摘要： PROBLEM TO BE SOLVED: To provide a flexible mounting structure which can be installed with less constraint in terms of installation place and in which propagation of vibration from large-scaled equipment to the structure is suppressed satisfactorily. SOLUTION: A steel block 18 is supported at a plurality of positions right above a SRC beam 2 of the structure 1 through rubber vibration isolators 17 located thereon respectively. An equipment mounting base 6 upon which an engine and a generator is supported on each steel block 18 through a compression coil spring 19, and an intermediated mass 20 is provided actively controllable on the steel block 18 through an active control device 29. Thereby, the vibration to occur with the drive of engine and generator is transmitted to the equipment mounting base 6 after reducing by the compression coil spring 19. The vibration transmitted to the equipment base 6 is reduced by means of the active control device 29, and then the vibration is further reduced by the rubber vibration isolators 17, and finally the vibration transmitted to the structure 1 is prevented satisfactorily.

摘要： PURPOSE: To prevent the generation of overshoot due to an increase in exhaust heat demand amt. at an exhaust heat recovery part without affected by secular change or a variation in flow resistance. CONSTITUTION: A rapid decrease in exhaust heat demand amt. such as sudden suspension of warm water-absorption type refrigerator operation, etc., is detected from the temp. of cooling water supplied to a heat exchanger for heat radiation by means of an input temp. sensor 16. A control output of 30% is generated from feed forward side control means 22. Control output from a feedback side control means 23 is added to the 30%-control output. The added control output controls a three-way valve 12. Cooling water having some previously set amt., not the total amt. of the cooling water, is supplied to the heat exchanger for heat radiation. When exhaust heat recovery is restarted, the control output from the feed forward side control means 22 is retained to 30% by means of a cooling water temp. sensor 15 until the temp. of the cooling water returned to an engine cooling part becomes set temp. or below. Thus, returning the high-temp. cooling water due to overshoot to the engine cooling part is avoided.

摘要： PURPOSE: To improve reliability of the whole of a system by a method wherein a feedforward signal considering a waste time of the answer of a piping and a valve for radiation from a difference in a quantity of heat between a quantity of heat generated by an engine and an amount of heat absorbed by hot water utilizing equipment is incorporated in a control system to detect the heat source water temperature of an engine inlet and effect feedback control. CONSTITUTION: The inlet temperature of an engine 2 is detected by a temperature sensor 9 and PID computation of a deviation from a set value is effected to control a valve 7. Meanwhile, a rated quantity of a generated heat of an engine 2 is computed by a computing device 12. From the opening of a valve 5 for hot water utilizing equipment 4, a quantity of an absorption heat is computed by utilizing an absorption heat quantity-valve opening characteristic, and from a difference between a rated quantity of a generating heat and a quantity of an absorption heat, a quantity of heat discharged by a radiator 6 is calculated. Based on the quantity of heat, the opening of the valve 7 is decided by utilizing a quantity of the discharge heat-valve opening characteristics of the valve 7. The valve opening signal passes a waste time element, considering the waste time of a piping of which a generation block 20 for a feedforward signal consists and an answer time of the valve 7 and is synthesized and added to a PID computing result.
