return air or contrast the enthalpy of the air, which is often performed in high moisture environments and it creates more of an issue. In both situations, the outside air must be much less energised than the return air for the system to go into the economiser mode. In the United States a repaired, main, "all-air" air-conditioning system (much more often called packaged systems) with combined outdoor condenser/evaporator devices are typically installed in residences, workplaces, and public buildings throughout building, however because they need a network of huge duct throughout the structure they are extremely challenging to retrofit (mount in a building that was not made to get it).
