Server room air conditioning / computer room / coms room

Server room air conditioning / computer room / coms room: "It is advised when purchasing air conditioning units for server rooms to have energy efficient inverter systems. Generally server room air conditioning will run 24 hours / 7 days a week and the inverter will save energy and equipment failure. Generally cooling is only required but in the UK most air conditioning units are heat pumps which heat and cool. All server rooms and COMS equipment give off a lot of heat and need to be constantly cooled"
