Schools Educated in Humidity Control

Even though the technology is NOT new, air-to-air heat exchangers I believe are an excellent way to save money on ventilation air, but few schools have embraced this idea.

Kids get sick so quickly in schools and the majority of schools I believe, do NOT have adequate or even state / federal minimum standards for fresh air.

These heat exchangers save big $$ in operating costs and run a long time IF properly maintained.

These things will become a higher priority as fuel costs rise.

Schools have windows which are to take-in and to throw-away energy, at the same

as to have good view.

I propose everybody to consider "SOLAR BLINDS" to save heating energy, and

during the summer time to save energy for cooling classrooms.

SOLAR-BLINDS are available in USA, made in USA, and not know to many people

yet.

If you are serious to save energy through windows, please contact Richard

Sounds to me like you're making a sales pitch for your solar blinds. I don't think this CR4 forum is for marketing.

In humid areas of the country, after hours humidity control is more important than temperature control. Generally speaking, humidity control requires about one building air change per hour, while temperature control uses about six air changes per hour. An energy efficient mechanical dehumidifier uses 75% less power than running an air conditioning system. By installing a humidistat, the dehumidifier cycles off and on as needed for humidity control. The main air conditioner would not even be needed during overnight and weekend hours, unless called for to provide comfort to school staff.

Is this a new dehumidification process or is 75% a little exaggerated? It is a good idea though. After hours internal gains should presumably be mostly sensible as the outdoor air should be minimized thereby saving THAT load. And it is not good to let moisture permeate a building during un-occ period

Its been my experience that most school's HVAC systems are NOT closely monitored or controlled for best operation and cost savings. They run things till they break because of budget constraints.

Newer buildings with automation are much better controlled.

The 75% energy reduction with the mechanical dehumidifier should be fairly accurate. Normal air conditioning requires about six to eight times as much air flow as dehumidifiying with refrigeration.
