Features

York YLCs water Cooled screw Chillers are a compact design suitable for water or water-glycol cooling. models are available in three versions:

• standard units (sa),

• units for applications requiring high condensing temperatures (Ha)

• units for applications where remote condensers are necessary (aa).

semi-hermetic twin helical screw compressors are provided to ensure high operational efficiencies and reliable performance.

they are designed to be located in a plant room and require a cooling tower or dry cooler for heat rejection.

unit to have final overspray paint after assembly (optional) by customer request.

Compressorseach compressor shall be direct drive, semi-hermetic, rotary twin screw type and include the following items:

• two screw rotors, with asymmetric profiles, manufactured from forged steel.

• a cast iron compressor housing precision machined to provide optimal clearance for the rotors.

• the entire compressor, from suction to discharge shall have a design working pressure of �1 barg.

• Capacity Control: the compressors shall start at the minimum load position and provide a load control range from 100% to 15% of the full load using step control. a microprocessor controlled output pressure regulating capacity control valve shall be supplied to command compressor capacity independent of control valve input pressure and to balance the compressor capacity with the cooling load.

• an automatic spring return of capacity control valve to the minimum load position to ensure compressor starting at minimum motor load.

• an internal discharge check valve to prevent rotor backspin upon shutdown.

• Remote acoustic tuned muffler.• discharge and optional suction shut-off service

YLCS SA & HALow pressure liquid refrigerant enters the cooler tubes and is evaporated and superheated by the heat energy absorbed from the chilled liquid passing through the cooler shell. Low pressure vapour enters the compressor where pressure and superheat are increased. High pressure vapour is passed through the oil separator in the compressor where compressor oil is removed and reticulated to the compressor. High pressure superheated refrigerant enters the condenser shell where heat is rejected to the condenser water passing through the tubes. the fully condensed and subcooled liquid leaves the condenser and enters the expansion valve, where pressure reduction and further cooling takes place. the low pressure liquid refrigerant then returns to the cooler.

1. design cooling capacity.2. Chilled water entering and leaving temperatures.�. Condenser water entering and leaving temperature.4. Chilled water flow (l/s) if one of the temperatures in

(2) is unknown.5. Condenser water flow (l/s) if one of the temperatures

in (�) is unknown.

Determine the capacity or water flow from:

Cooling Capacity (kw) = Range (°C) x chilled water (l/s) x 4.18

Determine the heat rejection or water flow from:

Heat Rejection (kw) = Range (°C) x condenser water (l/s) x 4.18

NOTE: if condenser coolant is glycol solution allow 2K increase in condensing temperature to estimate the cooling capacity & power impact on your selection.

Chiller Selection Method1. determine the correct size of chiller by selecting

the model which most closely matches the required capacity at the design conditions of leaving water temperature and condenser leaving water temperature.

2. apply correction factors for fouling factor to the capacity and power values from the capacity tables. Ensure the corrected capacity is still sufficient for requirements.

�. using the corrected capacity of the selected chiller adjust the design temperature range, or flow rate, to balance the formulae shown above.

4. Physical and electrical data can now be determined from the tables.

5. always re-check that selections fall within the operating limitations.

YLCS Sample Selection1. Confirm the system requirements Cooling Capacity: 400 kw Chilled water inlet temperature: 12 °C Chilled water outlet temperature: 7 °C Condenser water inlet temperature: �0 °C Condenser water outlet temperature: �5 °C evaporator and Condenser Fouling Factors: 0

2. Select Model and Read the Performance From the capacity table, model YLCs0415sa can be

selected with the following performance. Cooling Capacity: 41� kw Compressor input Power: 95 kw Heat Rejection 50� kw.

3. Determine the Flow RateCooling Capacity(kw) = Range(°C) x chilled water(l/s) x 4.18

=41�

= 19.76 l/s5 x 4.18

Heat Rejection(kw) = Range(°C) x condenser water(l/s) x 4.18

=50�

= 24.07 l/s*5 x 4.18

* Total unit flow rate.

4. Correct the DataFouling Factorthe cooling capacity and the compressor input should be corrected using the factors given below, if applicable. Recalculate flow rates as required.

Flow Ratewhen the water inlet/outlet temperature difference is not 5°C, correct the flow rate by the following formula:

Corrected Flow Rate =5 (°C) X Flow Rate

temp. difference(°C)

The corrected Flow Rate must be confirmed to be within the working range.

5. Determine the Pressure DropsCalculate the pressure drops using the graphs.

Evaporator pressure drop at a flow rate of 19.76 l/s would be 26 kPa.

Condenser pressure drop at a flow rate of 24.07 l/s would be �4 kPa.

6. Check the Data is within Limitsthe data is within the unit operating limitations.
