These heatpump are added-in because the storage functions as a heat sink when the system is in cooling (as opposed to charging) mode, causing the temperature level to slowly increase throughout the air conditioning period.

In both situations, the outdoors air has to be less energetic than the return air for the system to enter the economiser mode., and public buildings throughout building, nevertheless since they call for a network of huge air ducts throughout the building they are very challenging to retrofit (set up in a structure that was not developed to obtain it).
