COMMERCIAL HVAC
SINGLE-SPLIT SYSTEMS​
​
Single split systems are the most affordable type of HVAC system and are suitable for small commercial building use. They heat and cool individual rooms — making them ideal for shops, server rooms, cafés, and small offices.
​
You can also use them in combinations to serve larger areas or multiple rooms. The only negative is that there needs to be enough external space to install a corresponding outdoor unit for each indoor unit.
​
The advantages of this system include:
-
It is less expensive than installing a central system.
-
Each system is self-contained, so if one unit breaks down, it won’t affect the others.
-
As your business expands, you can add cooling capacity in a one-to-one ratio.
Even though this is a less expensive system, it is very versatile, effective, and energy-efficient.
MULTI-SPLIT AIR CONDITIONING​
​
Earth excavation is removal of the layer of soil immediately under the topsoil and on top of rock. Used to construct embankments and foundations, earth usually is easy to move with scrapers or other types of earthmoving equipment. Rock excavation is removal of a formation that cannot be excavated without drilling and blasting. Any boulder larger than 1⁄2 yd3 generally is classified as rock. In contrast, earth is a formation that when plowed and ripped breaks down into small enough pieces to be easily moved, loaded in hauling units, and readily incorporated into an embankment or foundation in relatively thin layers. Rock, when deposited in an embankment, is placed in thick layers, usually exceeding 18 in.
VRF AND VRV​
​
Variable refrigerant flow (VRF) and variable refrigerant volume (VRV) refer to the same type of commercial HVAC system. The two terms are used interchangeably. This is a great HVAC solution for medium to large applications such as hotels, larger offices, or retail spaces.
​
VRF and VRV systems use heat pumps and heat recovery. Heat pump systems provide heating or cooling to a building at any time, which is ideal for open plan spaces. Heat recovery systems are able to provide simultaneous heating and cooling to a number of areas at the same, making it a suitable solution for a building with different rooms. Efficient commercial HVAC systems recover waste heat from around the building and use it to heat water and other rooms. The heat recovery system is flexible as you can cool one room while heating another.
​
HVAC AND WAREHOUSES​
​
Combining HVAC systems with other ventilation options is a good idea in a warehouse. Big ceiling fans set on high volume/low speed can help to cut the temperature in your warehouse substantially. The combination of an industrial portable box fan with a refined misting system provides cool comfort economically.
ROOFTOP UNITS​
​
A rooftop HVAC unit, or RTU, works very similarly to most indoor systems: They provide heating or cooling to an area by treating the air that passes through it and then circulating that air.
​
In particular, a rooftop unit is an air handler – the part of the system that conditions the air and circulates it. From there, the air typically travels through ductwork and vents to the space you’re treating.
​
What’s specific about rooftop air handlers versus indoor ones is their location. And, they’re designed a little differently to account for their being outdoors.
​
RTU’s are more robust and weather-proof. They’re made to prevent rain, snow, debris, and even animals from getting in, while still allowing air to pass through.
​
HEATERS​
​
-
Heaters: The two types of heaters are radiant heaters for direct heat, or hot air furnaces that heat air by burning fuel.
​
-
Heat pumps: Heat is extracted from water or air for heating. With a water source heat pump, water runs through a pipe to supply the heat pump.
CHILLERS​
​
Cool water is generated and distributed to air cooling coils via a pipe. Industrial water chillers provide an immediate reduction in water use and consistent water temperatures, which in turn offer significant improvement to the process and a quick return on investment.
