Title:
RANKINE CYCLE SYSTEM AND CONTROL METHOD FOR RANKINE CYCLE SYSTEM
Document Type and Number:
Japanese Patent JP2018013046
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a Rankine cycle system capable of quickly adjusting a rotational frequency of a pump for working fluid to enable driving at a proper flow rate of working fluid, even in a case where a state of a heat source configured to supply heat to an evaporator of the Rankine cycle system fluctuates, and provide a control method for the Rankine cycle system.SOLUTION: A control method for a Rankine system comprises: calculating an initial pump rotational frequency value Nps corresponding to a state of a heat source G for each initial value update time, in controlling a pump rotational frequency Np of a pump for working fluid of a Rankine cycle system 10; setting the initial pump rotational frequency Nps as an initial value Ns of the pump rotational frequency Np; and feedback-controlling the pump rotational frequency Np so that overheating degree Sh of working fluid flowing into an expander becomes a preset target overheating degree at a time interval, which is a time for feedback control shorter than the initial value update time.SELECTED DRAWING: Figure 7
