Guide
An air conditioner refrigerates and recirculates indoor air; an evaporative cooler passes air over water and needs ventilation. Climate and home layout determine suitability.
A conventional air conditioner transfers heat from indoor air to outside using a refrigeration cycle. A split system moves heat through indoor and outdoor units; a portable air conditioner generally exhausts hot air through a window hose.
An evaporative unit draws outdoor air through wet pads. Water evaporation lowers the air temperature while adding moisture, and the system relies on a path for air to leave the home.
Refrigerated air conditioning can operate with windows closed and removes heat from the room. Evaporative cooling uses fresh outside air and performs best when the air is dry; it needs open windows or other exhaust ventilation.
Humidity affects evaporation. In humid conditions an evaporative cooler may feel less effective and can add unwanted moisture. Check local conditions and the manufacturer's suitability guidance.
A portable air conditioner needs a suitable exhaust route and condensate management as specified by its maker. A ducted evaporative system needs roof equipment, water and ventilation. Include installation, maintenance and electricity in your decision.
For reliable temperature control across varying humidity, consider refrigerated air conditioning. For dry climates, fresh-air movement and a ventilated home, evaporative cooling may suit; compare the available system sizes at /au/air-coolers/conditioning/.
Common questions
Air conditioning moves heat outside through a refrigeration cycle. Evaporative cooling uses water evaporation, adds moisture and requires ventilation.
Air con can cool while the room is closed; an evaporative cooler needs fresh air entering and warm air leaving. The latter is more dependent on dry outdoor conditions.
No. A portable air conditioner uses a refrigeration system and exhaust hose, while an evaporative cooler uses water-wetted media and ventilation.
Refrigerated air conditioning is generally less dependent on outdoor humidity. Evaporative cooling loses effectiveness as humidity rises; check the unit guidance and conditions.
Keep exploring
An evaporative cooler uses water and ventilation; a refrigerated air conditioner uses a compressor and can dehumidify. Climate and the result you need decide between them.
Bonaire Crown 10i is a practical shortlist choice for its published room guidance and portable design. Bonaire Duet suits a smaller spot; Dimplex DCEVP6WT adds a purifier function.
Evaporative air conditioning cools incoming air through water evaporation and needs an exhaust path. Its suitability depends strongly on outdoor humidity and the building layout.
A portable evaporative cooler suits hot, dry air and a ventilated room; a fan-only unit avoids adding moisture. Start with climate, airflow and cleaning needs.
