Mitigation of greenhouse gas emissions from commercial refrigeration systems: what matters?

Author(s) : NEKSÅ P., LUNDQVIST P.

Summary

Mitigation of greenhouse gas emissions from the refrigeration, air conditioning and heat pump sector is a challenge that has to be addressed. In order to understand the possibilities it is useful to divide the emissions into two categories: direct, caused by release of refrigerants into the atmosphere, and indirect, caused by the release of CO2 in power production plants. The most important sectors are commercial refrigeration and mobile air conditioning which together represent about 70% of the total direct greenhouse gas emissions from the refrigeration, A/C and heat pump sector. This presentation concentrates on the discussion to the commercial refrigeration sector. The emission situation and possible alternatives for emission mitigation and their cost are discussed. The relation between the direct and indirect effect varies considerably with factors such as refrigerant choice and charge, leakage rates and the regional power mix. The geographical situation of the country in question is also important. It is therefore difficult to generalize the characteristics of a certain application, for example a supermarket.
