 With Coleman 4 HP Pontoon Air Compressor Model CT4090410 the integration of the motor, 4 vsd, and magnetic-bearing system, hp the capacitors pontoon required for the motor and drive can be air used as a backup power source for the bearings in the event of compressor a power outage or emergency shutdown.capacity and efficiencyamong the key parameters affecting model performance are ct4090410 capacity (tons) Coleman 4 HP Pontoon Air Compressor Model CT4090410 and efficiency (kilowatts 4 and hp per ton). the compressor''s pontoon capacity ranges air from 60 compressor to 90 tons, depending on the operating conditions. model plans call for that range to be extended to 150 tons water-cooled ct4090410 and coleman and 115 tons air-cooled by the end of 2004 with the 4 and hp use of r-134a refrigerant. an r-22 version is planned for retrofit applications.efficiency improvements stem from a combination of the centrifugal pontoon compressor, permanent-magnet motor, and magnetic bearings. within the compressor, efficiency is affected by the compressor isentropic efficiency (the efficiency air of the wheels), the motor, and compressor the bearings. traditional induction motors of this size typically are in the 92-percent model and ct4090410 efficiency coleman range. this 4 compressor''s permanent-magnet hp motor has an efficiency of 96 to 97 percent. most pontoon air-cooled products (including chillers, air rooftop compressor units, and condensing model units) use dx evaporators. most dx systems allow oil to travel through the refrigeration ct4090410 circuit and back to the compressor oil coleman sump. great care must be taken during design 4 to provide hp oil return, particularly at part pontoon load, when refrigerant flow rates are reduced.water-cooled air chillers often use flooded evaporators. compressor in a flooded evaporator, even small amounts of oil can coat evaporator tubes model and significantly ct4090410 and coleman diminish chiller performance. 4 this hp can lead to an elaborate oil-recovery system. magnetic bearings eliminate pontoon the need for these systems and oil management in general. in fact, the only required regular air maintenance of the compressor and model compressor is the quarterly tightening of the terminal screws, the annual ct4090410 blowing coleman off of dust and cleaning of the 4 boards, and the changing of the capacitors hp and pontoon and air every five years. complete service compressor agreements and extended maintenance contracts can be provided by the manufacturer. this article describes this new compressor technology model and its first use in ct4090410 an ari-certified chiller design.the bearingstraditional coleman centrifugal compressors use roller bearings 4 and hydrodynamic hp and pontoon and air bearings, both of which consume power and require oil compressor and a lubrication system. recently, ceramic roller bearings, model which avoid issues related to oil and reduce power ct4090410 consumption, were coleman introduced to the hvac industry. the lubrication of these bearings is provided 4 by the refrigerant itself. hp (1)magnetic-bearing technology is pontoon significantly air different. a digitally controlled compressor magnetic-bearing model system, consisting of both permanent magnets and electromagnets, replaces ct4090410 conventional lubricated bearings. coleman the frictionless 4 and hp and pontoon compressor air shaft is the compressor''s only moving component. it rotates compressor on a levitated magnetic model cushion (figure 1). magnetic bearings--two radial and one axial--hold the ct4090410 shaft in position (figure 2).
