従来、この種の空気調和機は室外熱交温度センサによる室外熱交換器温度から外気温度を推定して運転制御を行なっている（例えば、特許文献１参照）。   Conventionally, this type of air conditioner performs operation control by estimating the outdoor air temperature from the outdoor heat exchanger temperature by an outdoor heat exchanger temperature sensor (see, for example, Patent Document 1).

しかしながら、前記従来の方法では、運転停止から室外熱交換器温度が外気温度に近づ
くまでに長時間必要とするので、前の運転時の外気温度をそのまま流用しており、外気温度が変化しても外気温度を再推定して更新することができないという課題を有していた。 However, since the conventional method requires a long time from when the operation is stopped until the outdoor heat exchanger temperature approaches the outside air temperature, the outside air temperature during the previous operation is used as it is, and the outside air temperature changes. However, there was a problem that the outside temperature could not be reestimated and updated.

本発明は、前記従来の課題を解決するもので、外気温度センサを使用せずに、圧縮機起動の際には毎回外気温度を更新することを可能とした空気調和機を提供することを目的とする。   SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object thereof is to provide an air conditioner that can update the outside air temperature every time the compressor is started without using an outside air temperature sensor. And

前記従来の課題を解決するために、本発明の空気調和機は、圧縮機と、室外熱交換器と、室外ファンと、室外熱交換器の温度を検出する室外熱交換器温度検出手段とを備え、圧縮機が停止している時に、室外ファンを所定時間運転することによって室外熱交換器温度検出手段より得られた室外熱交換器の温度から、圧縮機運転中の外気温度を推定する空気調和機であって、冷房運転から暖房運転、もしくは暖房運転から冷房運転へ切り替わる時に圧縮機が停止する際は、室外熱交換器温度検出手段で検出される室外熱交換器の温度に基づいて、外気温度を推定しないものである。 In order to solve the above-mentioned conventional problems, an air conditioner of the present invention includes a compressor, an outdoor heat exchanger, an outdoor fan, and an outdoor heat exchanger temperature detecting means for detecting the temperature of the outdoor heat exchanger. Air that estimates the outdoor air temperature during compressor operation from the temperature of the outdoor heat exchanger obtained from the outdoor heat exchanger temperature detection means by operating the outdoor fan for a predetermined time when the compressor is stopped When the compressor is stopped when the cooling operation is switched from the cooling operation to the heating operation or from the heating operation to the cooling operation, based on the temperature of the outdoor heat exchanger detected by the outdoor heat exchanger temperature detecting means, The outside air temperature is not estimated .

これによって、外気温度の誤検知を防ぐことが可能となる。 This makes it possible to prevent erroneous detection of the outside air temperature.

本発明の空気調和機は、外気温度センサを使用せずに、従来より更に検知精度をあげた外気温度の推定ができるので、ユーザ環境の快適さを保ちながら、センサ、ホルダ、電装品を含む部品コストの削減が可能となる。また、複雑な計算式を使用していない為にソフトの簡素化が可能となり、他機種とのソフトの共用化が図れるので、設計コストや部品コストの削減が可能となる。   Since the air conditioner of the present invention can estimate the outside air temperature with higher detection accuracy than the conventional one without using the outside air temperature sensor, it includes a sensor, a holder, and electrical components while maintaining the comfort of the user environment. Parts cost can be reduced. In addition, since a complicated calculation formula is not used, software can be simplified, and software can be shared with other models, so that design costs and component costs can be reduced.

第１の発明は、圧縮機と、室外熱交換器と、室外ファンと、室外熱交換器の温度を検出する室外熱交換器温度検出手段とを備え、圧縮機が停止している時に、室外ファンを所定時間運転することによって室外熱交換器温度検出手段より得られた室外熱交換器の温度から、圧縮機運転中の外気温度を推定する空気調和機であって、冷房運転から暖房運転、もしくは暖房運転から冷房運転へ切り替わる時に圧縮機が停止する際は、室外熱交換器温度検出手段で検出される室外熱交換器の温度に基づいて、外気温度を推定しないものであり、これによって、外気温度の誤検知を防ぐことができる。 The first invention comprises a compressor, an outdoor heat exchanger, an outdoor fan, and an outdoor heat exchanger temperature detecting means for detecting the temperature of the outdoor heat exchanger, and when the compressor is stopped, An air conditioner that estimates the outside air temperature during compressor operation from the temperature of the outdoor heat exchanger obtained from the outdoor heat exchanger temperature detection means by operating the fan for a predetermined time, and from the cooling operation to the heating operation, Alternatively, when the compressor is stopped when switching from heating operation to cooling operation, the outdoor air temperature is not estimated based on the temperature of the outdoor heat exchanger detected by the outdoor heat exchanger temperature detection means. False detection of the outside air temperature can be prevented.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

