Changing a vapour (or gas) into a liquid This change is accompanied by a giving out of energy
These units are super efficient with some designs reaching AFUEs of up to 97 percent Unlike conventional forced air furnaces, condensing units capture most of the water vapor and heat contained in hot flue gases that would normally escape up the chimney The escaping gases then pass through a second heat exchanger and condensate is expelled The heat exchangers are made of corrosion resistant stainless steel, and many have lifetime warranties Exhaust is cooler than that of conventional furnaces and can be vented with PVC piping
When a gas or vapour condenses, or is condensed, it changes into a liquid. Water vapour condenses to form clouds The compressed gas is cooled and condenses into a liquid
If you condense something, especially a piece of writing or speech, you make it shorter, usually by including only the most important parts. We have learnt how to condense serious messages into short, self-contained sentences
undergo condensation; change from a gaseous to a liquid state and fall in drops; "water condenses"; "The acid distills at a specific temperature" compress or concentrate; "Congress condensed the three-year plan into a six-month plan" develop due to condensation; "All our planets condensed out of the same material" become more compact or concentrated; "Her feelings condensed" cause a gas or vapor to change into a liquid; "The cold air condensed the steam" remove water from; "condense the milk
