The hydraulic air compressor is an energy converter from hydraulic potential energy to compressed air. It has been widely used in the northern part of the United States, Canada and Europe as a coal mine compressor for 100 years. In the 1970s its performance was studied again for its utilization as a conventional air cooler. As the air bubbles are compressed in a large amount of water by the hydrostatic pressure, it does not need any moving parts and can achieve an isothermal compression. The isothermal compression process needs less energy than the conventional adiabatic one, and it is an attractive method of compression. To study the basic performance, a small test apparatus was constructed. More than 80% efficiency was attained for a wide range of head ratios, which means that it can be applied for both installations to produce a small amount of high-pressure compressed air and a large amount of low-pressure compressed air. Flow losses in various parts were analyzed and given by the experimental equations.
