What is HVAC?

HVAC Overview

HVAC stands for heating, ventilating, and air conditioning and is sometimes referred to as climate control. HVAC is usually used for large buildings like skyscrapers because it helps control the interior temperature of those very large buildings. The purpose of HVAC systems is to create acceptable indoor air quality, maintain temperature control, and to provide a system that is cost effective for consumers. HVAC systems stemmed from the industrial revolution and were created to promote higher efficiency heating and cooling systems. HVAC systems can also be used to regulate atmospheres based on humidity and temperature control as in an indoor aquarium. HVAC systems use room air distribution to deliver and remove air from different spaces.

To further help define HVAC it is important to understand the components of heating, ventilating, and air conditioning. Heating is the process of bringing heat to different spaces using a variety of sources. Heating systems usually refer to the way air, water, or steam is heated using a boiler, furnace, or heat pump to then distribute air to a space. This system usually also requires the use of ductwork or piping to distribute air throughout the space. Ventilating is the process of removing or changing air in a space to create a different temperature or to reduce or remove moisture, odors, smoke, dust, or even airborne bacteria within a space. Ventilation is bringing air in from the outside in a circulation system to replace inside air. There are two types of ventilation, natural and forced air ventilation. Last, air conditioning is simply the removal of heat from a space. You can remove heat from a space by using refrigerants like water, ice, air, or other cooler chemicals along with convection, radiation, and conduction.

 

Efficient HVAC Systems Save Your Money

Over the years manufactures have tried to make HVAC systems more efficient and cost effective for consumers due to high energy costs and more consumer environmental awareness. They have done this mainly with forced air systems that provide better heating and cooling for spaces with less energy requirements. This provides lower costs for homes and public buildings.

It is important to maintain efficient systems within buildings in order to provide comfort and good air quality. Ventilating, cooling, and heating can provide much comfort to consumers and help reduce other problems like frozen pipes in winter or airborne bacteria that can reduce the air quality and affect health of its occupants. HVAC systems work in such a way as to reduce air components that are potentially unhealthy and provide more comfort where there was none before.
