Patent ID: 7337623

Claim:
A method for controlling a temperature in a space in an aircraft, wherein the space includes at least one cell, wherein controlling the temperature is performed by means of a heating system with at least one controlling device, and wherein the method comprises: measuring set variables including a first rate of change of a first temperature in a first cell of the at least one cell; calculating control variables for controlling the at least one controlling device on the basis of the measured set variables, wherein calculating the control variables is performed by means of non-linear fuzzy logic within a control circuit with the use of the measured set variables; transferring the calculated control variables to the at least one controlling device; introducing a first air into the at least one cell; and controlling a second temperature of the first air which is introduced into the at least one cell by the at least one controlling device on the basis of the calculated control variables; adjusting first and second air inlet rates of a second air from an air mixer and a third air from a bleed air compressor by means of a trim adjustment valve; heating a fourth air from the trim adjustment valve by means of a heater; and switching to zero of a heat output of the heater if the rate of change in a third temperature in a first air inlet duct upstream of the heater exceeds a certain value.
