Air conditioning apparatus
TLDR
In this paper, an air flow rate sensor and throttle valve are provided in a control duct between a supply chamber utilizing double ceilings and the air diffusers in the supply chamber, which can be equalized or can be set to the desired values.Abstract:
An air flow rate sensor and throttle valve which controls the opening of a duct in accordance with the detection signals from the air flow rate sensor are provided in a control duct between a supply chamber utilizing double ceilings and the air diffusers in the supply chamber. The quantities of air fed from the respective air diffusers can be equalized or can be set to the desired values. In this case, since the air blowing can be automatically controlled for each diffuser, it is not necessary to individually adjust the quantities of air for the respective air diffusers after the installation of the air conditioner, thereby eliminating the adjusting works of the air diffusers.read more
