In severe cases, frost can block airflow. This causes system overwork.

Relative Humidity	Heat Transfer Rate Impact	Overall Heat Transfer Coefficient Impact	Pressure Drop Impact
60%	Minimal	Minimal	Minimal
70%	Moderate	Moderate	Moderate
80%	Significant	Significant	Significant

Operating in extremely low temperatures increases frost risk. The heat exchanger's surface temperature drops below the dew point. This causes rapid moisture freezing. Poor system insulation allows cold air to penetrate. This leads to uneven cooling and frost formation. Insufficient airflow also contributes. Blocked or dirty air filters, obstructed vents, or malfunctioning fans prevent efficient heat exchange. This can lead to frost buildup. Low refrigerant levels, often due to leaks, also reduce heat transfer. The material of the tube fins significantly affects performance. Copper offers the best heat exchange. Aluminum is less expensive but lacks corrosion resistance. This leads to dirt thermal resistance. Stainless steel has the worst performance. Research indicates copper fins result in a higher air-side heat transfer coefficient. This is true compared to stainless steel or aluminum fins. The processing technology of tube fins also influences heat transfer. Mechanically connected fins are prone to contact thermal resistance. This negatively impacts heat exchange.
