Systems with little storage spaces can be hybrid, utilizing complimentary air conditioning at the beginning of the warmer period before changing to a heat pump to more cool the circulation coming from the storage space later in the period. These warm pumps are added-in since the storage space functions as a warmth sink when the system remains in cooling (as opposed to charging) setting, triggering the temperature to progressively increase during the cooling season.


In both situations, the outdoors air needs to be much less energised than the return air for the system to click here for more get in the economiser setting., and public buildings during construction, however because they call for a network of large air ducts throughout the structure they are very challenging to retrofit (mount in a building that was not developed to obtain it).
