On account of the large
complexity of heating, ventilation and air conditioning, HVAC systems require a
wide range of specific knowledge on each of these domains in order to do a
high-quality service installing them as a whole. Such expertise needs not only
a great initial education but also – and perhaps more importantly – a constant
learning process over the course of the career, a (more than) positive attitude
achievable by “just” following the latest advances and constantly seeking to
improve the skills to reach the next level.
In order to fully utilize
the numerous benefits of those kinds of systems to indoor and automotive
ambience comfort the professional must have previous training and experience in
technical areas underlying the main fields, including thermodynamics,
mechanical engineering and fluid mechanics. While expert comprehension of these
fields is not necessary it is absolutely mandatory to know everything about
heating, ventilation and air conditioning, otherwise there is an elevated probability
of facing an unsolvable problem due to lack of knowledge.
Heating
The first rudimentary
heating systems were mainly water based but nowadays more efficient options are
replacing what was once popular. One of the most established techniques is the use
of forced air systems, which can save up to 150% counting the over-all thrift
with water, energy and efficiency gains, crucial qualities when choosing an
HVAC system.
According to some studies,
forced air systems consume 20% less energy while doubling the performance of
traditional water heating systems, providing an even conditioning and better
air circulation. In the end, forced air systems improve the best of its
predecessor adding the most recent know-how to raise the bar in terms of
cost/benefit, values that most definitely have to be considered for a budget
conscious decision.
The only inconvenience of
forced air systems is the installation cost, since it is considerably higher
than conventional heating systems. Although the final bill could vary from a
contractor to another the differences will be negligible and these types of set
ups will invariably be a few thousand dollars more expensive. However, the
total savings over the course of the years will turn this option into the best
choice for a lifetime HVAC system.
Ventilation
One of the most vital parts
of an HVAC system is the ventilation process, a key feature to any building
construction. Develop a good air circulation structure is fundamental to
increase the life cycle of a closed space, therefore, it must be conceived with
attention to detail and every aspect, from the operation to the way it blends
into the surroundings, deserves careful thought, otherwise it will end up being
just another cluster of devices.
The main function of a
ventilation system consists in filtering the air to remove undesirable agents
whether they are produced indoors or come from outdoor. This task is achieved
by the actions of appliances that can be mechanical, natural or a mixture of
the two, with the actual solution being selected depending on the budget,
necessities and the space characteristics.
When properly installed a
ventilation system will drastically enhance the air quality thus reducing the
likelihood of certain diseases extremely common on people who usually spend
hours in confined spaces not correctly ventilated. Many of those health hazards
can easily be avoided by a budget-friendly elementary ventilation installation
that will pay itself in less than a year.
Air conditioning
No perfect HVAC system
would be completed without the air conditioning elements, hence, understanding
how they work, and its advantages is imperative, namely perceive its role in
the HVAC system, a deep knowledge that must exist concerning both heating and ventilation
part as well.
Regarding the air
conditioning a key rule is maintaining the equipment clean to prevent any sort
of respiratory problems caused because of impediments generated by a poorly
preserved system. Consequently, a professional working with air conditioning
must advise the person in charge of the arranged space of the fundamental fact
that it will need regular maintenance to keep functioning in the most efficient
way possible throughout the years.
A technician should be
prepared to solve issues such as lost of performance, noise or wasted energy,
three of the most frequent situations that affect air conditioning
installations. Even after being repeatedly used without problems, a simple
alteration can trigger an unusual response from the system, for which the
professional has to provide an adequate response.
