Utilizing low condenser water temperature Lowering energy cost with cold tower water
Utilizing low condenser water temperature ÞLowers head pressure ÞReduce compressor work ÞReduce energy consumption
Shift Specifications Before ¨ Full-load k. W/ton ¨ 89. 6°F entering condenser water Today · · · Part-load k. W/ton (NPLV) Condenser water relief Off-design full load
Less than 1% of chiller run hours are at full load
Condenser water temperatures depends on local weather conditions.
Utilizing low condenser water temperature ¨ Applications which utilize the low condenser water temperature: – Constant load with varies condenser water temperature (e. g. factory)
Utilizing low condenser water temperature ¨ York chillers designed for 55 F condenser water temperature ¨ Competitors limited to higher condenser water temperature (70 - 75 F)
Utilizing low condenser water temperature ¨ Competitor’s problem with low entering condenser water temperature – Inadequate refrigerant flow – Oil loss to refrigerant circuits
VSD ¨ General Features – 30% annual energy saving – Minimum 0. 95 power factor – Soft starting, 0% LRA, and hence longer motor life – Help to prevent surging at part load operation – 1 to 2 years payback
