Cry22 .. you mentioned to keep the fan running continously for occupied period of time. but how can it help in bring in the fresh air.. cuz the system is integrated such that all the exhaust from the fan coil units is ducted to ERV units( which is standard ERV with Wheel to extract energy from...
But minimum fresh air requirement cannot be met for occupied period by just circulating the air through the fan, since when fan coil units are off .. ERV is off.
Since building is going for LEED certification.. I dont think its a good idea to leave fan running all the time even if the load is...
Hello everyone!
I have concern about ERV operation schedule.
ERV supply fresh air to the fan coil units in the building.
ERV will keep on running until all the fan coil units are turn off.
Now the problem arises when all the fan coil units are off, ERV will be off and if this situation...
You can put a duct heating coil after the ERV depending upon the temperature you required to raise. You can utilize any free available energy in the building through this heating coil, which I doubt in your case.