FIG. 4 is a conceptual diagram of the time-dependent change of the outdoor heat exchanger temperature during operation, FIG. 4 is a correlation diagram of the rate of change of the outdoor heat exchanger temperature, the difference between the outdoor air temperature and the outdoor heat exchanger temperature, and FIG.

図１において、ＳＴ０１で、圧縮機起動前に室外ファンを所定時間（Ｔａ）運転する。その後、ＳＴ０２において室外熱交換器温度から推定される外気温度Ｔｏｕｔの更新を行なう。
次に、空気調和機の運転モードによってフローが分岐する。暖房運転（ＳＴ１１）の場合、ＳＴ１２で直前の推定外気温度Ｔｏｕｔが所定温度Ｔｃ以上であれば、ＳＴ１３へ進み
、推定外気温度Ｔｏｕｔに所定の補正値ΔＴ１を加えてＳＴ３１へ進む。
冷房運転（ＳＴ２１）の場合、ＳＴ２２で直前の推定外気温度Ｔｏｕｔが所定温度Ｔｄ以下であれば、ＳＴ２３へ進み、推定外気温度Ｔｏｕｔに所定の補正値ΔＴ２を加えてＳＴ３１へ進む。
それぞれのステップで条件を充たさない場合は、推定外気温度Ｔｏｕｔに補正値を加えず、ＳＴ３１へ進む。
ＳＴ３１で、室外熱交換器温度の温度変化率ΔＴｏｕｔ／Δｔが大きい場合には、ＳＴ３２へ進み、推定外気温度Ｔｏｕｔに補正値ΔＴ３を加え、小さい場合には、推定外気温度Ｔｏｕｔには補正値を加えず、ＳＴ０３に進む。
以上のようなフローで外気温度Ｔｏｕｔを推定し、その条件を加味してＳＴ０３で最適な運転条件にて圧縮機運転を開始（再開）し、ＳＴ０４に進む。 In FIG. 1, in ST01, the outdoor fan is operated for a predetermined time (Ta) before the compressor is started. Thereafter, the outdoor temperature Tout estimated from the outdoor heat exchanger temperature is updated in ST02.
Next, the flow branches depending on the operation mode of the air conditioner. In the heating operation (ST11), if the immediately preceding estimated outside air temperature Tout is equal to or higher than the predetermined temperature Tc in ST12, the process proceeds to ST13, a predetermined correction value ΔT1 is added to the estimated outside air temperature Tout, and the process proceeds to ST31.
In the cooling operation (ST21), if the previous estimated outside air temperature Tout is equal to or lower than the predetermined temperature Td in ST22, the process proceeds to ST23, and a predetermined correction value ΔT2 is added to the estimated outside air temperature Tout, and the process proceeds to ST31.
When the condition is not satisfied in each step, the correction value is not added to the estimated outside air temperature Tout, and the process proceeds to ST31.
In ST31, when the temperature change rate ΔTout / Δt of the outdoor heat exchanger temperature is large, the process proceeds to ST32, and the correction value ΔT3 is added to the estimated outside air temperature Tout. Without adding, proceed to ST03.
The outside air temperature Tout is estimated by the flow as described above, and the compressor operation is started (restarted) under the optimum operation condition in ST03 taking the condition into consideration, and the process proceeds to ST04.

ＳＴ０４で、圧縮機が停止しているかどうか確認し、圧縮機が停止していなければＳＴ０５で圧縮機の連続運転時間がｔｃに達した場合、ＳＴ０６へと進み、圧縮機を強制停止し、ＳＴ０７で均圧促進のために室外ファンを所定時間（ｔｂ）運転する。
ｔｃ以前に圧縮機が停止した場合（ＳＴ０４）には、ＳＴ４１へ移行する。 In ST04, it is confirmed whether or not the compressor is stopped. If the compressor has not stopped, if the continuous operation time of the compressor reaches tc in ST05, the process proceeds to ST06 and the compressor is forcibly stopped. ST07 Then, the outdoor fan is operated for a predetermined time (tb) to promote pressure equalization.
If the compressor stops before tc (ST04), the process proceeds to ST41.

