Systems with little storage spaces can be hybrid, making use of free cooling at the begin of the warmer season prior to switching over to a more info heatpump to additional cool the blood circulation coming from the storage space later in the period. These warm pumps are added-in since the storage acts as a warm sink when the system is in air conditioning (rather than charging) mode, creating the temperature level to slowly enhance during the air conditioning season.
return air or compare the enthalpy of the air, which is commonly done in high humidity environments and it triggers more of an issue. In both cases, the outside air should be much less energetic than the return air for the system to go into the economiser setting.
