Rooftop HVAC units are a necessary part of any building to keep the air inside cool and dry. They do this by pulling in fresh air from outside, cooling it with a refrigeration system, and then pushing it through the ductwork into your home. This article will explain how a rooftop HVAC unit works.
What is a rooftop HVAC unit?
A rooftop HVAC unit is a rooftop air conditioner or heater that is used to cool/heat the entire building. These units are normally more expensive than split systems, but they offer many benefits. Rooftop units are typically found on top of apartment buildings and other multi-unit structures because they have the ability to cool or heat the entire building. Nobody wants to be stuck in the building with a unit that’s not working, so split systems would be no good.
How does a rooftop unit work?
The units have refrigerant lines, an evaporator coil, and a condenser coil. When the outdoor temperature is low enough, the unit will draw air from outside over the evaporator coil, which draws heat from the air as it passes through. This heat is then transferred to coolant within the unit via a process called compression.
The coolant is then sent to the condenser coil and is released into the air along with some of that heat. The now warm, moist air then passes over the condenser coil where it is cooled and becomes water droplets as a result. The cool air is then pumped back inside, and the refrigerant returns to the compressor to begin another cycle.
Benefits of a rooftop HVAC unit:
– Heats and cools the building for less energy than split systems.
– Rooftop units can be centrally controlled, reducing energy waste even further.
– There is no need to run multiple exhaust pipes from one system.
– The roof provides a clean, easily accessible place to install the unit.
– Rooftop heating and cooling units are compact and lightweight, making them easy to handle and transport.
Who installs rooftop HVAC units?
The installation of rooftop HVAC units is typically done by a contractor. This type of project requires an experienced HVAC professional who can handle the complexities of building a rooftop unit. These units are often much larger than regular HVAC systems, so they need to be installed correctly to ensure proper ventilation and drainage.
Construction of rooftop HVAC units is not an amateur job. If you are working on one of these projects, make sure you hire someone with experience in the industry. There are several contractors who specialize in the installation of rooftop HVAC units in Atlanta.
The rooftop HVAC unit is a great way to keep your home or office cool in the summer. This device sits on top of your roof and blows cold air into an enclosed space, keeping it much cooler than outside temperatures.
