An HVAC system is designed to keep the occupants of offices, tower blocks and retail properties happy and healthy across the world. However, sometimes, your unit will need a helping hand to keep itself in top condition.
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.
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.
Air conditioners are not just about the on/off button and remote control. For an engineer, they mean a lot more: they are machines that must be understood to achieve efficient performance.
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.
The power used in running a building’s Heating, Ventilation and Air Conditioning (HVAC) is quite substantial, so any measures to improve its efficiency will save energy and cash. An upgrade of the HVAC system can be carried out by replacing the old worn components with modern more efficient units.
Wall mounted air conditioner units have advantages and disadvantages. In this article, we will talk about the installation and maintenance of wall mounted room air conditioners and their comparison with other popular types of air conditioning units.
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.
Using UV lamps for improving the air quality indoors is the right solution for killing airborne bacteria and removing other pollutants. Read to learn the best practices for installing UV lamps in air handlers.
A chiller unit requires water, so the term “chiller water treatment” is important for the life of the system – or is it? Being a closed loop system, is treatment for chilled water really needed? If so, what are the available methods of treatment?
