HFO 1234 YF AS AN ALTERNATIVE REFRIGERANT FOR AUTOMOTIVE AIR CONDITIONING
ABSTRACT
HFO 1234 YF is a fluorinated hydrocarbon with the formula CH2=CFCF3. It has been replaced for R-134 as a refrigerant in Automobile Air Conditioner .HFO 1234 YF highly energy efficient, exhibits low toxicity, and can be potentially used in direct expansion automotive A/C systems with minimal design modifications . The Pres ....etc

Introduction

Solar air conditioning refers to any air conditioning (cooling) system that uses solar power. This can be done through passive solar, solar thermal energy conversion and photovoltaic conversion (sun to electricity). New solar air conditioning research and development program, which should develop and demonstrate multiple new technology innovations and mass production economies of scale. Solar air conditioning will play an increasing role in zero energy and energy-plus buildings design.

Abstract
This paper presents a new unified power-quality conditioningsystem (MC-UPQC), capable of simultaneous compensationfor voltage and current in multibus/multifeeder systems. Inthis configuration, one shunt voltage-source converter (shunt VSC)and two or more series VSCs exist. The system can be applied to adjacentfeeders to compensate for supply-voltage and load currentimperfections on the main feeder and full compensation of supplyvoltageimperfections on the other feeders. In the proposed configuration,all converters are connecte ....etc

Introduction

Due to varying conditions of heating, ventilating, cooling and dehumidification in atmosphere at various places, the air conditioning of automobiles is very essential. To maintain human comfort and improve internal atmosphere in an enclosed space, proper control of freshness temperature, humidity and cleanliness of air required.

In an automobile the air conditioning system involvs two main processes of heating and cooling. In the heating system, warm water from the engine cooling system is used. The heat required to warm t ....etc

ON LINE CONDITIONING AND MONITORING OF CUTTING TOOLS


In the recent years the manufacturing environment has undergone dramatic change. Because of the market pressure the trend is for saving cost of production. i.e. to produce more items of good quality in less time. For achieving this goal great consideration is given to CNC machining. Further it is a costly affair when product is not made to the quality specifications because of wear/tear or breakage of the tool. Unfortunately this happens without the machine operator suspecting any ....etc
