DESCRIPTION The RXF Rotary Screw Compressor Unit line consists of eleven models ranging in capacity from 71.5 cfm (122 m³/h) through 596 cfm (1013 m³/h). Standard units are designed for use on ammonia, halocarbon and hydrocarbon refrigerants for high-stage and booster service. Standard units consist of the following major components: Frick manufactured XJF Rotary Screw Compressor with “VOLUMIZER® II” variable volume ratio control and integral suction strainer; motor base; mounted “C” face or “D” flange motor and drive coupling; QUANTUM™LX control panel; suction seal cap or handwheel stop valve (separately shipped) and check valve; serviceable discharge seal cap stop and check valves; and a three-stage horizontal oil separator/reservoir. All components have been selected for maximum reliability and arranged to ensure accessibility for service. The units are factory packaged, complete with wiring and piping.

MODEL XJF COMPRESSOR The XJF compressor incorporates the latest available technology to bring large screw compressor reliability and efficiency to small screw compressor sizes. HOUSING: All screw compressor castings are designed and tested to meet the requirements of ASHRAE 15 safety code for 362 PSIA maximum working pressure. Castings are close-grain, ASTM-A 48 Class 40 cast iron to ensure structural integrity and mechanical and thermal stability under all operating conditions. ROTORS: The rotors are machined from AISI-1141 lowcarbon steel to the exacting tolerances of the latest SRM asymmetric profile. The five-lobed male rotor is directly connected to the gear drive. The seven-lobed female rotor is driven by the male rotor on a thin oil film. BEARINGS: Antifriction bearings, with an L10 rated bearing life in excess of 100,000 hours at design conditions, are used for reduced frictional horsepower and superior rotor positioning. This results in reduced power consumption, particularly at higher pressure ratios. Cylindrical roller bearings are provided to handle the radial loads and the thrust loads are absorbed by angular-contact ball bearings. In addition, thrust balance pistons are provided to reduce the thrust load and improve bearing life. SHAFT SEAL: The compressor shaft seal is a single-face type with a spring-loaded, carbon stationary surface and a cast iron rotating seat. The seal is capable of sealing up to 362 PSIA, but is vented to low pressure to provide extended seal life.

E70-400 SED (MAY 2006) Page 3

“VOLUMIZER® II” VARIABLE VOLUME RATIO CONTROL: The XJF compressor incorporates a simple automatic mechanism which adjusts the compressor volume ratio during operation to the most efficient of three possible volume ratios (2.2, 3.5 or 5.0), depending on system requirements. This minimizes the power penalty associated with over or undercompression and reduces excess bearing loading caused by running the machine at a less efficient Vi. The volume ratio control is achieved by the use of a slide stop which is a movable portion of the rotor housing that moves axially with the rotors to control discharge port location. The slide stop is moved by hydraulic actuation of a control piston. Slide stop position is controlled by signals from the microprocessor or manually. CAPACITY CONTROL: Capacity control is achieved by use of a slide valve. The slide valve moves axially with the rotors to provide infinite capacity adjustment from 100% to 25% of full load. The slide valve is positioned automatically by hydraulic movement of its control piston which receives signals from the microprocessor. When in the unloaded position, gas is bypassed back to suction through a recirculation slot before compression begins and any work is expended, providing the most efficient unloading method available for part-load operation of a screw compressor.

LUBRICATION SYSTEM LUBRICATION SYSTEM: The RXF compressor is designed specifically for operation without an oil pump for normal highstage operation. All oil required for main oil injection and lubrication is provided by positive gas differential pressure. OIL SEPARATOR/RESERVOIR: The oil separator is a horizontal, three-stage design with integral sump. Two sight glasses are located in the reservoir section and one in the coalescing section. The separator is designed and constructed in accordance with ASME Section VIII, Div. 1 for a maximum design working pressure of 300 PSIG and supplied with a relief valve. 500 watt heaters maintain oil temperature during shutdown and are replaceable without pumping the compressor down. A coalescent separator element is provided for final gas/oil separation of particles down to less than 1 micron. Oil is drained from the coalescer section and returned to the compressor suction during operation. An electronic sensor is installed in the reservoir section of the oil separator to detect a low oil level. If a low level occurs, the sensor will signal the control panel to shut down the compressor. OIL FILTERS: All oil passes through our new Frick SuperFilter™II. SuperFilter™ll captures 99% of particles 5 microns and larger and has twice the dirt holding capacity of the original SuperFilter™. It is also designed for horizontal mounting and furnished with isolation stop valves and drain connections for ease of servicing. Efficient oil management leads to longer bearing life.

