Electric Fan Heater Hire
May 6, 2010 by Hanna08
A fan heater is a heater that works by using a fan to pass air over a heating element. This heats up the air, which then leaves the heater, warming up the surrounding area. They can provide very rapid heating of a room, however may be relatively noisy in operation. They are inexpensive to hire and can be used to heat areas where other heating solutions might be difficult to install, expensive or impractical. An example of such an application is their use to heat up small shop kiosks.
Many modern fan heaters for hire have a dial on them that represents “heat”, or the level that you want the heat to get. The fan heater will have a device in it that senses the air temperature or the temperature inside the heater itself. When the temperature of the air being taken into the back of the fan heater reaches this point it will automatically turn off until it senses the temperature is cool enough to turn back on again. This feature helps the fan heaters to not overheat, as the combination of electricity, heat and plastic (which is what fan heaters are normally made from) could lead to a fire if left unchecked.
Fan heaters for hire are usually operated by being plugged into the mains electricity supply. Because fan heaters have (albeit encased in plastic) metal where electric current is passed through, it is important not to get them wet or use them in humid conditions due to the risk of electricution. It is also advised not to use fan heaters when it is warm as they will not have any effect.
A commercial building is required by Title 24 standards to introduce outside air into the occupied space based on the occupancy level of the building and the type of activity being done in the building. For instance a normal office building would have about 15 CFM per person of outside air brought into the building, a lab would see about 25-30 CFM per person. Since additional air is brought in from outside, it will create positive pressure within the building. In order to balance that pressure an equal amount of conditioned air is generally exhausted. That is probably what's happening with the vent that you were lucky enough to discover. Some auditorium's that have digital controls will utilize CO2(carbon dioxide) sensors. An auditorium full of breathing people will create an abundance of carbon dioxide, which requires additonal fresh air. In that case, the level of exhaust air may contain higher levels of carbon dioxide than would be normal, but since you're already standing outdoors the carbon dioxide contained in that exhausted air would probably dissipate pretty quickly. I just wouldn't stick my face into the vent and breathe heavily. Enjoy the cool.

Fair play to Matt Prior. It takes a proper man to have a beard in the hot and humid Aussie conditions, must be uncomfortable! #theashes
This sun is somtin else…still prefer it to being beaten by rain or sweating to death in humid conditions.
