Temperature balancing method for reversing heat exchangers |
摘要 |
Disclosed is a new and improved method for automatically balancing the temperature of a plurality of reversing heat exchanger units provided in parallel relation with each other. The balancing method comprises the steps of: detecting the temperature in portions of each core of the reversing heat exchangers whenever the flow paths of a feed stream and a heat medium stream are changed over, calculating a mean temperature of each core from the said detected values during the most recent certain changeover period from the current time point, calculating a mean temperature for all exchangers from the said calculated mean temperatures of each core, calculating deviation and deviation trend in temperature of respective exchangers depending on a difference between the mean temperature of each core and the mean temperature of all exchangers, feeding back a system deviation in dependence on the said deviation and deviation trend to control valves for balancing the temperature of reversing heat exchangers.
