What is HVAC?
HVAC is an abbreviation for Heating, Ventilating, and Air Conditioning. The HVAC systems are mostly used in apartment buildings, commercial buildings like schools, universities, hospitals, offices, airports, and industrial buildings like warehouses, manufacturing plants, factories.
Why is HVAC used?
Ventilation is vital for air circulation in crowded buildings; Be it a school, university, even an airport building. Apart from the very reason in which HVAC systems help, there are other factors why HVAC is commercially used by multiple companies-
- The air-conditioning during summer keeps the temperature low and maintains a humidity level using the cooling system.
- Heating during winter is done by heating the air within the building using radiators.
- The polluted air is extracted by air vents from the building by pulling the air out and clean air is circulated within the building by fans.
- A temperature of 75 to 77 degrees Fahrenheit is ideally kept.
Types of HVAC systems
- Decentralized or Individual systems- Rooftop HVAC system is an example of an individual system. Easy to control and ask for low investments to be made for self/individual use. This kind of system might cause an issue in large systems since breakage and leakage would require a large part of the system to be replaced in order to be used correctly.
- Packaged system- When there is compact space but it calls for air conditioning and heating systems to be installed together; the packaged system is used. This system contains-
- Optional air purifiers, cleaners, ventilators, UV lamps in order to make the air extra clean.
- Control interface for complete control of the system.
- The evaporation of the heating system and the air fan of the air conditioner is packed as one.
- Centralized system- The name itself defines the work. The system supplies the HVAC needs of the entire building with one system itself. The system has quite a high amount of load management, also uses water for cooling and distributes it through ducts.
Features of the HVAC system you must check before buying
- How durable the entire system is. The system must ensure the withstanding capability from all the meteorological extreme like heavy rain, snow, heat.
- Rooftops are the only available space in the building which can be used without compromising on accommodation and necessary spaces. The need of venting out the hot air outside makes rooftop placement a good choice; the vents can be easily put out without compromising on parking spaces and avoid usage of too many vents making the installation complex.
- A modular system helps in adding and subtracting units from the system as needed.
The HVAC or Heating, Ventilating, Air Conditioning system is vital to a building. A comfortable, healthy, energy-efficient feature for a building is necessary for it to provide its service. All HVAC installations are not the same, the installation depends on the size of the system (centralized, individual, package system), location, including building size. The system should also ensure energy consumption in order to pull out a reasonable bill amount.
