HVAC is a vehicular and indoor environment technology meant for offering a comfort environment. The goal of this technology is to ensure thermal comfort as well as acceptable indoor air quality. The design of these systems is a sub-discipline within the field of mechanical engineering. It is based on the principles of heat transfer, fluid mechanics, and thermodynamics. When in need of the best companies that specialize in HVAC Louisville KY is a good place to consider visiting.
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 in HVAC systems is usually achieved heaters. A central heating unit is a good example of a heater. Heaters consist of a heat pump, boiler, and a furnace. These components are used for heating air, water, or steam in a central place before being distributed to places where heat is required. Process involved in the transfer of heat include convention, radiation, and conduction.
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.
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.
Furnaces, boilers, and space heaters are not supposed to be used for indoor heating. They are unsafe because they do not bun fuels completely. The lack of oxygen is the cause for the incomplete combustion, something that lead to production of combustion byproducts such as volatile organic compounds, carbon monoxide, nitrogen oxides, and formaldehyde.
Of all the byproducts of combustion, carbon monoxide is the most dangerous. At concentrations of several hundred ppm, it can induce vomiting, nausea, fatigue, and headaches in people. However, when the concentration rise to 1000 ppm, it becomes lethal. The gas is made even more dangerous by the fact that it is odorless, tasteless, and colorless.
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.
