Abstract
Description
本発明は、冷凍サイクル装置に備わる膨張弁のリセット制御に関する。 The present invention relates to an expansion valve reset control provided in a refrigeration cycle apparatus.
従来、例えば空気調和機に備わる冷凍サイクル装置において、膨張弁のリセット制御は、運転時における膨張弁の開度を確実に認識可能にするため、運転開始時に膨張弁を一度全閉状態にした後、その後、定められた開度に相当するパルス数で膨張弁を開く。その後、空気調和機では圧縮機の運転が開始される（例えば、特許文献１参照）。 Conventionally, for example, in a refrigeration cycle apparatus provided in an air conditioner, the expansion valve reset control is performed after the expansion valve is once fully closed at the start of operation in order to reliably recognize the opening degree of the expansion valve during operation. Thereafter, the expansion valve is opened with the number of pulses corresponding to the determined opening degree. Thereafter, the operation of the compressor is started in the air conditioner (see, for example, Patent Document 1).
図５は、従来の冷凍サイクル装置における膨張弁のリセット制御を示すタイムチャートである。図５において、冷凍サイクル装置は、前回の運転停止時における膨張弁の開度を記憶しており、運転開始時に、その記憶した膨張弁の開度に基づき膨張弁のリセットを実施する。このリセットにおいては、前回の運転停止時における膨張弁の開度＋αに相当するパルス数で膨張弁が絞られる。その後、定められた開度に相当するパルス数で膨張弁を開けた後に、圧縮機の運転が開始される。ここで、このαは、膨張弁の駆動中に、膨張弁のステッピングモータの脱調等による駆動開度と実開度のズレ分の最大値に相当する。 FIG. 5 is a time chart showing expansion valve reset control in a conventional refrigeration cycle apparatus. In FIG. 5, the refrigeration cycle apparatus stores the opening degree of the expansion valve at the time of the previous operation stop, and resets the expansion valve based on the stored opening degree of the expansion valve at the start of operation. In this reset, the expansion valve is throttled by the number of pulses corresponding to the opening degree + α of the expansion valve at the previous stoppage of operation. Thereafter, after opening the expansion valve with the number of pulses corresponding to the determined opening, the operation of the compressor is started. Here, α corresponds to the maximum value of the difference between the drive opening and the actual opening due to the stepping motor stepping out of the expansion valve during the operation of the expansion valve.
しかしながら、従来の冷凍サイクル装置においては、膨張弁のリセット制御は、空気調和機の運転開始時に実行しなければならない。従って、前回の運転停止時における膨張弁の開度によっては、膨張弁のリセット制御に長い時間が必要となる。この場合、圧縮機の運転をなかなか開始できないという問題点があった。この問題点により、例えば、ユーザが空気調和機の運転開始ボタンを操作してから、空調空気（冷風や暖風）が空調空間に出てくるまでに長時間かかっていた。 However, in the conventional refrigeration cycle apparatus, the reset control of the expansion valve must be executed at the start of operation of the air conditioner. Therefore, depending on the opening of the expansion valve at the time of the previous operation stop, a long time is required for reset control of the expansion valve. In this case, there is a problem that the operation of the compressor cannot be easily started. Due to this problem, for example, it took a long time for the conditioned air (cold air or warm air) to enter the conditioned space after the user operated the operation start button of the air conditioner.
それ故に、本発明は、圧縮機をより早く運転させることが可能な膨張弁リセットを実行可能な冷凍サイクル装置を提供することを目的とする。 Therefore, an object of the present invention is to provide a refrigeration cycle apparatus capable of executing an expansion valve reset capable of operating a compressor earlier.
上記目的を達成するために、本発明は、少なくとも圧縮機と膨張弁とを具備した冷凍サイクル装置であって、前回の運転停止時に、膨張弁のリセット動作を完了させるリセット動作部と、今回の運転開始時に、膨張弁の所定開度に相当するパルス数で膨張弁の開度を調整した後、圧縮機の運転を開始させる運転開始部とを備えている。 In order to achieve the above object, the present invention is a refrigeration cycle apparatus including at least a compressor and an expansion valve, and a reset operation unit for completing a reset operation of the expansion valve at the time of the previous operation stop, And an operation start unit for starting the operation of the compressor after adjusting the opening of the expansion valve by the number of pulses corresponding to the predetermined opening of the expansion valve.
