Equipments with small storage spaces can be hybrid, using cost-free cooling at the beginning of the warmer period before switching to a heatpump to more chill the blood circulation coming from the storage space later in the period. These heat pumps are added-in due to the fact that the storage functions as a heat sink when the system is in cooling (rather than billing) mode, creating the temperature to slowly raise during the air conditioning period.

In both instances, the outdoors air should be much less energetic than the return air for the system to go into the economiser mode., and public buildings throughout construction, nonetheless due to the fact that they require a network of huge air ducts throughout the building they are extremely difficult to retrofit (set up in a building that was not developed to get it).