ＳＴ４１では、圧縮機の停止がモード変更によるものであった場合には、圧縮機停止とはみなさず、再びＳＴ０３へ戻る。圧縮機の停止が、モード変更によるものでない場合、ＳＴ５１で圧縮機起動からの時間を判定し、所定時間（ｔｄ）未満であれば、圧縮機停止とはみなさず、再びＳＴ０３へ戻る。それ以外はＳＴ０７へ移行し、均圧促進のために室外ファンを所定時間（ｔｂ）運転する。   In ST41, when the stop of the compressor is due to the mode change, the compressor is not regarded as being stopped, and the process returns to ST03 again. When the stop of the compressor is not due to the mode change, the time from the start of the compressor is determined in ST51, and if it is less than the predetermined time (td), the compressor is not regarded as being stopped and the process returns to ST03 again. Otherwise, the process proceeds to ST07, and the outdoor fan is operated for a predetermined time (tb) to promote equalization.

ＳＴ０７では、均圧促進のために室外ファンをｔｂ間運転させた後、空気調和機の運転が続いている場合は、再びＳＴ０１に戻り、状況に応じて推定外気温度Ｔｏｕｔを更新する。   In ST07, after operating the outdoor fan for tb to promote pressure equalization, if the operation of the air conditioner continues, the process returns to ST01, and the estimated outside air temperature Tout is updated according to the situation.

尚、本実施の形態では、室外熱交換器温度が外気温度Ｔｏｕｔと同値と推定する手法を採用している。   In the present embodiment, a method is employed in which the outdoor heat exchanger temperature is estimated to be equal to the outdoor air temperature Tout.

図２は、暖房運転時に外気温度がＴｃ以上の場合、室外ファン運転時の室外熱交換器温度の変化を示すものである。暖房運転時には室外熱交換器の温度が下がる為、外気温度と室外熱交換器温度が大きく乖離しているが、圧縮機停止後に室外ファンを運転することによって、外気温度と室外熱交換器温度が近似する。しかし、途中段階では実際の外気温度に対して値が上下に振動する。そこで、室外ファン運転終了時の室外熱交換器温度即ち、推定外気温度Ｔｏｕｔに所定の補正値（ΔＴ１）を加える補正を行なうことによって、より実際の外気温度に近い値を得るものである。   FIG. 2 shows a change in outdoor heat exchanger temperature during outdoor fan operation when the outside air temperature is equal to or higher than Tc during heating operation. Since the temperature of the outdoor heat exchanger decreases during the heating operation, the outdoor air temperature and the outdoor heat exchanger temperature are greatly different from each other. Approximate. However, the value fluctuates up and down with respect to the actual outside air temperature in the middle stage. Therefore, a value closer to the actual outside air temperature is obtained by performing correction by adding a predetermined correction value (ΔT1) to the outdoor heat exchanger temperature at the end of the outdoor fan operation, that is, the estimated outside air temperature Tout.

図３は、冷房運転時に外気温度がＴｄ以下の場合、室外ファン運転時の室外熱交換器温度の変化を示すものである。冷房運転時には室外熱交換器の温度が上がる為、外気温度と室外熱交換器温度が大きく乖離しているが、圧縮機停止後に室外ファンを運転することによって、外気温度と室外熱交換器温度が近似する。しかし、途中段階では実際の外気温度に対して値が上下に振動する。そこで、室外ファン運転終了時の室外熱交換器温度即ち、推定外気温度Ｔｏｕｔに所定の補正値（ΔＴ２）を加える補正を行なうことによって、より実際の外気温度に近い値を得るものである。   FIG. 3 shows a change in outdoor heat exchanger temperature during outdoor fan operation when the outside air temperature is equal to or lower than Td during cooling operation. Since the temperature of the outdoor heat exchanger rises during cooling operation, the outdoor air temperature and the outdoor heat exchanger temperature are greatly different. However, by operating the outdoor fan after the compressor stops, Approximate. However, the value fluctuates up and down with respect to the actual outside air temperature in the middle stage. Therefore, a value closer to the actual outside air temperature is obtained by performing correction by adding a predetermined correction value (ΔT2) to the outdoor heat exchanger temperature at the end of the outdoor fan operation, that is, the estimated outside air temperature Tout.

