return air or contrast the enthalpy of the air, which is typically done in high moisture climates and it creates more of a concern. In both situations, the outside air needs to be much less energetic than the return air for the system to get in the economiser mode. In the USA a fixed, central, "all-air" air-conditioning system (much more regularly called packaged systems) with mixed outdoor condenser/evaporator units are typically mounted in houses, offices, and public structures throughout construction, nevertheless since they call for a network of large air ducts throughout the structure they are very challenging to retrofit (mount in a building that was not developed to get it).
