HVAC From Wikipedia, the free encyclopedia. HVAC may also stand for High-voltage alternating current Software being used to design HVAC systems HVAC (pronounced either "H-V-A-C" or, occasionally, "H-VAK") is an initialism acronym that stands for " heating, ventilation and air-conditioning ". This is sometimes referred to as climate control These three functions are closely interrelated, as they control the temperature and humidity of the air within a building in addition to providing for smoke control, maintaining pressure relationships between spaces, and providing fresh air for occupants. In modern building designs, the design, installation and control systems of these functions are integrated into a single "HVAC" system. The term air handler can mean a whole unit including the blower, heating and cooling elements, filter racks or chamber and dampers, but not including the ductwork through the building.

HVAC/R, Heating Ventilating, Air Conditioning and Refrigeration, is big business with large companies providing equipment, design services and installation. Small and large companies provide many support services. Many companies and individuals of many organizations help oil the wheels of commerce in this area with a variety of supporting products and services that range from specialty sensors to software to consulting and training. It is an activity that consumes a very large number of temperature sensors and humidity sensors. It is an area of activity that has many highly trained people, like engineers and scientists that develop and engineer equipment and projects. Other, less-highly trained people, such as technicians, support the equipment in use to heat and cool residential buildings, commercial buildings, factories, plant process equipment and more. It is an industry in itself that goes far beyond just the use of sensors and controls. However, without the sensors it would be neither as dynamic nor as efficient as it is. There are, needless to say, several websites that deal exclusively with the HVAC industry and its many faces. This page will try to act as a guide to the pages that seem most useful and worthy of your visits in terms of the sensors and their uses in the various conditions of measurement encountered in HVAC/R

76. HVAC Control Tutorial - HomeTech Solutions Most modern thermostats and hvac control systems operate on a 24VAC standard . The vast majority of domestic hvac control systems fit into this category. http://www.hometech.com/learn/hvac.html

HVAC Control Tutorial by Jeff Fisher are pretty massive. They include large ducts that are built-in-place by slicing and bending sheet metal (often by hand). And they draw lots of power and fuel to operate. While HVAC manufacturers are gradually becoming more sophisticated, our experience with HVAC installers has shown that they are still more comfortable bending tin than pushing electrons. A homeowner that desires anything more elaborate than a single thermostat must design and procure the control portion of the system themselves. Although this may seem like a daunting task, let me assure you that it really isn't that difficult. As with many "trade" oriented subjects, it just hasn't been written about publicly very much...until now. Let the professionals design and install your HVAC system and ducting, we'll show you how to design and install the control system. Types Of HVAC to Thermostat Connections 220V Baseboard Millivolt Heat Only 24VAC Heat/Cool Non-Heat Pump ... Adding a Remotely Controllable Thermostat Types Of HVAC to Thermostat Connections The first thing I have to say here is that the HVAC industry is the least "standardized" of any I have seen. The best word I can think of to describe the HVAC industry is "casual." Every rule has many exceptions...and nobody seems to worry about the lack of standardization much. But it is still useful to detail the few de-facto standards so you will have a starting point to understanding specific setups.
