HVAC stands for heating, ventilation and air conditioning. When refrigeration is added then the acronym becomes HVACR. It is the technology that keeps an indoors environment comfortable for those living or working in it, all year round. By environment we do not mean just the temperature. We are also talking about the quality of the air that people breathe inside the various buildings.
By ventilating the air we replenish it inside the area where our system is installed by new clean air. This process also removes the odors, airborne bacteria, smoke and dust, thus providing a better quality of air. Exchanging the air inside a building can be achieved either through the mechanical or forced process which requires fans and pumps to draw the old air out and pull fresh air in, or naturally by opening up windows, doors and other points where fresh air may have access to the interior.
Ventilating naturally is the most essential process for keeping some airborne diseases, like tuberculosis, at bay, while maintaining the pressure at equilibrium. A mechanical or forced ventilation must include provisions and arrangements so that the pressure on the inside does not become imbalanced. This usually happens when the air is drawn out from one side and pulled in from the other. If any of the two processes is interrupted then a pressure imbalance is produced and it may have some very unpleasant side effects.
Heating and air conditioning may provide the means for the temperature control but it is actually the ventilating process that keeps the environment comfortable and healthy by not allowing the air in the interior of a building to remain stagnant. It is all in the laws of thermodynamics, fluid mechanics and heat exchanges that govern the HVAC concept.
Some people prefer to drop the ventilation part and keep only the heating and cooling elements. We strongly recommend against this choice. If anything it is of more use health wise to ventilate an area than regulate its temperature. This is why some people prefer to install ceiling fans only. They ventilate the room and provide some cool during the summer but they keep the air replenished.
All the machinery that works to provide HVAC is interrelated. For smaller spaces the systems available in the market is all that is necessary. An expert estimates the capacity required and then simply installs the appropriate system. Bigger places require a lot more than this. Bigger spaces may even require to order the manufacturing of a specific system so that it can satisfy the needs of a specific environment.
All the above are a clear indication that installing such a system requires well-trained professionals that are experienced enough to supply the appropriate solutions. We at Miami Air Conditioning employ such technicians. People that will visit your house, assess the conditions and then provide the solution that will best match the needs and the available budget.
