CONTROL METHOD OF TEMPERATURE REGULATION EFFECT BY UTILIZING TEMPERATURE SENSORS DISPOSED AT BOTH OF SENDING SIDE AND RETURNING SIDE OF CIRCULATION-TYPE TEMPERATURE REGULATION DEVICE

摘要

PPROBLEM TO BE SOLVED: To solve problems in a conventional circulation-type temperature regulation device where temperature regulation effect is adjusted on the basis of parameters such as a flow rate of a circulated medium and PID inside of the device, that the temperature regulation effect of the temperature regulation device cannot be flexibly set, the device has poor adaptability to changing load and a temperature region of wide range, and the temperature regulation devices of various performances must be respectively used to various requests for temperature regulation. PSOLUTION: Two sensors are respectively disposed at a sending side and a returning side of a circulation circuit, and the information of two sensors are calculated based on a temperature regulation coefficient F to calculate a reference temperature provided to the temperature regulation device, thus the temperature regulation effect can be adjusted higher or lower than designed temperature regulation performance without changing the temperature regulation parameters such as PID of the temperature regulation device and a circulation flow rate, and the device can cope with dynamic temperature load and the temperature region of wide range by controlling the coefficient from a control device of high order. Further the coefficient F is relate to only the temperature regulation effect and is not relate to temperature regulation accuracy. PCOPYRIGHT: (C)2008,JPO&INPIT
