Absorption -A refrigeration cycle where input energy is heat Adiabatic - without gain or loss of heat Air Conditioning - controlling air temperature humidity and quality Air Cooled Condenser - a heat exchanger that transfers building heat to outdoor air Air Handler - air moving equipment that can change air temperature humidity and quality BTU - British thermal unit. 1 BTU will increase the temperature of 1 lb of water 1 degree F BTUH - Rate of heat flow. BTU per hour C - the tendency to conduct heat for a standard thickness of material CFM - Cubic feet per minute Chiller - a heat exchanger where an evaporating refrigerant chills water Chill Water - water about 45 F use in a heat exchanger to cool and dehumidify an air stream Coil - a heat exchanger Condensation - Change of state from vapor to liquid; heat is releasedConstant Volume - HVAC equipment that controls room temperature by controlling the temperature of conditioning air Cooling Tower - a heat exchanger that transfers building heat to outdoor air by evaporating water COP - coefficient of performance Deck - A heat exchanger Dehumidify - Remove moisture Dry Bulb Temperature - temperature indicated by a standard thermometer DX - Direct expansion EA - Exhaust air Economizer - cooling with outdoor air
