Description

本発明は、冷房運転時サーモオフ制御を行う空気調和装置に関するものである。   The present invention relates to an air conditioner that performs thermo-off control during cooling operation.

従来、この種の空気調和装置は、室内ユニットと室外ユニットで構成されたセパレート型空気調和装置の構成を持っている(例えば、特許文献1参照)。   Conventionally, this type of air conditioner has a configuration of a separate type air conditioner composed of an indoor unit and an outdoor unit (see, for example, Patent Document 1).

図3は、従来のセパレート型空気調和装置の概略構成図、図4は、従来の室内ユニットの側断面図を示すものである。   FIG. 3 is a schematic configuration diagram of a conventional separate type air conditioner, and FIG. 4 is a side sectional view of a conventional indoor unit.

図3に示すように、セパレート型空気調和装置は、室内ユニット1と室外ユニット2で構成され、室外ユニット2内の圧縮機3で流体を室内ユニット1と室外ユニット2間を循環させる。   As shown in FIG. 3, the separate air conditioner includes an indoor unit 1 and an outdoor unit 2, and circulates fluid between the indoor unit 1 and the outdoor unit 2 by a compressor 3 in the outdoor unit 2.

図4に示すように、この室内ユニット1内部には、空気をA方向の吸込パネル4から吸い込み、熱交換器5により吸い込んだ空気と熱交換器5中を流れる流体を熱交換し、この熱交換された空気を吹出口6からファン7によりB方向に排出する。吹出口6付近にはモータ9にてスイングする上下羽根8が取り付けられている。   As shown in FIG. 4, air is sucked into the indoor unit 1 from the suction panel 4 in the direction A, and the air sucked by the heat exchanger 5 and the fluid flowing in the heat exchanger 5 are heat-exchanged. The exchanged air is discharged from the air outlet 6 by the fan 7 in the B direction. Upper and lower blades 8 that swing by a motor 9 are attached in the vicinity of the air outlet 6.

以上のような空気調和装置が設置された部屋の運転状態について室内ユニット1および室外ユニット2をもちいて、以下その動作、作用を説明する。   The operation and action of the room in which the air conditioner as described above is installed will be described below using the indoor unit 1 and the outdoor unit 2.

冷房運転時に、室内ユニット1内部でA方向から吸い込まれた空気が熱交換器5中の流体で冷やされ除湿してB方向に吹き出される。さらに吹き出された冷風は、スイングする上下羽根8により部屋の隅々まで到達する。そして冷房運転時に、室内ユニット1が設置された部屋の空調が設定温度(リモコンなどより設定)に達すると、室外ユニット2の圧縮機3の運転が停止もしくは低容量で運転して、流体の循環が止まる。これは、いわゆるサーモオフ状態と呼ばれる(以下サーモオフと呼ぶ)。つまり冷房運転時において、部屋の温度が設定温度にまで達すれば圧縮機3が停止もしくは低容量で運転し流体の循環が止まる。部屋の温度が設定温度より上昇すれば、部屋を再度冷やすために圧縮機3が運転して流体が熱交換器5を循環する。空気調和装置は、リモコンの設定温度などにより部屋の温度をあわせるため、このような運転が繰り返されている。
特開平6−26716号公報
During the cooling operation, the air sucked from the A direction inside the indoor unit 1 is cooled by the fluid in the heat exchanger 5, dehumidified, and blown out in the B direction. Further, the blown cold air reaches every corner of the room by the swinging upper and lower blades 8. During the cooling operation, when the air conditioning in the room in which the indoor unit 1 is installed reaches a set temperature (set by a remote controller or the like), the operation of the compressor 3 of the outdoor unit 2 is stopped or operated at a low capacity to circulate the fluid. Stops. This is called a so-called thermo-off state (hereinafter referred to as thermo-off). That is, during the cooling operation, when the room temperature reaches the set temperature, the compressor 3 stops or operates at a low capacity, and the circulation of the fluid stops. When the room temperature rises above the set temperature, the compressor 3 is operated to cool the room again, and the fluid circulates through the heat exchanger 5. Since the air conditioner adjusts the room temperature according to the temperature set by the remote controller or the like, such operation is repeated.
JP-A-6-26716

しかしながら、前記従来の構成では、空気調和装置の冷房運転時におけるサーモオフ状態では、室外ユニットは停止するが、室内ユニットのファンは設定された回転数の状態で運転している。この時、室外ユニットの圧縮機が停止もしくは低容量で運転するため、室内ユニットの熱交換中では吸い込まれた空気と流体との熱交換がなくなり、この吸い込まれた空気が冷やされたり除湿されたりしない状態になる。このために吸い込まれた空気は熱交換器を通過する時に熱交換器に付着した水滴(水分)を含んだ状態になりファンにより部屋に吹き出され、吹き出された水分を含んだ空気により部屋の湿度が大きく上昇し、部屋にいる人は湿度が上昇することにより大変不快になるため、快適性が低下するという課題を有していた。   However, in the conventional configuration, in the thermo-off state during the cooling operation of the air conditioner, the outdoor unit is stopped, but the fan of the indoor unit is operated at the set rotational speed. At this time, since the compressor of the outdoor unit is stopped or operates at a low capacity, heat exchange between the sucked air and the fluid is lost during heat exchange of the indoor unit, and the sucked air is cooled or dehumidified. It will be in a state that does not. For this reason, the sucked air passes through the heat exchanger and contains water droplets (moisture) adhering to the heat exchanger, and is blown out into the room by the fan. The air containing the moisture is blown into the room humidity. However, the person who is in the room becomes very uncomfortable due to the increase in humidity, so that there is a problem that comfort is lowered.

