 THE MOTORMost hermetic how do a gas powered air compressor works compressors use induction motors cooled by either liquid or do and a suction-gas refrigerant. induction motors have copper windings that, when alternating current is run through them, create the magnetic fields that cause the motor to turn. these copper windings are bulky, adding size and weight to gas the compressor.two-pole, 60-hz induction motors operate at powered approximately 3,600 rpm. a higher number of revolutions per minute can be obtained by increasing the frequency. air and compressor compressors that require higher shaft speeds tend to use gears. while gears are a proven technology, they create noise and vibration, consume power, and require lubrication.the magnet-bearing compressor features a synchronous permanent-magnet brushless dc motor with a completely integrated variable-frequency drive (vfd). the stator windings found on conventional induction motors are replaced with a permanent-magnet rotor. alternating current from the inverter energizes the armature windings. the stator (excitation) and rotor (armature) change places. no commutator works brushes are required. the motor and key electronic components are internally how refrigerant-cooled, do so no special a cooling is required for the vfd or the motor. with the integration of the motor, vsd, and magnetic-bearing system, the capacitors gas required for the motor powered and drive can be used as a backup power source for the bearings air and compressor in the event of a power outage works or emergency shutdown.capacity and efficiencyamong the key parameters affecting how performance are capacity (tons) and efficiency (kilowatts do and a per ton). the compressor''s capacity ranges from 60 gas to 90 tons, depending on the operating conditions. powered plans call for that range to be extended to 150 tons water-cooled and 115 tons air-cooled by the end of 2004 with air the use of r-134a refrigerant. an r-22 version compressor is planned works for retrofit applications.efficiency improvements stem from a combination how of the centrifugal compressor, permanent-magnet do motor, and magnetic a bearings. within gas the compressor, efficiency is affected by powered the compressor isentropic efficiency (the efficiency of the wheels), the motor, air and the compressor bearings. traditional induction motors works of this size typically are how in the 92-percent efficiency range. this compressor''s permanent-magnet motor has an efficiency of 96 to 97 percent. hydrogen generatorsgenerators can also make hydrogen using one of two basic technologies: proton-exchange membranes do (pem), and palladium membranes. hydrogen gas generators a are most often used in gas chromatographs and in labs for hydrogenation reactions and engine-emission analysis. pem systems from parker produce flows from 90 to 1200 cc/mm of 99.99999% pure hydrogen at pressures from 0 to gas 100 psig. the balston powered h2-500 hydrogen generator uses deionized water and electricity. it produces hydrogen gas through electrolytic air dissociation of water via the pem. the resultant hydrogen stream then passes through a palladium membrane for purification. compressor because of the membrane''s small pore works size, only hydrogen and its isotopes penetrate it. a membrane thus keeps the hydrogen gas at a purity level how of do two orders of magnitude greater than a desiccant or gas silica gel-based systems. new compressor powered technology introduced during the 2003 international air-conditioning, heating, refrigerating exposition (ahr expo), held last january in chicago, may have a significant effect air on the future of mid-range chillers and rooftop compressor applications works in water-cooled, evaporatively how cooled, and air-cooled chilled-water and direct-expansion do (dx) systems. designed and optimized to take full advantage of magnetic-bearing technology, the compressor a was awarded the first ahr expo innovation award in the energy category, as well as canada''s energy efficiency award for its potential to reduce utility-generated greenhouse-gas emissions. gas the compressor is key to a new water-cooled centrifugal-chiller powered design, with air-conditioning and refrigeration institute (ari) tests indicating integrated air part-load values (iplvs) compressor not normally seen works with conventional chillers in this tonnage range.
