SITUATION BEFORE THE CONTRACT AND CLIENT REQUIREMENTS
Gorenje’s plant in Velenje requires a cooling system with a capacity of
1600 kW, to cool hydraulic oil and tools.
Its original two cooling systems had an insufficient cooling capacity, were
obsolete and had a low energy efficiency ratio, in addition to which they
operated all year long and did not take advantage of the free-cooling
In summer months, the system struggled to meet Gorenje’s cooling
needsdue to a lack of capacity.
Two-temperature cooling regime: one mode to cool hydraulic oil with
temperatures of 30/35° C and a capacity of 940 kW, and a second mode
to cool tools with temperatures of 15/20°C and a capacity of 660 kW.
The system is sized based on the quantities of plastic materials actually
processed(cooling requirement of 250 W / kg of input material).
The system maximizes the possibility of using free-cooling, uses adiabatic
cooling via an autonomous demi water system that allows the system to
operate during very high temperatures.
Annual cost savings on cooling energy
More reliable with installed failsafes, the new system helps save power in winter.
