    摘要: A Refrigeration And Air Conditioning, RAC, system and a method of operating a RAC system. The RAC system is configured to determine a renewable energy supply for powering the RAC system and/or determining a maximum power limit for the RAC system; determine whether the renewable energy supply and/or the maximum power limit are sufficient for operating the RAC system at a current temperature setting; adjust the current temperature setting if the renewable energy supply and/or the maximum power limit are not sufficient for operating the RAC system, wherein adjusting the current temperature setting comprises determining whether a new temperature setting such that the renewable energy supply and/or the maximum power limit are sufficient for operating the RAC system lies within a predetermined temperature range representative of an acceptable user comfort level variation; and generate a notification if the new temperature setting is outside the predetermined temperature range.
