Abstract
A method for the temperature balancing control of a plurality of heat exchangers wherein, in case of operating the heat exchangers connected in parallel, the temperatures of a medium to-be-heated on the outlet sides of the respective heat exchangers are balanced. According to the method, the temperatures of the same positions of the heat exchangers except for the inlets thereof for the medium to-be-heated are sensed, the respective sensed values are compared with a temperature setting value so as to calculate control signals, all the control signals are subsequently revised so that the maximum value among the control signals may agree with a preset control reference value, and temperature regulation means disposed for the respective heat exchangers are controlled on the basis of the revised control signals.
