The Benefits of a Rooftop HVAC Unit

An HVAC, which stands for heating, ventilation, and air conditioning, is the technology of an indoor, automotive environmental comfort.   HVACs are designed using the principles of fluid mechanics, thermodynamics, and heat transfer.

Heating

There are many different kinds of heating units.  A central heating unit is beneficial in cold areas, and they are used to heat a home or office.  They transfer heat through ductwork, piping, or a radiator to transfer or force hot air into a room.  Some buildings will use furnaces or boilers for indoor heating.  Proper ventilation needs to be in place for this equipment to safeguard from carbon monoxide.  Carbon monoxide occurs when there is insufficient oxygen in the air.  A heating unit can use many different technologies.  Fossil fuels are typically used such as oil or propane in a furnace or boiler.

Ventilation

Ventilation is the changing or the replacing of air into a room to control the temperature and remove anything unsafe that is in the room.  This process not only ventilates the air inside to the outside, it also circulates the air within the building.  Proper ventilation ensures that the building has quality air.  Otherwise a building may get mold, mildew, or odors.  Plus airborne viruses or diseases will be harder to control without ventilation.  To control the ventilation unit is connected to the ductwork.

Air Conditioning

Air conditioners do the opposite of heaters.  They are used to cool off a room or building.  An AC unit provides cooling, ventilation, and humidity control by using mechanical refrigeration.  They may use water, ice, or air as a refrigerant.  Some modern units will use a chemical refrigerant.  The refrigerant starts in a gaseous state where a compressor causes the gas to build up high pressures and temperature.  The gas is then released into a condensing where the heat dissipates in outside air where it becomes a liquid.  After the liquid evaporates it goes back to a gas.  This process draws in heat from the surrounding air.

HVAC

Many commercial buildings require an HVAC system to maintain the temperature and air quality.  Commercial buildings that have a flat roof need special equipment to install the HVAC.  A rooftop HVAC is installed using HVAC roof supports.  HVAC supports keep the HVAC unit from penetrating or damaging the roof.  They support the weight of the unit so that the HVAC does not create a hole in the roof and also makes sure that rain, snow, and hail do not pool around the HVAC unit.

PHP Systems/Designs is the leader for roof HVAC duct support systems.  At PHP, we engineer rooftop HVAC supports and duct support systems with code-compliant designs.