本発明によれば、前回の運転停止時に膨張弁のリセット動作が実施されるため、今回の運転開始時においては、膨張弁を所定開度にするだけで、圧縮機の運転を開始させることが可能となる。これによって、従来よりも圧縮機の立ち上がり時間を短くすることが可能となる。言い換えると、立ち上がり性能を改善可能な冷凍サイクル装置を提供することが可能となる。 According to the present invention, since the expansion valve is reset when the previous operation is stopped, the compressor can be started only by setting the expansion valve to a predetermined opening at the start of the current operation. It becomes possible. This makes it possible to shorten the rise time of the compressor as compared with the conventional case. In other words, it is possible to provide a refrigeration cycle apparatus that can improve the rising performance.
本発明は、少なくとも圧縮機と膨張弁とを具備した冷凍サイクル装置において、前回の運転停止時に、膨張弁のリセット動作を完了させるリセット動作部と、今回の運転開始時に、膨張弁の所定開度に相当するパルス数で膨張弁の開度を調整した後、圧縮機の運転を開始させる運転開始部とを備える。本発明によれば、前回の運転停止時に膨張弁のリセット動作が実施されるため、今回の運転開始時においては、膨張弁を所定開度にするだけで、圧縮機の運転を開始させることが可能となる。これによって、立ち上がり性能を改善可能な冷凍サイクル装置を提供することが可能となる。 The present invention relates to a refrigeration cycle apparatus including at least a compressor and an expansion valve, a reset operation unit that completes a reset operation of the expansion valve when the previous operation was stopped, and a predetermined opening of the expansion valve at the start of the current operation And an operation start unit for starting the operation of the compressor after adjusting the opening degree of the expansion valve by the number of pulses corresponding to. According to the present invention, since the expansion valve is reset when the previous operation is stopped, the compressor can be started only by setting the expansion valve to a predetermined opening at the start of the current operation. It becomes possible. This makes it possible to provide a refrigeration cycle apparatus that can improve the rising performance.
具体的には、リセット動作部は、前回の運転停止時に、膨張弁の全開状態に相当するパルス数以上で膨張弁を絞って閉じることでリセット動作を完了させ、運転開始部は、今回の運転開始時に、膨張弁の所定開度に相当するパルス数で膨張弁を開き、その後、圧縮機の運転を開始させる。 Specifically, the reset operation unit completes the reset operation by closing and closing the expansion valve with the number of pulses corresponding to the fully opened state of the expansion valve when the previous operation stop, and the operation start unit At the start, the expansion valve is opened with the number of pulses corresponding to the predetermined opening of the expansion valve, and then the operation of the compressor is started.
代替的に、リセット動作部は、前回の運転停止時に、膨張弁の全開状態に相当するパルス数以上で膨張弁を絞って閉じた直後に、膨張弁の全開状態に相当するパルス数以上で膨張弁を開くことでリセット動作を完了させ、運転開始部は、今回の運転開始時に、膨張弁の所定開度に相当するパルス数で膨張弁を開き、その後、圧縮機の運転を開始させる。 Alternatively, the reset operation unit expands at the number of pulses corresponding to the fully open state of the expansion valve immediately after closing the expansion valve after closing the expansion valve with the number of pulses corresponding to the fully open state of the expansion valve or not when the previous operation was stopped. The reset operation is completed by opening the valve, and the operation start unit opens the expansion valve with the number of pulses corresponding to the predetermined opening of the expansion valve at the start of the current operation, and then starts the operation of the compressor.
冷凍サイクル装置は、好ましくは、リセット動作が完了したことを示す情報を記憶する記憶部とさらに備える。運転開始部は、今回の運転開始時に、記憶部に情報が格納されている場合、運転開始時部は、膨張弁の所定開度に相当するパルス数で膨張弁の開度を調整した後、圧縮機の運転を開始させ、今回の運転開始時に、記憶部に情報が格納されていない場合、膨張弁のリセット動作を完了させた後、膨張弁の所定開度に相当するパルス数で膨張弁の開度を調整した後、圧縮機の運転を開始させる。これにより、何らかの事情で、冷凍サイクルの運転停止までに電力供給が遮断された場合であっても、リセット動作が完了したことを示す情報が記憶されているため、この情報有無に基づき、膨張弁が正しい開度にされた状態で圧縮機の運転を開始することが可能となる。 The refrigeration cycle apparatus preferably further includes a storage unit that stores information indicating that the reset operation has been completed. When the operation start unit is information stored in the storage unit at the start of the current operation, the operation start unit adjusts the opening of the expansion valve by the number of pulses corresponding to the predetermined opening of the expansion valve, When the compressor is started and no information is stored in the memory at the start of the current operation, the expansion valve reset operation is completed and then the expansion valve is operated with the number of pulses corresponding to the predetermined opening of the expansion valve. After adjusting the opening of the compressor, the operation of the compressor is started. As a result, even if the power supply is interrupted before the refrigeration cycle is stopped for some reason, information indicating that the reset operation has been completed is stored. Based on the presence or absence of this information, the expansion valve It becomes possible to start the operation of the compressor in a state in which is set to the correct opening.
