3 Performance Rating Basis 1. CONDENSING UNIT RATINGS ARE AT THE FOLLOWING CONDITIONS Ambient temperature of 30, 35, 40, 43 or 46 C. Liquid entering temperature with inherent subcooling averaging 2 to 3 K. Return vapour temperature of 20 C. Return vapour temperature should never exceed 20 C for any refrigerant. Low temperature applications should be restricted to maximum 20K return vapour superheat. All capacity data based on continuous condenser fan operation without the consideration of fan speed control. 2. THE FOLLOWING FACTORS MAY BE USED WITH SUFFICIENT ACCURACY FOR CAPACITY CORRECTION AS REQUIRED For changed ambient temperature: interpolate as necessary. For changed liquid entering temperature: increase capacity 1% for each 1 C lower liquid temperature. Vice versa for each 1 C higher liquid temperature. For lower return vapour temperature: R22: Disregard - generally marginal. R404A: Use factors below for 10K return vapour superheat. SST R404A Multiply rated capacity by factor to get capacity at 10K superheat. 3. LIQUID RECEIVER CAPACITY Refrigerant factor for liquid receiver capacity R507: multiply R404A liquid receiver capacity by R407C: multiply R22 liquid receiver capacity by UNIT INPUT WATTS, MCC (MAXIMUM CONTINUOUS CURRENT) AND RLA (RATED LOAD AMPS) RLA and input watts values are given for the stated load condition based on calorimeter data where possible. Actual values may vary with varying conditions. RLA and input watts are intended as a guide for comparison purposes with other equipment. MCC is intended to be used as a guide for power supply rating, protection setting, and functional settings such as CPR valve. Unit RLA = Compressor RLA + Condenser Fan RLA. Unit MCC = Compressor MCC + Condenser Fan RLA. Unit Input Watts = Compressor Input Watts + Condenser Fan Input Watts. 5.

Sound Power - Tests were done with a sound intensity meter generally in accordance with the methods of ISO at approximately -10 C sst and +45 C sct compressor operating conditions. SOUND PRESSURE AT 3m USING 20.5dB DEDUCTION FROM SOUND POWER - That is at Location 1. Sound Pressure levels in other application environments at a 3 metre distance from the unit can be estimated using the various deductions below.

Sound pressure level, db(a). 6. REFRIGERANT CAPACITY OF CONDENSING UNITS Refrigerant capacity correction data is based on compressor capacity data from the manufacturer, and published thermodynamic data from the refrigerant manufacturers. Figures are an average of data for all models, and are given at 32 C ambient condition. Values can be used with sufficient accuracy over a wide range of ambient temperature without further correction. R507: multiply R404A capacity by 1.03 to find R507 capacity data. R507: application limits are the same as for R404A. R407C: the capacity and application limits are the same as for R22. 3

4 Performance Rating Basis 1. OIL TYPES USED IN KIRBY COMMANDER CONDENSING UNITS All compressors used in Kirby Commander condensing units are charged with PolyolEster (POE) oil. POE oil can be used with HCFC refrigerants, such as R22, and HFC refrigerants, such as R404A, R507, R407C and R134a. Use ONLY POE oil, do NOT mix POE with other oils, when using HFC refrigerants. Use RL32HTOil if the exact oil listed on the compressor is not available 2. RECOMMENDED HIGH/LOW PRESSURE SWITCH SETTING HIGH PRESSURE LIMIT SETTING Kirby Commander condensing units have a maximum operating pressure of 32 Bar(a) set by pressure vessels codes which apply to items such as the liquid receiver. Pressure limiting device can have a maximum setting of 29 Bar(a), = 0.9x32. Lower values are also acceptable in accordance with AS/NZS1677.2:1998. Kirby Commander condensing units have a maximum design condensing temperature of 58 C. When setting the HP control, consideration must be given to the type of refrigerant used and the maximum ambient temperature to ensure compliance with AS/ NZS and avoiding nuisance tripping. LOW PRESSURE SAFETY The cut-out points shall be 3-5 K below the minimum design evaporating temperature, the differential shall be no more than 2 Bar depending on the application and compressor. When the units are installed in a very cold ambient, the cut-out pressure shall be lower than the pressure corresponding to the ambient temperature. The cut-out pressure shall be in the positive pressure region. Do not operate compressors in deep vacuum conditions as this can cause electrical failure. Compressors should never be used to evacuate refrigeration or air conditioning systems. 3. REFER TO THE SECTION OF STANDARD & OPTIONAL CONFIGURATIONS FOR INFORMATION ON OPTIONS STANDARD CONFIGURATIONS Crankcase heater Oil separator, liquid receiver, liquid line dryer, sight glass, dual pressure control, motor protection and fan speed control for all units. All electrical controls are wired to terminal strip in electrical enclosure. Note: Fitting the suction accumulator option is recommended for the units in low temperature application. 4. FAN SPEED CONTROL RGE-Z1N4-5 (4A, 1Ph), RGE-Z1Q4-5 (8A, 1Ph) The controller varies the supply voltage to the fan motor from 45% to at least 95% over the proportional condensing pressure band which is factory fixed at 4 bar. The full voltage set point (FVS) is adjustable from 8-28bar, and is set by Heatcraft at 19 Bar for R404A medium temp. By turning the setting screw clockwise, the pressure setting increases. Turn anti-clockwise to decrease the pressure setting. The set point can be seen on the range setting pointer. The cut-off point is defined at 45% supply voltage to the fan motor, at factory setting this is 15±1 Bar depending on actual load and / or power supply. When the condensing pressure reduces to the minimum speed condition, the factory setting of Min Speed on the change-over switch ensures that the fans continue to run at this speed regardless of how low the pressure goes below the minimum. Alternatively, the change-over switch can be set in the field to Cut-Off, in which case the controller will cut power to the fans and the fans will stop. The fans will then restart at low speed when the pressure rises. For details, please refer to the manufacturers product specification. Heatcraft factory setpoint for primary refrigerant R404A is 19 Bar(g) for M/T & 14 Bar(g) for L/T units. Heatcraft Australia recommends 16 Bar(g) for R22, 10 Bar(g) for R134a units. 4

5 Performance Rating Basis 5. CAPACITY CONTROL FOR DORIN H34 & H4 SERIES COMPRESSORS Dorin H34 & H4 compressors are 4 cylinders with 2 discharge heads. When capacity control is in operation, one discharge head is disabled by blocking the suction gas from entering the cylinders. Due to less refrigerant flow, thus less cooling effect to the electric motor, the running discharge head becomes hotter and the inactive head continually has reciprocating mechanical motion, thus been heating up over time. Hence it is recommended to have the following protection features implemented during capacity control operation. Fit a head cooling fan to reduce the temperature of compressor heads. Limit compressor operating range. Limit compressor continuous operating time to 2-3 hours. Then a 3-5 minutes operation at full capacity is necessary to cool the compressor down before the next capacity control operation. 5