RXF ROTARY SCREW COMPRESSOR UNITS SPECIFICATIONS

OIL COOLING EZ-COOL™ LIQUID INJECTION OIL COOLING: The compressor oil is cooled by direct contact with the refrigerant injected through one of two optimized port locations prior to the compressor discharge. Liquid feed arrangements include isolation valves, strainer, solenoid valve, sight glass, and a motorized thermal expansion temperature control valve. The temperature control valve will maintain the temperature of the oil returning to the compressor between 130° and 150°F.

Multiple Capacity Controllers provide application flexibility for auto setback control and control reset for changes in modes of operation. Override Controls for all safety and controller functions can be programmed to unload the compressor within maximum safety and control parameters. On-screen Calibrations for sensors, motor current, slide valve and slide stop have easy-to-understand graphics. Potentiometer tuning has been eliminated. Display backlight flashes on shutdown to attract attention in noisy engine rooms.

EXTERNAL OIL COOLING: The oil cooler can be either a flat plate (12–50) or plate and shell (58–101) design, depending on the application. The oil cooler is mounted on the unit with the oil piping connected. Refrigerant connections, controls, and safety valve must be field installed and supplied by others.

Selected data and selected time periods can be viewed in either an x-y trending chart or a tabular chart.

COMPRESSOR DRIVER The following information is required for proper coordination of the screw compressor unit and the compressor driver: Motor Specifications____________ HP Motor Power______ Volts, 3 Phase_____Hz (60 or 50 Hz) Motor Starting Method_______________ Across-the-line, Wye-delta, Transformer, Other - Consult Frick® *Motor Rotation _________________________________ * NOTE: Compressor rotation is clockwise when facing end of compressor shaft. MOTOR ROTATION MUST BE COUNTERCLOCKWISE WHEN FACING END OF MOTOR SHAFT.

The following information must be specified for each application:

STARTING METHOD Choose Solid-State, Across-the-line, Wye-delta Open Transition, Wye-delta Closed Transition, or Autotransformer. SOLID-STATE STARTING: Reduces power consumption during start-up. The in-line starter uses a traditional connection configuration that is easily understood by electricians. Our newest starter is positioned directly beneath the motor on the compressor package to reduce overall length and ensure a clean look for your engine room. ACROSS-THE-LINE STARTING: Yields full motor starting torque. However, power companies and/or in-house power distribution systems often require other starting methods to achieve reduced starting inrush current. NOTE: Reducing the inrush current also reduces the starting torque. A careful analysis of compressor torque requirements versus the available motor starting torque must be made. This can be accomplished by plotting the motor speed/torque curve (obtained from motor vendor) against the compressor speed/torque curve. The available motor torque should exceed the compressor torque requirement by a minimum of 20% at the worst portion of the curve. This usually occurs at approximately halfspeed in the region known as the motor pull-up torque (P.U.T.). When plotting these curves please remember that for starting methods other than across-the-line, the motor torque values are reduced as indicated. WYE-DELTA (CLOSED TRANSITION): Starting torque available is 33% of normal. While Wye-delta open transition starters exhibit the same torque characteristics as Wyedelta closed transition starters, closed transition is the more preferred method. AUTOTRANSFORMER: The Autotransformer starter has three voltage taps: 50%, 65% and 80%. The starter, unless specified otherwise, is normally shipped connected to the 65% voltage tap. This can be changed in the field as required. The starting torque available is: 80% Tap - 64% of normal torque 65% Tap - 42% of normal torque 50% Tap - 25% of normal torque OVERCURRENT PROTECTION: Choose either the Starter package or the Combination starter package with circuit breaker disconnect.

