return air or contrast the enthalpy of the air, which is typically done in high moisture environments and it creates more of an issue. In both instances, the outside air has to be less energised than the return air for the system to enter the economiser setting. In the USA a repaired, main, "all-air" air-conditioning system (extra frequently called packaged systems) with combined outside condenser/evaporator units are typically mounted in residences, offices, and public buildings during building, nevertheless due to the fact that they call for a network of huge duct throughout the structure they are extremely tough to retrofit (mount in a structure that was not made to receive it).
