An indicator detects the temperature in the air flow in or from the room and a control unit controls the flow and temperature of air. The control unit adjusts the input air flow and temperature to the temperature variations in the room in order to maintain the required temperature level. The control unit, on detection of an increasing cooling requirement, successively lowers the input air temperature from a normal level in the direction of a minimum level until the required temperature level is achieved. The air flow is increased from a normal flow to a maximum flow if the input air temperature reaches the minimum temperature. Regulation of the input air occurs by means of a speed-regulated fan. |
