Specification General YORK YGAS series chillers are manufactured to the highest design and construction standards to ensure high performance, reliability and adaptability for all types of air conditioning installations. The units are designed for water cooling and to be located outside on the roof of a building or at ground level. The unit may contain one, two, or three refrigerant circuits. The units are completely factory-assembled with all interconnecting refrigerant piping and internal wiring, ready for field installation.

Prior to delivery, the unit is pressure tested, evacuated, and fully charged with refrigerant and lubrication oil. After assembly, an operational test is performed with water flowing through the cooler to ensure that each refrigerant circuit operates correctly. The unit structure is fabricated with heavy gauge, galvanized steel, which is coated with “Champagne” baked-on polyester powder paint.



Compressors The unit has accessible, direct drive semi-hermetic rotary twin-screw compressor(s). All rotating parts are statically and dynamically balanced to ensure high operational efficiencies and reliable performance. Stepless capacity control is achieved between 25% and 100% of full capacity for each compressor by regulating slide valve to fulfill the cooling load requirements. Motor - Motor cooling is provided by suction gas from the evaporator flowing across the motor. Redundant overload protection is provided using both internal thermistor and current overload protection on all three phases. Rotors -The rotors are housed in a cast iron compressor housing precision machined to provide optimal clearances for the rotors. Contact between the male and female rotor is primarily rolling on a contact band on each of the rotor’s pitch circle. This results in virtually no rotor wear and increased reliability, a trademark of the screw compressor. Housing - Cast iron compressor housing precisely machined for optimal clearances and superb efficiency. Entire compressor, from suction to discharge, has a Design Working Pressure (DWP) of 2.1MPa. Capacity Control - Microprocessor controls the load/ unload solenoid valve to drive the valve and achieve stepless and smooth capacity control from 100% to 25% of compressor capacity for each compressor. Isolation - Each compressor is mounted on isolator pads to reduce vibration transmission to the structure.



Evaporator The evaporator is a shell and tube, flooded type heat exchanger. A distributor trough provides uniform distribution of refrigerant over the entire shell length. A baffle plate is located above the tube bundle to prevent liquid refrigerant carryover into the compressor. The evaporator shell of each system contains a refrigerant relief valve. A 40mm diameter sight glass is installed at the appropriate position to allow visual inspection of refrigerant levels. The design working pressure is 2.3MPa for shell, 1.0MPa for tube side. The refrigerant side has a safety valve with trip pressure of 2.2MPa. The refrigerant side is manufactured and tested in accordance to China National Standard GB151. The removable compact water boxes are fabricated from steel. The design working pressure is 1MPa and the boxes are tested at 1.25MPa. Integral steel



water baffles provide the required pass arrangements. Stub-out water nozzle connections with flanges are welded to the water boxes. These nozzle connections are suitable for corresponding flanges, and are capped for shipment. Plugged 3/4”NPT drain and vent connections are provided in each water box. The evaporator shell is insulated with 19mm closed-cell material.



Condenser Coil -The fin and tube condenser coils are manufactured from seamless, internally enhanced, high-condensing coefficient, corrosion-resistant copper tubes arranged in staggered rows and mechanically expanded into corrosion resistant aluminum alloy fins with full height fin collars. The units also adopt Reversed “M” type Coil arrangement to achieve high efficiency heat transfer by optimizing the corner angle of the coils. A “silent night” mode can be provided by YGAS chiller. Customer can get the lower noise level by timing or manual driving the “silent night” on the control panel. The two speed fans equipped in chiller will switch to low speed automatically. Fans - The fans are dynamically and statically balanced, direct drive with corrosion resistant glass fiber reinforced composite blades molded into full airfoil cross section, providing vertical air discharge from extended orifices for efficiency and low sound. Motors - The motors are high-efficiency, direct drive, 6-pole, 3-phase, Class “F”, current overload protected with double sealed, permanently lubricated ball bearings.



Electronic Expansion Valve YGAS series chillers are equipped with advanced electronic expansion valve to ensure accurate control at various load conditions. The electronic expansion valve is able to inject precise amounts of liquid into the evaporators for the system. The electronic expansion valve modulation is electronically controlled by activation of the AST stepper motor. The motor is a 2-phase bi-polar type, which stays in position unless power pulses from a driver to initiate the two discrete sets of motor stator windings for rotation in either direction. The direction depends on the phase relationship of the power pulses, whose value again is decisive for the travel. The motor operates the spindle, where rotating movements are transformed into linear motion by the transmission in the cage assembly.

Refrigerant Circuits



Power and Control Panels



Unit piping is TP2 copper with brazed joints. The liquid line includes: electronic expansion valve, angle valve, ball valve, sight glass with moisture-indicator, drier filter, etc. The refrigeration system is pressure-tested, leak-tested, and evacuated then charged with refrigerant. The entire suction line and the liquid line between the expansion valve and the cooler, are insulated with flexible, UV stable color coordinated closed-cell, foam insulation.



All controls and motor starting equipment necessary for unit operation are factory wired and function tested. 1 and 2 circuit units have one control panel respectively, and 3 circuit unit has two control panels (main and auxiliary). The panel enclosures are designed to IP55 and manufactured from powder coated galvanized steel. The surface is painted YORK Champagne.



There are two high pressure sensors, which are equipped to test discharge pressure and oil pressure, and a low pressure sensor, to test the evaporator pressure. High pressure switch and low pressure switch are also installed in the system pipe to protect the compressor.



Oil Separator Besides the high efficiency internal oil separation in each compressor, there is an external centrifugal oil separator used to avoid lubrication oil mixing with the refrigerant in the system ensuring maximum heat exchange and compressor lubrication. The external oil separators, with no moving parts and designed for minimum oil carry-over, are mounted in the discharge line of the compressor. DWP of the oil separator can reach 2.26MPa.



The control panel is divided into a power and a control compartment. Power and control sections have separate hinge, latch and gasket sealed doors for ease of maintenance and safety of the operators. Each power compartment comprises of compressor starting contactors, control circuit serving compressor capacity control, compressor contactor coils. The compressor motor protection can relay the compressor current to the microprocessor, and it can also protect from phase reversal and lack of phase for compressor power supply. The control section contains microcomputer keypad, HMI and I/O board.



Microprocessor All the control logic and devices which are factory wired will be fully tested in the factory. A LCD display screen and user-friendly keypad is mounted in front of the HMI.



The oil flows from the oil separator into the compressor through an oil filter and a solenoid valve at high pressure. This high pressure “oil injection” forces the oil into the compressor, where it is fed to the bearings and rotors for lubrication. After lubricating the bearings, differential pressure causes the oil to be automatically injected through orifices on a closed thread near the suction end of the rotors. It lubricates the rotors as well as provides an oil seal against leakage around the rotors to ensure refrigerant compression efficiency.



Oil Eductor Oil eductor circuit is provided to properly manage the amount of oil in the evaporator and transfer oil from the evaporator to compressor with the “jet pump” principle. Returning oil to the compressor prolongs its life and also improves the performance of the evaporator.



Oil Cooling Oil cooling is provided by routing oil from the compressor through several of the bottom rows of the condenser coils, where it is cooled, then sent back to the compressor.
