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.
Research and development of CO2 technology has been initiated in many countries around the world. By addressing problem areas common to many of the ongoing research programmes, this project would attract interest from a substantial number of manufacturers and research organisations worldwide.
The main objective of this project was to bring CO2 heat pumping technology closer to commercialisation, by addressing critical issues of both a basic and applied character. It was important to involve industry, particularly manufacturers, as well as research institutes in this process.
The project manager (the so-called Operating Agent) was Norway acting through SINTEF Energy Research. Participating countries in this activitiy were: Japan, Norway, Sweden, Switzerland, UK and the USA.
This project aimed to address unsolved problems and issues. One of the activities was to compile existing information and present it as a concise state-of-the-art analysis in the final report. This analysis, of course, formed also the starting point for work to be done. More information can also be found at the website of Annex 27.
In order to accomplish the project’s objectives, the following activities needed to be completed by either the participants, the manager of the project (the so-called Operating Agent) and the Heat Pump Centre:
Since the start of this project the following publication has been published:
This report contains results from 12 different research projects and an extensive literature survey. The report is a useful information source for all those involved in CO2 technology for heating, cooling, refrigeration and air-conditioning.
