AN ARRANGEMENT FOR THE OPTIMIZED CONTROL OF CHILLED WATER TEMPERATURE

摘要

Arrangement controls best chilled water temperature and is supplied to process, and by pump, water, which is quenched, has compressor and load valve, including the first and second sensors in coolant liquid circulation by coolant liquid, for sensing supply and returning to temperature and process. Value obtains amount of work done, and by pump and compressor, value and water supply and return water temperature value are available to quality monitoring with that. Monitoring operation to generate the function of some reference temperature, but these supply temperatures be above or below the supply temperature ratio depend on work and difference between difference variation supply and return to temperature. When the ratio is about zero, this difference for indicating supply and returning between temperature is in optimal and above-mentioned reference temperature and supply temperature. When the ratio is negative, fiducial temperature is lower than supply temperature and when ratio is positive several fiducial temperatures higher than supply temperature. With reference to be used for temperature controller and the first load valve, if for adjusts setting valve according to load demand signal be selected as or fiducial temperature lack or requirements depending on measure demand necessary to process.
