What is HVAC? What are its Benefits?

HVAC refers to heating, ventilation and air conditioning and specifically the term HVAC is used to describe the above mentioned phenomenon in the context of an indoor environment. That indoor environment can be a room, a big hall, a huge building, or even a vehicle.

Usually HVAC systems are installed in the more modern establishments even though it is quite an old practice, or a field of study and application. The purpose of any HVAC system, regardless of where it is installed and used, is to provide a healthy level of ventilation and high quality air for people present indoors.

Let us breakdown the few elements of HVAC and see how they are implemented in today’s economic and literal climate.

What is HVAC? What are its Benefits?

Heating

Heat Pumps

Heat pumps are widely used as a method to transfer thermal energy i.e. heat, form one place to another against its natural flow. Although this process is tailor made for efficient, it is also used in air conditioners and refrigerators as it ca take heat away from some place which is ideal in the latter case. On average, heat pumps are fond to be multiple times more effective than electrical heaters.

Furnaces and Boilers

These are central heating systems, the furnace and boilers both have a fuel burning center where air and water heated respectively for both of the systems. This heated air and water is then circulated throughout the house or building with the help of ducts and pipes respectively. The boilers also make use of radiators to warm the room.

Fireplaces

Fireplaces are traditionally not a part of any HVAC system but since the smoke coming out from it or the fuel supply gong to it is directly related to ventilation and heating, sometimes are supply and removal of these items is a part of HVAC.

Stoves

Similar to the above mentioned fireplaces, the ventilation and exhaustion of smoke and stale air is a part of any HVAC system and it would be a good idea to consult HVAC specialists before going ahead with using these items.

 

Air Conditioning

Central and Room Air conditioners

These air conditioners work on the principle of refrigeration and utilize energy to take heat away from an object or area in order to cool the atmosphere. They usually use up a lot of energy and need air tight spaces to effectively work, but in the right situations, they are the best option.

Split Air Conditioners

These are similar to the above ones but their compressor and air handler are separate and only two electrical conduits containing the refrigerant and fuel connect the two separated parts. This allows you to place the compressor outside without needing to make a hole in the wall.

Evaporative Cooling

Evaporative coolers are those which use fresh air and pass it through cold moistened pads to make it cooler. They are very efficient and economical, and work very well in dry areas. You also don’t need air tight spaces for it to function effectively.

 

Ventilation

Heat Recovery

Heat recovery ventilation makes use of the heat contained by outgoing stale exhaust air and use it to cool the incoming air thus greatly reducing your energy expenses while providing you with the right atmosphere, including temperature, pressure and humidity.

Exhaust Fans

Typical means of clearing out stale warm air, the exhaust fans are cheap and very easy to use for everyone and can be found at any store.
