The report covers the second year of activity in a program to develop a natural gas engine-driven chiller with a nominal capacity of 150 tons and an optional engine and exhaust waste-heat recovery system totaling approximately 7 therms. The design is based on a conventional vapor-compression cycle, which uses an oil-flooded twin-screw compressor. The compressor is driven at variable speeds by a 454-cubic-inch-displacement automotive engine converted to operate on natural gas. During the period covered by the report, technical development of the chiller has continued, resulting in important improvements in the compressor oil system, component arrangement, microprocessor-based controls, and equipment sound attenuation. Most notably, the first season of a nationwide field test of 6 units was completed with an extensively redesigned chiller. Excellent reliability was obtained through 8600 test hours. A weighted time average COP of 1.44 for the 6 units was measured by means of a telemonitoring data acquisition system.
