return air or contrast the enthalpy of the air, which is frequently done in high moisture environments and it causes more of an issue. In both cases, the outdoors air should be less energised than the return air for the system to get in the economiser setting. In the United States a dealt with, main, "all-air" air-conditioning system (a lot more frequently called packaged systems) with mixed outdoor condenser/evaporator systems are generally installed in houses, offices, and public structures throughout building and construction, nevertheless due to the fact that they call for a network of large air ducts throughout the building they are extremely hard to retrofit (install in a building that was not made to get it).
