Solutions with small storages can be hybrid, utilizing complimentary air conditioning at the beginning of the warmer season before changing to a heatpump to further chill the flow coming from the storage later on get more info in the period. These heat pumps are added-in due to the fact that the storage space acts as a heat sink when the system remains in cooling (as opposed to charging) setting, causing the temperature to slowly enhance throughout the cooling period.


In both cases, the outside air needs to be much less energetic than the return air for the system to go into the economiser setting., and public buildings throughout building and construction, however since they call for a network of huge air ducts throughout the building they are really challenging to retrofit (set up in a structure that was not designed to receive it).
