Piping connections
Oil free Centrifugal chiller provide different Cooling capacity, Power input, EER, etc (at fixed evaporator and condenser water conditions)
depending on the compressor speed of rotation;figures in the table are based on following standard conditions:evaporator 12/7°C; condenser
30/35°C. EER and ESEER reported in the table represent the maximum at these conditions and at a specific speed. A dedicated selection
tool (
WMC Selection Software
) is available to select the units and calculate the performance at specific working conditions
Low suction and high discharge pressure
Surge high motor temperature
Evaporator water inlet/outlet
Sound pressure related to maximum cooling capacity at standard conditions, according to ISO3744 at 1m and free field semi spherical
conditions
Low motor current
Starter fault
Sensor fault
Evaporator - Condenser water flow loss
Condenser water inlet/outlet
Nominal water flow rate (3)
Nominal Water pressure drop (3)
Type Flooded Shell&Tube (2 passes)
For dual compressor units the minimum capacity is related to the condition with only one compressor running
Nominal water flow rate and Pressure drop values are related to maximum cooling capacity at standard conditions; values at specific working
conditions can be calculated by the WMC selection software

Notes
Allowed voltage tolerance ± 10%. Voltage unbalance between phases must be within ± 3%.
Maximum current for wires sizing: compressors full load ampere x 1,1.
Maximum unit current for wires sizing is based on minimum allowed voltage
Maximum starting current: starting current of biggest compressor + current of the compressor at 75% maximum load
Nominal current in cooling mode is referred to the following conditions: evaporator 12/7°C; condenser 30/35°C
