(1)20TR Chiller Units 2 compressors 220vac/3ph/60hz R-22 and R-410A
20STB-25AD3 +加差价(5250-3690)*2=3120
SM147改为SM120(60HZ)
(2)50TR Chiller Units 2 compressors 220vac/3ph/60hz R-22 and R-410A
40STE-210AS3+差价(差价为0)
(1)RC2-260B压缩机改为两台并联压缩机SM350(S175+S175) (此压缩机买不到货)220vac/3ph/60hz,SM350改为RC2-200B
(2)SY300*2,220vac/3ph/60hz,电器多加5%,成本增加3000元;
(3)80TR Chiller Units 2 or 4 compressors 220vac/3ph/60hz & 440vac/3ph/60hz R-22 and R-410A
40STE-280AS3+0差价
压缩机由RC2-340B改为RC2-300B 220vac/3ph/60hz差价为0 如果压缩机改为两台并联压缩机SY482(S240+S240)两台,价格加28000元(利润多加一点)。
(4)100TR Chiller Units Your design 220vac/3ph/60hz & 440vac/3ph/60hz R-22 and R-410A
按照40STE-340AS3价格+压缩机差价为 原来压缩机:RC2-410B/50HZ
220V(440v)-60HZ: RC2-340B
(5)120TR Chiller Units Your design
440vac/3ph/60hz R-22 and R-410A
按照40STE-420AD3 +压缩机差价为0
原来压缩机:RC2-260B/50HZ
220V(440v)-60HZ:RC2-230B
220vac/3ph/60hz &
