FAN COIL SYSTEM

WIPO Patent Application WO/2018/193615

A1

This fan coil system is provided with: a heat source machine that generates and conveys a water heat medium which is cold water or hot water; a primary-side fan coil unit that is connected in parallel to the heat source machine through piping and that conditions air by using, as a heat source, the water heat medium from the heat source machine; and a secondary-side fan coil unit that is connected in series to the downstream side of the primary-side fan coil unit through piping and that conditions air by using, as a heat source, the water heat medium from the primary-side fan coil unit. The primary-side fan coil unit is provided with: a primary-side heat exchanger that performs heat exchange between the water heat medium and an indoor air; a flow rate regulating valve that is provided to the inlet side of the primary-side heat exchanger and that regulates the flow rate of the water heat medium; an inlet water temperature detector that detects the inlet water temperature in the primary-side heat exchanger; an outlet water temperature detector that detects the outlet water temperature in the primary-side heat exchanger; and a primary-side control device that controls the opening degree of the flow rate regulating valve according to the difference between the outlet water temperature and the inlet water temperature.
