Description

本発明は、誤アドレス検知制御を搭載した空気調和装置に関するものである。 The present invention relates to an air conditioner equipped with erroneous address detection control.

従来の空気調和装置におけるアドレス設定方法は、図５の動作フローチャートに示すように、室内側熱交換器の温度と低圧飽和温度との比較から冷媒の流れを検知し、室内機と室外機の冷媒系統の対応関係を判定し自動的に冷媒系統アドレスを割り付けるものが一般的である（例えば、特許文献１参照）。
特開２００３−９０５８５号公報 As shown in the operation flowchart of FIG. 5, the address setting method in the conventional air conditioner detects the refrigerant flow from the comparison between the temperature of the indoor heat exchanger and the low pressure saturation temperature, and the refrigerant of the indoor unit and the outdoor unit. It is common to determine the correspondence of the system and automatically assign the refrigerant system address (see, for example, Patent Document 1).
JP 2003-90585 A

しかしながら、このような多くの系統が併設された空気調和システムの場合、室外機から室内機までの配管長さや季節によっては、冷媒が流れていても室内側熱交換器の温度と低圧飽和温度に顕著な差が生じず、誤った冷媒系統アドレス設定がなされるケースがあった。   However, in the case of an air conditioning system with many such systems, depending on the length of the pipe from the outdoor unit to the indoor unit and the season, the temperature of the indoor heat exchanger and the low-pressure saturation temperature may vary even if the refrigerant is flowing. There was a case where the refrigerant system address was incorrectly set without noticeable difference.

本発明は、上記従来の課題を解決するもので、たとえ対応する室外機のアドレス設定を誤った場合でも、冷媒系統ごとの試運転時に各々の室内機の熱交換器温度変化からアドレス設定を誤った室内機を割り出し、正しいアドレス設定に再登録することができる制御の提供を目的とする。   The present invention solves the above-described conventional problems, and even when the address setting of the corresponding outdoor unit is wrong, the address setting is wrong from the heat exchanger temperature change of each indoor unit during the trial operation for each refrigerant system. The purpose is to provide a control that can identify indoor units and re-register them with correct address settings.

上記課題を解決する為に本発明は、冷媒系統ごとの試運転時に、例えば冷房試運転の場合は室内機熱交換器温度センサが検出した熱交換器温度Ｔｅ１が運転前に検出した熱交換器温度Ｔｅ０に対し所定の温度差以内、すなわちＴｅ０−Ｔｅ１＜αであった場合、該室内機制御装置は対応室外機アドレス設定を誤ったとして異常信号を出力するもので、この構成をなすことによりアドレス設定を誤った室内機を割り出すことが可能となる。   In order to solve the above-described problems, the present invention provides a heat exchanger temperature Te0 detected before the operation by the heat exchanger temperature Te1 detected by the indoor unit heat exchanger temperature sensor in the case of a trial operation for each refrigerant system, for example, in the case of a cooling trial operation. If the temperature difference is within a predetermined temperature range, that is, Te0−Te1 <α, the indoor unit control device outputs an abnormal signal because the corresponding outdoor unit address setting is incorrect. It is possible to determine the wrong indoor unit.

以上のように本発明の誤アドレス検知制御は、多くの冷媒系統が併設された空気調和システムにおいて、室内機の対応する室外機アドレス設定を誤った場合でも、冷媒系統ごとの試運転時に、例えば冷房試運転の場合は室内機熱交換器温度センサが検出した熱交換器温度Ｔｅ１が運転前に検出した熱交換器温度Ｔｅ０に対し所定の温度差以内、すなわちＴｅ０−Ｔｅ１＜αであった場合、該室内機制御装置は対応室外機アドレス設定を誤ったとして異常信号を出力することにより、アドレス設定を誤った室内機を割り出すことができる。   As described above, the erroneous address detection control according to the present invention is an air conditioning system in which a large number of refrigerant systems are provided. Even when the corresponding outdoor unit address setting of the indoor unit is erroneous, during the trial operation for each refrigerant system, for example, cooling In the case of the trial operation, if the heat exchanger temperature Te1 detected by the indoor unit heat exchanger temperature sensor is within a predetermined temperature difference with respect to the heat exchanger temperature Te0 detected before the operation, that is, Te0−Te1 <α, The indoor unit control device can determine the indoor unit with the wrong address setting by outputting an abnormal signal when the corresponding outdoor unit address setting is incorrect.

When -Te1 <α, the indoor unit control device can determine the indoor unit with the wrong address setting by outputting an abnormal signal with the corresponding outdoor unit address setting being incorrect.

When the temperature difference is within a predetermined temperature difference with respect to the temperature Ta, that is, Ta−Te1 <α, the indoor unit control device outputs an abnormal signal indicating that the corresponding outdoor unit address setting is incorrect, thereby causing the room setting with the incorrect address setting.

On the other hand, if the temperature difference is within a predetermined temperature difference, that is, if Tc1−Tc0 <α, the indoor unit control device outputs an abnormal signal indicating that the corresponding outdoor unit address setting is incorrect, thereby determining the indoor unit with the wrong address setting. be able to.
