HVAC is a technology designed to offer comfort in vehicular or indoor environments. The objective of the technology is ensuring that indoor environments have quality air and thermal comfort. These units are designed under a branch of mechanical engineering. Thermodynamics, fluid mechanics, and heat transfer are among the principles on which manufacturers base the production. When in search for firms specializing in HVAC Louisville KY should be the location to put first on a search list.
The design, control systems, and installation of these functions in modern buildings are usually integrated into one or multiple HVAC systems. If the building is very small, it is the responsibility of contractors to estimate capacity, engineer, and choose the equipment to be installed. In large building, these functions are undertaken by mechanical engineers, building services engineers, or building service designers. These professionals design, specify, and analyze which systems to install.
Heating operation in HVAC systems is done using heaters. One major example of a heater is the central heating unit. This unit is made up of a boiler, heat pump, and furnace. These parts are meant for heating fluids in a centralized place. After the fluids are heated, they are moved through a distribution systems in the form of piping in all places where heat is needed. Radiation, conduction, and convention are examples of heat transfer methods employed.
Fuels used by heaters are many and diverse. The various models use different fuels to function. Fuels used in central heating units may be in gaseous, liquid or solid form. Many modern models today use electricity. Electricity is used to heat fluids through resistance-type heating elements. They have a higher level of efficiency and convenience, even though they may cost much more.
If the system uses steam or water for heating, piping is used for transporting heat to various locations in the building. The water or steam is moved through the distribution system by a circulator. A circulator is usually a pump used for moving the water or steam. Various heat exchangers such as hot water coils or radiators are used to transfer heat to surrounding air. Heat exchangers are mounted in the walls or floor.
Boilers, space heater, and furnaces must never be used to heat indoor spaces. These products are made unsafe due to incomplete combustion of fuels. Because they do not burn fuels to completion, they result in the emission of volatile organic compounds, formaldehyde, carbon monoxide, and nitrogen oxides among several other combustion byproducts. Incomplete combustion often results because of lack of sufficient oxygen.
Of all the byproducts of combustion produced due to incomplete combustion, carbon monoxide poses the biggest threat. It can cause headaches, vomiting, nausea, and fatigue in small concentrations. However, beyond 1000 ppm of concentration, it becomes highly lethal. It is made even more dangerous by lack of color, taste, and smell. These qualities make it hard to detect the presence of the gas in the room.
There are several different models of HVAC on the market. The number of manufacturers also continues to rise yearly. The efficiency of these products is usually highly dependent on the maintenance they are given.
