What is HVAC: How Does it Work?

 Introduction:

To begin with, HVAC stands for Heating, Ventilation, and Air Conditioning. It is a system that moves air between indoor and outdoor areas and heats and cools it for residential and commercial buildings. This system also filters and cleans indoor air to keep you healthy and maintain humidity levels. To further know about it, one can visit HVAC Online Training in Oman.

Components of HVAC:

Given below are some of the most important components of an HVAC System.

• The design and type of ductwork- The ducts should be of proper size and balance to ensure comfort at home. Externally insulated round ducts are best for this job.
• Balance dampers in the ductwork- Balance dampers help in managing heating and cooling coming into a room. They should be installed at some distance from the diffusers.
• Location of the Indoor Unit- It is very necessary to take special design precautions while locating the indoor units. Locating them in the wrong place can cause leaks and ceiling damage.
• Location of the Outdoor Unit- Outdoor units should not be placed in places where they can be seen and heard, or where they can be easily damaged.
• Efficiency- The minimum allowable efficiency for new air conditioners should be 13-SEER. In addition, the higher the SEER, the lower the utility bill.
• The condenser (outside) coil type- It is beneficial to use coils that are made of a single metal. These coils last longer and hold their efficiency better.
• Air Filter Location- Place this device in a place where it is easy for the homeowner to reach. It is because these filters need to be replaced about every three to four months.

How Does HVAC System Work?

Apart from just warming up or cooling the space, HVAC also helps in improving indoor air quality and providing comfort. It all starts with a source of fresh air intake from the outside or from within the home. This process is known as natural ventilation and it facilitates the exchange of air to replenish oxygen and remove odors, carbon dioxide, and excessive moisture. Many institutes provide HVAC Online Certification in Qatar and one can enroll in them to understand its working.

V in HVAC stands for Machinal ventilation and it refers to moving air in and out. Modern construction is creating homes that are far more tightly sealed. Therefore, mechanical ventilation is becoming an increasingly important component in home HVAC systems. After drawing in the air, it goes through an air handling unit where the work begins. Here the dirt, dust, allergens, and other particles are removed from the air. After that, the air goes for either heating or cooling. Once the air is clean, fresh, and at a comfortable temperature, it directly goes toward homes.
