(11) June: Cooling: Passive ‚natural‘ cooling.

(11) Heat Pump System LEO_2 June

(11) Cooling season starts: An automated 3-way valve diverts brine (that has been cooled by the water in the underground tank) through a heat exchanger in the buffer tank which had been used for space heating in the colder season. Heating loops now become cooling loops. The automated mixer makes sure that the cooling water temperauture (in the loops) does not drop below the dew point.
