return air or compare the enthalpy of the air, which is typically done in high moisture climates and it triggers more of a concern. In both instances, the outside air must be less energised than the return air for the system to go into the economiser setting. In the United States a repaired, main, "all-air" air-conditioning system (much more frequently called packaged systems) with mixed outdoor condenser/evaporator devices are generally set up in residences, workplaces, and public buildings throughout building and construction, nevertheless because they call for a network of huge duct throughout the structure they are really tough to retrofit (mount in a structure that was not developed to receive it).
