Claims

[Claim for Utility Model Registration] In an air conditioner and its system that have a capacity-controllable refrigeration cycle using a pole converter compressor and that air condition multiple rooms using a duct connection method, By installing several damper devices for opening and closing passages in each room and controlling the capacity, depending on the operating pattern of each room, (1) the function of appropriately controlling the amount of cycle refrigerant circulating, and (2) the function of controlling the amount of refrigerant in each room. (3) A mechanism that switches the rotation speed of the indoor fan motor into several stages, and a mechanism that switches the rotation speed of the outdoor fan motor into several stages. A duct type air conditioner characterized by having the following functions.
