With the North Texas region being subject to various temperature extremes during a
calendar year, ranging from high winds to hail to single-digit
temperatures to weather above 100 degrees and humid, heating
and cooling technicians have to be ready to handle a wide array of
problems not commonly found in other areas of the country.
This requires a HVAC professional to understand virtually
everything that a heating and cooling professional can learn - with the
exception of sub-zero conditions!
This resource from Maryland wrote
a comprehensive guide to the basics of commercial HVAC. Here
are some points from that article:
A commercial HVAC
(heating, ventilation and air conditioning) System has the same
objective as a residential HVAC system - to keep the building occupants
cozy with high quality air in a 72-degree environment, the humidity
ranging from 40 to 60 percent.
The heating of air is
often achieved through burning fuel (gas, oil, electricity). Cooling
the air is the opposite (naturally), with a process that extracts hot
indoor air and cools it through refrigerant or water-cooled systems,
eliminating the extra humidity at the same time.
Controlling the climate
in a commercial building requires three things: warm or cool air, a
distribution method, and controls..
Packaged
systems are all-in-one units, consisting of the compressor, condenser,
evaporator, and fan coil. The thermostat is integrated. Packaged HVAC
units are great for buildings that don’t have the room for bigger ones.
