Hi everyone,
Just wondering if anyone knows how to improve the efficiency of a heat recovery wheel? Other than good maintainance to ensure its performance, is there any other way to enhance it further? For eg, increase speed of rotation etc. I can't seem to find much info on how a heat wheel is...
Hi everyone,
I've read about Kathabar systems online and am hoping to gather some general feedback, since I don't think it's very much used in Asia yet.
Does anyone have any experience of retrofitting your current systems with it? Is it cost effective? Does it really work in terms of energy...
Hi everyone,
Wonder if you guys can provide a good method of calculating the estimated fan motor power after I reduce the rpm of the fan? The info available are the current fan power, current flow capacity and new flow capacity.
I know there are the fan laws where Q1/Q2 = rpm1/rpm2 and...
Hey all,
Any idea how I can calculate the 3.5 barg nitrogen gas flow rate from a pipe when there's a pipe rupture? Pipe size is 1 in.
I've tried using the choke equation, but the value gotten was quite small.
We did a rough trial (by just fully opening the valve) on site using a 1"...
Hi everyone,
Is there any way that I can calculate the pressure build-up in a room by just knowing the inlet + exhaust flow rates and room volume?
I understand leakages through door gaps should be taken into consideration and they can be calculated using Q = 0.827*A*P^(1/N) [This is in SI...
