A new compressor product is introduced which fulfills the market need for a low cost, high efficiency, durable air conditioning and heat pump compressor for the 1.5 to 2.0 ton capacity range. ·A review of compressor technologies has indicated the optimum compressor for this application would incorporate the durability and versatility of a piston compressor while employing the cost and noise adv...

Structural steels with very high strength levels are often referred to as ultrahigh-strength steels (UHSS). The usage of UHSS has been extensively studied in aerospace industries and offshore platforms. In this study, medium carbon low alloy steel (AMS6305) was thermomechanicaly treated to obtain an ultra-high strength bainitic steel for aircraft engine compressor disk. A novel themomechanical ...

A novel CMOS 4-2 compressor using pass logic is presented in this paper. An XOR-XNOR combination gate is used to build the circuit while totally eliminating the use of inverters. The total power dissipation has been cut down to a minimum while providing the full output voltage swing at all nodes in the circuit. Furthermore, the complete circuit is implemented with a bare minimum of 28 transistors.

The paper proposes architectures of 5:3 compressor designs for low power multiplication purposes. The architecture explores the essence of two transistor multiplexer design and novel two transistor XOR gates for the proposed topology with least number of transistors for logic level implementation. The modified and proposed compressor designs reduce the stage delays, transistor count, PDP (power...

this paper presents the design procedure and implementation results of a proposed hardware which performs different satellite image compressions using fpga xilinx board. first, the method is described and then vhdl code is written and synthesized by ise software of xilinx company. the results show that it is easy and useful to design, develop and implement the hardware image compressor using ne...

Very few reports have been presented to date on the noise and vibrational characteristics of oil injected screw compressors. This time. a series of extensive experimental analysis is performed. It includes the measurements and analysis of compressor casing vibrations. rotor shafts vibrations, torsional <rotational) vibrations. suction and discharge gas pulsations. pressure trans~ ient in one th...

The paper extends a mean value model of a parallel turbocharged internal combustion engine with a crank angle resolved cylinder model. The result is a 0D engine model that includes the pulsating flow from the intake and exhaust valves. The model captures variations in turbo speed and pressure, and therefore variations in the compressor operating point, during an engine cycle. The model is used ...
