I'm in the process of building the basement for my own new home. As an engineer myself, I understand each engineer develops their own prescriptive or 'template' designs for certain common details. In that context, there's a detail in my structural engineer's wall rebar design for which I'd like...
I created a spreadsheet to calculate hydronic loop pressure drops. To make the spreadsheet more functional, I regressed several AquaPex friction tables for the velocity range of interest. AquaPex tables are unusual in that they account for water temperature, providing a higher degree of accuracy...
Attached is a diagram showing how thermal energy storage (TES) can be installed in parallel between chiller and load. The 2nd page is an excerpt from an ASHRAE Journal article by Kent Peterson on which this design is based. When only the chiller is operating, the zone valve on the fan coil is...
Without going into the "whys"... I'm designing a chilled water A/C system that must operate over an unusually wide range of entering water temperature (40F-63F) and flow rates. The flows will be laminar the majority of time, with Reynolds numbers in the three fan coil circuits as low as 1000...
