5 Equipment Overview FORM EG1 (1115) YORK YCRL Remote Condenser Liquid Chillers provide chilled water for all air conditioning applications that use central station air handling or terminal units. They are self-contained and are designed for indoor (new or retrofit) installation. Each unit includes hermetic scroll compressors, a liquid evaporator, and a user-friendly, diagnostic Microcomputer Control Center all mounted on a rugged steel base. Remote condensers (model VDC) are available separately from Johnson Controls. The units are produced at an ISO 9001 registered facility. The YCRL chillers are rated in accordance with AHRI Standard 550/590. GENERAL The chiller will be completely assembled with all interconnecting refrigerant piping and internal wiring, ready for field connection to a remote condenser. The unit will be pressure-tested, evacuated, and charged with a nitrogen holding charge, and York V (POE) synthetic oil. The unit can be covered with an optional overspray coat of Caribbean Blue enamel. Units are designed in accordance with NFPA 70 (National Electric Code), ASHRAE/ANSI 15 Safety Code for Mechanical Refrigeration. All units are produced at an ISO 9001 registered facility. All YCRL condensing units are rated in accordance with AHRI Standard 550/590 at AHRI conditions. COMPRESSORS The chiller has suction-gas cooled, hermetic, scroll compressors. The YCRL s compressors incorporate a compliant scroll design in both the axial and radial direction. All rotating parts are statically and dynamically balanced. A large internal volume and oil reservoir provides greater liquid tolerance. Compressor crankcase heaters are also included for extra protection against liquid migration. All compressors are mounted on isolator pads to reduce transmission of vibration to the rest of the unit. REFRIGERANT CIRCUIT Two independent refrigerant circuits will be furnished on each unit. All piping will be copper with brazed joints. The liquid line will include: a shutoff valve with charging port; sightglass with moisture indicator; thermal expansion valve; solenoid valve; and high-absorption removable-core filter drier.

12 FORM EG1 (1115) Refrigerant Flow Diagram Low-pressure liquid refrigerant enters the evaporator tubes and is evaporated and superheated by the heat energy absorbed from the chilled liquid passing through the evaporator shell. Low-pressure vapor enters the compressor where pressure and superheat are increased. High-pressure vapor is passed through a remote condenser where heat is rejected to the air flow passing through the coil. 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 evaporator. 12 JOHNSON CONTROLS

15 Selection Data FORM EG1 (1115) GUIDE TO SELECTION Complete water chilling capacity ratings for YORK YCRL condensing units 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 Johnson Controls office. SELECTION RULES 1. Ratings - All YCRL ratings are in accordance with AHRI Standard 550/590, at the AHRI standard condi tions. Ratings not at standard AHRI conditions are rated in accordance with AHRI rating procedures. These ratings may be interpolated but extrapolated. 2. Cooling Water Quantity - Ratings are based on 10ºF chilled water range with the evaporator at sea level. Use the chilled water correction factors (below) for other ranges except as limited by water pressure drop, minimum or maximum water flows for the evaporator. 3. Fouling Factors Ratings are based on evaporator fouling factor. For other fouling factors, consult the table below or contact your Johnson Controls representative. EVAPORATOR CORRECTION FACTORS FF=TEMP SPLIT TONS COMPR KW TONS COMPR KW Ethylene Glycol Correction Factors The following factors are to be applied to the standard ratings for units cooling ethylene glycol.

16 FORM EG1 (1115) Selection Data (Cont'd) METHOD OF SELECTION If the duty requires a 10ºF (6 C) range on the evaporator, see Ratings. For water ranges other than 10ºF (6 C), use the following procedure. Line sizes can be determined by reviewing York DX Piping Guide ES2. 1. Determine capacity required from the following formula: Capacity (Tons) = GPM x Chilled Water Range ( F) After applying any fouling factor corrections, the actual condenser heat rejection may be determined as follows: Heat Rejection (MBH) = Heat Rejection (Btuh) 1000 = (Tons x 12) = (kw x 3.415) 3. Size condenser using manufacturer s recommendations. SAMPLE SELECTION Water Cooled Chiller (YCRL) GIVEN Chill 200 GPM of water from 56ºF to 44ºF and evaporator fouling factor with 125 F saturated discharge temperature. FIND The required unit size capacity, kw, EER, and water pressure drop, and the condenser MBH heat rejection. SOLUTION: 1. Chilled water range = 56ºF - 44ºF = 12ºF and correction factors are for Tons and for kw for the evaporator. Capacity (Tons) = GPM x Chilled Water Range ( F) 24 = 200 x = 100TR 2. From the rating, a model YCRL0118HE has a capacity range required. For the evaporator leaving water temperature of 44ºF and a saturated discharge temperature of 125 F, the unit capacity rating table indicates: Tons = KW = EER = 11.1 Correcting for the 12ºF chilled water range: Tons = x = TR KW = x = kw 16 JOHNSON CONTROLS

18 FORM EG1 (1115) Selection Data (Cont'd) REFRIGERANT PIPING General When the unit has been located in its final position, the unit piping may be connected. Normal installation precautions should be observed in order to receive maximum operating efficiencies. System piping should conform to the York DX Piping Guide form ES2 or ASHRAE refrigeration handbook guidelines. All piping design and installation is the responsibility of the user. JOHNSON CONTROLS ASSUMES NO WARRANTY RESPONSIBILITY FOR SYSTEM OPERATION OR FAILURES DUE TO IMPROPER PIPING OR PIPING DESIGN. All filter driers, sight glasses, expansion valves and liquid line solenoid valves are factory installed on each refrigerant circuit. Interconnecting refrigerant piping and refrigerant charge are supplied and installed by others. Table 1 lists refrigerant line connections sizes per unit model number.

