The 3 main commercial hvac systems and how they work

-

Heating, Ventilation, and Cooling systems, otherwise known as HVAC systems, are a vital part of any modern commercial building. The job of an HVAC system is to keep temperatures comfortable (usually around 72 degrees), humidity consistent (between 40-60%), and indoor air quality high.
There are many different types of commercial HVAC systems; however, in general, these systems operate the same:

An AC unit lowers the temperature by passing air through refrigerant or water-cooled systems, removing excess moisture from the air in the process. Heating systems work exactly  the opposite; air passes through systems that heat the air using water, radiator coils, or gas.
Ventilation systems keep the air clean by circulating air with fans and passing air through filtration systems.

The Different Types Of HVAC Systems


If you’ve considered replacing your buildings’ HVAC system, you’ll know that there are an overwhelming number of combinations of different types of systems. While this is true, all of these various types fall into three main categories:

  • The Single Split System
This system is the most affordable of HVAC system. Are commonly used in smaller commercial buildings and residences. This system allows for individual control of each space. The system includes air conditioners that pass air by refrigerant coils above a furnace or  in an air handler. One system  circulates the air via ducts. The disadvantage of a single split system is that for each space controlled separately, you’ll need an outdoor unit.

  • The Multi- Mini Split System
Multi- mini split systems operate likewise to a single split system, but is much more energy-efficient and has a much smaller outdoor footprint. Multi-split systems allow you to connect up to 9 indoor units to one outdoor unit. The system also includes heat sensors that detect temperature changes, adjust as needed, and consume far less energy. 

Furthermore, the heat pump in this system is designed to move air in a way that works with the natural flow of warm air into cool areas, saving money and energy. The disadvantage of these systems is that they require more installation time, 

  • The VRF (variable refrigerant flow) or VRV (variable refrigerant volume) System
These systems are preferred for larger mixed-use type buildings, such as office buildings or hotels. VRF systems can provide heating and cooling to different areas at once, using warm air from areas of the building and delivering it to where heat is required. This is especially beneficial for buildings with lots of smaller rooms. Heat pump VRF systems provide either heat or cooling and are best for larger open areas

A proper heating system is essential for every commercial building, including factories and industrial sites, and having the correct  boiler system installed  and maintained by specialists is key to operational efficiency and minimal downtime.

A good commercial HVAC contractor is more than a company that you call when things start going wrong in your building – they’re a partner who works with you to ensure a healthy, comfortable environment for employees, clients and tenants.

Don’t Make These Mistakes When Hiring a Commercial Contractor  You don’t know what you need:  Of course, your HVAC contractor should be able to do a full assessment of your system and advise you on repairs or upgrades, but it’s important that you have an informed idea of the services you are seeking. Are you making energy-efficiency a priority? Is your system making strange noises and emitting unpleasant smells? What is your budget?
