As water is evaporated, energy is lost from the air, reducing the temperature. Two temperatures are important when exploring the art of evaporative cooling systems.

Dry Bulb Temperature

  • This is the temperature that we usually think of as air temperature, measured by a regular thermometer exposed to the air stream.

Wet Bulb Temperature

  • This is the lowest temperature that can be reached by the evaporation of water only.

When considering water evaporating into air, the wet-bulb temperature, as compared to the air’s dry-bulb temperature, is a measure of the potential for the art of evaporative cooling. The dry and wet bulb temperature can be used to calculate the relative humidity.

Evaporation will take place when the humidity is below 100% and the air begins to absorb water. Any given volume of air can hold a certain amount of water vapour and the degree of absorption will depend on the amount it is already holding.

The term humidity describes how much water is already in the air; relative to the amount it is capable of holding. Air is saturated when it cannot hold any more water. Imagine it as a sponge, if the sponge held half as much water as it was capable of holding, it would be 50% saturated. In the case of air, we would describe the Relative Humidity as being 50%.

Energy is required to change water from liquid to vapour. This energy is obtained in an adiabatic process from the air itself. Air entering an evaporative air cooler gives up heat energy to evaporate water. During this process, the dry bulb temperature of the air passing through the cooler is lowered.

How Does an Evaporative Air Conditioner Work?

art of Evaporative Cooling

 

Evaporative air conditioning uses evaporation to cool the air. In an evaporative cooler, such as Breezair, a pump circulates water from the reservoir on to a cooling pad, which in turn becomes very wet. A fan draws air from outside the unit through the moistened pad. As it passes through the pad the air is cooled by evaporation. The key to effective evaporative cooling is ensuring that each of the cooling pads are completely saturated at all times during operation and that the systems fan & motor are sized and designed to deliver the appropriate airflow for the home.

All Breezair units feature advanced technology and a range of clever design features that combine to achieve the highest cooling performance of any comparable air conditioner.

Why is Breezair Unique?

Breezair units feature advanced technology and a range of unique and clever design features that combine to achieve the highest cooling performance of any similar air conditioner.

Your home deserves the finest ducted evaporative air conditioning available in Adelaide. So it makes good sense to choose the revolutionary Breezair Icon – the world’s quietest and most efficient ducted evaporative air conditioning system.

A Breezair Icon series evaporative air conditioner uses up to 90% less electricity than refrigerated units (including split systems and reverse cycle air conditioning) and up to 40% less electricity than conventional ducted evaporative air conditioning systems (without an inverter).

Revolutionary Hushpower Direct Drive

Exclusive to Breezair, this motor is super efficient and electronically controlled for optimum efficiency. Corrosion resistant, it’s the quietest motor available and has unsurpassed reliability, reduced energy use and runs at variable speeds.

Centrifugal Fan

Centrifugal fans are the first choice of air conditioning engineers worldwide. The Breezair forward curved, centrifugal fans are made from injection-molded polypropylene. They are double-width, inherently statically and dynamically balanced, with aerofoil blades to provide high pressure performance and very low noise levels.

Axial Fan

The better the fan, the more efficient the system. This super powerful fan is designed to maximize performance and minimize noise. The purpose designed fans are inherently balanced, with aerofoil blades to provide energy efficient, high pressure performance.

Permatuf Corrosion-Proof Cabinet

The Breezair cabinet will not corrode or rust. The UV stabilized structural polymer material is the same type used to make acid baths, battery cases and some space satellite components. Plus, it’s designed to blend with any property.

WaterManager System

The Breezair WATERManager ensures optimum machine life with minimum maintenance by constantly checking water quality. As the water in the air conditioner evaporates, it leaves behind impurities and sales, which then become deposited on the cooling pads and cause the cooling power to fall, The WATERManager System senses water quality with a probe that deeds a signal back to the electronic module, which then ejects some dirty water and allows fresh water to enter.

 AQUAflow Non-Clogging Water

Breezair’s AQUAflow non-clogging water distribution is one of the things that make it unique. The water distributor maximizes cooling efficiency by supplying a continuous and balanced flow of water across the cooling pads. This is different to any other brand of evaporative coolers, which are subject to water flow variations for a number of reasons. Breezair’s balanced flow ensures highest evaporation efficiency and maximum cooling.

Chillcell High Efficiency Pads

With strong, long-lasting Chillcel pads that last for up to seven years, maintenance is easy. Chillcel pads are made from organic paper materials, cleverly manufactured into honeycomb panels that have excellent structural and cooling strength. They are easy to clean and replace when necessary. Seeley International has been using Chillcel pads in our products for decades, so they have a proven track record.

AutoWeatherseal.

The AUTOWeatherseal closes the duct automatically – stopping convection currents in winter from allowing cold air to enter, or heat to escape. When the fan is off, the Breezair AUTOWeatherseal shuts and blocks those air currents. The result – a more comfortable environment in winter and no need to add covers during the off season.

Tornado Pump

The perfect pump for the job! The Tornado pump is built to last. Designed, manufactured and tested by Seeley International, the Tornado pump epitomizes reliability. It features very safe material choices, an encapsulated motor with overload cut-out, stainless steel shafts and bearings fully protected from water. Plus, it has a clever impactstart feature that will overcome any tendency for the pump to become locked up with residue during prolonged off periods. The strong synchronous motor has constant speed, independent of voltage fluctuations, and runs very cool.

Seelectric Motor

Breezair’s fan motor is fully enclosed to international standards and excludes any moisture ingress from all sources. The advanced design is rigorously tested and completely reliable single phase induction motor, exclusive to Breezair, designed and built to the highest mechanical and electrical standards..

Digital Smart Box/Control Power Module 

A state-of-the-art digital electronic control means optimum performance. The Smartbox digital control module monitors and controls all of the air conditioner’s features to provide ultimate comfort conditions, temperature sensing and water quality supervision – completely safely and reliably. The module also incorporates diagnostic features and memory to aid troubleshooting and minimize downtime. Several user choice parameters are available to allow you to set up your preferred environment.
