Qanats provided the water supply for ice production.
The ice stored in yakhchāls was often produced from water transported through the qanat system.
Badgirs are often integrated into yakhchāl designs.
Windcatchers facilitate the airflow necessary to regulate the internal temperature of the storage dome.
structural property exploited by
The thick walls of a yakhchal provide high thermal mass, which prevents the heat of the desert sun from penetrating the interior ice storage chamber.
