1. A ventilation apparatus installed inside a house, and constituting a ventilation system with other ventilation apparatuses connected through a single system of information transmission network for maintaining a ventilation air volume in the house constant,
wherein the ventilation system comprises n sets of the ventilation apparatuses designated as a first ventilation apparatus to an nth ventilation apparatus where n is an integer of 2 or more, the first ventilation apparatus comprises:
a first information transmission part configured to transmit information to the second ventilation apparatus to the nth ventilation apparatus through the information transmission network;a first information reception part configured to receive information on the second ventilation apparatus to the nth ventilation apparatus through the information transmission network; anda first control part configured to decide operation of the first ventilation apparatus, the first control part comprises:
a first total ventilation air volume determination part configured to determine a total ventilation air volume necessary for the house;a first-ventilation-apparatus first air volume decision part configured to decide a first-ventilation-apparatus target air volume necessary for maintaining the total ventilation air volume based on the information on the second ventilation apparatus to the nth ventilation apparatus received by the first information reception part; anda first air volume detection part configured to detect a first-ventilation-apparatus output air volume which the first ventilation apparatus actually outputs, and, when the first-ventilation-apparatus output air volume differs from the first-ventilation-apparatus target air volume, inform the second ventilation apparatus to the nth ventilation apparatus of the first-ventilation-apparatus output air volume as a preferential air volume, through the first information transmission part, the mth ventilation apparatus, where m is any of integers that satisfy 2≦m≦n, comprises:
an mth information transmission part configured to transmit information to the first ventilation apparatus to the (m−1)th ventilation apparatus and the (m+1)th ventilation apparatus to the nth ventilation apparatus through the information transmission network;an mth information reception part configured to receive information on the first ventilation apparatus to the (m−1)th ventilation apparatus and the (m+1)th ventilation apparatus to the nth ventilation apparatus through the information transmission network; andan mth control part configured to decide operation of the mth ventilation apparatus, the mth control part comprises:
an mth total ventilation air volume determination part configured to determine the total ventilation air volume;an mth-ventilation-apparatus first air volume decision part configured to decide an mth-ventilation-apparatus target air volume necessary for maintaining the total ventilation air volume based on the information on the first ventilation apparatus to the (m−1)th ventilation apparatus and the (m+1)th ventilation apparatus to the nth ventilation apparatus received by the mth information reception part; andan mth air volume detection part configured to detects an mth-ventilation-apparatus output air volume which the mth ventilation apparatus actually outputs, and, when the mth-ventilation-apparatus output air volume differs from the mth-ventilation-apparatus target air volume, inform the first ventilation apparatus to the (m−1)th ventilation apparatus and the (m+1)th ventilation apparatus to the nth ventilation apparatus of the mth-ventilation-apparatus output air volume as a preferential air volume, through the mth information transmission part. |
