Title:
FLUID HEATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/087642
Kind Code:
A1
Abstract:
This fluid heating device is equipped with: a first fluid circuit (10) for circulating a fluid to a first heat source (12); a second fluid circuit (20) for circulating the fluid to a second heat source (22); a switching unit (33) for switching the flow of the fluid between a state of connection between the first fluid circuit and the second heat source and a state of disconnection therebetween; and a control unit (40) for controlling the second heat source. While the switching unit has connected the first fluid circuit and the second heat source, the control unit performs a feedback control based on the temperature of the fluid heated by the second heat source, and performs a feed-forward control based on the temperature of the fluid introduced into the second fluid circuit from the first fluid circuit. As a result, it is possible to suppress overly sensitive control reactions.
