Development of triple-effect absorption chiller-heater.

Author(s) : MORI K., OKA M.

Summary

Reducing energy consumption in air conditioning systems has become an urgent issue in recent years, and the efficiency of the absorption chiller-heater systems widely used in office buildings and other facilities needs to be improved. The Japan Gas Association and four manufacturers of absorption chiller-heater systems, at the request of the New Energy and Industrial Technology Development Organization (NEDO), developed a commercially viable version of a triple-effect absorption chiller-heater. The prototypes produced by all four companies have achieved a cooling COP of 1.60, a major improvement in energy efficiency compared to current double-effect systems. The durability of these systems is now being evaluated, and the results will be used to develop a commercially viable triple-effect system.
