The
空調対象である室内においては、空間内において部分的(局所的)に二酸化炭素濃度が高くなってしまう可能性がある。特に、ユーザの周囲領域に二酸化炭素濃度が高くなっている場合には、ユーザは不快と感じやすい。このため、制御部24では、快適性の評価結果が不快と判定された場合に、空調風量を強くして、室内の空気の流れを促し、二酸化炭素を攪拌して、部分的に二酸化炭素濃度が高くなってしまうことを抑制する。なお、空調風量については、例えば室内ファン51の回転数を増加させ、室内に送風される空気量を増加させる。 First, a case in which the air-conditioning air volume is to be controlled will be described.
In a room to be air-conditioned, there is a possibility that the concentration of carbon dioxide will be partially (locally) high in the space. In particular, the user tends to feel uncomfortable when the carbon dioxide concentration is high in the area around the user. Therefore, when the evaluation result of comfort is determined to be uncomfortable, the
図5に示すように、二酸化炭素濃度に対して温度を低下させることによって、ユーザは快適性を感じる傾向にある。このため、制御部24では、快適性の評価結果が不快と判定された場合に、目標温度を低下させ、室内温度が低下するよう制御する。なお、空気調和装置1においては、設定された目標温度に追従するように制御が行われる。 Next, a case in which the target temperature is the object of control will be described.
As shown in FIG. 5, users tend to feel more comfortable by lowering the temperature relative to the carbon dioxide concentration. Therefore, when the evaluation result of comfort is determined to be uncomfortable, the
図5に示すように、二酸化炭素濃度に対して湿度を低下させることによって、ユーザは快適性を感じる傾向にある。このため、制御部24では、快適性の評価結果が不快と判定された場合に、目標湿度を低下させ、室内湿度が低下するよう制御する。なお、空気調和装置1においては、設定された目標湿度に追従するように制御が行われる。 Next, a case in which the target humidity is the object of control will be described.
As shown in FIG. 5, users tend to feel more comfortable by lowering the humidity relative to the carbon dioxide concentration. Therefore, when the evaluation result of comfort is determined to be uncomfortable, the
