Abstract

A first ventilation apparatus of ventilation apparatuses which form a ventilation system includes: a first information transmission part (18a); a first information reception part (19a); and a first control part (17a). The first control part (17a) includes: a first total ventilation air volume determination part (20a); a first-ventilation-apparatus first air volume decision part (21a); and a first air volume detection part (22a).

First claim

The invention claimed is:

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; and
a 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; and
a 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; and
an 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; and
an 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,

each of the first ventilation apparatus and the mth ventilation apparatus further comprises a floor area setting part which sets a total floor area of the house,
each of the first information transmission part and the mth information transmission part transmits information on the set total floor area,
the first information reception part receives information on the total floor area set in the mth ventilation apparatus,
the mth information reception part receives information on the total floor area set in the first ventilation apparatus to the (m−1)th ventilation apparatus and the (m+1)th ventilation apparatus to the nth ventilation apparatus, and
each of the first total ventilation air volume determination part and the mth total ventilation air volume determination part calculates the total ventilation air volume based on a largest one of the total floor areas.

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; and
a 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; and
a 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,

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; and
an 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; and
