Then, a heat equalizing member 76 (for example, a heat equalizing sheet or heat equalizing plate) is disposed on the surface side (upper surface side) of the first floor heating panel 4 (second floor heating panel 8) installed. The first floor finish 78 (second floor finish 79) is disposed on the surface side (upper surface side) of the member 76, and the floor is finished in this manner.

この形態では、第１温水チューブ２２（第２温水チューブ２４）はＵ字状均熱部材８０で覆われており、第１温水チューブ２２（第２温水チューブ２４）からの熱の一部は、均熱部材７６に直接的に伝達されるとともに、その残部はＵ字状均熱部材８０を介して均熱部材７６に伝達され、この均熱部材７６を介して第１床仕上げ材に７８（第２床仕上げ材７９）に伝達される。尚、均熱部材７８及びＵ字状均熱部材８０としては、例えばアルミニウム箔などを用いることができる。   In this embodiment, the first warm water tube 22 (second warm water tube 24) is covered with the U-shaped heat equalizing member 80, and part of the heat from the first warm water tube 22 (second warm water tube 24) is While being directly transmitted to the heat equalizing member 76, the remaining portion is transmitted to the heat equalizing member 76 via the U-shaped heat equalizing member 80, and 78 (the first floor finish) via the heat equalizing member 76. It is transmitted to the second floor covering 79). As the heat equalizing member 78 and the U-shaped heat equalizing member 80, for example, aluminum foil can be used.

この床暖房システムでは、第１室２（第２室６）の床を暖房するときには、熱源機２６の第１温水供給系２８（第２温水供給系３０）からの温水が第１床暖房パネル４（第２床暖房パネル８）に供給される。即ち、熱源機２６の第１温水供給系２８（第２温水供給系３０）からの温水が第１供給流路３２（第２供給流路３６）、第１床暖房パネル４（第２床暖房パネル８）の第１温水チューブ２２（第２温水チューブ２４）及び第１戻り流路３４（第２戻り流路３８）を通して循環される。   In this floor heating system, when heating the floor of the first chamber 2 (the second chamber 6), the hot water from the first hot water supply system 28 (the second hot water supply system 30) of the heat source machine 26 is the first floor heating panel 4 (the second floor heating panel 8). That is, warm water from the first warm water supply system 28 (second warm water supply system 30) of the heat source unit 26 is the first supply flow passage 32 (second supply flow passage 36), the first floor heating panel 4 (second floor heating panel) It circulates through the 1st warm water tube 22 (2nd warm water tube 24) and the 1st return channel 34 (2nd return channel 38) of panel 8).

そして、この温水が第１温水チューブ２２（第２温水チューブ２４）を流れる間に、この温水からの熱の一部が均熱部材７６（及びＵ字状均熱部材８０）を介して第１床仕上げ部材７８（第２床仕上げ材７９）に伝達され、このように伝達される熱によって第１床仕上げ材７８（第２床仕上げ材）の表面が暖房される。また、この温水からの熱の残部は、第１パネル本体１０（第２パネル本体１６）を介して第１蓄熱搬送手段１４（第２蓄熱搬送手段１８）に伝達され、その第１搬送チューブ４０（第２搬送チューブ４２）を介して潜熱蓄熱液体に蓄熱される。この潜熱の蓄熱は、水及び潜熱蓄熱材に蓄熱され、特に潜熱蓄熱材が第１温水チューブ２２（第２温水チューブ２４）からの熱を蓄熱する際に固相から液相に変化し、この相変化によって多くの潜熱を蓄熱することができる。   And while this warm water flows through the 1st warm water tube 22 (the 2nd warm water tube 24), a part of the heat from this warm water passes through the heat equalizing member 76 (and the U-shaped heat equalizing member 80). The heat transferred to the floor finish 78 (second floor finish 79) and thus transferred heats the surface of the first floor finish 78 (second floor finish). Further, the remaining part of the heat from the hot water is transmitted to the first heat storage transport means 14 (second heat storage transport means 18) through the first panel main body 10 (second panel main body 16), and the first transport tube 40 thereof. Heat is stored in the latent heat storage liquid via the (second transfer tube 42). The heat storage of the latent heat is stored in water and a latent heat storage material, and in particular, when the latent heat storage material stores heat from the first warm water tube 22 (second warm water tube 24), it changes from solid phase to liquid phase A lot of latent heat can be stored by the phase change.

