Thermo Acoustic Engines

abstract

Environmental priorities are forcing chloro -fluorocarbons out of market place thereby creating a new demand for cooling technologies. This paper presents an outcome of researches done to design, construct and evaluate a CFC free refrigeration system. A prototype Thermo acoustic cooling system utilizing high amplitude sound waves in an inert gas is discussed.

There are all kinds of DIY air conditioners you can make at home. Some are easier to make than others, but they all work quite well. The 5 we came up with will keep you cool, and they only cost a few cents per day to run. Most of them can be made for $15 or less.

Here s what one of our readers had to say about one of the AC s below I know from personal experience. Using this little contraption in place of our AC last Summer saved us $$200 a month

These are meant to be room, or space coolers. Some of them can be used in your car if th ....etc

diy air conditioner report

Summer is here and the sun s golden rays are finally smacking us upside the head and roasting us crisp faster than you can say heat stroke. With winter at least six months away (unless you re reading this late, sorry) there has to be some way to cool down without spending all your hard-earned shekels on a pricey new air conditioner. Luckily, there is. For just $19.73, you can make a DIY air conditioner using materials that you probably have in your house. Assuming you like to party and keep large bags of ice in y ....etc

Thermo acoustic Refrigeration is based on the principles of creation of temperature gradient from sound waves and this theory was first developed in 1960s. Unlike vapour compression system, Thermo acoustic engines uses inert gases which is safe and no adverse effect on the atmosphere like the depletion of ozone layer and global warming.

Even though acoustic Refrigeration is efficient and cost effective its commercial application is warranted the need of more R&D efforts for technology up gradation and standardization without which its eff ....etc
