What Does HVAC Stand For – Definition
HVAC stands for Heating, Ventilation and Air Conditioning. Some people also refer it as “heating, ventilating, and air conditioning”. The HVAC was invented by a group of key people including Nikolay Lvov, Michael Faraday, James Joule, William Rankine, Willis Carrier, Reuben Trane, Sadi Carnot and many others.
Centralized air conditioners or split systems constitute of an condenser (outdoor unit) and an evaporator coil (indoor unit) which function to transmit heat from one unit to the other. An air handler or furnace is generally installed along with it. HVAC equipments uses an effective control system to regulate the function of a heating or air conditioning system. To make a comparison between the temperature states, a sensing device is generally made use of. It helps to compare the temperature state with a desired/target state easily. And finally the control system decide and implement the conclusion what action needs to be done for achieving the desired temperature (e.g. start the blower).
Heating, Ventilation and Air Conditioning (HVAC) is widely used in the medium to large size of home and commercial buildings where fresh air is regulated from the outdoors. The three functions of heating, ventilation and air conditioning are closely inter-related to provide quality thermal comfort and quality indoor air freshness.
A central HVAC system is the most useful for convenient way to control temperature of the entire home.
Unless you live in a balanced climate, it is calculated that your HVAC system consumes more than 40 percent of electricity in your home. However you can cut down the electricity bills by almost half by simply maintaining and upgrading your HVAC equipment.
An HVAC system deals in performing a gamut of activities that may consist of maintaining the air quality standard, temperature moderations, humidity control and so on…
