1. A hair drying system comprising:
a first duct configured to conduct a first airflow that is at a first temperature; a second duct configured to conduct a second airflow that is at a second temperature lower than the first temperature; first outlets that are spaced apart along the first duct ; second outlets that are spaced apart along the second duct and equal in number to first outlets; dryer handpieces equal in number to the first outlets; Y-couplers, each Y-coupler including:
a first conduit connected to a respective one of the first outlets,a second conduit connected to a respective one of the second outlets, anda third conduit connected to a respective one of the dryer handpieces, for the coupler to combine a portion of the first airflow with a portion of the second airflow to yield a third airflow exiting the respective handpiece;first dampers, each first damper configured to control the first portion of the first airflow;second dampers, each second damper configured to control the second portion of the second airflow;and a programmable central control system configured to:
control pressure of the first airflow,control pressure of the second airflow,control the first temperature; andfor each handpiece, control the first damper and the second damper that are associated with the respective handpiece to control temperature of the third airflow exiting the handpiece. |
