Cold or warm wind controlling device

Abstract

Abstract PURPOSE: To improve the workability of air piping by unitizing air piping between a multizone unit and a temperature adjusted zone. CONSTITUTION: Air piping between a multizone unit 10 which serves as a cold air source and a warm air source and a temperature adjusted zone is constructed in such a way that it has dampers 17 and 18 which compose a variable adjusting valve, is divided into two lines at the position where the dampers 17 and 18 are installed and has a duct 16 which has plural air outlets 21 in the temperature adjusted zone 20. A warm air side damper 13 and a cold air side damper 14 of the multizone unit 10 and the dampers 17 and 18 are controlled by a control computer 19 to open or close corresponding to load conditions in the temperature adjusted zone 20 and the lines communicating with the temperature adjusted zone 20. By so doing, air piping from the cold air and warm air sources to the temperature adjusted zone 20 can be constructed of a single air pipe, and thus the desired purpose can be attained.
