Appliance Heat Gain

[CarolinaPE]

I am currently working on an office building which contains a kitchen. The only info I could find for heat gains given by the appliances were 1,000 W for a microwave and not much for the range/oven. Each kitchen will contain a microwave and consumer type oven. Does anyone have good info or rule of thumb to use for the appliance heat gain in the kitchen? I also have found heat gains for a standard business copy machine listed as 1000-1500 W as well which seems high. I was planning on using about 200 W per desktop computer with monitor. Thank you for your input.

Is the kitchen equipment going in an office kitchen or were you gathering information form your own office kitchen? When I figure cooling loads for office kitchens, I don't count ovens or microwaves because they are so infrequently used. I do figure a 100W load for a standard refrigerator and 1500W for a coffee maker as these items are used almost all day.

If the oven is in a residence, I use AHSRAE value of 1600 Btuh.

The computer load of 200W per workstation seems high. I figure 150W and even that's on the high end. I figure it covers other minor items like clocks, printers, etc.

Yes, the equipment is going in an office kitchen. What you have done sounds pretty reasonable, is 1,500 W about right for a typical coffee maker? Just wanting to make sure that is not a typo. I did find similar info in ASHRAE books but it looks very outdated. Thanks.
