    EPANET alternating nodes with base demand

    Hello. I have drawn the network with all its nodes(with their respective base demands) and its reservoir. Is there a way to run the simulation several times so that each time only specific nodes are "open"(having the base demand already assigned) and for the rest of the nodes base demand is...

    P&ID for DHW with solar collector

    Hi. I have looked into many P&IDs, list of symbols etc. Haven't found what I was thinking of (maybe wrong, trivial, too basic, who knows [shadeshappy] ), besides I'm a little confused about some things. Well here it is the, kind of, P&ID of DHW production(please notice that I omitted many...

    Heat pump ?? in DHW production

    Hello. We say that heat pumps function with a ΔΤ of 5°. Let's say we want to heat fresh water entering our storage tank at 15°C (as it comes from the water main) to 54°C at a flow rate of 0,8m³/h (our secondary circuit). The primary circuit should have a ΔΤ of 5°. Roughly, by energy balance we...

    Solar thermal collectors piping

    Hello. When having several parallel-connected collector strings of different number of collectors each (one string may have two collectors connected in parallel, another eight collectors etc.) does the use of pressure independent balancing valves at the inlet of each string(in order to ensure in...
