1.10 Cooling circuit
The cooling circuit is of the heat pump type with a refrigerant gas reversal cycle. The source fluid utilised is the outdoor air, while the utility-side fluid is
the air inside the rooms.
During the wintertime, the heat pump extracts the thermal energy from the outdoor air and delivers it to the room air, thereby heating it. During the
summertime the cycle is reversed, and the thermal energy is extracted from the room air, which is cooled, and is delivered to the outdoor air.
