What is an HVAC system, how it works, its importance and advantages!

Air conditioning is essential to ensure the thermal comfort of employees, preserving quality of products/services and production. Thus, you, as the person responsible for monitoring the equipment, must understand how an HVAC system works.

Just so that there is no doubt, we have prepared a complete article in which we will explain all the points related to the air conditioning system. Do you know what each acronym means and the advantages of investing in this resource?

Keep reading and find out what the HVAC system is and the differentials it offers to the company.

Have a nice read!

What is an HVAC system?

The expansion of the acronym HVAC represents three central and primordial functions of the air conditioning system: Heating, Ventilation and Air Conditioning, which together provides:

• Thermal comfort for everyone in the environment, such as employees, managers and outsourced workers;
• Guarantee of high quality of the air that circulates through the company;
• Control over some air-related variables.

To help you better understand what the HVAC system is, let's explain the acronyms separately, check out:

Heating

It is the function responsible for heating the environment, i.e. it ensures that the air temperature remains stable. This happens through a correction of low temperatures, providing comfort to those allocated in the place.

It is also usually used during the process of maintaining air humidity, making its reheat.

Ventilation

Its role is to ensure oxygen renewal while air circulates freely through the rooms. Thus, impurities and strong odors that accumulate due to the operation of the machines are removed.

Sentilation is a great contributor to prevent gasses such as CO² from having a high concentration in the environment.

Air Conditioning

The air conditioning system is responsible for the ventilation and cooling of the environment and its where the air filters are installed. These filters eliminate impurities from the air that can be harmful to health.

Refrigeration

Although its acronym is not often used, the HVAC-R system is the most efficient available on the market. Refrigeration takes care of controlling the heat of the environment and keeping the temperature low, resulting in artificial cooling.

It's worth remembering that this is also one of the functions that make up the air conditioning. This system is widely used in the food industry and refrigerators, as these are places that require lower temperatures.

How does an HVAC system work?

As you may have noticed, the HVAC system ensures efficient temperature control. It can only perform this function by combining all the elements that make up the acronym.

In this way, we can point out the functionality of the HVAC system:

• Air renewal: Ventilation helps with air circulation, improving the oxygen available in the environment. It also helps with removing carbon dioxide, which is highly harmful to health and can cause overheating of equipment;
• Reduces contamination: a well-ventilated environment with the ideal temperature also reduces the incidence of fungi, bacteria, viruses and other disease-causing agents;
• Promotes thermal comfort: Employee productivity is higher when they are comfortable in the work environment. Therefore, HVAC systems provide the removal of excess heat generated by machines and other equipment in the production process;
• Air humidity control: In the same way keeping track of the temperature is crucial, controlling humidity of the indoor environment is also important to prevent equipment wear and the proliferation of bacteria and viruses;
• Reduces particles: air filtration eliminates particles that can trigger respiratory diseases and other illnesses. In order to function correctly, maintenance needs to be regular, along with tracking energy consumption.

Advantages of the HVAC system for companies

Having understood what the HVAC system is and how it works, it's time to learn more about the advantages. Here are four benefits that a company can achieve by investing in this system:

• Efficient air filtration;
• Increased oxygenation of the environment;
• The most suitable temperature for the environment;
• Indoor humidity control.

Efficient air filtration

Air filters are components of air conditioning and act as agents that eliminate dust particles, fungi and bacteria. In result, the environment becomes free of most impurities present, providing well-being to people's health.

The preventive maintenance done in the entire HVAC system must consider, mainly, filter change. Only then will it continue to perform its function efficiently and will not trigger excessive energy consumption.

Increased oxygenation of the environment

This advantage is a consequence of efficient air filtration, as it reduces the amount of pollutants in the environment. This way, oxygenation ends up increasing, effectively contributing to the conservation of the place and the reduction of allergic and respiratory diseases.

The most suitable temperature for the environment

The ambient temperature has a direct impact on several company activities, from team productivity to machine operation. Keeping it at the proper level contributes to all activities being carried out efficiently.

Professionals who work in excessive heat or cold are not as productive as these conditions can trigger stress, anxiety and restlessness.

Indoor humidity control

Indoor humidity control is also one of the features of the HVAC system. There is a limit that must be maintained in relation to this factor and with HVAC system automation, the process becomes easier.

The use of sensors in the environment allows actions to be taken whenever the limit is exceeded. With the help of IoT and other technologies, some companies have started to develop intelligent control.

An example is Squair, a startup with efficient solutions, which guarantee the company's environmental responsibility. Our devices have the ability to transform HVAC systems to automate them and make them more efficient.

In addition to having climate control monitoring, you will be able to predict failures based on operating history. Learn more about Squair and how it can help you secure the advantages of the HVAC system.
