Energy Efficient Removal of Excess Heat

Evaporative Cooling and Humidity Control can be achieved through the adiabatic process to improve productivity and workers' wellbeing, as well as helping to remove excess heat generated in many industrial and manufacturing processes

In industrial facilities, many processes generate excess heat. Not only does this drive the temperature up, it also causes relative air humidity to drop with all the negative side-effects this can have: Risk of electrostatic discharge, desiccation of products, reduced comfort for the employees and less control of production processes.

By evaporating water using an air humidifying system, these side-effects can be reduced or eliminated – and the evaporative effect of introducing water spray into a hot room will provide an energy-efficient cooling effect, as well.

How to turn 2 W of electrical energy into 630 W of cooling effect

An air humidifying system using cold water can create a significant cooling effect using very little energy. It is the evaporation of the water that causes the whole system to dissipate energy through an adiabatic process described below – the science behind all this is highly complex, but the effect is both measurable and predictable.

The cooling effect of evaporating water vapor is approx. 630 W of cooling effect per kilogram of water evaporated – and for each kilogram of water, an energy input of approx. 2 W is required in an Airtec® high-pressure air humidifying system. In other words, by exploiting a naturally occurring process, evaporative cooling is a highly energy-efficient method for cooling rooms and production facilities with local heat sources.

This energy efficiency comes from the fact that, unlike conventional air conditioning systems, evaporative cooling happens naturally without the need for compressors and other power-consuming components.
