A typical whole-house fan, with louvers closed when not operating. A whole house fan is a type of fan, commonly venting into a building's attic, designed to circulate air in an entire house or other building. The fan removes hot air from the building and draws in cooler outdoor air through windows and other openings.
Window fans are designed to fit into open windows, and often have expandable side panels to cover the entire window opening. Most units have either one large fan, or two small fans mounted side by side. [1] Most window fans have two or three speeds, and some are electrically reversible so that the user can switch between intake and exhaust modes.
The main goal was to make ventilative cooling an attractive and energy efficient cooling solution to avoid overheating of both new and renovated buildings. The results from the Annex facilitate better possibilities for prediction and estimation of heat removal and overheating risk – for both design purposes and for energy performance calculation.
A radiator is a device that transfers heat to a medium primarily through thermal radiation.In practice, the term radiator is often applied to any number of devices in which a fluid circulates through exposed pipes (often with fins or other means of increasing surface area), notwithstanding that such devices tend to transfer heat mainly by convection and might logically be called convectors.
Air conditioners vs. fans? Sometimes it's best to stick with a fan, but anything over 95°F needs to be cooled with an air conditioner.
Cooling delivered through the floor makes the most sense when there is a high amount of solar gain from sun penetration, because the cool floor can more easily remove those loads than the ceiling. [13] Chilled slabs, compared to panels, offer more significant thermal mass and therefore can take better advantage of outside diurnal temperatures ...
An oil heater, also known as an oil-filled heater, oil-filled radiator, or column heater, is a common form of convection heater used in domestic heating. Although filled with oil , it is electrically heated and does not involve burning any oil fuel ; the oil is used as a heat reservoir (buffer).
The terminal reheat system cools the air in the air handling unit down to the lowest possible needed temperature within its zone of spaces. This supplies a comfortable quality to the space, but wastes energy. The mixed air system has two air streams, typically one for the coldest and one for the hottest needed air temperature in the zone.
