Retail stores and small industrial buildings often include rooftop HVAC units, that are used to distribute air conditioning to designated regions. These are package air conditioning systems, and they are common because they are simple, small, self-contained all-in-one HVAC units. It distributes cool air within a stipulated area of the building. The ductwork that connects rooftop HVAC units provides a defined path for the conditioned air to flow.
RTUs are different from split units. Split units are placed separately indoors and outdoors. The furnace or air handle is installed indoors, and the air conditioner or heat pump is set up outside.
It is easy to get a rooftop HVAC unit installed at your residential, industrial, or commercial building with the help of Con-Form Group. It is an Australian-based company that sells a metal platform for rooftop HVAC units, rooftop gardens, rooftop workspace, and equipment rooms. Their knowledgeable staff of internal engineers and designers, who specialise in mounting mechanical platform, provides advice on the specifications for your mechanical equipment mounting project.
The function of Rooftop HVAC Units
Rooftop HVAC units perform similarly to other types of heating and cooling equipment, giving residents affordable comfort. These systems are attached to the ductwork of the structure and circulate heated or cooled air throughout the interior space.
Heat Out
Once a rooftop air conditioner is installed, the cool, low-pressure refrigerant enters the compressor as gas and, upon entering the condenser coil, condenses into a hot, high-pressure gas. The condenser fan blows the exhaust away from the building as a result of the metal fins on the coil that absorb and disperse the heat.
Fresh air enters the rooftop unit for ventilation while warm return air enters through the ducts. Air filters are positioned over the return air duct to stop pollutants from touching the delicate cooling equipment.
Cooling Cycle
- When heat is released from the refrigerant, it passes through the evaporator coil.
- The refrigerant turns into a liquid when the pressure is reduced.
- The refrigerant absorbs heat from the heated air in the building while it is still in liquid form and spreading through the could.
- The evaporator fan circulates cooler air to the rooms in the building after the refrigerant has removed the heat from the air by sucking it up.
- The refrigerant is now heated and transitions to gas form. In this condition, it returns to the compressor to release and expel the heat.
- This process continues until the outside temperature of the building matches the internal temperature set by the thermostat and other controls.
Benefits of RTUs
- Since all HVAC units are installed on top of the building, a rooftop unit frees up space that would otherwise be taken up by indoor equipment if a split system were being used.
- Upside HVAC units are protected against theft and sabotage because of where they are installed.
- Since all units are located outside the building, there is less interior noise when the system is operating than there would be with a split system.
- Rooftop HVAC units are easier for technicians to access because all elements are stored together. With all the parts in one place, maintenance and repairs are done more quickly.
Rooftop HVAC units are easy to install, access, and maintain. When buying from a reputable dealer you also get installation and warranty for free. Choose a high-quality rooftop unit for a long-lasting result.
