Project Presentation

The project has been carried out by 4 MSc students between February and April 2011 with the aim of trying to develop an understanding of the potential of CO2 heat pumps in the UK. CO2 offers a natural alternative to conventional refrigerants used in Heat Pumps. However, their performances seem sometimes to be lower than the estimation given by the manufacturers. This project will try to understand why, with the particular case study of the Sanyo eco cute system.

The project was broken down into different elements with each student focussing on particular parts and reporting back to the group and advisor during regular meetings. These different aspects of the project were:


By undertaking the project in this manner we hoped to reach these main objectives

  • To understand the specific details of the CO2 refrigerant cycle
  • To understand the dynamics of the whole Sanyo Eco Cute system
  • To monitor and analyse existing installations
  • To develop a model of the CO2 Heat Pump

Through reaching the objectives set out at the start of our project we have been able to deliver:

  • An analysis of different installations in operation
  • A website to present our project
  • A model of a CO2 heat pump system for further implementation in Esp-r

The project was carried out in conjunction with the University of Strathclyde and a number of industrial contacts whose details can be found here .
