Air conditioning is the cooling and dehumidification of indoor air for thermal comfort Human thermal comfort is defined by ASHRAE as the state of mind that expresses satisfaction with the surrounding environment . Maintaining thermal comfort for occupants of buildings or other enclosures is one of the important goals of HVAC design engineers. In a broader sense, the term can refer to any form of cooling, heating, ventilation HVAC is an acronym that stands for the closely related functions of "Heating, Ventilating, and Air Conditioning"- the technology of indoor environmental comfort. HVAC system design is a major subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. Refrigeration is sometimes, or disinfection Disinfectants are antimicrobial agents that are applied to non-living objects to destroy microorganisms, the process of which is known as disinfection. Disinfection is defined as: Cleaning an article of some or all of the pathogenic organisms which may cause infection Disinfectants should generally be distinguished from antibiotics that destroy that modifies the condition of air.[1] An air conditioner An air conditioner is a home appliance, system, or mechanism designed to dehumidify and extract heat from an area. The cooling is done using a simple refrigeration cycle. In construction, a complete system of heating, ventilation, and air conditioning is referred to as "HVAC." Its purpose, in a building or an automobile, is to provide (often referred to as AC or air con.) is an appliance A major appliance, or domestic appliance, is usually defined as a large machine which accomplishes some routine housekeeping task, which includes purposes such as cooking, food preservation, or cleaning, whether in a household, institutional, commercial or industrial setting. An appliance is differentiated from a plumbing fixture because it uses, system System is a set of interacting or interdependent entities forming an integrated whole, or machine A machine is any device that uses energy to perform some activity. In common usage, the meaning is that of a device having parts that perform or assist in performing any type of work. A simple machine is a device that transforms the direction or magnitude of a force without consuming any energy. The word "machine" is derived from the designed to stabilise the air temperature and humidity within an area (used for cooling as well as heating depending on the air properties at a given time), typically using a refrigeration cycle Thermodynamic heat pump and refrigeration cycles are the models for heat pumps and refrigerators. The difference between a heat pump and a normal air conditioner is that a heat pump can be used to heat a home as well as cool it. Even though the heat pump can heat, it still uses the same basic refrigeration cycle to do this. In other words a heat but sometimes using evaporation Evaporative cooling is especially well suited for climates where the air is hot and humidity is low. For example, in the United States, the western/mountain states are good locations, with swamp coolers very prevalent in cities like Denver, Salt Lake City, Albuquerque, El Paso, Tucson, and Fresno where sufficient water is available. Evaporative, commonly for comfort cooling in buildings and motor vehicles.
The concept of air conditioning is known to have been applied in Ancient Rome Ancient Rome was a civilization that grew out of a small agricultural community founded on the Italian Peninsula as early as the 10th century BC. Located along the Mediterranean Sea, it became one of the largest empires in the ancient world, where aqueduct An aqueduct is a water supply or navigable channel constructed to convey water. In modern engineering, the term is used for any system of pipes, ditches, canals, tunnels, and other structures used for this purpose. In a more restricted use, aqueduct (occasionally water bridge) applies to any bridge or viaduct that transports water—instead of a water was circulated through the walls of certain houses to cool them. Similar techniques in medieval The Middle Ages is a period of European history covering roughly a millennium from the 5th century through to the 16th century. It is commonly dated from the fall of the Western Roman Empire, and contrasted with a later Early Modern Period; the time during which the rise of humanism in the Italian Renaissance and the Reformation unfolded, are Persia Iran (Persian: ایران [ʔiˈɾɒn] ), officially the Islamic Republic of Iran is a country in Western Asia. The name Iran has been in use natively since antiquity and came into international use in 1935, before which the country was widely known as Persia. Both Persia and Iran are used interchangeably in cultural contexts; however, Iran is the involved the use of cisterns A cistern is a receptacle for holding liquids, usually water. Often cisterns are built to catch and store rainwater. They range in capacity from a few litres to thousands of cubic metres (effectively covered reservoirs) and wind towers A windcatcher is a traditional Persian architectural device used for many centuries to create natural ventilation in buildings. It is not known who first invented the windcatcher, but it still can be seen in many countries today. Windcatchers come in various designs, such as the uni-directional, bi-directional, and multi-directional. Examples of to cool buildings during the hot season. Modern air conditioning emerged from advances in chemistry Chemistry (from Arabic: كيمياء Latinized: chem , meaning "earth") is the science concerned with the composition, behavior, structure, and properties of matter, as well as the changes it undergoes during chemical reactions. It is a physical science for studies of various atoms, molecules, crystals and other aggregates of matter during the 19th century, and the first large-scale electrical air conditioning was invented and used in 1902 by Willis Haviland Carrier Willis Haviland Carrier was an engineer and inventor, and is known as the man who invented modern air conditioning.
