A Series of this conference was initiated as Absorption Working Fluid Workshop at Stockholm, Sweden in 1980.
It was the first international forum on absorption heat pump/refrigeration technologies, and continued as International Sorption Heat Pump Conference every two to three years by expanding its scope to comparable technologies,such as adsorption heat pump/refrigerators, chemical heat pumps, desiccant air conditioning, sorption energy storage etc.
The conference was held in Tokyo in 1991. After a quarter of a century, this conference will go back to Tokyo.
