Title:
FLUID HEATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/087643
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 heater core (23) for heating air by exchanging heat between the fluid in the second fluid circuit and air blown into a space to be air-conditioned; 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. The control unit subjects the second heat source to a feedback control based on the temperature of the fluid heated by the second heat source, and in response to the feedback control results, performs a control for minimizing output as the heating load decreases. As a result, it is possible to improve passenger comfort and reduce the energy consumed by heating.
