The system contains coolant and load circuits. The coolant circuit contains a compressor, condenser (8), vaporiser (6) associated tube connections and regulators and the load circuit contains the coolant flow via the condenser and connections for the load. The system also contains heat exchangers as additional coolers. At least two additional coolers (1,2) are switched on depending on ambient conditions, e.g. during the transition from summer to winter operation. One cooler is connected to the load side to precool the coolant and the other to the condenser of the cooling system for recooling within the cooling system.
