Gorenje – Cooling

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
potential.

In summer months, the system struggled to meet Gorenje’s cooling
needsdue to a lack of capacity.

GGE SOLUTION

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.

RESULTS

0 %
Annual cost savings on cooling energy
  • More reliable with installed failsafes, the new system helps save power in winter.
