Kylmätilojen kuljetinkäyttöjen energiatehokkuus

We study how conveyor drives in refrigerating rooms affect total energy costs. Studied conveyor drives are different types of gear motor drives. Energy efficiencies of the conveyor drives are determined by using direct torque measurement and energy costs of the conveyor drives are approximated from these results. From the measurement results and the approximated total costs it can be seen how the energy efficiency of a conveyor drive has a considerable influence on the total costs, especially, with large operating hours. An energy efficient conveyor drive can minimize the total energy costs by reducing the energy consumption of the conveyor motor while cooling costs in refrigerated rooms are also reduced.