RXF ROTARY SCREW COMPRESSOR UNITS ENGINEERING DATA

STANDARD CONDITIONS - HIGH STAGE The RXF high-stage ratings for R-717 and R-22 are based on 10°F liquid subcooling (except no external liquid subcooling in economizer ratings), 10°F suction superheat (not contributing to the refrigeration effect), and thermosyphon or water-cooled oil cooling.

SELECTION PROCEDURE - HIGH STAGE The final rating for a RXF unit at any condition is determined from the standard rating and all of the applicable correction factors. Capacity (TR) = standard rating (or economized rating) x subcooling correction factor x superheat correction factor x liquid injection correction factor if applicable (see Liquid Injection Oil Cooling) x 0.83 (50 Hz only). Brake Horsepower (BHP) = standard rating (or economized rating) x 1.01 (liquid injection correction factor if applicable) x 0.83 (50 Hz only).

LIQUID SUBCOOLING CORRECTION FACTORS For liquid subcooling other than 10°F, determine the liquid subcooling capacity correction factor (S.C.C.F.) in the following manner using the actual number of degrees of liquid subcooling (S.C.): For R-717: S.C.C.F. = 1 + (S.C. - 10°F) (.0025) For R-22: S.C.C.F. = 1 + (S.C. - 10°F) (.005) No brake horsepower correction is required for liquid subcooling.

SUCTION SUPERHEAT CORRECTION FACTORS HIGH STAGE For suction superheat in excess of 10°F, determine the suction superheat capacity correction factor (S.H.C.F.) in the following manner using the actual number of degrees of suction superheat (S.H.): 1 For R-717: S.H.C.F. =

1 + (S.H. - 10°F) (.0027)

1 For R-22:

S.H.C.F. =

1 + (S.H. - 10°F) (.0028)

It is recommended that a minimum of 10°F of suction superheat be maintained to ensure that all refrigerant entering the compressor is in the vapor state. No brake horsepower correction is required for suction superheat.

LIQUID INJECTION OIL COOLING High-stage compressor units may be supplied with single-port (low Vi) or dual-port (low and high Vi) liquid injection oil cooling. Single port will be furnished for low-compression-ratio operation and dual-port for high-compression-ratio operation. Booster compressor units use single-port, liquid injection oil cooling due to the typically lower compression ratios. The control system with dual-port liquid injection oil cooling automatically switches the liquid refrigerant supply to the high port when the compressor is operating at high compression ratio (at 5.0 Vi) for best efficiency. The following table gives the condensing temperature(s) with the corresponding maximum evaporator temperature for liquid injection use and the minimum evaporator temperature for single-port application.

*Dual Injection Kit will be shipped by Frick below these temperatures. It is IMPERATIVE that an uninterrupted supply of high pressure liquid refrigerant be provided to the injection system at all times. Two items are of extreme importance: the design of the receiver/liquid injection supply and the size of the liquid line. It is recommended that the receiver be oversized sufficiently to retain a 5 minute supply of refrigerant for oil cooling. The evaporative supply must be secondary to this consideration. The dual dip tube method, which uses two dip tubes in the receiver, is the recommended method of accomplishing this. As shown in Figure 1, the liquid injection tube is below the evaporator tube to ensure continued oil cooling when the receiver level is low.

THERMOSYPHON OIL COOLING Thermosyphon oil coolers, like water-(or glycol-)cooled oil coolers, eliminate the capacity and power penalities associated with liquid injection oil cooling. Thermosyphon oil coolers have the further advantages of eliminating water (or glycol) pump power consumption and maintenance, tube fouling and potential system contamination. The principle of operation is as follows (see Figure 2). A supply of high pressure liquid is maintained in a receiver at a predetermined minimum head above the oil cooler and below the condenser. Gravity causes the liquid refrigerant to flow to the oil cooler where a portion of the liquid is boiled off, thereby cooling the hot oil. New liquid from the receiver displaces the lighter refrigerant liquid/vapor mixture which rises to the receiver, dropping out the remaining liquid before allowing the vapor to return to the condenser, completing the cycle.

