That is, the holding member may be stacked along the vertical direction (Z direction).

  Moreover, in the said embodiment, although the neutralizing agent 11 is kneaded into the holding member 7b, this invention is not limited to this. In the present invention, the neutralizing agent may be bonded to the molded holding member.

  Moreover, in the said embodiment, although the neutralizing agent 11 is calcium carbonate, this invention is not limited to this. In the present invention, the neutralizing agent may be an alkaline substance (magnesium hydroxide or caustic soda) that can neutralize acidic condensed water.

  Moreover, in the said embodiment, although the condensed water purification cooler 7 has the fin 7a, this invention is not limited to this. In the present invention, the condensed water purification cooler may not include fins.

  Moreover, in the said embodiment, although the condensed water purification | cooling cooler 7 is making the holding member 7b soak the condensed water DW, this invention is not limited to this. In this invention, the aspect which sprays condensed water on a holding member may be sufficient.

  Moreover, in the said embodiment, although the tank 21 is arrange | positioned at the cooling water circulation circuit part 61 and the condensed water supply circuit part 8, and the mixed condensed water MW is stored, this invention is not limited to this. As shown in FIG. 11, the tank 321 may be disposed only in the condensed water supply circuit unit 308, and the condensed water DW may be stored. Specifically, the absorption heat pump device 301 of the second modified example further includes a condensed water supply circuit unit 308 that connects the heating unit 302 a and the condensed water purification cooler 307 separately from the cooling water circulation circuit unit 361. Yes. In the absorption heat pump device 301, purified condensed water CW that has purified and cooled the condensed water DW generated in the heating unit 302 a using the condensed water purification cooler 307 circulates in the cooling water circulation circuit unit 361. The condensed water purification cooler 307 of the absorption heat pump device 301 purifies the condensed water DW supplied from the condensed water supply circuit unit 308 and purified condensed water CW and condensed water supply circuit unit 308 circulating in the cooling water circulation circuit unit 361. The condensate water DW supplied from is cooled.
