The full form of HVAC is heating, ventilation, and air conditioning. It is used for heating and cooling purposes in both commercial and residential buildings.

HVAC systems can be seen anywhere including single-family homes to ships where they offer environmental comfort. These systems are garnering popularity in new construction, as they utilize fresh air from the outside environment and improve indoor air quality.

The V in HVAC stands for ventilation. It is the process that involves the exchange or replacement the air within a space. It enhances indoor air quality by removing smoke, moisture, heat, odors, dust, carbon dioxide, airborne bacteria, and other gases, including oxygen replenishment and temperature control.

The major functions of an HVAC system are interrelated, more specifically it provides acceptable indoor air quality and thermal comfort. The air conditioning and heating system are usually used in the complicated and extensive systems of the home. There are primarily nine parts of the HVAC system, including filter, air return, ducts, exhaust outlets, outdoor unit, electrical elements, blower, compressor, and coils.

Major Parts of the HVAC Systems

Air Return: The air return sucks the air in, draws it through the filter, and transfers it to the main systems. The returns should be dusted frequently to prevent them from building up on the filter.

Filter: The filter is the second essential part of the air return in which the air is drawn. You must change the filters regularly to keep the system functioning properly.

Exhaust Outlets: Exhaust outlets are other essential parts of the system, that creates exhaust by expelling the heating system.

Ducts: Ducts are the channels through which the heated or cooled air is passed. You must get your ducts cleaned every 2 to 5 years to keep them working properly.

Electrical Elements: If something is not working properly, then the thermostat should be checked for a tripped breaker or dead batteries.

Outdoor Unit: It is that part that is visualized when HVAC is mentioned. The outdoor unit consists of a fan that facilitates airflow.

Compressor: The compressor converts the refrigerant from a gas to liquid, and sends it to the coils. If something is not working properly, then the compressor should be checked.

Coils: It is the major part of the outdoor unit, responsible for cooling the air passed from the refrigerant.

The expansion of the construction sector in the Middle East and Africa region is projected to propel the demand for HVAC systems. The rising demand for VRF systems in the high-rise buildings in the MEA region and low-cost benefits is projected to result in the massive adoption of HVAC systems.

The major players operating in the industry are; United Technologies Corporation, Mitsubishi Electric Corporation, Toshiba Carrier Corporation, Ingersoll-Rand plc, Midea Group Co. Ltd., LG Electronics Inc., and Fujitsu Limited.

Therefore, the expansion of the construction sector in the MEA region results in rising demand for HVAC systems.
