Abstract (en)
[origin: EP3220061A1] A fluid circulation system with which situations in which inflowing high-temperature fluid causes damage to an indoor-heating device or an increase in room temperature that is not desired by a user can be reliably prevented is provided. A fluid circulation system includes: a heat accumulating circuit in which a fluid circulates between a fluid heater and a heat storage tank; an indoor-heating circuit in which the fluid circulates between the fluid heater and an indoor-heating installation; a valve for switching between the heat accumulating circuit and the indoor-heating circuit; an outflow temperature sensor for detecting a temperature of the fluid flowing out of the fluid heater; and a controller for controlling switching between the heat accumulating circuit and the indoor-heating circuit. The controller is configured to switch, when a request to switch from the heat accumulating circuit to the indoor-heating circuit is issued during a heat accumulating operation in which the heat accumulating circuit is operated, from the heat accumulating circuit to the indoor-heating circuit on condition that the temperature of the fluid flowing out of the fluid heater is lower than a reference value.