E70-400 SED (MAY 2006) Page 75

PIPING ARRANGEMENT FOR THERMOSYPHON OIL COOLING SYSTEMS The components and piping of a thermosyphon oil cooling system include a liquid source at condensing pressure, adequate static heads to provide fluid flow, appropriate control valves, safety relief valves, service valves, and pump out connections. The arrangement of component placement and fluid flow requirements must be designed to suit the individual refrigeration system layout with consideration given to piping safety practices. The component and piping arrangement shown in Figure 2 is intended ONLY to illustrate the operating principles of thermosyphon oil cooling. Other component layouts may be better suited to a specific installation.

Figure 2 1. Thermosyphon oil cooler is supplied with the oil side piped to the compressor unit and stub ends supplied on the refrigerant side. 2. Three-way oil temperature control valve required where condensing temperature is expected to go below 65°F. 3. A refrigerant-side safety valve is required in this location only when refrigerant isolation valves are installed between the cooler and thermosyphon receiver. If no valves are used between the cooler and TSOC receiver, the safety valve on the TSOC receiver must be sized to handle the volume of both vessels. Then, the safety valve on the cooler vent (liquid refrigerant side can be eliminated. 4. System receiver must be mounted below thermosyphon receiver level in this arrangement.

RXF ROTARY SCREW COMPRESSOR UNITS ENGINEERING DATA

ECONOMIZER - HIGH STAGE (OPTIONAL) Compressor ratings with the economizer effect included are given in the ratings tables with the “E” suffix. No allowance for vapor line pressure drop has been included. Size the economizer vapor line (including valves, strainer, etc.) from the economizer vessel to the compressor for pressure drop from one to two PSI. The economizer rating tables are based on the application of a Flash Economizer System as shown in Figure 5 below. For capacity and brake HP with shell and coil or direct expansion (DX) type economizer (Figure 4), refer to page 89. The economizer option provides an increase in system capacity and efficiency by subcooling liquid from the condenser through a heat exchanger or flash tank before it goes to the evaporator. The subcooling is provided by flashing liquid in the economizer cooler to an intermediate pressure level. The intermediate pressure is provided by a port located part way down the compression process on the screw compressor. As the screw compressor unloads, the economizer port will drop in pressure level, eventually being fully open to suction. If this control is required, specify the optional RXF Plus microprocessor. It provides an additional output to turn off the supply of flashing liquid when the capacity falls below approximately 45%-60% (85%-90% slide valve position). This is done because the compressor will be more efficient operating at a higher slide valve position with the economizer turned off, than it will at a low slide valve position with the economizer turned on. Please note however that shell and coil and DX economizers can be used at low compressor capacities in cases where efficiency is not as important as ensuring that the liquid supply is subcooled. In such cases, the economizer liquid solenoid can be left open whenever the compressor is running.

E70-400 SED (MAY 2006) Page 87

Due to the tendency of the port pressure to fall with decreasing compressor capacity, a back-pressure regulator valve (BPR) is generally required on a flash economizer system (Figure 5) in order to maintain some preset pressure difference between the subcooled liquid in the flash vessel and the evaporators. If the back-pressure regulator valve is not used on a flash economizer, it is possible that no pressure difference will exist to drive liquid from the flash vessel to the evaporators, since the flash vessel will be at suction pressure. In cases where wide swings in pressure are anticipated in the flash economizer vessel, it may be necessary to add an outlet pressure regulator to the flash vessel outlet to avoid overpressurizing the economizer port, which could result in motor overload. Example: A system feeding liquid to the flash vessel in batches. The recommended economizer systems are shown below. Notice that in all systems there should be a strainer and a check valve between the economizer vessel and the economizer port on the compressor. The strainer prevents dirt from passing into the compressor and the check valve prevents oil from flowing from the compressor unit to the economizer vessel during shutdown. Other than the isolation valve needed for strainer cleaning, it is essential that the strainer be the last device in the economizer line before the compressor. Also, piston-type check valves are recommended for installation in the economizer line, as opposed to disc-type check valves. The latter are more prone to gaspulsation-induced failure. The isolation and check valves and strainer should be located as closely as possible to the compressor, preferably within three feet.

