How HVAC Systems Work

The primary function of the HVAC system in your home the (heating, ventilation and air condition system) is to provide thermal comfort with the control the temperature and produce acceptable indoor air quality by controlling humidity and filtering the air in the room. There are many heating and air conditioning systems to choose from today. Your HVAC system dealer can draw on a vast degree of heating and air conditioning knowledge and experience to help you decide on what HVAC system that best fits your specific needs. The size of your home, as well as the number of rooms, climate, local and regional utility costs, and utility incentive programs are all factors that will affect the functionality and, the type you wanted for your HVAC system.

Types of Commercial HVAC System
Commercial structures can benefit from a number of interconnected systems that provide heating and cooling to individual floors or other areas. Some you may see in a large-scale commercial HVAC system that includes:

• Heat Pumps extract heat from air or water for heating like a refrigerator in reverse. In a water source heat pump, a pipe carries water through the structure to supply the heat pump.
• Roof top units are found on the roof or ground and duct the conditioned air into the space. They’re very common in commercial HVAC applications in New York.
• Chillers generate cool water distributed to air cooling coils via piping systems.
• Heaters come in two types – common hot air furnaces that burn fuel to heat the air, and radiant heaters that use invisible infrared radiation to heat objects directly.

The heating, ventilation and air conditioning or HVAC system of any building is like the respiratory system of a human being. It controls the movement, quality and temperature of air to ventilate, warm and cool the organism. Energy is consumed by the parts of the system that heat and cool the air and movement of air with fans requires energy. Air or water is heated or cooled using direct contact with heat or refrigerants and pushed through pathways thru ducts or tubes, escaping through outlets or vents until it travels throughout the structure. The air or water then returns to its origin to be heated or cooled again. Well-engineered ventilation patterns aid circulation, introduce fresh air and controls the build-up of carbon dioxide, carbon monoxide  and miscellaneous toxic gases from building materials and household activities.

Here are the three main functions of your HVAC system and how they work:

Heating
Heating function of your HVAC system does heats your home. This is done via a central heating system. The surrounding air enters the unit and is warmed by a heat pump furnace system. With a heat pump or warm air system, heat is distributed through a system of air ducts in the home.

Ventilation
The ventilation function of your HVAC system works to maintain the highest possible air quality inside your home. High air quality is achieved by ventilating air through a series of ducts and circulating the air back into the home. The air can be exchanged with outdoor air and circulated from air within the building.

Air Conditioning
Air conditioning systems are often misunderstood, as many believe they cool the air inside your home. The air conditioning function of your HVAC system North Las Vegas works by removing humidity from the air, and then using a refrigeration system to remove heat from the air. This removal of moisture and heat creates a cooling effect.

Well-designed HVAC systems, passive filters, insulation and gravity make the system more effective and efficient. New conservation practices and systems using alternative energies are being designed to improve efficiency.
