AC-AC Voltage Regulator Conditioning Converter with Three Control Schemes

In this paper, a comparative study of modified phase-angle, extinction-angle, and pulse width modulation control techniques for the purpose of power factor improvement of single-phase AC-AC voltage regulators have been illustrated as applied to a singlephase ac voltage converter by an example of the widely used single-phase induction motor as a dynamic load. Observations on power factor, displa...

Shunyata Denali AC Power Conditioning System

That doctor, whose days were filled with analyzing and interpreting the tiny electrical signals emitted by the heart, spent his evenings enjoying music through a high-end system. Discovering that Shunyata’s Triton AC conditioner improved the low-level resolution of his audio system, he surmised that the Triton may allow him to more clearly see the heart’s tiny electrical signals in a clinical s...

Fully Fresh Air Air-conditioning System Equipped with Double Heat Pipe Based Heat Recovery Technology

The using of double heat pipe based heat exchanger (HPHX) in a conventional fully fresh air air-conditioning (AC) system was examined in the present study. The fabricated HPHXs were tested under the actual conditions and the measured data were used to study the performance of the existing AC system (System A) and AC system equipped with the double HPHX (System B) for a yearly operation through ...

Optimization of Vehicle Air Conditioning Systems Using Transient Air Conditioning Performance Analysis

The National Renewable Energy Laboratory (NREL) has developed a transient air conditioning (A/C) system model using SINDA/FLUINT analysis software. It captures all the relevant physics of transient A/C system performance, including two-phase flow effects in the evaporator and condenser, system mass effects, air side heat transfer on the condenser/evaporator, vehicle speed effects, temperature-d...
