Absorption chiller-heater, replenishing liquid for absorption chiller-heater, absorption liquid for absorption chiller-heater, and maintenance method

A replenishing liquid for an absorption chiller-heater for an absorption liquid used in an absorption chiller-heater, wherein all of:

• 2.0% to 5.2% of a molybdate as a corrosion inhibitor,
• 6.3% to 23% of sodium sulfite or sodium bisulfate as a concentration improving agent, and
• 1.0% to 12% of an octyldimethylethylammonium salt or a lauryldimethylethylammonium salt as a dispersant
• are mixed to produce the replenishing liquid.

An absorption liquid for an absorption chiller-heater used in the absorption chiller-heater, wherein all of:

• 200 ppm to 520 ppm of a molybdate as a corrosion inhibitor,
• 630 ppm to 2300 ppm of sodium sulfite or sodium bisulfite as a concentration improving agent, and
• 100 ppm to 1200 ppm of an octyldimethylethylammonium salt or a lauryldimethylethylammonium salt as a dispersant
• are mixed in a lithium bromide aqueous solution.
