Evaporative cooling works best when relative humidity stays below 60%. In arid and semi-arid regions where summer temperatures exceed 35°C and humidity often drops below 40%, evaporative air coolers can lower indoor temperatures by 5°C to 15°C while using only 10% to 25% of the electricity consumed by traditional compressor-based air conditioning....
Cellulose cooler pads win on raw cooling performance, while synthetic pads win on chemical resistance and service life in harsh water conditions. For most greenhouse cooling, farm ventilation, factory ventilation, and workshop cooling setups, cellulose honeycomb paper is the better choice: it reaches a saturation efficiency of 80 to 92 percent an...
If your space is large, dusty, or hot but not humid — such as a workshop, greenhouse, or factory floor — an evaporative air cooler is generally the better and far cheaper option. If you need precise temperature and humidity control in a sealed, humid environment, a traditional air conditioner is the right choice. In most industrial, agricultural,...
The direct answer: cellulose honeycomb paper (wet curtain paper) outperforms all competing materials in real-world evaporative cooling applications. A 100 mm thick cellulose honeycomb pad delivers saturation efficiency of 80–92%, can drop outlet air temperature by 5–15°C, and lasts 3–5 years with proper maintenance. For factory ventilation, wor...
