Understanding HVAC Systems: Operation and Types
HVAC has recently become one of the most curious ventilation systems in Turkey. As the high-rise, small-window house styles of modern construction spread, the interest in the HVAC system seems to increase even more. So what is HVAC? Is it suitable for every home and every workplace? What is its difference from air conditioning? How does it work? What are the types of HVAC systems? The answers to all your questions and more are in the rest of the article.
What is HVAC? What does it mean?
Heating, Ventilating, Air Conditioning (HVAC) stands for heating, ventilation and air conditioning. By combining the initials of these words, the term HVAC is used as a sectoral abbreviation. HVAC refers to air systems used to heat and cool both residences and businesses, as well as to provide air flow between indoor and outdoor space. HVAC keeps you warm in winter and provides coolness and refreshment in summer. It also keeps the indoor air balanced with its filtering and cleaning system to provide a healthy environment and keep the humidity level at the best level.
How does HVAC work?
There are situations where HVAC components can operate independently of each other. But what is more common is that each component works together with the others. These so-called “combined systems” include both central heating and air conditioning systems. The purpose of an HVAC system is more than just heating or cooling the space.
It serves to improve indoor air quality at an optimum level and provide the same environment for everyone in the apartment. Although HVAC systems have different types of systems (which we will cover below), all systems operate on the same principles.
The role of this ventilation system is to regulate and improve indoor air quality
The process of mechanical ventilation removes stale, dirty air from a home or building and replaces it with fresh air. Installing or upgrading an HVAC system to provide mechanical ventilation throughout a building can provide a variety of health benefits.
use the HVAC system regularly; It may help relieve symptoms for those who are sensitive to airborne particles in general, especially those with asthma. By running one of these systems 24 hours a day, air quality in homes can be significantly improved and even provide a better night's sleep.
HVAC principle: A mechanical system that moves air in and out
First, there is a source of fresh air intake from outside or from inside the house. Natural ventilation is available in most homes and refers to the way air moves in and out, typically through windows, doors, vents, and other openings. This air exchange is necessary to replenish oxygen and remove odors, carbon dioxide and excess moisture. Mechanical ventilation uses a mechanical system to move air in and out.
Houses with windows that are getting smaller with modern construction need an HVAC system
In the past, most homes had plenty of natural ventilation through gaps and cracks in the construction, along with opening and closing doors. HVAC systems are becoming popular in new construction as modern construction focuses on smaller windows and boxier homes than older homes. Therefore, ventilation is becoming an increasingly important component in homes. Once the air is brought in, it is drawn into an air handling unit where the work begins. Here, air is drawn through filters to remove dirt, dust, allergens and other particles.
The system uses fresh air from the outdoor environment to provide high indoor air quality.
V in HVAC or ventilation is the process of changing or changing the air within a space. The system uses fresh air from the outdoor environment to provide high indoor air quality. This provides a better quality of air indoors and includes the removal of moisture, smoke, odors, heat, dust, airborne bacteria, carbon dioxide and other gases, as well as temperature control and oxygen supplementation.
Air is either sent to be heated or to be cooled and remove excess moisture. Air is directed into the home when it is clean, fresh and at a comfortable temperature. For centralized systems, this means moving from a network of channels and recording to different rooms. For other systems, this usually means routing directly to the field.
What does an HVAC system include?
A basic HVAC system consists of a heating unit, a cooling unit, and ductwork to move heated or cooled air. Generally, a furnace serves as the heating unit. Whether the furnace operates on natural gas or electricity, its efficiency is the Annual Fuel Usage Efficiency (which shows how much fuel is converted into heat).AFUE) is measured in degrees. A furnace with an AFUE rating of 95% converts 95% of the fuel supplied to it into heat. Today, the minimum acceptable AFUE rating is 80%.
So what are the types of this system?
Each system varies depending on a home's heating and cooling needs, its location, its age, existing ductwork, heating and cooling needs, and other factors.
Partition system: A split system, also called a forced air system, has one unit inside and outside the home. This installation may consist of a furnace and air conditioner, an air handler and heat pump, or a furnace and heat pump. Which configuration is best for your home will largely depend on where you live. For example, a furnace and heat pump installation works best in very cold climates.
Hybrid heat pump: In this scenario, the central heating system includes an electric heat pump working in conjunction with a furnace. During milder times of the year, such as spring and autumn, the heat pump heats the home. In weather that is too cold for a heat pump to work effectively, the furnace kicks in. Also known as a dual-fuel system, this hybrid system saves money because it costs less to heat the home with a heat pump than with a furnace.
Ductless mini split: This type of ductless system is generally best for small spaces that do not require a traditional split system, such as garages and workshops. They are not suitable for all home applications. Typically, these systems are easy enough for the homeowner to install themselves.
Channeled mini split: A ducted mini-split system uses tubes instead of larger ducts to move air from an outside compressor and condenser into a room. This solution is best for homes that don't have much room for traditional ducts. Compared to ductless mini split systems, ducted mini splits have the advantage of better air circulation.
Package system: A packaged system includes the traditional components of a split system. However, all units are located outside. This solution works best in homes that do not have space for a heating unit inside the home. Even if you have the space for a split system, you may want to consider a packaged system because they are quieter (everything is located outside the house) and have lower installation costs (there is only one unit to install).
What is the difference between HVAC and air conditioning?
This may be the question most wondered by those doing research on the HVAC system. So, what exactly is the difference between HVAC and air conditioning? This ventilation system and air conditioning are often used interchangeably. However, the terms actually mean two different things. When an HVAC system consists of several components that work together to regulate temperature and ventilation in a building, air conditioners simply cool that building.
Think of it this way: While an HVAC system may include a furnace, ductwork, air purifier, smart thermostat, and air conditioner, a central air conditioner is just an air conditioner. In other words, an air conditioner may fall under the HVAC umbrella, but not all HVAC systems actually include an air conditioner.
