We have an Air Handling unit which we have recently converted from steam to Natural Gas by replacing the steam coils with the Indirect Fired heat exchanger. The unit is 60,000 cfm. We want to install smoke detectors in it, 2 before the heat exchanger and 1 before the fan. I just wanted to know...
There is not heat load in that area since its abandoned. Only pipes running through that and some conveyors over there. I am thinking of using 0.5-0.75 cfm/sq ft only for that abandoned area and use the rest of the cfm to deliver somewhere else. That other place is occupied and it has people in...
Hello Guys,
I just need a little help. We have two big Air houses each has a capacity of 240,000 cfm, and these are serving the areas which are abandoned, they only have machinery and steam and other condensate pipes. We also have a few small air houses which are near to these two big giant...
Hey guys,
I want to calculate the steam load of the coil. I know the fan CFM and outdoor and indoor air temperatures. Should I use the formula Q=4.5*cfm*delta(h).?
If yes I was wondering how would I calculate the enthalpy because I dont know the wet bulb temperature. I am confused maybe I am...
Yeah I know I need to know the fan curve and the system curve but the system I am handling with is too old built in 1950s and we don't have any OEM data for that. So I was just trying.
Hello,
I want to calculate the static pressure of a zone. I know the cfm the fan is delivering, I know the motor HP. I was just wondering if there is any way to calculate the static pressure in the system based on these values or do you have to use a pitot tube or a manometer to determine that...
