ABSTRACT
The diffusion-absorption refrigeration cycle was pioneered around 1920 by two Swedes named Von Platen and Munters (1928). The cycle is unique in that it runs without any mechanical work input. This is achieved by pumping the fluids using a bubble pump driven by heat. Another unique feature of the cycle is that it is essentially noise-free. These two characteristics provide solid niche markets for the cycle in the recreational vehicle and the hotel room refrigerator markets. The cycle has come a long way since its origin and is currently manufactured in numerous locations throughout the world, including Sweden, United States, Mexico, Argentina, China, and India.