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。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
一般家庭で使用される空気調和機は、通常冷媒配管で互いに接続された室外機と室内機とで構成されており、図１は、本発明に係る空気調和機に備わる冷凍サイクル装置を示す模式図である。 An air conditioner used in a general home is composed of an outdoor unit and an indoor unit that are usually connected to each other through refrigerant pipes. FIG. 1 is a schematic diagram showing a refrigeration cycle apparatus provided in the air conditioner according to the present invention. FIG.
図１において、空気調和機の冷凍サイクル装置は、大略的には、冷媒を圧縮する圧縮機１と、冷房運転と暖房運転とを切り替える四方弁２、室外熱交換器３、絞り機構である電子膨張弁４、及び、室内熱交換器５を備えている。また、電子膨張弁４のリセット動作を制御するため、冷凍サイクル装置には、ステッピングモータ６と、マイコン７と、記憶部８とを備えている。 In FIG. 1, a refrigeration cycle apparatus for an air conditioner generally includes a compressor 1 that compresses a refrigerant, a four-way valve 2 that switches between a cooling operation and a heating operation, an outdoor heat exchanger 3, and an electronic throttle mechanism. An expansion valve 4 and an indoor heat exchanger 5 are provided. In order to control the reset operation of the electronic expansion valve 4, the refrigeration cycle apparatus includes a stepping motor 6, a microcomputer 7, and a storage unit 8.
以上の冷凍サイクル装置における電子膨張弁４のリセットの制御方法について、以下その動作、作用を説明する。 About the control method of reset of the electronic expansion valve 4 in the above refrigeration cycle apparatus, the operation | movement and an effect | action are demonstrated below.
図２は、電子膨張弁４のリセット制御手順を示すフローチャートである。 FIG. 2 is a flowchart showing a reset control procedure of the electronic expansion valve 4.
空気調和機の運転中（ＳＴ０）、リモコンに備わる運転停止ボタンをユーザが操作するなどすると、リモコンからは、空気調和機の運転停止のための信号（以下、運転停止信号）が送出される。この運転停止信号は、空気調和機において、マイコン７により受信される（ＳＴ１）。この運転停止信号に応答して、マイコン７は、圧縮機１を停止する（ＳＴ２）。 During operation of the air conditioner (ST0), when the user operates an operation stop button provided on the remote control, a signal for stopping the operation of the air conditioner (hereinafter referred to as an operation stop signal) is transmitted from the remote control. This operation stop signal is received by the microcomputer 7 in the air conditioner (ST1). In response to this operation stop signal, the microcomputer 7 stops the compressor 1 (ST2).
なお、空気調和機の運転中、マイコン７は、その状況に応じた所望の冷凍サイクルを実現するよう、空気調和機に備わる各種温度センサ（図示せず）により検知された温度から、電子膨張弁４の開度を算出し、電子膨張弁４の開度をステッピングモータ６を介して調整している。その際、電子膨張弁４を駆動しているステッピングモータ６の脱調などの理由により、マイコン７が認識している電子膨張弁４の開度と、実際の開度とにズレが発生している可能性がある。そこで、次回の空気調和機の運転に備え、マイコン７は、電子膨張弁４のリセット動作を実施する（ＳＴ３）。ここで、リセット動作については複数の手法があるため、それらの詳細については後で詳しく説明する。 During the operation of the air conditioner, the microcomputer 7 detects the electronic expansion valve from the temperature detected by various temperature sensors (not shown) provided in the air conditioner so as to realize a desired refrigeration cycle according to the situation. 4 is calculated and the opening of the electronic expansion valve 4 is adjusted via the stepping motor 6. At this time, there is a difference between the opening degree of the electronic expansion valve 4 recognized by the microcomputer 7 and the actual opening degree due to the step-out of the stepping motor 6 driving the electronic expansion valve 4. There is a possibility. Therefore, in preparation for the next operation of the air conditioner, the microcomputer 7 performs a reset operation of the electronic expansion valve 4 (ST3). Here, since there are a plurality of methods for the reset operation, the details thereof will be described in detail later.
