  1. calefaction

    Heating, ventilation, and air conditioning (HVAC) is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. "Refrigeration" is sometimes added to the field's abbreviation as HVAC&R or HVACR, or "ventilation" is dropped, as in HACR (as in the designation of HACR-rated circuit breakers). HVAC is an important part of residential structures such as single family homes, apartment buildings, hotels, and senior living facilities; medium to large industrial and office buildings such as skyscrapers and hospitals; vehicles such as cars, trains, airplanes, ships and submarines; and in marine environments, where safe and healthy building conditions are regulated with respect to temperature and humidity, using fresh air from outdoors. Ventilating or ventilation (the "V" in HVAC) is the process of exchanging or replacing air in any space to provide high indoor air quality which involves temperature control, oxygen replenishment, and removal of moisture, odors, smoke, heat, dust, airborne bacteria, carbon dioxide, and other gases. Ventilation removes unpleasant smells and excessive moisture, introduces outside air, keeps interior building air circulating, and prevents stagnation of the interior air. Methods for ventilating a building are divided into mechanical/forced and natural types.

  3. Etymology: [L. calefactio: cf. F. calfaction.]


  1. Calefaction

    Calefaction comes from the Latin calor meaning "heated", and facere "to make." Generally, that is what the term means: to heat, or make heated. In the modern sciences, the term calefaction shows up occasionally in relation to the fields of cryogenics, geology, mineralogy, inorganic chemistry, material sciences, and both scientifically and commercially in the study and process of sintering. One example of the usage of the term is given by the French chemist and pharmacologist Pierre H. Boutigny, who became known for his "calefaction experiments," where he studied and expanded our understanding of what is known as the Leidenfrost Phenomenon, which appropriately describes the effect of a liquid on a heated interface above and near the liquids boiling point. The term calefaction has also been used in the manufacturing of steam engines and steam cars. Two examples of this are the Serpollet generator and the Paul Jacquot engine.
