How does a rooftop hvac unit work

Rooftop units are what are known as package units in the HVAC industry. A split system has an outdoor cabinet and an indoor cabinet with different sets of components. The outdoor cabinet has a compressor, fan, and a condenser coil; the indoor cabinet has a blower, dampers, air handler, and evaporator coil, and hooks into the ventilation system.

With a rooftop package unit, all the components are housed in one cabinet stored on the top of the building. Both sets of coils, to release and absorb heat, are in the cabinet along with the compressors and the fans. Rooftop units can be configured either as air conditioners, or as heat pump capable of both heating and cooling.

With installation of a humidistat on a rooftop unit, it can also control humidity and permit the ventilation of fresh air into the system; this is a benefit that split systems do not have, and it is a great asset for increasing indoor air quality. Rooftop units come in an enormous array of types and sizes, and you will need to have professionals help you select the right unit or units to install for your business.

The blower fan then pushes the conditioned air down another duct and into the main ventilation system of the facility. Rooftop units may be the basic when it comes to commercial heating and cooling, but servicing them is anything but basic.

Well, what is a rooftop HVAC unit in the first place? Rooftop HVAC units or RTUs are normally stationed on the roof of small commercial buildings to provide heating and air conditioning to certain defined locations of a building. They come as a package and since it comes readily assembled from the factory, they can be easily installed to building ductwork where air travels through. RTUs are used to heat and cool residential and commercial buildings. Compared to an indoor system, RTUs are weather-proof and robust.

This enables them to prevent debris, rain, snow and tiny animals from getting in — but only air passed through it.
