We would like to report regarding the latest absorption chiller-heater, which has reduced energy consumption drastically by increasing efficiency at the partial load by two methods in the following. One of methods is to control the circulated solution flow rate optimally, and the other is to expand the operation range to a lower temperature for cooling water. Furthermore, Absorption chiller-heater has been also optimized for replacement work. The weight of absorption chiller-heater is reduced thoroughly by a new design of high temperature generator, and the replacement work for it is carried out easily and successfully to avoid an additional work such as reinforcement work for the existing foundation.
