return air or compare the enthalpy of the air, which is frequently performed in high humidity climates and it causes even more of a concern. In both click here instances, the outside air must be less energised than the return air for the system to enter the economiser setting. In the United States a fixed, central, "all-air" air-conditioning system (more regularly called packaged systems) with mixed exterior condenser/evaporator units are typically mounted in residences, offices, and public structures throughout construction, however because they require a network of huge air ducts throughout the building they are extremely difficult to retrofit (mount in a structure that was not created to receive it).
