qanat's Usage Examples:

The air is also evaporatively cooled when some of the water in the qanat evaporates as the hot, dry surface air passes over it; the heat energy in the air is absorbed as energy of vaporization.

In dry desert climates this can result in a greater than 15"nbsp;°C (27"nbsp;°F) reduction in the air temperature coming from the qanat.

qanat system from Persia, regional water-lifting devices such as the noria, shaduf and screwpump from Egypt, and the windmill from Islamic Afghanistan.

the wind, passed it over subterranean water in a qanat and discharged the cooled air into the building.

Incoming air is pulled from a qanat below the house.

The hot air is brought down into the qanat tunnel and is cooled by coming into contact with the cool earth and the cold water running through the qanat.

The air flow across the vertical shaft opening creates a lower pressure (see Bernoulli effect) and pulls cool air up from the qanat tunnel below the house.

Windcatchers are used for evaporative cooling in combination with a qanat, or underground canal (which also makes use of the subterranean heat reservoir described above).

Later these structures came to be called zanāneh (feminine residence), andaruni (inner private zone) and haram (from Arabic [Dictionary|Dehkhoda Persian Dictionary]CoolingA shabestan can be cooled using a qanat in conjunction with a windcatcher.

These spaces were usually used during summers and could be ventilated by windcatchers and qanats.

The air from the qanat was drawn into the tunnel at some distance away and is cooled both by contact with the cool tunnel walls/water and by the giving up of latent heat of evaporation as water evaporates into the air stream.
