IEA Heat Pumping Technologies Annex 48: Industrial Heat Pumps, Second Phase (HPT TCP)

The main goal is to overcome still existing difficulties and barriers for the larger scale market in industrial applications. Industrial Heat Pumps (IHPs) offer various opportunities to all types of manufacturing processes and operations. They use waste process heat as the heat source, delivering heat at higher temperatures for use in industrial processes, heating or preheating, and industrial space heating and cooling. IHPs can significantly reduce fossil fuel consumption and GHG emissions in a variety of applications.

Objectives

The Annex will start with a kick-off-meeting discussing and developing the detailed work programme, subdivided in the following tasks:

Task 1: Analysis of the collected Case studies and successful applications of industrial heat pumps,
Task 2: Structuring information on industrial heat pumps and preparation of guidelines
Task 3: Application of existing models for the integration of a heat pump into a process.

Every task has its own Task Leader with specific competence for the specific Task, the work is coordinated under the overall management of the Operating Agent/Annex Manager.

IEA Heat Pump Programme Annex 30: Retrofit Heat Pumps for Buildings (HPP)

The market potential of heat pumps for retrofitting existing buildings is much larger than in new buildings. However, the heat pump market in existing buildings today is small compared with the presently dominating market in new buildings. The new annex should therefore contribute to overcome the technical and market barriers in this interesting market sector.

End date: Spring 2010

Objectives

The objective of annex is a survey of the availability, technology, economy, ecology and possible R&D trends of heat pump systems to retrofit low energy efficient space and tap water heating systems in existing residential buildings, taking into account that heat pumps are able to drastically reduce fossil energy consumption and the related greenhouse gas emissions. Space heating systems include first of all hydronic systems including heat sources, heat pumps and distribution systems but also air-to-air heat pump air-conditioners without heat distribution system. Heat pumps for retrofit should include electric heat pumps with zero or low GWP working fluids and gas-fired systems including ab- and adsorption.
