Ventilation purges the conditioned space of unwanted pollutants such as organic vapors, dusts, radon and also unwanted product of human activity such as tobacco smoke, carbon dioxide, bacteria and germs.
While ventilation has its benefits, it also increases the cost of air-conditioning. Heat Recovery Wheels greatly help in reducing both operating & initial equipment cost of air conditioning systems. It further helps in energy conservation.
Heat Recovery Wheel is a rotary, counter flow air-to-air heat exchanger designed to provide maximum energy efficiency in ventilation systems where heated and cooled air is exhausted.
InviroTech partners with Klingeburg to bring to you Hugo Heat Recovery Wheels which are high performance and of certified quality.
Working of Heat Recovery Wheel
The wheel is positioned in an AHU so that it is divided into two half-moon sections.
Stale exhaust air is drawn through one half and fresh outdoor air through the other in a counter flow pattern. The wheel is in rotation all this while.
Sensible heat is transferred as the metallic substrate picks up and stores heat from the warmer air stream and gives it up to the cooler one.
Latent heat is transferred as the desiccant coating on the metallic substrate adsorbs moisture from the air stream that has the higher humidity ratio and releases the moisture into the air stream that has the lower humidity ratio.
It is positioned within the supply and exhaust air streams of an AHU in order to recover the heat energy.
These are some of the very effective tips given for a better HVAC system. And the maintenance guide is distinguish and useful. Heating and Cooling Vaughan
