Equipments with little storages can be hybrid, making use of totally free cooling at the beginning of here the warmer period prior to changing to a heatpump to additional cool the circulation originating from the storage later in the period. These warm pumps are added-in because the storage space serves as a warmth sink when the system is in air conditioning (rather than charging) mode, triggering the temperature level to slowly increase throughout the cooling season.


In both cases, the outside air needs to be much less energised than the return air for the system to enter the economiser mode., and public structures during construction, nonetheless because they call for a network of large air ducts throughout the structure they are extremely challenging to retrofit (mount in a structure that was not designed to receive it).
