Low pressure liquid refrigerant enters the cooler and is evaporated and superheated by the heat energy absorbed from the chilledliquid passing through the cooler shell. Low pressure vapour enters the compressor where pressure and superheat are increased.The high pressure vapour is fed to the air cooled condenser coil and fans where the heat is removed. The fully condensed andsubcooled liquid passes through the expansion valve where pressure is reduced and further cooling takes place before returning tothe cooler.

SELECTION GUIDE - WATERDATA REQUIREDTo select a YORK YLAE water chiller, the following informationis required:

1. Required cooling capacity.2. Design chilled liquid entering and leaving temperatures.3. Design chilled liquid flow rate if one of the temperatures in

item 2 are unknown.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.

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

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

Cooling capacity kW = l/s chilled liquid x range (°C)0.2392

Where:Range (°C) = Entering liquid temperature - Leaving liquidtemperature.

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

which most closely matches the required capacity at thedesign conditions of leaving water temperature and enteringair temperature (Table 6).

2. Apply the relevant correction factors (Tables 3 and 4) to thecapacity and power values from the capacity table (Table 6).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 7 and 8.

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

YLAE SAMPLE SELECTION - WATER COOLINGA R410A chiller is required to cool water from 12°C to 7°Chaving a cooling capacity of 220 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 6 a YLAE0235SEgives approximately the required capacity of 222.2 kW

Since no correction factors for fouling or altitude apply, theconditions will be as follows:

Cooling capacity: 222.2 kWCompressor power: 78.8 kWWater temperature: 12 °C to 7 °CWater flow rate 222.2 x 0.2392 = 10.6 l/s

5Cooler pressure drop = 43.7 kPa (see Figure 3).

Note: When selecting chillers with optional dual speed fans, atambients below 30°C the Low Sound Unit capacity tables shouldbe used to obtain unit capacity and power. At ambients above30°C the Standard Unit capacity tables should be used to obtainunit capacity and compressor power.

(1) Liquid sub-cooling measured at the liquid line should be between 8.5 and 11.0 °C at circuit full load.(1) Sub-cooling is determined by the level of refrigerant charge in each system.(2) The unit capacity control percentages stated in brackets, apply when the largest compressors(2) on the lead and lag systems are stating first.(3) Sound Pressure levels are 1 m from the Control Panel, at a height of 1.6 m from the unit base.(2) Levels may vary at different positions around the unit. Levels do not include Hydro Kit Option.

SPACE REQUIREMENTS

The recommended clearances and dimensions are the distances between the edge of the units and the architectural enclosuresurrounding them. It is important that adequate space is available to ensure that air discharged via the fans is not recirculated intothe condenser coil intake, which would reduce the unit capacity.

The dimensions at the front and rear of the units allow for access to the control panel and for component removal.

The enclosure height should not exceed the height of the units. Horizontal obstructions or overhangs should not be closer than 15metres above the top of any unit and no obstructions are allowed directly above the unit.
