Solutions with tiny storages can be hybrid, utilizing free air conditioning at the beginning of the warmer period before switching over to a heat pump to more chill the flow coming from the storage space later in the period. These heatpump are added-in since the storage space serves as a warm sink when the system remains in cooling (rather than billing) mode, triggering the temperature level to gradually boost throughout the cooling season.


In both situations, the outside air should be less energetic than the return air for the system to enter the economiser mode., and public buildings during construction, nonetheless due to the fact that they call for a network of huge air ducts throughout the structure they are really tough to retrofit (set up in a structure that was not developed to receive it).
