CONNECTIONS An air conditioning system is made up of
AND four major parts. The evaporator,

these air conditioner components works
hand in hand with the others and has a
specific purpose which is to keep your
air conditioner functioning smoothly.

The first major parts in air-conditioning systems is Next, condenser coil. The condenser

While the second major component in air-
conditioning system is compressor. The compressor 51
is the workhorse of air conditioning and perhaps the
most crucial of all air conditioner components. The
compressor is installed in the outside unit of central
and split systems. The compressor absorbs the
most of an air conditioner's energy, and it is typically
the most expensive component. The compressor's
function is to compress the refrigerant, which was a
heated vapor when it arrived to the compressor,
into a hot compressed liquid. This is then chilled and
expanded again as the air conditioning operation
continues to remove heat from the inside air.

CODES AND
SYSTEM

REGULATIONS

ASHRAE Standard 62.1-2010, Ventilation for Acceptable
Indoor Air Quality, including its published Addenda, is
the national consensus standard for outside air
ventilation. This guideline, which is frequently included
into state and municipal construction codes, defines
the volumes of outside air that must be given to
various parts of the school via natural or mechanical
ventilation systems, including rooms, gymnasiums,
cafeteria, and other special use facilities.

Among other things, several state codes include
minimum energy efficiency criteria, ventilation controls,
pipe and duct insulation and sealing, and system size.
Furthermore, several states and cities have established
ventilation and other indoor air quality regulations that
must be met.

ASHRAE guidelines are required in the design.

62.1-2007 for outdoor air ventilation and

Conclusion

Nowadays, we can see that the implementation of smart system
technology in building is very convenient for human beings. With a
smart device and Internet connected, we are able to have smart
system services such as fire protection, security system,
telecommunication, mechanical handling, and also air conditioning
and ventilation systems. All these systems can function smartly via
the control of remote devices or robust internet.

By installing the smart system in the building, it can ease and facilitate
human works and problems. Other than that, it also may improve
energy efficiency, make us comfortable and can directly save more
times which what we need these days. All in all, the efficiency of the
smart building can benefit the user in a long term as it gives many
positive impacts on the life of our society.

Other than that, the rapid development of robotics and electrical that
was invented by the human, leads to the multi creation of smart
equipment that can provide more safety and convenience to the
building’s user. Thus, it is proven that a smart system technology for
building is necessity for the society in way to move intelligently
towards a more modern and developing country in the future ahead.
