Industrial Heat Pumps

Industrial heat pumps, using waste process heat as the source, deliver heat at a higher temperature for use in industrial process heating, preheating, or space heating. There is debate over their definition, but, in general, they represent a worthwhile method of improving the energy efficiency of industrial processes and reducing primary energy consumption.

Industrial heat pumps (IHPs) offer various opportunities in all types of manufacturing processes and operations. Increased energy efficiency is certainly their most obvious benefit, but few companies have realised the untapped potential of IHPs in solving production and environmental problems. This Application Note demonstrates that IHPs can offer the least-cost option for removing bottlenecks in production processes and allowing greater product throughput and, in fact, may be an industrial facility’s best way of significantly and cost-effectively reducing combustion-related emissions.

I am interested to know whether the technology described is commercially available ; especially, the Li-Br Absorption heat pump, with a temperature lift of 90 deg c & minimum temperature of 10 deg c.

A list of the heat pump manufacturers with their contact details would also help.

With regards

Dear Pieter-Jan:

Thank you.

I hope I will find the relevant information at the company websites.

P.S: I too think that the temp lift of 90 deg c is very high.

Following (Japanese) manufacturers are known to me: Sanyo and Ahlstrom/Rinheat. Case studies exist which were more or less successfull (paper industry, chemistry, refineries). I think, if you visit their websites, you will find more info. May I however add that a temperature lift of 90°c is a lot...

Good luck with you search!

  • Each type of heat pump has different operating characteristics and different temperature ranges
  • Technical and economic process criteria determine the most suitable type for a particular application
  • The initial procedure should identify a few possible installation alternatives, so that the detailed project calculations can concentrate on a limited number of options
  • It is crucial to investigate possibilities for decreasing the installation costs, as they directly influence the payback period