電子膨張弁４のリセット動作が完了すると、リセット動作が完了したことを示す情報（フラグ）を、マイコン７は記憶部８に記憶する（ＳＴ４）。なお、空気調和機の停止前にブレーカーが落ちたりすることや停電したりする等の理由で電力供給が途絶えたとき、マイコン７はフラグを記憶部８に記憶できない。 When the reset operation of the electronic expansion valve 4 is completed, the microcomputer 7 stores information (flag) indicating that the reset operation is completed in the storage unit 8 (ST4). Note that the microcomputer 7 cannot store the flag in the storage unit 8 when the power supply is interrupted due to the breaker dropping or power failure before the air conditioner stops.
ＳＴ４の後、マイコン４は、電力供給をオフし空気調和機を停止する（ＳＴ５）。なお、記憶部８は不揮発性メモリであり、電力供給がオフされた場合においても、記憶部８にフラグは記憶され続ける。 After ST4, the microcomputer 4 turns off the power supply and stops the air conditioner (ST5). The storage unit 8 is a non-volatile memory, and the flag is continuously stored in the storage unit 8 even when the power supply is turned off.
さて、ユーザがリモコンに備わる運転開始ボタンを操作すると、リモコンからは、空気調和機の運転開始のための信号（以下、運転開始信号という）が空気調和機に送信される。この運転開始信号は、空気調和機において、マイコン７により受信される（ＳＴ６）。運転開始信号の受信に応答して、マイコン７は、記憶部８にアクセスして、フラグが格納されているか否かを判断する（ＳＴ７）。 When the user operates an operation start button provided on the remote control, a signal for starting the operation of the air conditioner (hereinafter referred to as an operation start signal) is transmitted from the remote control to the air conditioner. This operation start signal is received by the microcomputer 7 in the air conditioner (ST6). In response to receiving the operation start signal, the microcomputer 7 accesses the storage unit 8 and determines whether or not a flag is stored (ST7).
ＳＴ７においてＮｏと判断した場合、マイコン７は、電子膨張弁４のリセット動作を実施する（ＳＴ９）。 If it is determined No in ST7, the microcomputer 7 performs a reset operation of the electronic expansion valve 4 (ST9).
それに対し、ＳＴ７でＹｅｓと判断した場合、マイコン７は、記憶部８からフラグをクリアする（ＳＴ８）。その後、マイコン７は、定められた開度に相当するパルス数で膨張弁を開く。その後、空気調和機では圧縮機の運転が開始する（ＳＴ１０）。これにより、確実に電子膨張弁４のリセットを実施し、マイコン７が認識している電子膨張弁４の開度と実際の電子膨張弁４の開度とのズレを解消することが可能となる。 On the other hand, when it is determined Yes in ST7, the microcomputer 7 clears the flag from the storage unit 8 (ST8). Thereafter, the microcomputer 7 opens the expansion valve with the number of pulses corresponding to the determined opening. Thereafter, in the air conditioner, the operation of the compressor is started (ST10). As a result, the electronic expansion valve 4 can be reliably reset, and the deviation between the opening degree of the electronic expansion valve 4 recognized by the microcomputer 7 and the actual opening degree of the electronic expansion valve 4 can be eliminated. .
以上説明したように、本冷凍サイクル装置によれば、前回の運転停止時に電子膨張弁４のリセット動作が実施されるため、今回の運転開始時においては、電子膨張弁４を所定開度にするだけで、圧縮機１の運転を開始させることが可能となる。これによって、従来よりも圧縮機の立ち上がり時間を短くすることが可能となる。言い換えると、立ち上がり性能を改善可能な冷凍サイクル装置を提供することが可能となる。 As described above, according to the present refrigeration cycle apparatus, the reset operation of the electronic expansion valve 4 is performed when the previous operation is stopped. Therefore, the electronic expansion valve 4 is set to a predetermined opening at the start of the current operation. Only by this, the operation of the compressor 1 can be started. This makes it possible to shorten the rise time of the compressor as compared with the conventional case. In other words, it is possible to provide a refrigeration cycle apparatus that can improve the rising performance.
