Learn More about Heat Pumps Nature created mankind, but with the advancement of technology, man is now trying to recreate nature. This may have its own advantages and disadvantages, but nowhere is this struggle more evident than in the field of environmental control for our inhabited interior spaces.
HVAC Design Principles and Major System Components Whether you're upgrading an existing system or building a new one, good knowledge of the principles of heating and air conditioning, and typical designs, will allow you to make wise decisions when the time comes. These principles, along with descriptions of typical components, are referenced here.
Heat Exchanger Designs Calculations for heat exchanger designs use heat transfer parameters such as convection heat transfer coefficients, overall heat transfer coefficients, and log mean temperature differences. These calculations are needed for shell and tube and double pipe heat exchangers, as well as other types.
Preliminary Heat Exchanger Design Example Design of heat exchangers is an iterative process, using the heat exchanger design equation to estimate the needed heat transfer area, based on an estimate of the overall heat transfer coefficient, specified heat load, and log mean temperature difference (from inlet and outlet temperatures).
The 2nd Law of Themodynamics In this article you will learn the two classical statements of second law, that is the Kelvin-Plank statement and Clausius statement. You will also learn some basics of thermodynamic entropy
How to Find Freon Leaks in Air Conditioners Freon leaks from air conditioners have adverse effects on our health. Keeping a check over Freon levels in air conditioners is important not only for health but for effective and smooth working of air conditioning units as well. Air conditioner leak detection is described in detail in this article.
