Summary

This paper describes the design and experimental analysis of a steam producing industrial heat pump system. The heat pump is a two-stage flooded system with a thermal capacity of 150 kWout, capable of producing medium pressure steam (4.8 barabs, 150°C) with up to 90°C temperature lifts. The heat pump takes up heat at two distinct temperature levels and in this way can take advantage of temperature glides, typical of waste heat streams in industrial processes. It has been tested with a single working fluid, namely the hydrocarbon Pentane. The heat pump is tested using a specially designed test rig, capable of simulating conditions typical of numerous industrial processes. Experimental results are presented for various operational conditions (temperatures, powers) using both the single-stage and dual-stage cycle. The heat pump is shown to be capable of producing steam temperatures at the design point of 150°C. The results demonstrate that steam producing heat pumps are a feasible technology option for industrial applications. There are however steps needed for mass uptake, especially related to upscaling powers to the 1-5 MW range.
