HVAC systems

Back to 1902 when Willis carrier an american engineer who invented the first air condition,and behind his vision to solve a humidity problem found in a publishing company .carrier thought that in order to solve this humidity problem,the air inside the building must be treated by blowing it across chilled pipes.The air cooled as it passed across the cold pipes, and since cool air can’t carry as much moisture as warm air, the process reduced the humidity in the plant and stabilized the moisture content of the paper. Reducing the humidity also had the side benefit of lowering the air temperature .this was absolutely the born of a new technology by treating the air and make it cooler. with the passage of time air conditioning systems experienced a big progresses and changes with the concept and the ways the air is being treated and cooled using several engineering techniques adopted […]

TAB ( Testing adjusting & balancing ) and its procedure

Today modern environmental system require a proper procedure in order to maintain a proper functionality of an HVAC systems. whether cooling is performed by air or water ( Hydronic ), TAB is necessary in order to maximize the efficiency of an HVAC systems and to maintain its stability. the TAB procedure are usually performed via a certified contractors or a third party provider who has the expertise to perform the test and using the equipment’s. some HVAC contractors would have their own in house team and that depends on company policy and size . A certified tab technician or Engineers are those who are certified and accredited to perform this kind of test and they are particularily certified from two major company standards ,the NEBB ( national environmental balancing bureau ) USA & CSA  ( Commissioning specialist association ) UK ,which are the two major international standards available to train […]

CCTV and surveillance systems

What is CCTV cameras ? security systems or CCTV ( closed circuit television )  has become as essential as other thing in our lives. our property and premises are prone to be attacked if no proper security systems are well adopted in order to keep on surveillance on a continuous range. cctv systems are now available in different models and shapes, applications purposes and ready to keep on surveying during day and nights no matter what the weather condition is.  1- The 8 different types of cctv cameras available in the market .   2- Difference between analogue and digital CCTV : Many of us do not know the difference between analogue and digital cameras where both are behind the purpose of surveillance and providing security to our property. the main difference is that analogue CCTV cameras which use an analog video signal that is transmitted over coaxial UTP cable back […]

The first rule of any technology applied in business is that automation applied in an efficient way, that’s magnify the efficiency and reduce the energy consumption of your home , We all know the light dimmer when its first introduced in 1959 by Joel spira , An american inventor and entrepreneur who find a way to change the intensity of a light bulb, by changing its voltage waveform ,know as (priming voltage).Home automation exploit the same idea of dimming, but with further controls such as wireless, wired or powered line communication to control applications like ventilation , security as well as home automaton such as Washers ,Dryers ,Home entertainment etc… in the main principal the diagram below shows the main device in the home automation system : Home automation comes in different models and features that depends on the number of peripherals named as (addresses) that you want to control.basically […]