また、第１室２（又は第２室６）の床を暖房しながらその熱を利用して第２室６（又は第１室２）を暖房するときには、上述したように、熱源機２６の第１温水供給系２８（又は第２温水供給系３０）からの温水を第１床暖房パネル４（又は第２床暖房パネル８）に供給し、この温水供給状態において、循環ポンプ４４を作動させればよい。   Further, when heating the second chamber 6 (or the first chamber 2) using the heat while heating the floor of the first chamber 2 (or the second chamber 6), as described above, The hot water from the first hot water supply system 28 (or the second hot water supply system 30) is supplied to the first floor heating panel 4 (or the second floor heating panel 8), and the circulation pump 44 is operated in this hot water supply state. Just do it.

循環ポンプ４４を作動させると、潜熱蓄熱液体が第１床暖房パネル４（又は第２床暖房パネル８）の第１搬送チューブ４０（又は第２搬送チューブ４２）、第１移送流路４６（又は第２移送流路４８）、第２床暖房パネル８（又は第１床暖房パネル４）の第２搬送チューブ４２（又は第１搬送チューブ４０）及び第２移送流路４８（又は第１移送流路４６）を通して循環される。   When the circulation pump 44 is operated, the latent heat storage liquid is transferred to the first transfer tube 40 (or second transfer tube 42) of the first floor heating panel 4 (or second floor heating panel 8), the first transfer flow path 46 (or Second transfer flow channel 48), second transfer tube 42 (or first transfer tube 40) of second floor heating panel 8 (or first floor heating panel 4), and second transfer flow channel 48 (or first transfer flow) It is circulated through passage 46).

このとき、潜熱蓄熱液体が第１床暖房パネル４（又は第２床暖房パネル８）を通して流れる間においては、第１温水チューブ２２（又は第２温水チューブ２４）を流れる温水からの熱が潜熱蓄熱液体に蓄熱され（この蓄熱の際に、潜熱蓄熱材は固相から液相に相変化する）、またこの蓄熱された潜熱蓄熱液体が第２床暖房パネル８（又は第１床暖房パネル４）を通して流れる間においては、潜熱蓄熱液体に蓄熱された潜熱が放出され（この放熱の際に、潜熱蓄熱材は液相から固相に相変化する）、この放熱された熱が第２パネル本体１６（又は第１パネル本体１０）、Ｕ字状均熱部材８０及び均熱部材７６を介して第２床仕上げ材７９（又は第１床仕上げ部材７８）に伝達され、これによって、潜熱蓄熱液体に蓄熱された潜熱を利用して第２室６（又は第１室２）の床を暖房することができる。   At this time, while the latent heat storage liquid flows through the first floor heating panel 4 (or the second floor heating panel 8), the heat from the warm water flowing through the first warm water tube 22 (or the second warm water tube 24) is latent heat storage The heat is stored in the liquid (at the time of this heat storage, the latent heat storage material changes in phase from the solid phase to the liquid phase), and the stored latent heat storage liquid is the second floor heating panel 8 (or the first floor heating panel 4) The latent heat stored in the latent heat storage liquid is released while flowing through (the latent heat storage material phase-changes from liquid phase to solid phase at this heat release), and the released heat is the second panel main body 16 (Or first panel body 10), is transmitted to the second floor finish 79 (or first floor finish 78) via the U-shaped heat equalizing member 80 and the heat equalizing member 76, thereby providing a latent heat storage liquid The second using the stored latent heat A bed of 6 (or the first chamber 2) can be heated.