Be sure to review form ES2. Considerations should be given to: 1. Discharge line pressure drop due to refrigerant flow. 2. Discharge line refrigerant velocity for oil return. 3. Liquid line pressure drop due to refrigerant flow. 4. Liquid line pressure drop (or gain) due to vertical rise of the liquid line. To ensure a solid column of liquid refrigerant to the expansion valve, the total liquid line pressure drop should never exceed 40 PSIG (2.8 barg). Refrigerant vapor in the liquid line will measurably reduce valve capacity and poor system performance can be expected. To allow adequate oil return to the compressor, discharge risers should be sized for a minimum of 1000 FPM (5.08 m/s) while the system is operating at minimum capacity to ensure oil return up the suction riser. 18 JOHNSON CONTROLS

19 Selection Data (Cont'd) FORM EG1 (1115) Chiller Below Condenser On a system where the chiller is located below the condenser, the discharge line must be sized for both pressure drop and oil return. In some cases a double discharge riser must be installed to ensure reliable oil return at reduced loads. Condenser Below Chiller When the condenser is located below the chiller, the liquid line must be designed for both friction loss and static head loss due the vertical rise. The value of static head loss of 5 PSI/ft. (3.4 kpa/30 cm) must be added to the friction loss pressure drop in addition to all pressure drops due to driers, valves, etc. OIL TRAPS All horizontal discharge lines should be pitched at least 1/4 per foot (2 cm/m) in the direction of the refrigerant flow to aid in the return of oil to the chiller. All discharge lines with a vertical rise exceeding 3 feet (.91 meters) should have a P trap at the bottom and top of the riser. Discharge lines with a vertical rise exceeding 25 feet (7.6 meters) should be trapped every 15 feet (4.6 meters). REFRIGERANT CHARGE The chiller is charged and shipped with a dry nitrogen holding charge. The operating charge for the chiller, remote condenser and refrigerant piping must be weighed in after all refrigerant piping is installed, leak checked, and evacuated. Final adjustment of refrigerant charge should be verified by subcooling values (refer to IOM section on Pre-Startup for checking subcooling).

22 FORM EG1 (1115) Application Data UNIT LOCATION Chillers are designed for indoor installation. Units should be located away from noise-critical areas. Service clearance must be allowed and include space for remov ing condenser tubes. A doorway or window can sometimes provide space for tube removal. Units should be installed indoors where they are not exposed to rain or water splash. Chillers should be located near a drain. The use of chillers in corrosive, dusty or ex plosive atmospheres should be avoided unless the unit is properly protected. A unit located in a clean room will run best, require least maintenance, and last longest. Heat or ventilation may be required to maintain the ambient between 40 F and 115 F (4.4 C and 46.1 C). UNIT ISOLATION The chiller foundation must be rigid to reduce vibration transmission to a minimum. All upper story installations should use vibration isolators under the unit base. To main tain isolator efficiency, no mechanical ties should be made to the building. Properly selected flexible connectors and piping isolators are recommended. All the above recom mendations will help to reduce vibration transmission and result in a quieter operation. FIELD CONNECTED WATER PIPING Piping must comply in all respects with applicable local plumbing codes and ordinances. In no case should the unit support the weight of connecting piping. Since elbows, tees, and valves increase pressure drop, all piping should be kept as simple as possible. Hand stop valves should be installed where required to facilitate servicing. Piping to the inlet and outlet connections of the evaporator and condenser may include high-pressure rubber hose or piping loops to ensure against water pump transmission of vibration. Facilities should be provided for measuring temperature and pressure in the evaporator and condenser field water pip ing. Drain connections should be provided at all low points to permit complete drainage of the evaporator(s) and system piping. This is especially im portant if the unit is located in an unheated room where freezing could prevail. Water lines subjected to ambient temperatures below freezing may require heater cables or antifreeze (by others). Water loops should contain provisions for venting. A strainer, preferably 40 mesh, should be installed in the evaporator inlet line, located where it will protect the circulating pump and the heat exchanger tube bundles. It should be determined that the maximum water pressure at the evaporator does not exceed the maximum design working pressure. The water circulating pump should be located on the inlet side of the heat exchanger. If, however, space does not permit this, the pumps may be located in the outlet water piping. The net positive suction head must be considered when applying pumps. 22 JOHNSON CONTROLS

23 Application Data (Cont'd) FORM EG1 (1115) FIELD WIRING All field wiring must comply with the National Electric Code and all applicable local codes. YORK liquid chiller units are factory wired for optimum reliability. Therefore the unit controls must not be modified without ex pressed written consent by Johnson Controls. The use of a simple switch or timer from a remote point is permitted; but it must be connected to the unit panel at points expressly indicated for that purpose. REFRIGERANT RELIEF PIPING Each chiller is equipped with pressure relief valves. The purpose of the relief valves is to quickly relieve excess pressure of the refrigerant charge as a safety precaution in the event of an emergency such as a fire. Sized to the requirements of applicable local codes, a vent line must be run from the relief valve to the outside of the building. Vent piping must be arranged to avoid imposing a strain on the relief valves and should include flexible connections. The low side relief valve is located on the suction line. It has a pressure setting of 400 PSIG (27.6 bar) and a capacity of 28.6 lbs. air/min ( l/s). The 0064, 0074, and 0096 units have additional relief valves on the discharge line(s) in lieu of compressor internal relief. The valve has a pressure setting of 650 PSIG (44.5 barg), a capacity of 44.6 lbs air/min (277 l/s) and a 1/2 flare connection. JOHNSON CONTROLS 23
