Development and demonstration of an electric heat pump for waste-heat recovery in industry. Design and analysis report and analysis report
Abstract
The output capacity of the unit is 30 x 10 to the 6th power Btu/h in the form of process steam delivered at 50 psig with 20 F superheat (318 F). A functional description of the heat pump system is given along with a thermodynamic analysis of the cycle. The various subsystems, controls, and major components are also described and a safety analysis presented. A general discussion of the important considerations involved when considering the application of a heat pump to an industrial process is given. Additional information includes an analysis of the hot gas by-pass and control of the intercooler; pressure drops in methanol piping and heat exchangers; and typical liquid nitrogen storage system information.
