ESGCompetitive & non-competitive ranges By: Ricky Choy ricky.choy@yorkna.com.hk
Product Map • YR • T0 and T1 available now. • 150 to 200 TR, same model, YRTBTBT0550A • 210 TO 230 TR, YRTCTCT1550A • 240 TR, YRTDTCT1550A • 250 TR, YRTDTBT1550A • Competitive at 200 TR, and all models with T1 compressor (10 % less than YS in average)
Product Map • YK • P1 & P2 (250 – 320 TR) • Prefer P2 for 89.6 F condenser water temp. • P3 & P4 (330 – 380 TR) • P5 (390 – 420 TR) • P6 (470 – 550 TR)
Product Map • From comparison of PA price, P3 to P6 YK chiller is almost the same as YT from 400 to 550 TR • Further cost study from Wuxi is required.
Note: Done • YK P5 & P6 (replacing G4 & H4) – May 2002 • YK P3 & P4 – May 2002 • YK J2 - J4 (1200-2000 TR) – as required • YS S7 (800-1000 TR) – under evaluation • YR (170-550 TR) – 2003 • Others:- • Performance Test up to 2000 RT – Dec 2001 • P Compressor manufacture and export – under evaluation
York Distinguish Features • Optiview Panel • Evaluation of energy saving utilizing low condenser water temperature • VSD • NPLV
Optiview Panel • Graphic displayed control center • Code free • Navigation bar quickly guides you to the level of information you need • Multi-languages • All information are shown in association with illustrations to the appropriate components.
Optiview Panel • On screen Trend Analysis – trending of up to six different parameters (Trane and Carrier requires BAS to achieve this function)
Utilizing low condenser water temperature Lowering energy cost with cold tower water
Utilizing low condenser water temperature • Lower condenser water temperature • Lowers head pressure • Reduce compressor work • Reduce energy consumption
Shift Specifications Before • Full-load kW/ton • 89.6°F entering condenser water Today • Part-load kW/ton (NPLV) • Condenser water relief • Off-design 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 55F condenser water temperature • Competitors limited to higher condenser water temperature (70- 75F)
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
VSD • York VSD is special design for chiller application • York VSD enters the market since 1979 as pioneer • Adaptive capacity control learns and remembers motor speed and PRV position for a given set of conditions, which fine tunes chiller performance • Carrier can provide it by Toshiba only with very high cost, and not for chiller application
VSD • Size • York • Unit mounted • Up to 503 HP, no increase in overall size of chiller • Up to 790 HP, 12” increase beyond tube sheet boundary for YT, and 14” for YK • Trane • Not available for 50 HZ
VSD • Size • Carrier • Remote installed inverter, additional floor space and service required • 100 – 200 HP, 42 x 30 x 90 inches (W x D x H) • 250 – 300 HP, 48x 30 x 90 inches (W x D x H) • 400 HP, 55 x 24 x 88 inches (W x D x H) • 500 – 700 HP, 71 x 24 x 88 inches (W x D x H)
VSD • IEEE 519- 1992 • Important for applications where other equipment may be affected by electrical noise (e.g. hospital, electronic factory) • York can provide an option to meet the harmonic distortion requirements of IEEE 519-1992 • Trane provide “Input line reactor filter” to HELP meet the IEEE specification
NPLV • The new IPLV/NPLV Formula is the most significant change to ARI 550/590-98 • New Term…NPLV • Non-standard Part Load Value • Replaces APLV • Old assumptions APLV were not realistic • Weightings were not distributed properly • Condenser temperatures did not reflect weather accurately
