<p>The cooling system is suitable for a room which is separated from the outside by a wall (22), and consists of a carrier plate (3) set in the opening (26) in the wall (22) on which the necessary components are mounted. The plate (3) has two louvred openings for inlet air and an exhaust air opening (12) behind which, a fan is situated (11). The fan (11), expels air from the room so that fresh air enters the inlet louvres and travels via ducts (13) to the floor of the room, the warmer air rising to be expelled once again by the fan (11). The installation is controlled by circuitry that contains a thermostat, a sensor (5) mounted on the outer surface of the plate (3) and a sensor (9) on the inner surface. If the set temp. required for the room is exceeded, the thermostat closes and if the outer temperature sensor (5) registers a lower temperature than the inner sensor (9), a relay is closed and the fan (11) starts to expel the warm air until a balance is once again reached.</p> |
