Equipments with little storages can be hybrid, making use of free air conditioning at the beginning of the warmer season before switching over to a heatpump to further cool the blood circulation originating from the storage later on in the season. These heatpump are added-in due to the fact that the storage acts as a heat sink when the system remains in cooling (instead of charging) mode, creating the temperature to gradually increase during the air conditioning period.


In both instances, the outside air should be much less energetic than the return air for the system to enter the economiser mode., and public structures during construction, nevertheless because they call for a network of large air ducts throughout the building they are extremely hard to retrofit (mount in a building that was not made to obtain it).
