modelling evaporative cooling pads.

[andrewmackay]

I'm attempting to model evaporative cooling pads fitted to chillers for as built Part L compliance analysis.

According to manufacturers data, these can reduce the coil-on air temperature by 10C (although at a fan pressure cost).

Does anyone have any idea or clever work around to include this feature in the compliance assessment?

I don't know what your "Part L compliance" involves, nor am I certain what you mean by "evaporative cooling pads", but there are a few devices in Apache HVAC which allow you to incorporate evaporative cooling phenomena.

Part L compliance as in UK building regulations.

Building regulations require you to perform an analysis of carbon emissions for the building at design stage and at practical completion for an energy performance certificate or EPC.

The VE compliance module is a recognised method of performing this analysis.

And evaporative cooling pads are fitted to the front of air cooled chillers to cool incoming air, reducing the load of the chillers. See Munters manufacturers for more details.

Thanks for the advice, I will look in to HVAC further.

For Part L an simple improvement factor should be applied to the chilling EER value.

I would like to what INNOVATION there is in evaporative cooling – Oh sorry INNOVATIVE Sales BS.

Get yourself a few quotes. Brivis, Bonaire, Breezaire

I have a Bonaire VSL75, WestaFlex QS Ducts & Registers extremely quiet and cools down the house beautifully 350m2 2.7 ceilings 10 points cost me a touch over 4 but installed all myself.

What brand of unit is it anyway? From memory they use CoolBreeze evap cooler WOW – Box, Fan, Pads & a controller some ducting and registers. Yeah real innovative!!!
