Cinemas / Theatres HVAC 1

Does anyone know the figure for heat load from projectors.
Also, should I consider heat load from screens, and if so how much?

Thanks a lot.

The unit of measure of heat generation is BTU (British Thermal Units). Often, the projectors BTU value will be included on the spec sheet. If not, use this simple formula to determine the BTU output of a projector: Wattage X 3.42 = BTU
If you are dedicating an air conditioning unit to the projector enclosure, you should rate your conditioner at 120% of the projector BTU rating. As an example, an air conditioner that exchanges 5000 BTU would satisfy a projector that is rated at 4000 BTU.
Note: Do not rely on an HVAC system that is intended to support a particular area of a venue to provide cooling for the projector enclosure. The problem with this approach is that the thermostat for that HVAC system is located in the room, not in the enclosure that houses the projector. Therefore, the projector environment will not receive adequate cooling. Another risk with this approach occurs in the winter, when the thermostat is set to output heat. In that instance, the projector enclosure would be receiving heat, as opposed to cooling.
