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.
Heaters use a wide range of fuels for heating. There are different models of heater, and each may use different energy source. Fuels may be in the form of solid, liquid, or gas. Electricity is also gaining popularity as a source of energy in modern models. Electricity is used to heat resistance coils, which in turn heat up fluids. The heated fluid generates the required heat, which is circulated around.
The transfer of water/steam within the building is achieved through piping systems. The movement of water/steam is done using a circulator through the distribution system. A circulator functions to pump the fluid around the rooms. Radiators, water coils and other kinds of heat exchangers are used to transfer heat to surroundings. Heat exchangers can be installed in various locations in rooms, including walls, ceilings, and floors.
Space heater, boilers, and furnaces should not be used as methods of indoor heating. This is because these structures often result in incomplete combustion of fuel. As a result, they may cause emission of nitrogen oxides, volatile organic compounds, formaldehyde, and carbon monoxide among other byproducts of combustion. The cause of incomplete combustion is usually lack of enough oxygen gas to support the combustion.
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.
