Equipments with little storage spaces can be hybrid, using totally free cooling at the begin of the warmer season prior to switching to a heat pump to more chill the circulation coming from the storage later on in the season. These heatpump are added-in since the storage acts as a warmth sink when the system is in cooling (as opposed to billing) setting, causing the temperature to gradually increase throughout the air conditioning period.


In both cases, the outside air needs to be less energised than the return air for the system to enter the economiser mode., and public buildings throughout building, nonetheless because they call for a network of huge air ducts throughout the structure they are very hard to retrofit (install in a structure that was not designed to receive it).
