Systems with little storage spaces can be hybrid, utilizing totally free air conditioning at the start of the warmer period before switching to a warmth pump to additional chill the circulation coming from the storage space later on in the season. These heatpump are added-in due to the fact that the storage works as a heat sink when the system is in cooling (rather than charging) setting, causing the temperature level to slowly boost during the air conditioning season.


In both situations, the outside air should be much less energised than the return air for the system to get in the economiser mode., and public structures during building and construction, however due to the fact that they call for a network of large air ducts throughout the structure they are extremely difficult to retrofit (install in a building that was not made to obtain it).
