摘要： An absorption chiller includes a heating medium supply pipe configured to supply a heating medium from a heating medium pipe to a cooling water pipe; a cooling water discharge pipe configured to discharge a cooling water from the cooling water pipe to the heating medium pipe; a control valve provided on the heating medium supply pipe and the cooling water discharge pipe, respectively; and a controller configured to cause the control valve to be opened and to cause the heating medium in the heating medium pipe to be introduced into the cooling water pipe, when a temperature detected by a cooling water temperature detector is equal to or lower than a predetermined temperature, in a wet lay-up state including a state in which a cooling water inlet shut-off valve and a cooling water outlet shut-off valve are closed and the cooling water pipe is filled with the cooling water.

摘要： A heat exchanger includes: a first heat transfer tube unit including first heat transfer tubes arranged in parallel along a first direction within a horizontal plane; and a second heat transfer tube unit including second heat transfer tubes arranged in parallel with one another along a second direction that intersects the first direction within the horizontal plane. Each of the first heat transfer tubes and the second heat transfer tubes includes: straight portions arranged in parallel in a vertical direction; and one or more curved portions that make end portions of the straight portions communicate with each other. The straight portions of the first heat transfer tube unit and the straight portions of the first heat transfer tube unit are stacked on each other alternately.
