6.12 Heat pump

The heat pump draws energy from the environment (brine, water or air) and delivers it
to the heating system at a higher temperature level. If the heat pump is equipped with a
process reversing valve, it can also be used for active cooling. Also, brine-to-water and
water-to-water heat pumps can be employed for passive cooling.
