CONSTITUTION:The heat energy of hot water, water, or the like is supplied to an air conditioning equipment 1 from a heat storage equipment 2. A detector 3 detects the quantity of heat energy, namely, plural heat loads of the supply water flow rate, the returned water temperature, etc., supplied from the heat storage equipment 2 to the air conditioning equipment 1. Each heat load detected by this detector 3 is inputted to an arithmetic unit 11 through an input device. Information of weather actual results and weather forecast is inputted to the arithmetic unit 11 through an input/output device 6 by an operator, and the forecasted heat load calculated by the arithmetic unit 11 is outputted to a display device 7. A heat storage plan operation device 8 determines the heat loads of the quantity of water, the quantity of hot water, etc., to be stored in the heat storage equipment 2 in accordance with a heat load forecast pattern and gives a start/stop command to the heat storage equipment 2 based on the heat storage load.

摘要： PURPOSE:To provide a high reliability prediction controller of a heat source apparatus by providing number of heat sources control means of the heat source apparatus based upon a heat storage scheduled device yielded by heat storage plant operation scheduling means and measured signals. CONSTITUTION:A prediction controller 2 comprises a process input/output part 21, thermal load result storage means 22, thermal load prediction means 23, plant operation scheduling means 24, number of heat sources control means 25. Thermal load is measured from the temperature and flow rate of circulation water and is processed as a thermal load result through the process input/output part 21 and is further stored in the thermal load result storage means 22. Further, a prediction value of the thermal load corresponding to that after N hours is yielded in the thermal load prediction means 23 based upon the foregoing thermal load result. This allows a heat storage schedule target value to be yielded in the heat storage plant operation scheduling means 24 using the capacity of the heat storage vessel 1 and rated capability of a heat source apparatus. Moreover, in the number of heat sources control means 25 the amount of stored heat yielded from a heat storage temperature measurement value in conformity with the heat storage schedule target value is inputted as a feedback signal for on/off control of the heat source device. Thus, a high reliability prediction controller of the heat source apparatus is yielded.

摘要： PURPOSE:To control water-delivery per prescribed time at one supply point to prescribed contracted water-delivery by calculating the scheduled value of the water-delivery in a flow control mode time band from the result of the water-delivery and the contract water delivery in a pressure control time band. CONSTITUTION:A data setter 21 sets timing for switching control modes concerning the pressure control and flow control of water to be distributed from a water pipe 6 in a supply source B to a water pipe network 4, pressure control target value and contracted water-delivery. An arithmetic unit 23 is equipped with a contract flow demand monitoring means 23a and a flow target value calculating means 23b and based on information from an input device 22 collected from the water pipe 6, the scheduled value of the water-delivery in the flow control mode time band is calculated from the contracted water-delivery and the water-delivery in the pressure control time band. Then, the flow target value is calculated as well. This flow target value is transmitted to a controller 27 and the opening degree of a control valve 7 is controlled. Thus, the water- delivery per prescribed period to be supplied form one supply spot in multiple pouring institutes can be limited to the contracted water-delivery.

摘要： PURPOSE:To improve the sewage treatment efficiency by estimating a flow quantity of the sewage per specified cycle with the measured water level and the discharging quantity to automatically form a discharging flow quantity pattern. CONSTITUTION:In a pump control device 11 of a sewage treatment pump equipment 1, a discharging flow quantity pattern computing unit 19 estimates and computes a flowing quantity of the sewage per specified cycle with the water level and the discharging flow quantity detected by a water level gauge 9 of a pump well 4 and a discharging flow quantity meter 10 for detecting a discharging flow quantity from a pump 6 to a sewage treatment equipment 8. A flowing quantity pattern is renewed with this estimation-computed flowing quantity. A flowing quantity pattern is computed with a flowing quantity pattern after a renew, and this pattern is stored in a discharging flow quantity pattern memory 20. A pump drive control unit 21 reads out the discharging flow quantity pattern stored in the memory 20, and controls each pump 6 through a process input/output treatment unit 12 so that the discharging flow quantity detected by the discharging flow quantity meter 10 coincides with the discharging flow quantity of the cycle, to which the actual time belongs, within the discharging flow quantity pattern.

摘要： PURPOSE:To hold the water pressure at a specific point within an allowable range by providing a process value detecting means, a distribution flow rate forecasting means, a water pressure arithmetic means, a control point water pressure target value arithmetic means, and a supply water pressure adjusting means. CONSTITUTION:A water pressure detector 14 and a passing flow rate detector 16 of control valves 4a and 4b are provided at each point in a distributing pipe network 3 to detect the process value. An arithmetic and control unit 23 stores set and changed values from a parameter setter 21 in a data base 23b, and a distribution flow rate forecasting means 23a forecasts a future distribution flow rate. A water pressure arithmetic means 23b determines the water pressure target value schedule at a control point, which rationalizes the water pressure at each point in the distributing pipe network 3, based on the forecasted value. An interface means 23c refers to a control rule to operate a control point water pressure target value based on the process value and the water pressure target value schedule. An output device 24 adjusts the quantity of supply water of the control valves 4 so that the water pressure is the control target value obtained through a controller 25 of control valves, thus holding the water at the specific point within the allowable range.

摘要： PURPOSE:To most suitably suppress the occurrence of cavitation by determining a ratio of degrees of opening of valves to control valves so that cavitation coefficients of respective valves are kept uniform in a controller. CONSTITUTION:A pressure controller consists of a distributing reservoir 1 where drinking water is stored, a reduction valve 2 which controls the pressure of water distribution, a reduction valve 3 connected in series to the valve 2, and a controller 4 which issues a valve opening degree command so that a ratio of degrees of opening of valves 2 and 3 accords with a flow rate. This controller 4 calculates manipulated variables of reduction valves 2 and 4 by signals of a pressure gauge 5 and a flow meter 6 and issues such commands that respective valves 2 and 3 most suppress the occurrence of cavitation. When the occurrence of cavitation is most suppressed, cavitation coefficients of valves 2 and 3 are equal to each other. Then, the degree of opening of the reduction valve 2 is determined by pressure data inputted from the pressure gauge 5, and the degree of opening of the reduction valve 3 is determined by said degree of opening and flow rate data of the flow meter 6, and operation commands are outputted to valves 2 and 3.

Further, the direction and speed of wind are measured by a wind-speed measuring means 20, and the measured values are given to the preprocessing means 30. Then, the preprocessing means 30 prepares the control index for estimating the contamination concentration value and wind-speed value as a fuzzy set to provide it to a fuzzy inferring means 40. Thereafter, the fuzzy inferring means 40, referring to the data inside a fuzzy rule base 41, the result of fuzzy logic based on the control index is output to be given to a ventilation control means 50. Further, the ventilation control means 50 obtains both the demands for the jet-fan operation number and for the wind quantity of dust-collector, and the command values are given to a ventilation means 200 to carry out the control.