ここで、リセット動作について２つの具体例を説明する。 Here, two specific examples of the reset operation will be described.
図３は、電子膨張弁４のリセット制御の一例を示すタイミングチャートである。図２の
ＳＴ２の後、電子膨張弁４は、最大開度Ａ＋αに相当するパルス数で、ステッピングモータ６により駆動され、絞られる。これにより、電子膨張弁４は全閉状態となり、空気調和機の運転を停止する。このαパルスは電子膨張弁４の駆動中に、ステッピングモータ６の脱調等による駆動開度と実開度のズレを考慮したものである。そして、ＳＴ６において運転開始信号を受信し、この時フラグが記憶されていると、定められた開度に相当するパルス数で電子膨張弁４の開度を調整し、その後、圧縮機１の運転を開始することにより、ユーザが運転信号を送信してから実際に圧縮機が運転するまでの時間を短縮することが可能となる。
FIG. 3 is a timing chart showing an example of reset control of the electronic expansion valve 4. After ST2 in FIG. 2, the electronic expansion valve 4 is driven and throttled by the stepping motor 6 with the number of pulses corresponding to the maximum opening A + α. As a result, the electronic expansion valve 4 is fully closed, and the operation of the air conditioner is stopped. This α pulse takes into account the deviation between the driving opening and the actual opening due to the step-out of the stepping motor 6 while the electronic expansion valve 4 is being driven. When the operation start signal is received in ST6 and the flag is stored at this time, the opening of the electronic expansion valve 4 is adjusted by the number of pulses corresponding to the determined opening, and then the operation of the compressor 1 is performed. By starting the operation, it is possible to shorten the time from when the user transmits the operation signal to when the compressor is actually operated.
また、図４は、電子膨張弁４のリセット制御の他の例を示すタイミングチャートである。図２のＳＴ２の後、電子膨張弁４は、最大開度Ａ＋αに相当するパルス数で絞られる。その後、電子膨張弁４の最大開度Ａに相当するパルス数で電子膨張弁４は開かれ、これによって、電子膨張弁４は全開状態となる。この状態で、空気調和機は運転停止する。そして、ＳＴ６において運転開始信号を受信し、この時フラグが記憶されていると、マイコン７は、定められた開度に電子膨張弁４を調整し、圧縮機１の運転を開始する。これにより、リモコンが運転開始信号を送信してから実際に圧縮機が運転するまでの時間を短縮することが可能となると共に、空気調和機の停止時に、仮に電子膨張弁４の固着などが発生した場合にも、次回空気調和機運転時に膨張弁は全開状態となる。以上のように、本例によれば、電子膨張弁４のリセット完了後のパルスを全開パルスとして、空気調和機の運転停止することで、停止時に仮に膨張弁の固着などが発生した場合にも冷凍サイクルの閉塞を回避することが可能となり、各種冷凍サイクル部品を保護することが可能となる。 FIG. 4 is a timing chart showing another example of reset control of the electronic expansion valve 4. After ST2 in FIG. 2, the electronic expansion valve 4 is throttled by the number of pulses corresponding to the maximum opening A + α. Thereafter, the electronic expansion valve 4 is opened with the number of pulses corresponding to the maximum opening A of the electronic expansion valve 4, whereby the electronic expansion valve 4 is fully opened. In this state, the air conditioner stops operating. In ST6, when the operation start signal is received and the flag is stored at this time, the microcomputer 7 adjusts the electronic expansion valve 4 to a predetermined opening and starts the operation of the compressor 1. As a result, it is possible to shorten the time from when the remote controller transmits the operation start signal to when the compressor is actually operated, and when the air conditioner is stopped, the electronic expansion valve 4 is temporarily fixed. In this case, the expansion valve is fully opened when the air conditioner is operated next time. As described above, according to this example, the pulse after completion of resetting of the electronic expansion valve 4 is set as a full-open pulse, and the operation of the air conditioner is stopped. It is possible to avoid clogging of the refrigeration cycle, and it is possible to protect various refrigeration cycle components.
本発明に係る冷凍サイクル装置は、圧縮機をより早く運転させることが可能となり、例えば空気調和機、冷蔵庫に好適である。 The refrigeration cycle apparatus according to the present invention can operate the compressor earlier, and is suitable for an air conditioner and a refrigerator, for example.
