Projects

HPT TCP has been active since 1978, with a lot of collaborative research, development, demonstration and deployment projects. We formerly called these projects "Annexes". They are conducted on a combination of cost sharing and task-sharing basis by the participating countries. Here you can read about the projects that are running right now.

Retrofit Heat Pumps for Buildings

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. Objectives The objective of annex is a survey of the availability, technology, economy, ecology and possible R&D trends of heat...

Test procedure and seasonal performance calculation for residential heat pumps with combined space and domestic hot water heating

The Annex investigated the testing of the most common combined heat pump systems with heating of domestic hot water by desuperheating subcooling of the condensate cascade hot water heat pump using the heat from the supply line of the heating system Objectives The first objective of the Annex was to work out a test procedure, which provided the necessary data in order to calculate the overall seasonal performance factor of combined heat pump systems with a...

Selected Issues on CO2 as a Working Fluid in Compression Systems

This project focused solely on CO2 as a working fluid in compression systems. The main objective was to bring CO2 heat pumping technology closer to commercialisation, by addressing critical issues of both a basic and applied character. One of the activities was to compile existing information and present it as a concise state-of-the-art analysis in the final report. Objectives The main objective of this project was to bring CO2 heat pumping technology closer to commercialisation, by...

Year-Round Residential Space Conditioning Systems using Heat Pumps

This project aimed to define and demonstrate the technical feasibility of new packaged systems for year-round residential space conditioning using heat pumps. The work included electrically driven compression heat pumps, heating/ventilating and air-conditioning equipment (HVAC) dedicated to the residential sector. Objectives The project aimed to define and demonstrate the technical feasibility of new packaged systems for year-round residential space conditioning using heat pumps. These systems (which include all components used in a heating/ cooling system,...

Absorption Machines for Heating and Cooling in Future Energy Systems

This project, which was concluded in June 1999, aimed to analyse the reasons behind the still limited implementation of absorption technology in heating and cooling. Participants in this project contributed by gathering relevant national information and by participating in two workshops. Its objectives were to gain a better understanding of market opportunities for absorption machines (machines using either absorption or adsorption technology), improve understanding of the technology, and disseminate information. Objectives The objectives of the...

Heat Pump Systems for Single-Room Applications

While heat pumps are sold in increasing numbers in many regions, installations are restricted to certain building types. In particular, relatively few heat pumps are installed in buildings where no ducted air distribution system has been fitted – a significant market sector! A promising option is to use single-room heat pumps. To support their development and installation, the IEA Heat Pump Programme set up an international project known as Annex 23. This project, which was...

Compression Systems with Natural Working Fluids

Most of the substances being considered to replace chlorofluorocarbons (CFCs) and HCFCs as working fluids in heat pumping (heat pump, air conditioning and refrigeration) systems are new synthetic compounds, foreign to nature. Extensive use of such man-made compounds may yield unforeseen environmental effects, as has already been experienced with CFCs and HCFCs. By applying naturally occurring and ecologically safe substances as working fluids, uncertainties and potential negative environmental effects are eliminated. To further develop the...

Global Environmental Benefits of Industrial Heat Pumps

By upgrading heat at a lower temperature, industrial heat pumps use their high-energy efficiency to meet heating needs in industry, therefore helping to reduce the consumption of fossil fuels and the associated emissions of CO2 and other harmful gases such as SOx, NOx, methane and carbon monoxide. This project tried to gain a better understanding of the global energy and environmental benefits of industrial heat pumps, to broaden the knowledge base and disseminate the information....
