These heat pumps are added-in because the storage serves as a warmth sink when the system remains in air conditioning (as opposed to billing) mode, creating the temperature to progressively increase during the air conditioning season.

return air or compare the enthalpy of the air, which is commonly performed in high moisture environments and it triggers more of a problem. In both cases, the outside air has to be less energetic than the return air for the system to enter the economiser setting. In the United States a repaired, central, "all-air" air-conditioning system (extra frequently called packaged systems) with combined outdoor condenser/evaporator units are normally installed in homes, workplaces, and public buildings throughout construction, nevertheless because they need a network of huge air ducts throughout the building they are really difficult to retrofit (set up in a structure that was not designed to get it).
