[Equest-users] Process Equipment Power Consumption

[Steven Savich]

Omer,

Absolute agreement - modeling plugload with any degree of certainty is a
headache.  

At least for Office equipment, there is some information, albeit dated:
"Heat Gain From Office Equipment", pp33-39 ASHRAE JOURNAL June 2000 issue.
This article summarizes some information from ASHRAE research projects
RP-822 and RP-1055.

Someone else on the list may know of research that's a little more
up-to-date. 

Steven

Dear All,

One of the things that cause most trouble for us in modelling is the power
consumption of equipment such as dishwashers, ovens, food warm-up
equipment and so on that have varying levels of power consumption during
operation (even PCs and laptops). We are sometimes using nameplate
installed kW values, but deep inside we know that this is quite wrong -
but we have no other more reliable source / guideline for such equipment.
I would appreciate any feedbacks on how others are modelling such
equipment.

Thank you,
