43 % of the residential buildings approved in 2017 were fitted with heat pumps, making these the most popular heating system for the first time, overtaking gas as the leading energy source (source: bwp).
Interesting development in commercial and industrial settings
Virtually no statistics have been gathered regarding the use of heat pumps in commercial and industrial settings. This does not mean, however, that there are no developments of interest to report here, or that they are not being put to successful use. The European Heat Pump Summit in 2017 provided an opportunity for professionals to learn about the many successful applications in many different industries worldwide.
For example, the presentation “Unlocking the Potential” by Madhavan Nampoothiri highlighted the importance of industrial heat pumps in India for the summit participants. By 2025, India will be the world’s third-largest economic region, ahead of Germany. The bulk of India’s power needs are for its industry. There will be a huge potential need for industrial heat pumps in many different industrial segments, with required temperatures expected to reach 100°C, Nampoothiri observes.
Japan – a trail-blazer in industrial heat pump use
The message in the presentations from Japan, Austria, Switzerland, Denmark and France, which highlighted the use of heat pumps in the higher power ranges in commercial and industrial applications also supported the report from India. The use and importance of industrial heat pumps have probably progressed the furthest in Japan.
Japan illustrated an application for the metal-working industry in an automotive supplier plant in which the heat pump can heat and cool simultaneously, and where the various operating settings were adjusted to suit requirements. This solution has already been put into practice in 110 heat pumps used for this application in Japan and other countries.
The utilisation of high-temperature heat pumps is also being driven forward intensively and successfully in Japan. Because of the country’s huge energy requirements and the fact that many of its nuclear power stations are being decommissioned, the pressure to use energy-efficient systems in commercial and industrial applications is a major driver of the use of heat pumps.
Energy transformation is a huge driver – in Europe, too
Industrial heat pumps are also experiencing very satisfactory progress in Austria: 62 examples from more than 160 existing plants have already been documented.
The presentation on high-temperature heat pumps includes an overview of the manufacturers and their programmes. The data that has been gathered on the temperatures needed in the various applications is also of interest.
What is the situation in Germany?
“In Germany, in particular, the low price for gas and the high electricity price are tending to slow the rate of growth in the commercial and industrial use of heat pumps,” observes Dr Rainer Jakobs, Operating Agent of IEA-HPT Annex 48, Industrial heat pumps. “Industrial heat pumps are much more important in other parts of the world than in Germany. But commercial and industrial users and policy-makers in Germany are steadily growing more aware of the benefits to be had from saving energy and costs, and the significant reduction in greenhouse gas emissions, which have been comprehensively demonstrated at the European Heat Pump Summit.”
With the full-day event “Heat Pumping Technologies for Commercial and Industrial Applications”, the Chillventa CONGRESS, held the day before the actual Chillventa exhibition, will offer an up-to-date overview of the market, opportunities and developments for heat pumps in commercial and industrial use.
