| 20120108160 | HEATING, VENTILATING, AIR CONDITIONING, AND REFRIGERATION NOISE REDUCTION SYSTEM - Embodiments of a noise reduction system for use in heating, ventilating, air conditioning, and refrigeration (HVACR) systems are provided. The noise reduction system may include a barrier to be placed over an air inlet of an HVACR base unit. The barrier, consisting of two rows of equally spaced structures, may permit the passage of air therethrough while preventing the escape of noise from the base unit. The noise reduction system may also include one or more resonance chambers placed atop the base unit and a structure placed adjacent the base unit. Noise coming from the base unit may be redirected by the structure toward the resonance chambers, which are configured to attenuate the noise. | 05-03-2012 |
| 20120067965 | CONTROL SYSTEMS AND METHODS FOR MODULAR HEATING, VENTILATING, AIR CONDITIONING, AND REFRIGERATION SYSTEMS - Embodiments of a modular air conditioning (AC) unit include a base unit, a blower mounted to the base unit, and at least one heat exchanger module assembled to the base unit and communicatively coupled to the blower to form a modular AC circuit. The modular AC unit also includes a controller communicatively coupled to at least one component of the modular AC circuit and adapted to independently control operation of each of the components of the modular AC circuit. | 03-22-2012 |
| 20120042979 | AIRCRAFT HOSE RETRIEVAL SYSTEM - The present embodiments are directed towards the transfer, retrieval and storage of flexible materials. In one embodiment, a system is provided that generally includes a hose retrieval system having a first hose gripper assembly. The first hose gripper assembly includes a pair of first grippers configured to move between a first open position and a first closed position in opposite crosswise directions relative to a longitudinal axis of a hose. Each first gripper includes a first L-shaped structure, and the first L-shaped structures are configured to overlap one another to define a first bending gap in the first closed position. | 02-23-2012 |
| 20110113801 | CONDENSER ASSEMBLIES FOR HEATING, VENTILATING, AIR CONDITIONING, AND REFRIGERATION SYSTEMS - Embodiments of a modular condenser unit are provided. The modular condenser unit may include a housing and a first condenser coil and a second condenser coil disposed within a volume of the housing. A fan may also be disposed in an end of the housing and adapted to draw air through at least one of the first condenser coil and the second condenser coil. In some embodiments, the first condenser coil and/or the second condenser coil may be micro-channel condenser coils. | 05-19-2011 |
| 20110113795 | MODULAR HEATING, VENTILATING, AIR CONDITIONING, AND REFRIGERATION SYSTEMS AND METHODS - Embodiments of a modular air conditioning (AC) unit include a base unit and a blower selected from a group of blowers configured for different cooling capacities. The module AC unit also includes at least one heat exchanger unit selected from a group of substantially identical modular heat exchanger units, the number of heat exchanger units being selected based upon the desired cooling capacity. The at least one heat exchanger unit and the blower are assembled to the base unit to form a modular air conditioning circuit. | 05-19-2011 |
| 20110030414 | AIR CONDITIONING SYSTEMS WITH OVERSPED INDUCTION MOTORS - Air conditioning systems including a refrigeration circuit having at least one fan or blower are provided. The air conditioning systems also include a multi-voltage induction motor coupled to the fan/blower. The multi-voltage induction motor includes motor windings adapted for use when the motor windings are wired in a first voltage wiring configuration and a second voltage wiring configuration, the second voltage being greater than the first voltage. The multi-voltage induction motor may be wired in the first voltage wiring configuration, and a variable frequency drive may be adapted to maintain an operating voltage to frequency ratio of the multi-voltage induction motor at approximately a voltage to frequency design ratio of the multi-voltage induction motor. Also provided are power conductors adapted to transmit power to the variable frequency drive at a voltage approximately equal to the second voltage for operation of the multi-voltage induction motor. | 02-10-2011 |
| 20100307178 | MODULAR HEATING, VENTILATING, AIR CONDITIONING, AND REFRIGERATION SYSTEMS AND METHODS - A modular air conditioning (AC) system including one or more AC modules is provided. The AC modules may be adapted to function individually or cooperatively as part of a modular system. The AC modules may be further adapted to connect in a variety of advantageous ways to facilitate the supply of conditioned air to a variety of downstream applications. | 12-09-2010 |
