Systems with small storage spaces can be hybrid, making use of cost-free cooling at the beginning of the warmer period prior to switching to a warmth pump to further cool the circulation coming from the storage later in the period. These heatpump are added-in because the storage serves as a warm sink when the system remains in cooling (rather than charging) mode, triggering the temperature to slowly enhance throughout the air conditioning period.


In both cases, the outside air has to be much less energetic than the return air for the system to go into the economiser mode., and public structures during building, nevertheless because they require a network of big air ducts throughout the structure they are really challenging to retrofit (mount in a building that was not designed to obtain it).
