Circulate cool air around the room and needs doors/windows to be open to create an airflow. Uses water in the tank to cool the air as it is expelled; the water tank can be chilled with ice or frozen ice packs for even cooler results.
Open Room - needs to be open at two points (doors or windows) to create a 'through air flow' for best results. If room is sealed, moisture cannot escape, this will cause high humidity, which creates a higher room temperature.
Vent - no vent required.
Dehumidifier - no dehumidifier.
Humidifier - humidifying function thus avoiding dry air.
Water Tank - water tank - will require topping up.
Humidity - will not operate effectively in humid conditions.
Running Costs - cheaper than Air Conditioners.
Blow refrigerated air for much cooler results. Works on the same principle as a fridge so achieves cooler temperatures than an air cooler. The unit produces chilled air and expels the heat outside via the hose.
Closed room - needs to be sealed for effective operation to avoid warm air entering.
Vent - needs venting by means of a hose through an open window or wall.
Dehumidifier - extracts excess moisture from the air and many dust/pollen particles held in the air.
Humidifier - no humidifier.
Water Tank - water tank or condensation tray may be fitted depending on model. Some models will require emptying periodically.
Humidity - will operate in humid conditions.
Running Costs - higher running costs than air cooler but far greater benefits and cooler results.
