The increase in high-efficiency solutions with natural refrigerants has also translated into significant energy savings; it is estimated that the systems sold during 2018 saved almost 3000 MWh of energy, with nearly 1500 tonnes less CO2 equivalent released into the environment.

There was also a reduction in polluting gas emissions due to refrigerant leaks from low GWP solutions. Carel estimates that its 2018 projects cut environmental emissions by 2500 tonnes of CO2 equivalent compared to R404A solutions of equal capacity.

This represents a net and tangible saving of a total of 4000 tonnes of CO2 equivalent – the equivalent of no cars driving through central London for 20 days.

Carel is contributing to the use of natural refrigerants by developing solutions that simplify their use and increase the efficiency of the system. Matteo Dal Corso, application specialist, Retail Solutions at Carel, explained: “Solutions with natural refrigerants represent the present and no longer the future. Now that the technologies we have developed in recent years are available, it is time to focus on innovative features and services, possible thanks to very advanced devices, already installed and ready.”
