Air conditioning equipment for air-return area or room by using damper-diffuser integrated motorized diffuser

Abstract

The present invention relates to air conditioning equipment for an air-return area or room by using a damper-diffuser integrated motorized diffuser which has both a damper function to open or interrupt the flow of air and a diffuser function to diffuse air therearound. As the present invention uses a damper-diffuser integrated motorized diffuser in air conditioning equipment for an air-return area or room, in addition to an effect of the damper-diffuser integrated motorized diffuser, each one of an air supply duct and a discharge duct can be configured, such that the present invention can be installed within a narrow ceiling space, and as a result, room-unit air conditioning or area-unit air-conditioning is enabled and further an installation cost thereof can be low.

1 . Air conditioning equipment for an air-return area or room by using a damper-diffuser integrated motorized diffuser that supplies air processed from an air conditioner to each area or each of rooms and discharges or recirculates (ventilates) the air within the areas (rooms) to the outside, comprising:
 one air supply duct for supplying the air processed from the air conditioner to each area or each of the rooms;   a damper-diffuser integrated motorized diffuser including a diffuser cone and a diffuser casing installed in each area or each of the rooms and connected to be in communication with the air supply duct and forming an air flow passage between outer peripheries opposite to each other and a motor means actuating the diffuser cone with respect to the diffuser casing to control an opening rate of the air flow passage or open/close the air flow passage with diffusion of air;   an area (room) controller including a control unit for controlling the motor means of the integrated motorized diffuser; and   a discharging duct for discharging or recirculating (ventilating) the air within each area or each of the rooms to the outside or an induction duct to a ceiling space.   
     
     
         2 . The air conditioning equipment for an air-return area or room by using a damper-diffuser integrated motorized diffuser of  claim 1 , wherein the integrated motorized diffuser is installed in the discharging duct or the induction duct. 
     
     
         3 . The air conditioning equipment for an air-return area or room by using a damper-diffuser integrated motorized diffuser of  claim 2 , wherein the air conditioner is any one of heat pumps separated air conditioners, and integrated air conditioners. 
     
     
         4 . The air conditioning equipment for an air-return area or room by using a damper-diffuser integrated motorized diffuser of  claim 1 , wherein the diffuser cone includes a diffuser cone body forming an air flow passage on outer peripheries between the diffuser cone and the diffuser casing when the diffuser cone is opened with respect to the diffuser casing, a diffuser cone cover forming a space part between the diffuser cone and the diffuser cone body and removably fixed to the diffuser cone body, and the motor means fixedly installed in the space part.
