COOLING CAPACITIES46 kW to 152 kW

YORK YCCD twin refrigerant circuit aircooled liquid chillers are a compact designsuitable for chilled water or glycol cooling.

YCCD units are available in threeversions: YCCD (standard); YCCD LN(low noise operation) and YCCD HT (hightemperature operation). YCCD models 60- 150 of all three versions are availablewith either user friendly standard control oroptional YORK Integrated SystemNetwork (ISN) control. YCCD models 170- 210 are fitted with YORK ISN control asstandard.

YCCD units are designed to be locatedoutside on the roof of a building or atground level. The units can be convertedinto total cooling plants with the fieldmounted Hydro Kit option.

YCCD LN (Low Noise Version)Very low noise levels are achieved on YCCD LN units without any impact on unitperformance or operating limits. The noise reduction is obtained using greatersurface area condenser coils and special fan configuration. In addition, on models60 - 150, the compressor compartment is completely acoustically insulated. Mufflersare mounted on the compressor discharge lines of all models and each compressoris also separately enclosed in an acoustic sound blanket.

YCCD HT (High Temperature Version)YCCD HT units are suitable for operation at higher ambient temperatures. Thehigher ambient limit is obtained using greater surface area condenser coils and highefficiency fans.

TABLE 2 OPERATING LIMITATIONS

SELECTION GUIDEDATA REQUIREDTo select a YORK YCCD chiller the following information isrequired:

1. Required cooling capacity.2. Design chilled liquid entering and leaving temperatures.3. Design chilled liquid flow rate.4. Design condenser entering air temperature. This will normally

be the design summer ambient air temperature unlesslocation or other factors have an influence.

5. Altitude above sea level.6. Design Cooler fouling factor.

Note: Items 1, 2 and 3 must be linked by the following formulae:

Cooling capacity (kW) = Flow Rate (l/h) x Range (°C)860

Where:Range = Entering chilled liquid temperature - leaving chilledliquid temperature.

YCCD SAMPLE SELECTIONA R407C chiller is required to cool water from 13°C to 7°Chaving a cooling capacity of 60 kW.

Other design conditions applying are:

Ambient air entering condenser: 35°CFouling factor: 0.044 m² °C/kWAltitude: Sea level

From a cursory examination of capacity Table 5 a model YCCD90 gives approximately the required capacity of 60.0 kW.

No correction factors, for fouling factor or altitude, applytherefore the conditions will be as follows:

Cooling capacity: 60.0 kWTotal unit input power: 26.3 kWWater temperature: 13 °C to 7 °CWater flow rate 60.0 = 2.38 l/s

4.187 x 6Cooler pressure drop = 16 kPa (see Figure 2).

Notes:

The optional strainer limits the unit maximum flow rate to10.4 litres per second.

The pressure drops given are for the strainer component only.They do not include the pressure drop of any other piping orfittings required to mount the strainer. The strainer is to beinstalled by others.

For glycol operation, the pressure drop correction factors foreither ethylene or propylene glycol solutions need to be appliedas shown in the pressure drop correction graphs.

REFRIGERANT FLOW DIAGRAM FIGURE 1

YCCD Cooling ModeLow 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 via the air cooled condenser coil and fans. The fully condensed and subcooled liquid refrigerant thenenters the expansion valve where pressure reduction and further cooling takes place before returning to the cooler.

GLYCOL SELECTION GUIDEDATA REQUIREDTo select a YORK YCCD glycol chiller, the following informationis required.

1. Required cooling capacity.

2. Design chilled liquid entering and leaving temperatures.

3. Design chilled liquid flow rate.

4. Design condenser entering air temperature. This will normallybe the design summer ambient air temperature unlesslocation or other factors have an influence.

5. Altitude above sea level.

6. Design cooler fouling factor.

7. Static pressure resistance against condenser entering andleaving airflow where ducts, louvres, attenuators, etc., areused, at full unit air flow.

Note: Items 1, 2 and 3 must be linked by the following formulae:

Cooling capacity (kW) = Range (°C) x Flow (l/s)Glycol Factor

Where:Range = Entering chilled liquid temperature - leaving chilledliquid temperature.

To determine Glycol Factor refer to Figure 3 for ethylene glycolor Figure 5 for propylene glycol. For the design leavingtemperature look up the recommended concentration of glycoland the Glycol Factor at this concentration. This is the minimumconcentration which should be used for the design leavingtemperature. If a higher concentration is desired the GlycolFactor can be determined from Figure 4 for the ethylene glycolor Figure 6 for propylene glycol.

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

which most closely matches the required capacity at thedesign conditions of leaving chilled liquid temperature andentering air temperature.

2. Apply the relevant correction factors for fouling factor andaltitude (Tables 3 and 4) and glycol concentration (Figures 3or 5), to the capacity and power values from the capacitytables. Ensure the corrected capacity is still sufficient forrequirements.

3. Using the corrected capacity of the selected chiller, adjust thedesign temperature range, or flow rate, to balance theformulae shown in “Data Required”.

4. Physical and electrical data can now be determined fromTables 12 and 13.

5. Always re-check that selections fall within the designlimitations specified (Table 2).

SAMPLE SELECTIONA chiller is required for cooling propylene glycol from 4°C to -1°Chaving a required duty of 48 kW.

The following design conditions apply:

Fouling Factor: 0.088m °C/kWAltitude: 1200mAmbient air: 30°CGlycol Strength: 27% w/w

For propylene glycol leaving at - 1°C the recommendedconcentration from Figure 5 is 27%. The specified strength istherefore suitable.

From ratings using an "Ethylene Glycol" temperature of "-2°C"leaving temperature (Propylene Glycol capacity = EthyleneGlycol capacity at 1°C lower temperature) at 30°C air aYCCD 105 gives 49,6 kW capacity and 20,4 kW power (table 9).

From the design fouling factor, corrections of Capacity x 0.987and power x 0.995 apply (Table 3).

From the design altitude, corrections of Capacity x 0.973 andpower x 1.020 apply (Table 4).

From the design glycol strength, corrections of Capacity x 1.040and power x 1.010 apply, (Interpolation from Table 9).

Applying these factors to the selection: YCCD 105

Capacity = 49.6 x 0.987 x 0.973 x 1.040 = 49.5 kW

Compressor Power = 20.4 x 0.995 x 1.020 x 1.010 = 20.9 kW

For the glycol concentration specified and a leaving chilled liquidtemperature of - 1°C, Figure 6 shows a Glycol Factor of 0.243.The flow rate can be determined, therefore, from the formulashown in "Data Required".

49.6 kW = (4 - (-1)) x Flow (l/s)0.243

Flow rate = 49.6 x 0.243 = 2.4 (l/s)5

This satisfies the Operating Limits.

Cooler pressure drop can be found by taking the value of waterpressure drop Figure 2, for a YCCD 105 and multiplying by thecorrection factor (Figure 8), for 27% strength and a meantemperature of 1.5°C,

i.e. (4 + (-1))/2°C:

12.5 kPa x 1.25 = 15.6 kPa

The following connections are required:

• One 400-3-50 Hz supply plus earth.• Control interlocks if required.

The power connections and interlocks can be made to a single terminal strip. Supply cables should enter the unit via a holeprovided.Mains isolator switches should be located adjacent to the unit and should incorporate provision for locking in the off position.Installation of differential safety cut-outs is recommended to prevent damage due to phase failure.
