Diagraming Heating and Cooling Load Calculations Over Time
jameshowison
| Posted in General Questions on
Is there a way to get a time series of heating/cooling loads (for a location and a design). I’m familiar with Manual J which gives max design loads but I’d really like to see loads over time. Ultimately I’d like to play around with some visualizations for communicating about equipment sizing and turn-down ratios.
Could one take Manual J design loads (especially room by room loads) and map them onto curves derived from heating/cooling degree days for a location (averaged over some period?).
Or is this something available in simulations like BEOpt or others? Happy to be directed to other forums etc.
Thanks,
James

You can download daily degree day data for a location at degreedays.net, if that's good enough for what you want to do.
I built a simplified manual j spreadsheet ms-excel that supported different design temperatures for November through April. That I used to help size a heat pump and boiler turn down ratios. Have you tried just using a spreadsheet?
