Abstract:
A process for regulating air temperature in an incubator, which accommodates a patient, can be closed, is transparent to heat radiation and is exposed to radiation of a heat radiation source, with an air temperature sensor in the incubator and with an evaluating and control unit, which evaluates signals received from the air temperature sensor and controls a radiation dose delivered by the heat radiation source, the process comprising the steps of:sensing the air temperature with the air temperature sensor to provide an actual air temperature value TI and sending the actual air temperature value to the evaluating and control unit; comparing with the evaluating and control unit the actual value TI with an internally preset set point TS for the air temperature, forming a difference TSâˆ’TI from the two values and generating a manipulated variable from the difference TSâˆ’TI for the heat radiation source; increasing the radiation dose of the heat radiation source if TSâˆ’TI>0; and decreasing the radiation dose of the heat radiation source if TSâˆ’TI<0, the radiation dose of the heat radiation source is reduced until TSâˆ’TI=0 is reached.
