<p>PURPOSE:To make a main space matched to a user's life behavior pattern even in a wide installing room comfortable and to provide energy conservation by air conditioning a specific zone. CONSTITUTION:When an operation command for air conditioning a specific zone is input to an air conditioning zone switching controller, air conditioning is conducted in a normal operation in an outlet 3 disposed at the specific zone side, and diffusing opening regulating means 6 narrows the diffusing opening area in an outlet 4 of the opposite side in cooperation with the above operation to throttle the diffused air thereby to form an air curtain from the outlet 4 toward the down direction. Thus, the specific zone can be air conditioned. The air flow rate from the outlet 4 to form the curtain is automatically set to a low flow rate. Further, the command is input to the controller to switch the outlets 4, 3 for air conditioning in the normal operation or the outlets 4, 3 for forming the curtain.</p> |
