Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 フィルタが目詰まりした場合でも吸込み風量 の減少を抑えることができ、これにより冷凍サイクル機 器への悪影響を解消するとともに、最適温度の空調用空 気を得て快適性が確保できる空気調和機を提供する。 【構成】 室内ファンモータ7Mの回転数Nを検知し、 この検知回転数Nが設定風量に対応する目標回転数Nt となるよう室内ファンモータ7Mへの印加電圧Vdの位 相を制御する。このとき、位相制御値Pが目標回転数N tを得るための基準位相値αを中心とする許容変化幅β 内にあるか否か判定し、許容変化幅β内にあれば検知回 転数Nに基づく回転数フィードバック位相制御を続行す る。ただし、位相制御値Pが許容変化幅βから外れてい る場合には、位相制御値Pを許容変化幅βの限度値にシ フトして回転数Nの低下を防ぐ。 (57) [Abstract] [Purpose] Even if the filter is clogged, it is possible to suppress the reduction of the intake air volume, thereby eliminating the adverse effect on the refrigeration cycle equipment and obtaining the air-conditioning air at the optimum temperature for comfort. To provide an air conditioner that can secure [Structure] Detecting the rotation speed N of the indoor fan motor 7M, This detected rotation speed N is the target rotation speed Nt corresponding to the set air volume. The phase of the voltage Vd applied to the indoor fan motor 7M is controlled so that At this time, the phase control value P is equal to the target rotation speed N. Allowable variation range β around the reference phase value α for obtaining t If it is within the allowable change width β, the rotation speed feedback phase control based on the detected rotation speed N is continued. However, when the phase control value P deviates from the allowable change width β, the phase control value P is shifted to the limit value of the allowable change width β to prevent the rotation speed N from decreasing.
