ALTERNATIVE CHILLED FLUID APPLICATIONS -

Standard water chilling application range is 40°F to 50°F (4.4°C to 10°C) Leaving Chilled Water Temperature. To protect against nuisance safety trips below 40°F (4.4°C) and reduce the possibility of cooler damage due to freezing during chiller operation, the unit microprocessor automatically unloads the compressors at abnormally low suction temperature (pressure) conditions , prior to safety shutdown.

• Process Brine Option – Process or other applications requiring chilled fluid below 40°F (4.4°C) risk water freezing in the evaporator, typically overcome by using antifreeze. For these applications, the chiller system incorporates brine (ethylene or propylene glycol solu-tion), and the system design Leaving Chilled Fluid Temperature must be provided on the order form to ensure proper factory configuration.

• Thermal Storage Option – Thermal Storage requires special capabilities from a chiller, including the ability to ‘charge’ an ice storage tank, then possibly automatically reset for operation at elevated Leaving Chilled Fluid Temperatures as required by automatic building con-trols. The Thermal Storage Option provides Ice Storage duty Leaving Chilled Fluid setpoints from 25°F to 15°F ( -4°C to -10°C) minimum during charge cycle, with a Reset range of 36°F (20°C) supply fluid temperature.

Low-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 vapor enters the compressor where pressure and superheat are increased. High-pressure vapor is passed through the oil separator where heat is rejected to the con-denser 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 take place. The low pressure liquid refrigerant then returns to the cooler. Each refrigerant circuit utilizes liquid injection, maintaining efficient oil temperature operation within the compressor.

GUIDE TO SELECTION

Complete water chilling capacity ratings for YORK YCWS chillers are shown on the following pages to cover the majority of job requirements. For any application beyond the scope of this Engineering Guide, consult your nearest YORK Office.

SELECTION RULES

1. RATINGS - YCWS 200, 230 380, 460 & 575-3-60 rating are certified in accordance with ARI standard 550/590, at the ARI standard condition. Rating not at standard ARI conditions are rated in accordance with ARI rating procedures. These ratings may be interpolated but should not be extrapolated.

2. COOLING WATER QUANTITY - Ratings are based on 10ºF chilled water range. Use the chilled water correc-tion factors (below) for other ranges except as limited by water pressure drop, minimum or maximum water flows for the cooler.

3. CONDENSER WATER QUANTITY – Rating are ap-plicable from 2 to 4 gpm/ton as limited by water pres-sure drop or minimum or maximum water flows for the condenser. Using the tabulated MBH, the Cond. GPM is calculated as follows:

MBH x 2 Cond. Water Range (ºF)

4. FOULING FACTORS – Rating are based on 0.0001 evaporator and 0.00025 condenser fouling factor. For other fouling factors, consult the table below or contact your YORK representative.

METHOD OF SELECTION

If the duty requires a 10ºF range on both the cooler and condenser, see “Ratings”. For water ranges other than 10ºF, use the following procedure.

1. Determine capacity required from the following for-mula

GPM x Chilled Water Range (ºF) Capacity (tons) = 24

2. After applying any fouling factor corrections, the actual condenser heat rejection may be determined as fol-lows:

Heat Rejection (Btuh) = (Tons x 12,000) + (kW x 3415)

Heat Rejection (Btuh)Heat Rejection (MBH) =

= (Tons x 12) = (kW x 3.415)

3. Determine condensing water requirements for water cooled models as follows:

Heat Rejection (MBH) x 1000 Condenser Tons = 15,000

Condenser Tons x 30 Cond. Water GPM = Condenser Water Range (ºF)

Or combine the two formulas:

MBH x 2 Cond. Water GPM = Condenser Water Range (ºF)

15JOHNSON CONTROLS

SAMPLE SELECTION

Water Cooled Condenser (YCWS)

GIVEN – Chill 200 GPM of water from 56ºF to 44ºF and

0.0001 evaporator fouling factor with 85ºF to 95ºF con-densing water available. Fouling factor of 0.0005 special field for the condenser.

FIND – The required unit size capacity, kW, EER, and water pressure drop.

SOLUTION:

1. Chilled water range = 56ºF - 44ºF = 12ºF and correction factors are 1.0133 for Tons and 0.9993 for kW for the cooler.

GPM x Chilled Water Range2. Capacity (tons) =

= 200 x 12 = 100TR

2. From the rating, a model YCWL0120SB has a capacity range required. For the cooler leaving water tempera-ture of 44ºF and a condenser leaving water temperature of 95ºF, the unit capacity rating table indicates:

Tons = 106.2

KW = 96.7

EER = 13.2

Correcting for the 12ºF chilled water range and the 0.0005 condenser-fouling factor:

Tons = 106.2 x 1.0133 x 0.9961 = 107.2TR KW = 96.7 x 0.9993 x 1.0065 = 97.3

The unit is suitable.

3. Determine the average full load kW and EER at 95.0 Tons

95.0 X (97.3) = 86.2KW

107.2

Tons x 12 = 95.0 X 12 = 13.2 EER = Kw 86.2

4. Determine the cond. Heat rejection as follows:

Heat Rejection (MBH) = (Tons x 12) + (kW x 3.415) = (95.0 x 12) + (86.2 x 3.415) = 1140 + 294 = 1434

5. Determine GPM condensing water as follows:

GPM Condenser Water = MBH x 2
