HVAC stands for heating, ventilation and air conditioning. These three systems are closely related and very commonly used in homes and offices. The basic function of HVAC systems is to maintain good air quality indoors by providing proper ventilation and temperature control. These systems are so popular because they are energy efficient and effective.The purpose of a heating system in a HVAC system is to maintain adequate room temperature. In these systems, heating can be of two types- central and local. A heating system is generally made up of a heat pump, a radiator and furnace or a boiler. Each of these has a specific function in the heating system.
Ventilation systems are concerned with air movement. The main purpose of a ventilation system is to ensure that carbon dioxide goes out and oxygen comes in a room so that people can inhale fresh air. If a ventilation system is not installed, stagnant air will cause sickness and allergies. However, a proper ventilation system must be maintained because an inefficient system would result in the growth of bacteria and fungi in a room because of humidity.
The air conditioning system in a HVAC system controls temperature and ventilation both. It generally has large air ducts. So, before installing such systems, it must be ensured that the building or residency has enough space for their installation. It must always be ensured that air ducts are cleaned properly or else pathogens will start thriving in them and cause problems.
