absolute humidity The weight of water vapor per unit volume; grains per cubic foot; or grams per cubic meter absolute pressure The sum of gauge pressure and atmospheric pressure Thus, for example, if the gauge pressure is 154 psi (pounds per square inch), the absolute pressure will be 154 + 147, or 1687 psi absolute zero A temperature equal to -4596 degrees F or -273 degrees C At this temperature the volume of an ideal gas maintained at a constant pressure becomes zero absorption The action of a material in extracting one or more substances present in the atmosphere or a mixture of gases or liquids accompanied by physical change, chemical change, or both acceleration The time rate of change of velocity It is the derivative of velocity with respect to time accumulator A shell placed in a suction line for separating the liquid entrained in the suction gas A storage tank at the evaporator exit or suction line used to prevent floodbacks to the compressor acrolein A warning agent often used with methyl chloride to call attention to the escape of refrigerant The material has a compelling, pungent odor and causes irritation of the throat and eyes Acrolein reacts with sulfur dioxide to form a sludge ACR tube A copper tube usually hard drawn and sold to the trade cleaned and sealed with nitrogen inside to prevent oxidation Identified by its actual outside diameter (OD) activated alumina A form of aluminum oxide (Al2O3) that absorbs moisture readily and is used as a drying agent adiabatic Referring to a change in gas conditions where no heat is added or removed except in the form of work adiabatic process Any thermodynamic process taking place in a closed system without the addition or removal of heat adsorbent A sorbent that changes physically, chemically, or both during the sorption process
aeration Exposing a substance or area to air circulation agitation A condition in which a device causes circulation in a tank containing fluid air, ambient Generally speaking, the air surrounding an object air changes A method of expressing the amount of air leakage into or out of a building or room in terms of the number of building volumes or room volumes exchanged per unit of time air circulation Natural or imparted motion of air air cleaner A device designed for the purpose of removing airborne impurities such as dust, gases, vapors, fumes, and smoke An air cleaner includes air washers, air filters, electrostatic precipitors and charcoal filters air conditioner An assembly of equipment for the control of at least the first three items enumerated in the definition of air conditioning air conditioner, room A factory-made assembly designed as a unit for mounting in a window, through a wall, or as a console It is designed for free delivery of conditioned air to an enclosed space without ducts air conditioning The simultaneous control of all, or at least the first three, of the following factors affecting the physical and chemical conditions of the atmosphere within a structure temperature, humidity, motion, distribution, dust, bacteria, odors, toxic gases, and ionization most of which affect human health or comfort air-conditioning system, central fan A mechanical indirect system of heating, ventilating, or air conditioning in which the air is treated or handled by equipment located outside the rooms served, usually at a central location and conveyed to and from the rooms by means of a fan and a system of distributing ducts air-conditioning system, year round An air-conditioning system that ventilates, heats, and humidifies in winter, and cools and dehumidifies in summer to provide the desired degree of air motion and cleanliness
