In a local swimming pool fresh air is drawn into the building, heated and blown into the pool room. The hot moist air then drifts across the pool via some poorly placed air-supply grilles and is then exhausted through roof extract fans! What is the best way to improve the heating system?
On the attached jpg are two pictures. First picture "part of fan coil" is due for installation on a roof to be part of the fan coil unit. What is it & what are the kinds/levels of leakage do they have/if any?
Finally, does anyone recognise the second picture?
How can one tell if the "power factor" of a building has been altered/corrected to a better value. Is there any tell tell signs without the owner or anyone else being present to ask. Finally, wat is likely to be the power factor of an electric heater with simple resistance?
