Abstract

A ventilation system for a warehouse or other location where central heating is not required, employs a fan located in a conduit with a flap at the inside end. A pair of resistance type thermometers, one (1) outside the building and the second (2) inside, are connected to an amplifier (3) and a changeover device (4) is connected to a relay (5), so that when the interior is hotter than the air outside, the fan motor (6) is started up, and the flow of air lifts the flap (7) and enters the building. When the inside temperature falls, the motor is stopped. The system can be combined with other measuring instruments (9, 10).
