates of 2,000–15,000 m³/h, adjustable via a PID controller based on condensing temperature. This ensures the condenser operates at optimum heat rejection (30–150 kW) across varying load conditions.
The copper tubes (Φ9.52mm–Φ15.88mm) with corrugated aluminum fins (density 12–24 fins per inch) provide a heat transfer area of 50–300 m², maximizing contact between refrigerant and air. The cross-flow configuration minimizes air bypass, improving heat exchange efficiency by 12%.
The fans are mounted on vibration-damping rubber pads, reducing operational noise to 55–70 dB(A) (measured at 1m distance). Low-noise models (≤60 dB(A)) are available for residential or hospital applications.
The galvanized steel casing (zinc coating ≥80μm) and IP54-rated fan motors protect against rain, dust, and humidity, ensuring reliable operation in outdoor environments (temperature range: -30°C to 50°C).
Integrated fan cycling or speed modulation adjusts airflow to match refrigerant load, reducing energy consumption by 20–30% compared to fixed-speed fans. Some models include heat recovery to preheat water for facility use.
Commercial Refrigeration: Used in supermarket rack systems and walk-in freezers (temperature: -10°C to -25°C).
Industrial Cooling: Applied in process chillers for plastic extrusion and brewery fermentation tanks (cooling capacity: 50–500 kW).
District Cooling: Part of centralized AC plants serving residential complexes and business parks.
Data Centers: Removes heat from chilled water systems to maintain server room temperatures (18–24°C).
Q: How does fan speed modulation work?
A: A temperature sensor monitors refrigerant condensing temperature. If it exceeds the setpoint (e.g., 45°C for R410A), the controller increases fan speed; if below (e.g., 35°C), it reduces speed. This maintains optimal condensing pressure, lowering compressor energy use by 10–15% .
Q: What is the difference between axial and centrifugal fans in condensers?
A: Axial fans (lower pressure, higher airflow) suit large, open spaces, while centrifugal fans (higher pressure, lower airflow) work in ducted systems or enclosed areas. Axial fans are more energy-efficient (10–15% lower power) for most outdoor condenser applications.
Q: How to prevent fan motor overheating?
A: Motors are equipped with thermal overload protection that shuts down operation if temperature exceeds 120°C. Regular cleaning of fan blades (every 3 months) prevents debris buildup, which can block airflow and cause overheating.
