The Basic Elements Of A Commercial HVAC System

You know how essential it is to have a working HVAC system if you're in charge of the heating and cooling in a business facility. But what components make up a commercial HVAC system, and how do they work together to keep your facility comfortable?

In this blog article, we'll look at the main components of a commercial HVAC system and how they operate.
Let's get started.

Outline:

What is Commercial HVAC?

Commercial HVAC systems differ from residential ones in a few ways. Commercial systems, for example, are generally larger and more powerful. They also have a higher capacity to handle large amounts of airflow.

Second, commercial HVAC systems are designed to work with multiple zones. That allows businesses to customize the temperature in different areas of their building.

Finally, commercial systems use components specifically designed for constant use and heavy-duty applications.

The Components of Commercial HVAC

Now that we know what commercial HVAC is, let's look at the components that make it up.

Compressor

The compressor is the most important component of any HVAC system. The refrigerant gas is compressed into a liquid by the compressor. This liquid is then pumped through the rest of the system and turned into cold air.

The compressor is usually located in the outdoor unit of a split system HVAC or the basement of a building with a centralized system.

Condenser

The condenser coil takes the hot refrigerant gas from the indoor unit and converts it into liquid. It then sends this liquid back to the compressor to start the process again.

The condenser is located outside the building, and it's responsible for releasing heat from the refrigerant into the atmosphere. The cooled refrigerant is transferred back into the indoor unit to chill the air.

It's essential to keep the condenser clean, or else it will become clogged with dirt and dust and will not work correctly. You can clean it yourself or have a professional do it for you.

Thermostat

A thermostat has a temperature sensor that tells the device to turn on or off the heater or air conditioner. Thermally controlled rooms may exist, each of which necessitates its thermostat.

The thermostat should be as far away from hot and cold spots as possible to minimize the risk of overheating or freezing.

Heat Generator

The heat generator is a crucial component of HVAC systems when heating. The combustion chamber produces heat in these devices, such as the one depicted above. The heated flue gasses will warm the air or fluid like water, subsequently heating the incoming air. Electric heating may also be used to heat the conditioned air.

Even though there are many heat sources to choose from, the most frequent ones are furnaces; therefore, it's critical to think about combustion efficiency when picking HVAC system components' heat generators.

Heat Exchangers

A heat exchanger is a mechanism that transfers heat from one fluid to another. The coil is the most frequent type of heat exchanger found in HVAC systems. A refrigerant coil is found in a split system's outdoor unit and is responsible for transferring heat from the refrigerant to the air.

The heat is rapidly transferred from the hot air to the cool air to warm a specific space in most circumstances. In this case, a machine blows through hot flue gas tubes or electric heating elements, which absorb the energy and distribute it to the air.

Humidifier

A humidifier is a device that adds moisture to the air. That is important in cold weather because dry air can cause respiratory problems and make you feel uncomfortable.

Most commercial HVAC systems include a built-in humidifier, but you can add one yourself if your system doesn't have one. There are a variety of humidifiers available on the market, so be sure the one you choose will operate with your heating or cooling system.

Air Filter

An air filter is an essential part of any HVAC system. It helps keep the components clean and prevents dust and dirt from building up inside the unit.

It's essential to change the air filter in your HVAC system regularly. Otherwise, it will become clogged and will not work correctly.

Blower

The blower, one of the HVAC system components, forces air through the heat exchanger into the air ducting to take warm air where it is needed. The blower is assisted by an electric motor that drives the shaft. The airflow may be altered by changing the motor speed. Variable-speed motors are required.

The blower is one of the most critical components in an HVAC system because it's responsible for moving air through the unit. If your blower isn't working correctly, you'll notice a decrease in the overall efficiency of your system.

Evaporator Coil

The evaporator coil is hidden within the indoor unit, and it works to cool down the air as it goes through it. The blower then pushes the cooled air out into your facility.

It's essential to keep the evaporator clean, or else it will become clogged with dirt and dust and will not work correctly. You can clean it yourself or have a professional do it for you.

Refrigerant

The refrigerant is what helps cool down the air in the evaporator. It's a liquid that circulates through the system and absorbs heat from the air.

The liquid refrigerant is also responsible for calming down the compressor, which helps keep your HVAC system running efficiently. Be sure to check the refrigerant level in your system regularly and add more if necessary.

Duct System

The duct system transports cooled air to your facility. It's critical to make sure your ducts are properly insulated and sealed, otherwise you'll waste a lot of heat and money.

If your ducts are damaged or leaking, you should repair them as soon as possible. Otherwise, you'll see a decrease in the efficiency of your HVAC system.

Heat Pumps

A heat pump is a machine that converts thermal energy into mechanical movement using refrigerant. It's used in an HVAC system to transfer heat from the outside into your building.

Although heat pumps aren't as popular as other HVAC systems, they can be a viable alternative in cold regions. If you're not sure whether a heat pump is suitable for your company, consult with an expert.

Air Conditioners

An air conditioner is a machine that removes heat from the air and lowers its temperature. It's used to keep your space cool in the summer.

Air conditioners are not as popular as other HVAC systems, but they can be a viable option if you reside in a hot region. If you're unsure whether or not an air conditioner would be appropriate for your company, talk to an expert about it.
