A comfortable climate in the rooms where we spend most of our lives can go a long way to improve performance and mood. No one will argue that it is much more pleasant to be in a room with fresh air than in a stuffy, hot, or excessively chilly room. Therefore, the popularity of heating, ventilation and air conditioning (HVAC) systems is only growing. Today we will tell you more about the HVAC air conditioning system.
What is an HVAC system?
HVAC is heating, ventilation, and air conditioning. HVAC refers to systems that are used to move air between indoor and outdoor spaces. Also, this system can be used for heating and cooling rooms of any type. These air conditioning systems can also filter and purify indoor air to keep you healthy and keep humidity levels at an optimal level. According to the American Society of Heating, Refrigeration and Air Conditioning Engineers, at its most basic level, an HVAC and AC (air conditioning) system sucks in air, cools or heats that air, and blows it into a room. All air conditioners take hot air and replace it with cold air.

Working principle of HVAC system
To cool the air, a fan in an HVAC air conditioner draws in air and forces it onto the evaporator coils. These coils are then filled with refrigerant, which extracts heat from the air. The cooled air then enters the ventilation system, where the blower directs it into the ducts. As cold air moves through the ducts, any harmful gases produced during the process are expelled through the chimney. This ensures better indoor air quality and includes removing moisture, smoke, odors, heat, dust, airborne bacteria, carbon dioxide and other gases.
How does the air in an HVAC system get the right temperature? Air passes over the heating element, so that the air temperature corresponds to the desired temperature, which can be adjusted in the HVAC system settings. The refrigerant inside the pipes is heated during the process, which turns it into a gas. The fan then pushes the heat out, thereby cooling the liquid.
What does an HVAC system include?
The simplest HVAC system consists of a heating unit, a cooling unit, and a duct to move the heated or cooled air. The furnace can run on natural gas, electricity or propane. The efficiency of the furnace that serves as the heating element is measured by Annualized Fuel Usage Efficiency (AFUE). This indicates the amount of fuel that is converted into heat. A furnace with an AFUE rating of 95% converts 95% of the fuel supplied into heat. To date, the minimum AFUE rating is 80%.
What are the types of HVAC systems?
There are four main types of HVAC system. As a rule, air conditioning systems are purchased based on the size of the premises and your needs. But let’s look at the four types of HVAC:
- Split system. In this system, the HVAC unit is located between the two main units – cooling and heating. This system is one of the most popular systems in American families.
- Heat Pump system. A hybrid AC system can be considered an advanced version of a split system. This system has an electric heater which improves energy efficiency.
- Ductless Minisplit system. This system is suitable for buildings that do not have a standard duct system. Most often, the system consists of an external air conditioner and a heat pump.
- Central Air Conditioning (CAC) system. The distinguishing feature of this system is the ability to heat and cool the air in one unit. As a rule, a complete HVAC system is installed outside, which is why it is so often used in houses without a basement.
