The Purpose of Having HVACs in Buildings and Other Enclosed Places

HVAC is an abbreviation of heating, ventilation, and air conditioning. As the name goes, HVACs are technologically developed units that are designed to provide indoor heating, ventilation, and air conditioning. Life is all about comfort, but there can never be comfort in the absence of quality air and favorable thermal conditions. For this reason, HVAC units are installed in residential and commercial buildings for comfort purposes and to reduce chances of suffocation. It’s also common to find them installed in hospitals, churches, halls, hotels, buses, and other social places to regulate the temperature and to ensure free circulation of air.

HVACs are subject to tear and wear, and it is, therefore, necessary to repair them on a regular basis, failure to which the air quality in a room is compromised. In case you have a problem of forgetting to repair your HVAC, Clear Air Club is there for you. Visit timely delivery of air filters every time your HVAC need repair.

HVACs perform three distinct functions, but which are interrelated. Heating is necessary for a moderate thermal condition, but it may not provide the desired comfort without a steady and continuous flow of fresh air- fresh air. With proper heating and ventilation, indoor air quality is guaranteed. It is necessary that we delve deeper and understand the exact meaning and purpose of the three functions, each at a time.

Heating System

This basic mechanical engineering utilizes concepts in thermodynamics and heat transfer. The system involves a central heating unit, such as a boiler or a furnace, which heats the air around it. The heating unit can obtain its heat from an electric supply or from burning fuels that include solid, liquid, and gaseous fuels. Upon heating, the air circulates the room through convection or sometimes through radiation. In the modern heating systems, water is heated in a boiler and then pumped into pipes that are connected all around a room. Heat exchangers are then fitted in the pipes to disseminate heat from the hot water to the room.

Ventilation System

Human beings inhale oxygen gas and exhale the unwanted gasses such as carbon dioxide. To get rid of carbon dioxide and to increase oxygen supply in an enclosed place, ventilators are necessary. The purpose of a ventilator is to draw fresh air from outside into the inside.

Ventilation can be either forced or natural where HVAC ventilations fall under the category of forced ventilation. They are fixed in a building to tap excess humidity and contaminants, and then channel them out of the room. Natural ventilation is the process whereby air gets in and out of a room via an opening.

Air Conditioning System

HVAC air conditioners are mostly fitted in buildings that do not have adequate openings, such as windows. They are fitted with a vent that is designed to draw air from outside into the indoor air circulation system. On top of that, they have refrigerants that provide cooling when the room gets too hot and an evaporator coil that facilitates dehumidification in a room