図４は、圧縮機停止時の室外ファン運転中（ｔｂ）の室外熱交換器温度の変化率ΔＴｏｕｔ／Δｔと実際の外気温度と推定外気温度（室外熱交換器温度）の差ΔＴｏｕｔを示すものである。変化率の大きいほど温度差は大きくなるので、圧縮機運転開始時に室外熱交換器温度即ち、推定外気温度Ｔｏｕｔに所定の補正値（ΔＴ３）を加える補正を行なうこ
とによって、より実際の外気温度に近い値を得るものである。 FIG. 4 shows the change rate ΔTout / Δt of the outdoor heat exchanger temperature during outdoor fan operation (tb) when the compressor is stopped, and the difference ΔTout between the actual outside air temperature and the estimated outside air temperature (outdoor heat exchanger temperature). It is. Since the temperature difference increases as the rate of change increases, by performing a correction that adds a predetermined correction value (ΔT3) to the outdoor heat exchanger temperature, that is, the estimated outside air temperature Tout at the start of compressor operation, the actual outside air temperature is further increased. Get a close value.

図５は、モード変化を伴う圧縮機停止の場合の制御タイムチャートである。Ａでは、冷房から暖房へ切り替えた直後の圧縮機停止なので、圧縮機再起動時に外気温度の更新は行なわず、Ｂでは、暖房運転中圧縮機停止なので、圧縮機再起動時に外気温度の更新を行なう。   FIG. 5 is a control time chart when the compressor is stopped with a mode change. In A, since the compressor is stopped immediately after switching from cooling to heating, the outside temperature is not updated when the compressor is restarted. In B, since the compressor is stopped during the heating operation, the outside temperature is updated when the compressor is restarted. Do.

図６は、圧縮機が連続して停止した場合の制御タイムチャートである。Ａでは、前回圧縮機が停止してから所定時間（ｔｄ）未満であるので、圧縮機再起動時に外気温度の更新は行なわず、Ｂでは、前回圧縮機が停止してから所定時間（ｔｄ）以上であるので、圧縮機再起動時に外気温度の更新を行なう。   FIG. 6 is a control time chart when the compressor is continuously stopped. In A, since it is less than the predetermined time (td) since the previous compressor stop, the outside air temperature is not updated when the compressor is restarted, and in B, the predetermined time (td) since the previous compressor stopped. As described above, the outside air temperature is updated when the compressor is restarted.

以上のように、本実施の形態においては運転モード及び直前の推定外気温度値によって推定外気温度に所定の補正値を加えることにより、外気温度の誤検知を回避し、検知精度を向上させることが可能となり、快適な空調を提供することができる。   As described above, in the present embodiment, by adding a predetermined correction value to the estimated outside air temperature according to the operation mode and the immediately preceding estimated outside air temperature value, erroneous detection of the outside air temperature can be avoided and detection accuracy can be improved. This makes it possible to provide comfortable air conditioning.

This makes it possible to provide comfortable air conditioning.

また、本実施の形態では運転モードの変更を伴ない連続運転を行なう場合、運転モード変化による圧縮機停止は、圧縮機停止とみなさず、推定外気温度の更新を行なわないことにより、圧縮機を強制停止する回数が減り、誤検知なく、快適な空調を提供することができる。   Further, in the present embodiment, when continuous operation is performed with a change in the operation mode, the compressor stop due to the change in the operation mode is not regarded as the compressor stop, and the estimated outside air temperature is not updated, so that the compressor is The number of forced stops is reduced, and comfortable air conditioning can be provided without false detection.

また、本実施の形態では圧縮機運転後一定期間（ｔｄ）内に圧縮機が停止した場合は、圧縮機停止とみなさず、推定外気温度の更新を行なわないことにより、圧縮機を強制停止する回数が減り、誤検知なく、快適な空調を提供することができる。   In the present embodiment, when the compressor stops within a certain period (td) after the compressor is operated, the compressor is forcibly stopped by not updating the estimated outside air temperature without considering the compressor stopped. The number of times is reduced, and comfortable air conditioning can be provided without false detection.
