Title: Demand processing method of turbo refrigerating machine
Inventor: HIGO YUZURU
IPC: F25B1/053
Filed: 1990-06-18
Abstract: PURPOSE:To process demand by a method wherein a power after regulation is operated from a power consumption, obtained from a diagram based on either one of the rotating speed of a compressor or the opening degree of a damper and a cooling water temperature, and a power to be regulated, which is obtained from the diagram based on the remaining time of a time interval, then, one of the rotating speed of the compressor or the opening degree of the damper is operated by the diagram. CONSTITUTION:The power consumption W1 of a refrigerating machine at that time point is known by a diagram A based on the rotating speed of a compres sor for refrigerant and the opening degree of a damper at a time of processing a demand. Subsequently, a proper regulating power W2 is known by another diagram B. A regulating target power is obtained by the operation of W1-W2=W3 and, further, the rotating speed of the compressor for refrigerant or the opening degree of the damper for regulating a power to the target power W3 is obtained by the diagram A. According to this method, demand is processed by suppressing the rotating speed of the compressor or reducing the opening degree of the damper without necessitating any knowledge or skill of high degree or without affecting adverse effect on a power supplying facility.
