Title:
EXHAUST HEAT RECOVERY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/094118
Kind Code:
A1
Abstract:
This exhaust heat recovery system is provided with: a conveying device for circulating a first coolant; an exhaust heat recovery heat exchanger for recovering exhaust heat from the outside of the system; an exhaust heat supply heat exchanger for exchanging heat with the outside of the system and supplying exhaust heat to the outside of the system; an exhaust heat exchanger for exchanging heat with the outside of the system and exhausting surplus heat inside the system to the outside of the system; and an auxiliary heat exchange device in which a compressor, a first heat exchanger, a throttle device, and a second heat exchanger are sequentially connected through piping, and through which a second coolant circulates, wherein the exhaust heat recovery heat exchanger, the conveying device, the first heat exchanger, the exhaust heat exchanger, the second heat exchanger, and the exhaust heat supply heat exchanger are connected sequentially by piping and allow the first coolant to circulate therein. The auxiliary heat exchange device is provided with a control device, wherein the control device controls the rotation speed of the compressor and the throttle amount of throttle device such that the temperature of the first coolant flowing into the exhaust heat exchanger rises when the temperature of the first coolant flowing through the outflow side of the second heat exchanger is greater than the upper limit of a set temperature range.
