HVAC refers to an indoor or vehicular environment technology that is designed to offer comfort in the space it is installed. The technology is designed to ensure acceptable indoor air quality and thermal comfort. The designing of HVAC systems is often undertaken under a sub-field of mechanical engineering. Heat transfer, thermodynamics, and fluid mechanics are some of the principles upon which the design is based. When in need for companies with specialty in HVAC Louisville KY offers the best location to prioritize.
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 is usually done by heaters. An example of a heater is a central heating unit. A heater is usually comprised of a furnace, boiler, and a heat pump. These components are needed for heating air, steam, or water in a central location for it to be distributed throughout the home. The transfer of heat is done through three major processes, that is, radiation, conduction, and convention.
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.
Piping is often used for the transfer of heat to various sites in systems that use water or steam for heating. A circulator is used for moving water or steam around the distribution system. A circulator is simply a pump that pumps water or steam around. The transfer of heat to the surroundings is done using various kinds of heat exchangers such as radiators and water coils. The various exchangers may be installed in the floor or the walls.
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.
Carbon monoxide is the most dangerous byproduct of combustion. When the concentration is a couple hundred ppm in a room, occupants start to feel nausea, headaches, fatigue, and vomiting. When the concentration in raised to about 1000 ppm, it is considered lethal. The lack of smell, color, and taste make it even more dangerous.
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.
