Before discussing various types of HVAC systems for commercial buildings, here is a short overview of what HVAC systems are and what they can do.
HVAC stands for heating, ventilation, and air conditioning. The primary job of the HVAC system is to keep the temperature of the building cool in the summer and warm in the winter. The ventilation system keeps the air clean by passing it through filters.
HVAC systems are used in industrial, commercial, institutional, and residential buildings.
Make sure to read the article thoroughly because, at the end of this guide, you will learn the five things you must know before installing a commercial HVAC system and top tips to increase the lifespan of a commercial HVAC system.
Main components of HVAC systems
Before moving forward, let’s take a look at the main components of commercial HVAC systems.
The thermostat, air conditioner, compressor, condenser, thermal expansion valve, furnace, duct system, water chiller, air handler, terminal units, and make-up air unit (MAU) are the main components of commercial HVAC systems.
Below, we will discuss different kinds of HVAC systems for commercial buildings to make it easy for you to choose the system that works best for you.
Types of HVAC systems: Commercial
Single Split System
The single split HVAC system is affordable and efficient, which is ideal for smaller commercial buildings. The system has an indoor unit and an outdoor unit linked by copper pipe.
The drawback of this system is that it occupies a lot of space because it has an outdoor unit for each indoor unit. It is cheaper than other HVAC systems and best for small offices, shops, and restaurants.
The Multi-Split System is perfect for larger spaces. In this system, around five to nine indoor units can connect to a single outdoor unit. Because of this, it occupies less space as compared to a single split system.
A Multi-Split System consumes far less energy. It has sensors that detect temperature changes and can adjust as needed, which also saves money.
The cost of the installation of this system is higher than a single split system. This system requires more time to install because of more pipework.
VRF (variable refrigerant flow), also known as VRV (variable refrigerant volume), is an HVAC system ideal for medium and large commercial buildings.
It is similar to a multi-split system because the VRF system also has one condenser for multiple evaporators. There are two types of VRF. One is a heat pump system, which can deliver either heating or cooling.
The second is the heat recovery system, which can provide heating and cooling simultaneously. The VRF system is expensive to install. The whole VRF system will be affected if the unit breaks down.
A constant air volume (CAV) system provides uniform airflow at a variable temperature and is ideal for small commercial zones.
The CAV system is cheaper and easy to install. If you are looking for a more efficient HVAC system for larger spaces, then you can consider the VAV system.
Variable air volume (VAV) is an energy-efficient system and delivers a variable airflow at a constant temperature. VAV has various advantages over the CAV system.
This system can meet the heating and cooling needs of large commercial buildings.
More control of humidity and temperature, reduced compressor wear, lower energy consumption, and less fan noise are advantages of the VAV over the CAV system. However, this system is expensive to install. Further, the installation of this system requires a lot of space inside the building.
Top tips to increase the lifespan of commercial HVAC System
Various factors can severely affect the lifespan of HVAC systems. For example, poor maintenance, low quality or defective components, and poor installation of the system. To learn more about proper HVAC installation, visit https://cloverco.com/hvac/ac-installation/.
Below, we mention some tips that can help maintain efficiency and extend the lifespan of the HVAC system.
- Quality installation and regular maintenance from licensed professionals can increase the lifespan of your HVAC system.
- The filter is the essential component of the system that keeps dirt, dust, pet dander, and other debris from entering the system.
When the filter gets overloaded with dirt, then it can’t work efficiently. Change the air filter once a month to avoid this problem.
- Make sure to clean up the ducts of your HVAC system every 2 to 5 years because ducts are passages through which cooled and heated air passes.
- Always keep the area surrounding of HVAC system clean. For maximum performance, the system needs adequate airflow.
- Also, make sure the outdoor components of the system are clean of grass, leaves, and any kinds of waste material.
Five things you must know before installing the commercial HVAC system
HVAC systems are becoming more efficient and advanced as technology evolves. Below, we mention some things you should know before installing a commercial HVAC system.
- Know about the latest cooling and heating technologies used in HVAC commercial systems from your potential contractors or another source if possible.
- It’s necessary to figure out the most suitable HVAC system that can meet your needs. To figure it out, organize a meeting with your contractor.
- Before installing an HVAC system, make it clear the exact cost of the system and installation. Also, set a max amount because ductwork, piping, and other installation work can add a lot to the installation cost.
- Installing a system can be costly, but not taking proper care of it can be more expensive. Talk to your contractor and tell him to include regular maintenance of the system in the contract.
- Get a guarantee of the system parts and professionals who will install the system to ensure your HVAC system will work efficiently.
How long do HVAC systems last?
The tips mentioned above play a crucial role in the life span of your HVAC system. However, the average lifespan of commercial HVAC systems is around 15 years. But by following the above tips, your HVAC system can last well over 15 years.
