Solutions with small storage spaces can be hybrid, utilizing free air conditioning at the begin of the warmer period prior to switching to a heat pump to further chill the blood circulation coming from the storage space later on in the season. These heatpump are added-in since the storage space functions as a heat sink when the system is in air conditioning (in contrast to billing) setting, triggering the temperature to slowly boost throughout the cooling period.


return air or compare the enthalpy of the air, which is typically done in high moisture environments and it creates more of a concern. In both situations, the outdoors air should be much less energised than the return air for the system to get in the economiser mode. In the USA a dealt with, central, "all-air" air-conditioning system (extra often called packaged systems) with combined outdoor condenser/evaporator units are usually mounted in houses, workplaces, and public buildings during building and construction, however since they call for a network of huge air ducts throughout the building they are extremely difficult to retrofit (install in a building that was not developed to get it).
