Using ice slurry as secondary refrigerant for charge reduction in industrial facilities

Abstract

This work analyses warming impact and electricity cost in farm milk cooling facilities when direct expansion systems are replaced by ice slurry based secondary refrigeration systems. The environmental improvement obtained has been assessed by comparing the TEWI values obtained using ice slurry with those obtained using a direct refrigeration facility. Economical effects have also been assessed by evaluating power consumption and taking into account the feasibility of benefiting from reduced electricity rate by producing and accumulating ice slurry during off-peak hours.
