Title:
RANKINE CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/010465
Kind Code:
A1
Abstract:
A Rankine cycle device, provided with: a pump for pumping the working fluid; a heat exchanger for exchanging heat between the working fluid pumped by the pump and a fluid from the heat discharge source; an expander for causing the working fluid heat-exchanged by the heat exchanger to expand and outputting the mechanical energy; a condenser for causing the working fluid caused to expand in the expander to condense, the pump, the heat exchanger, the expander, and the condenser being connected in sequence so as to form a working fluid circuit in which the working fluid circulates; a pressure detection device for detecting the low-pressure-side pressure, which is the pressure of the working fluid flowing from the exit of the expander to the entrance of the pump; and a pressure control device for controlling the high-pressure-side pressure, which is the pressure of the working fluid flowing from the exit of the pump to the entrance of the expander. The pressure control device is constituted so as to control the high-pressure-side pressure so that the high-pressure-side pressure remains constant, even if the low-pressure-side pressure decreases, as long as the difference between the high-pressure-side pressure and the low-pressure-side pressure does not exceed a maximum control limit set in advance.