RXF ROTARY SCREW COMPRESSOR UNITS ENGINEERING DATA

ECONOMIZER RATINGS For refrigeration plants employing multiple compressors on a common economizing vessel, regardless of economizer type, each compressor must have a back-pressure regulating valve in order to balance the economizer load, or gas flow, between compressors. The problem of balancing load becomes most important when one or more compressors run at partial load, exposing the economizer port to suction pressure. In the case of a flash vessel, there is no need for the redundancy of a back-pressure regulating valve on the vessel and each of the multiple compressors. Omit the BPR valve on the flash economizer vessel and use one on each compressor, as shown in Figure 6.

CAPACITY and BRAKE HORSEPOWER RATINGS WITH DIRECT EXPANSION OR SHELL and COIL ECONOMIZERS PROCEDURE - Determine capacity (TR) and brake horsepower (BHP) from the non-economized, standard rating tables for the appropriate refrigerant (R717 or R22). Multiply these ratings by the capacity and shaft horsepower increase multipliers below for the appropriate refrigerant. Apply any other correction factors (subcooling, superheat or liquid injectionor 50 Hz) using instructions from Page 7.

DIRECT EXPANSION OR SHELL and COIL ECONOMIZER RATING INCREASE MULTIPLIERS R-717

R-22

NOTE: Increase multipliers are based on liquid subcooling by either direct expansion or shell and coil economizer. Use of the increase multipliers results in ratings based on 10°F suction superheat with the superheat enthalpy not contributing to the refrigeration effect, no liquid subcooling from condenser or other external source, and 10°F small temperature difference in heat exchanger. No allowance for vapor line pressure drop is included in the resulting ratings.

PERCENT LOAD The curve, above, is based on a 20°F linear drop in condensing temperature from full load to 10% of full load. This curve is applicable for R-717 (85°F to 105°F) full-load condensing temperature) and R-22 (95°F to 115°F) full-load condensing temperature). It is not applicable if condensing temperature does not drop with compressor unloading as in the following examples: 1. Water-cooled condensing temperatures cannot fall below entering water temperature. 2. Single compressor unloading on a multiple compressor system will have a negligible effect on system condensing temperature. 3. No condensing temperature drop will occur if condenser fans are cycled off as the load decreases.

STANDARD LUBRICATION SYSTEM LIMITS - HIGH STAGE The standard system for compressor operation without a lube oil pump may be used on high stage applications shown in the clear area of the graph. The optional demand oil pump is required only on low differential pressure applications shown in the shaded area of the graph. Where condensing temperatures fluctuate into the shaded area only on an occasional basis in the winter, the demand pump avoids unnecessary consumption of pump horsepower.

MOTOR SELECTION and STARTING TORQUE

STARTING TORQUE FOR SPECIFIC COMPRESSOR

Motors must be sized adequately for all expected operating conditions since start-up, pull-down, and load variations quite often require significantly more horsepower than nominal design.

Multiply the starting torque value from high stage or booster curves at 100% of normal run speed by starting torque multiplier for appropriate compressor size. MOTOR/COMPRESSOR TORQUE

Motor starting torque capacity must also be considered, especially when other than across-the-line start is employed. Motor starting and pull-up-torque must be at least 20% greater than compressor requirements at maximum expected start-up conditions. Refer to the torque data.

Assure that the motor STARTING and MINIMUM PULL-UP TORQUE capabilities will exceed the compressor requirements at the anticipated condition that will be experienced during normal starting.

NOTE: Motor starting torque varies considerably with various manufacturers - obtain specific torque data for the motor being used.

NOTE: Wye-delta and auto transformer (reduced voltage) motor starting methods drastically effect the starting torque available from motors as indicated: Across-the-Line Auto Transformer Wye-delta
