The district cooling system is used to supply the St. Pölten State Clinic with cold water for air conditioning. The required base load is provided in summer by an absorber chiller, in winter by a free cooling station. The heat is dissipated via a heat exchanger that is charged from a water flow nearby. The turbo chillers are used to cover residual and peak loads. The individual transfer stations are supplied with cold air via an underground transmission line in Mühlweg and Matthias-Corvinusstraße. System data: absorber chiller with 2 MW cooling capacity, 4 turbo chillers with 2.5 MW cooling capacity each, 4 hybrid recoolers installed above the Mühlbach, 2 cold water storage tanks (1 x 750 m³ and 1 x 1000 m³).
