Continuous Diffuser - Manufacturer
Continuous Diffuser - Manufacturer
(OP)
I'm a structural engineer looking for information to help a client on a problem they have outside my area of expertise, so forgive my invasion of the ME forum. The problem is HVAC registers are discharging onto insulated glass units causing the seals to fail prematurely. The attached photos are from 3 or 4 years ago, but show the situation. Since the these pictures were taken the vertical, or lower glass units have been replaced. Some already have condensation between the glass panes or even have interior panes cracked due to the thermal stress. The window manufacturer isn't standing behind the warranty because the original purchaser, the contractor, is no longer in business.
My question is does anyone know of a diffuser manufacturer who may make a deflector so the conditioned air won't blow directly on the glass? Any other suggestions? Thanks, smb

My vote is that the windows are defective. This installation is not exactly new technology.
Is the dodgey window company saying cold air or the hot air is damaging the seals?

The way we build has a far greater impact on our comfort, energy consumption and IAQ, than any HVAC system we install

I've been blowing air on glass for years and never once had a manufacturer complain.
Has the air handling system changed recently: upgraded, replaced components, energy audit? If the air coming from the diffuser changed (to a warm humid airstream?) I could picture the airflow adding to a condensation problem, but typically the exact opposite is true.

The condensation is between the panes of glass, so the condensation is apparently due to the perimeter seal failing.
Thanks for the reply and comments.
