Safe use of flammable refrigerants

In order to achieve the climate neutrality goals and the forthcoming F-gas regulation, it is important to promote the transition toward low-GWP refrigerants.

Almost all low GWP refrigerants are flammable and the safety issues of these refrigerants (hydrocarbons and HFOs) prevent them from being used in larger systems.

This project is a continuation of previously carried out risk assessment projects and the purpose is to develop and improve the knowledge required for the safe use of flammable refrigerants in refrigeration and heat pump systems.

This project will evaluate and quantify the refrigerant concentration around a plant in connection with unintentional emissions.

In addition, the project will evaluate various available technical solutions for detecting refrigerant leakage, and also the solutions and methods to reduce the risk of occurring flammable concentrations. The overall goal is that the results to be used as a basis for developing new national and international standards.
