1.3 Single Screw Compressor Air Cooled Single Screw Chiller With leading technology, McQuay s semi-hermetic single screw compressor has such features as highefficiency, saving energy, stability, quietness, few operation components and long durability. Few operation components The single screw compressor is equipped with only five moving components: a screw, two gate rotors and two loading slide valve. The screw rotor outside is special treated, and the gate rotor is equipped with eleven-tooth high strength compound material. Liquid durability and high reliability With an equalizing compression, the single screw reduces the bearing load extending the bearing life span. The gate rotor, which is made of high flexibility synthetic material, can keep exact and minimum clearance to ensure no friction can happen, which can improve unit s efficiency. The oil ejection and liquid ejection design to the compressor avoid the overheat gas decrease to a minimum, eliminating to decompose the oil and refrigerant, keeping the good properties of the oil and refrigerant. Easy to maintain The gate rotor is accessible through a removing cover plate, making an easy maintenance. Bearing durability The bearing durability of the single screw compressor is up to 5 times or more, compared to twin-screw compressor. Low noise and low vibration The single screw compressor performs a complete balance load in operation, so its vibration is near to zero and its noise level reaches the minimum of the industry standard. It does not contact metal to metal in compression, which eliminates high frequency noise. Special design discharge chamber eliminates discharge noise. Rate rotor and rotors The single screw compressor, with excellent unique design and special gate-rotor material, and no need for metal hermetic requirement between the gate-rotor and rotors, reaches zero-interval. The liquid refrigerant brings more effects as hermetic, lubricant and cooling material when the compressor rotors operate. What s more, its interval of the teeth is very little and the resistance is very low, which can improve the unit s efficiency. High-efficiency oil separator The system is equipped with a high efficiency oil separator up to 99.7% efficiency. This improved the reliability and one more improvement to compression operation. 7

Compression principles Suction Gas flows through the suction port into open ends of available grooves. As the screw rotates, gate-rotor teeth enter the seal grooves in sequence, refrigerant gas in chambers defined by three sides of the grooves, the compressor casing and the gate-rotor tooth surface. Compression Volume in each tooth chamber decreases as the screw rotates. Gas is continuously compressed until the groove leading edge passes the discharge port. Discharge Release of gas into the discharge chamber ends the compression cycle. Gas continues to be discharged until the gate-rotor reduces groove volume to zero. With two gate-rotors equalized on opposite sides of the screw, this process occurs twice with each screw revolution, doubling the compressor capacity of the unit. Axial force balance With opposing and equal suction pressure at both ends of the screw member, the huge thrust loads of twinscrew compressor design are eliminated. Radial force balance Gate rotors on both sides of the screw member compressing simultaneously completely balanced radial loading on the rotating screw, nearly eliminates bearing wear. This is a sharp contrast with twin-screw designs whose bearing size is limited and higher loads directly impact bearing life. Twin-screw is with unbalance loading Without balance compression, the twinscrew increases axial loads and radial loads, and it increases abrasion, which affects the bearing life. Axial force balance Radial force balance Balanced stress with the single screw Unbalanced stress with the dual screws 8

Unload area Recommended area 4.2 System Water Volume It is important to have adequate water volume in the system to provide an opportunity for the chiller to sense a load change, adjust to the change and stabilize. As the expected load change becomes more rapid, a greater water volume is needed. The system water volume is the total amount of water in the evaporator, air handling products and associated piping. If the water volume is too low, operational problems can occur including rapid compressor cycling, rapid loading and unloading of compressors, erratic refrigerant flow in the chiller, improper motor cooling, shortened equipment life and other undesirable occurrences. For normal comfort cooling applications where the cooling load changes relatively slowly, we recommend a minimum system volume. Calculation of the water volume (m 3 ) is as below: L = P 0.0068 where: L = minimum water volume (m 3 ) P = nominal cooling capacity (kw) 4.3 Water flow range Model MHS/MCS 50 60 70 80 100 120 135 150 170 185 Water Flow Rate Range m 3 /h 25~40 25~48 32~56 34~66 43~85 51~99 55~107 63~124 75~147 78~153 Model 200 220 235 260 285 310 330 350 380 Water Flow Rate Range m 3 /h 87~169 95~183 101~198 114~224 120~235 129~251 140~273 157~306 165~321 11
