Systems with little storages can be hybrid, utilizing totally free air conditioning at the begin of the warmer season prior to switching over to a warmth pump to additional cool the circulation originating from the storage space later on in the period. These warm pumps are added-in due to the fact that the storage functions as a warm sink when the system remains in cooling (as opposed to charging) setting, triggering the temperature level to progressively raise throughout the air conditioning period.


In both instances, the outdoors air should be less energetic than the return air for the system to get in the economiser mode., and public structures during building and construction, however because they require a network of large air ducts throughout the building they are very difficult to retrofit (set up in a structure that was not made to get it).
