YCSE/YCREWATER ANDREMOTE AIRCOOLED LIQUIDCHILLERR407C REFRIGERANT

COOLING CAPACITIES126 kW to 316 kW

YORK YCSE Water Cooled Liquid Chillersare a compact design suitable for chilledwater or glycol cooling. YCRE models arefor applications where remote condensersare necessary.

They are designed to be located inside aplant room and require a cooling tower ordry cooler for heat rejection.

Units are available with one or twoindependent refrigerant circuits with asingle evaporator and on YCSE models asingle condenser.

The units utilise advanced electroniccontrol to position the variable capacitycontrol slide valve within eachcompressor. This ensures exact loadcontrol, accurate chilled watertemperature control and improved partload performance.

Cooling Mode - YCSELow pressure liquid refrigerant enters the cooler (Evaporator) and is evaporated and superheated by the heat energy absorbed fromthe chilled water passing through the cooler plates. Low pressure vapour enters the compressor where pressure and superheat areincreased. Heat is rejected by the water cooled condenser. The fully condensed and subcooled liquid refrigerant then enters theexpansion valve where pressure reduction and further cooling takes place before returning to the cooler.

SELECTION GUIDEDATA REQUIREDTo select a YORK YCSE/YCRE chiller the following informationis required:

1. Design cooling capacity.

2. Chilled water entering and leaving temperatures.

3. Condenser water entering and leaving temperature.

4. Chilled water flow (L/s) if one of the temperatures in (2) isunknown.

5. Condenser water flow (L/s) if one of the temperatures in (3) isunknown.

Determine the capacity or water flow from:

Cooling Capacity (kW)= Range (°C) x chilled water flow rate (L/s) x 4.18

Determine the heat rejection or water flow from:

Heat Rejection (kW)= Range (°C) x condenser water flow rate (L/s) x 4.18

CHILLER SELECTION METHOD1. Determine the correct size of chiller by selecting the model

that most closely matches the required capacity at the designconditions of leaving water temperature and condenserleaving water temperature.

2. Apply correction factors for fouling factor to the capacity andpower values from the capacity tables. Ensure the correctedcapacity is still sufficient for requirements.

3. Using the corrected capacity of the selected chiller adjust thedesign temperature range, or flow rate, to balance theformulae shown above.

4. Physical and electrical data can now be determined from thetables.

5. Always re-check that selections fall within the operatinglimitations.

2. Select Model and Read the Performance

From the capacity table, modelYCSE080SB can be selectedwith the following performance.

Cooling Capacity: 247.7 kWCompressor Input Power: 66.9 kWHeat Rejection 314.6 kW.

3. Determine the Flow Rate

Cooling Capacity (kW)= Range (°C) x chilled water flow rate (L/s) x 4.18Flow Rate = 247.7 = 11.8 L/s

5 x 4.18Heat Rejection (kW)= Range (°C) x chilled water flow rate (L/s) x 4.18Flow Rate = 314.6 = 15.1 L/s

5 x 4.18

4. Correct the Data

Fouling Factor

The cooling capacity and the compressor input should becorrected using the factors given below, if applicable.Recalculate flow rates as required.

Flow Rate

When 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 RateTemp. Difference(°C)

The corrected Flow Rate must be confirmed to be within theworking range.

Glycol Application

On applications with leaving chilled temperatures below 5°C theGlycol Application Factors given below should be applied.

5. Determine the Pressure Drops

Calculate the pressure drops using the graphs or formulae givenbelow.

Evaporator pressure drop at a flow rate of 11.8 L/s would be 46.3kPa.

Condenser pressure drop at a flow rate of 15.1 L/s would be 65.5kPa.

6. Check the Data is within Limits

The data is within the unit operating limitations.

TABLE 12 ACOUSTIC DATA

TABLE 13 ELECTRICAL DATAThe following connections are required:

• One 400 V, 3 phase, 50 Hz supply plus neutral and earth.• Control interlocks if required.

The power connections are made to the unit screw terminals inthe control panel. Interlocks are made to a terminals in thecontrol panel.

Supply cables should enter the unit via the holes provided in thepanel.

A customer supplied mains isolator switches should be locatedadjacent to the unit and should incorporate provision for lockingin the off position.

I.P. = Input Power; NRA = Nominal Running Current; LRA = Starting Current; MRA = Maximum Running Currrent;SMRA = Maximum Running Currrent during Starting.Compressor I.P. and NRA based on chilled water inlet/outlet temperature of 12/7°C and condenser water .inlet/outlet temperature of 30/35°CMRA is the maximum total unit running current at a supply voltage of 90% of the rated voltage with unit capacity of100% at maximum operating conditions. The power supply cables must be sized to cover this maximum current value.LRA is the first compressor starting current. SMRA is MRA and starting current, when other compressor starts.
