What is it HVAC? You've probably heard this expression, but you are still wondering what it means?
Well, HVAC (HVAC "or" H-VAK ") is the abbreviation for "Heating, Ventilation and Air Conditioning", i.e, Heating, Ventilation and Air Conditioning. These are three fundamental functions that are closely related., found in homes, offices and buildings.
The start of HVAC is not clear, although as early as the 2nd century many Roman cities used a central heating system known as a hypocaust. HVAC became even more popular during the Industrial Revolution, with the emergence of large factories. Currently, most modern buildings have integrated HVAC.
The HVAC system is also known as climate control.. This is because these three functions are essential to maintain comfort in each room..
The primary use of HVAC is to regulate the ambient temperature., humidity and air flow, ensuring that these elements remain within their acceptable limits.. Effective factor control minimizes health-related risks. A very humid environment impairs the body's ability to regulate body temperature, as it prevents sweat evaporation. High humidity also decreases physical strength., which usually leads to fatigue. Unhealthy environment can also affect people's ability to think. Hypothermia, heat stroke and hyperpyrexia, between others, are some of the diseases that can also occur..
Three HVAC Functions
OHeating is responsible for maintaining the proper temperature, especially during cooler weather conditions.. There are two classifications of heating.: central and local. The latter is most commonly used because it is more economical.. Oven or boiler, heat pump, and radiator make up the heating system.
AVentilationo, on the other hand, is associated with air circulation. There are many types of ventilation, but they all work similarly. Ventilation is required to allow carbon dioxide to escape and oxygen to enter., making people inhale fresh air. Uncirculated air facilitates the spread of disease, like allergies. Insufficient ventilation often promotes the growth of bacteria and fungi., like molds due to high humidity.
O Air conditioning system controls the heat, as well as ventilation. They usually come in different sizes.. Most air conditioners have large air ducts., that's why it's best to check the environment first to confirm the feasibility of your installation. It is always necessary to ensure the cleaning of air ducts to prevent the transmission of respiratory diseases.
The future of HVAC
How technology has changed in the HVAC field? Well, using PLCs (programmable logic controllers) in HVAC is the trend nowadays. But a large part of HVAC system development lies in the continual change of technology and innovation.. Businesses are embracing wireless technology after they discovered they can control HVAC over the network, using sensors and reducing installation and labor costs. Engineering is focused on further improving this technology through the use of control panels, wireless network sensors and controllers. Probably the only downside is exposure to RF radiation. (radio frequency).
The installation of an HVAC system is essential to achieve maximum comfort and have a healthy environment in our homes, offices and facilities.
