This paper discusses that in Japan, absorption refrigerating machines were first manufactured about 20 years ago. Then, a steam absorption refrigerating machine producing chilled water by using steam as heat source was manufactured. By 1965, heavy oil was used in the heating boilers of almost all the buildings in the Tokyo metropolitan district, and air pollution caused by sulfur oxides, exhausted from the boilers, became a serious social problem. For that reason, a gas direct-fired absorption water heater chiller, producing chilled and hot water by direct firing, using city gas, was developed. At the same time the refrigeration cycle was advanced from a single-effect to a double-effect type for energy-saving purposes.
