Open-cycle vapor-compression heat pump. Annual report, April 1983-April 1984
Large quantities of low-grade energy in the form of low-pressure steam and low-temperature heat are wasted by industry. The practical and economical recovery of energy from these sources is often limited by the number of applications for the use of low-temperature heat. Thermo Electron has developed an open-cycle steam-heat-pump system capable of the direct recovery and upgrading of low-grade waste steam. The system compresses low-pressure waste steam (or steam made from sources of low-temperature waste heat) to produce high-pressure steam suitable for use in industrial processes. A prototype system has been developed that is capable of recovering and recompressing up to 10,000 lb/hr of waste steam, while using only 50 percent of the fuel that would be required to produce comparable steam in a boiler. The prototype steam recompression system, using a 2200-cfm rotary screw compressor driven by a 500-hp natural-gas engine, was tested at Thermo Electron and then installed at the Monsanto Company in western Massachusetts for a yearlong field test.
