Number: pap. n. 14

Author(s) : BOONE J.

Summary

This paper presents the results of operation of Chillers with natural refrigerants in Switzerland. PLANT 1 - NH3-chiller is designed to produce 367 kW chilled ethylene glycol/water at -2/-6°C with an evaporating temperature of -9°C. The plant started in the fruit-season 2012 and operated approx. 3716 hrs at an overall COP of 4 to 5. PLANT 2 uses 2 piston compressors to produce 500 kW chilled water at 6°C and 350 kW glycol-water at -3°C in a coldstore by using NH3 direct expansion type chillers. The plant was started in 2010 and operated approx. 18000 hrs at an overall COP of 3~4.5. PLANT 3 - NH3 chillers use piston compressors to produce 250 kW cooling in a fruit cold storage plant with ethylene glycol at -7°C by using combined plate in shell evaporators. The plant started in 2011 and operated approx. 16000 hrs at an overall COP of 2.9.
