Japanese Patent JP5836915

B2

PROBLEM TO BE SOLVED: To obtain a filter device for a water heat exchanger capable of capturing a substance to be captured such as an iron rust particle from water flowing into a water circuit of the water heat exchanger while suppressing pressure fluctuations, and easily detecting filter replacement timing.SOLUTION: A water-heater-exchanger filter device 40 includes a first filter unit 2 and a second filter unit 3 provided on an inlet of a water channel 1a of a water heat exchanger 1; a bypass pipe 7 that acts as a bypass of the first filter unit 2 and the second filter unit 3; a pressure loss unit 6 provided at the bypass pipe 7; and a replacement-timing discrimination sensor 8. If the second filter unit 3 is greater than the first filter unit 2 in a pressure fluctuation when a substance to be captured is accumulated pressure losses of the first filter unit 2, the second filter unit 3, and the pressure loss unit 6 before the substance to be captured is accumulated are α, γ, and β, respectively, and pressure losses of the first filter unit 2 and the second filter unit 3 that come to the end of service lives are α' and γ', respectively, (α+γ)<β<(α'+γ') is satisfied.
