Topic Brief - Stop the Waste: Using Industrial Heat Pumps to Rethink Thermal Loads

Select a boiler and steam distribution system to deliver the summed thermal output (plus a margin of safety) at the highest quality required in the plant. [...] A new design approach for thermal systems with IHPs IHP manufacturers/suppliers and engineers familiar with IHP system design are now advocating a different thermal system approach that reduces both wasted energy and costs of the system. [...] Size a baseload IHP system to deliver the lower thermal quality, usually in the form of pressurized water, to meet the balance of plant requirements. [...] Bridging the knowledge gap of how to design for IHPs entails comprehensive assessment of the thermal demands and loads on a granular level, where the engineer understands the real temperature levels, hot-water needs, and energy balances of a particular plant or process. [...] The new IHP system had a coefficient of performance3 of 4.1, achieved an energy savings of 37%, and reduced GHG emissions by 2 An IHP is an electrically or mechanically driven system that moves heat using the same cycle as a refrigerator or domestic HP, that is, evaporation of a working fluid to draw in heat, compression of vapor for transfer, condensation to release heat, and expansion to prepare.
