The sustainable cooling technology is said to help reduce the carbon footprint of built environments.
The Condair MC is capable of supplying 360 kilograms per hour of humidity and around 245 kilowatts of adiabatic cooling to an air handling unit (AHU) from less than 0.15 kilowatts of electrical energy.
The unit consists of an evaporative module and hydraulic unit, which sits inside the AHU, and a control panel located outside. The evaporative module is a wall of corrugated glass fibre media cassettes, with satinless steel frames, through which the air flows. The hydraulic unit pumps water to the top of the evaporative module to wet the glass fibre media and humidify the air flowing through them.
“With every kilogram of humidity provided by an evaporative humidifier, around 0.68 kilowatts of adiabatic cooling is achieved,” says Ian Eitzen, managing director at Condair Australia. “This sustainable cooling technology presents great potential to reduce the carbon footprint of our built environment.
“We are seeing more and more air handling manufacturers and mechanical and electrical consultants incorporating direct and indirect evaporative cooling strategies into their AHU designs. The new Condair MC incorporates many innovative hygiene, installation and operational features, making it an ideal solution for evaporative cooling or adiabatic humidification,” Eitzen says.
Evaporative humidifiers can provide humidification during the winter to raise an indoor humidity level, as well as offer adiabatic cooling during the summer to economically cool an internal environment. The main advantage over other in-duct spray humidifiers, says a Condair release, is that evaporative units can operate on mains water, without the need for a filtered reverse osmosis water supply. This greatly improves the water efficiency of the system. The benefit over in-duct electrical steam humidifiers is a reduction in energy cost. The energy required to evaporate the water can be taken from the airstream, if excess heat is available, or from cheaper gas-fired pre-heating.
Other features include:
- glass-fibre evaporative media impregnated with antimicrobial additives for hygienic operation
- automated flush and drain cycles to ensure the water in the system is hygienic
- ability to incorporate up to three low-energy pumps with frictionless magnetic impellers that are almost silent
- control panel that provides printed circuit board controlled operation
- building management system connectivity, and
- LED indication of operational status and fault diagnostics.