本発明は、前記従来の課題を解決するもので、冷房運転時の圧縮機の運転時間によりフ
ァンの回転数を制御することにより、部屋の湿度上昇を防止して快適性を向上させる空気調和装置を提供することを目的とする。
The present invention solves the above-mentioned conventional problems, and controls the rotational speed of the fan according to the operation time of the compressor during cooling operation, thereby preventing an increase in room humidity and improving comfort. The purpose is to provide.

前記従来の課題を解決するために、本発明の空気調和装置は、室外ユニットに取り付けられた圧縮機において、冷房運転時のサーモオフ中に圧縮機の運転時間により、ファンの回転数を変化させるものである。   In order to solve the above-described conventional problems, an air conditioner according to the present invention is a compressor attached to an outdoor unit that changes the number of rotations of a fan depending on the operation time of the compressor during thermo-off during cooling operation. It is.

これによって、サーモオフ中において熱交換器に付着した水滴(水分)を含んだ空気が部屋に吹き出されるため湿度が大きく上昇していたが、圧縮機の運転時間によりファンの回転数を小さくすることにより水滴(水分)を含んだ空気の放出量を低減することができる。   As a result, the air containing water droplets (moisture) adhering to the heat exchanger is blown out into the room during the thermo-off, and the humidity has increased significantly. Therefore, it is possible to reduce the discharge amount of air containing water droplets (water).

本発明の空気調和装置は、室外ユニットに取り付けられた圧縮機の運転時間により、ファンの回転数を小さくする制御は、サーモオフ中に部屋の湿度を低減し快適性を向上させることができる。   In the air conditioner of the present invention, the control for reducing the rotation speed of the fan according to the operation time of the compressor attached to the outdoor unit can reduce the humidity of the room and improve the comfort during the thermo-off.

第1の発明は室内ユニットに取り付けられたファンの回転数を変化させる制御、つまり圧縮機の運転時間により、ファンの回転数を小さくして湿度の上昇を低減することができる。   According to the first aspect of the present invention, the increase in humidity can be reduced by reducing the number of revolutions of the fan by the control for changing the number of revolutions of the fan attached to the indoor unit, that is, the operation time of the compressor.

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.

(実施の形態1)
本発明の実施の形態における室内ユニットは従来と同様であるため、図4の従来の室内ユニットの側断面図を流用し、設置された部屋の運転状態について、以下その動作、作用を説明する。
(Embodiment 1)
Since the indoor unit in the embodiment of the present invention is the same as the conventional one, the side sectional view of the conventional indoor unit in FIG. 4 is used, and the operation and action of the installed room will be described below.

冷房運転時に、室内ユニット1内部でA方向から吸い込まれた空気が熱交換器5で冷やされ除湿してB方向に吹き出される。吹き出された冷風は、スイングする上下羽根8により部屋の隅々まで到達する。そしてこの部屋の空調が設定温度(リモコンなどにて設定)に達すると、室外ユニット2の運転が停止する。すなわち、室外ユニット2に設置された流体を循環させる装置である圧縮機3が停止する。これらサーモオフ状態において、圧縮機の運転時間により、ファン13の回転数を変化させる動作を行う。   During the cooling operation, the air sucked from the A direction inside the indoor unit 1 is cooled by the heat exchanger 5, dehumidified, and blown out in the B direction. The cold air blown out reaches every corner of the room by the swinging upper and lower blades 8. When the air conditioning in this room reaches a set temperature (set by a remote controller or the like), the operation of the outdoor unit 2 is stopped. That is, the compressor 3 that is a device for circulating the fluid installed in the outdoor unit 2 stops. In these thermo-off states, the operation of changing the rotational speed of the fan 13 is performed according to the operation time of the compressor.

図1は、本発明の第1の実施の形態における圧縮機とファン回転数の相関図を示すものである。図1において、室外ユニット2に設置された圧縮機の運転時間により室内ユニット1におけるファン7の回転数を小さくする場合の制御を示す。運転時間C以下においてファン7は設定回転数であるが、運転時間D以上では回転数F、運転時間E以上では回転数Gに変化(低下)させることにより熱交換器5からの水滴(水分)を含まれた空気の放出量を低減させる。   FIG. 1 shows a correlation diagram between the compressor and the fan rotation speed in the first embodiment of the present invention. In FIG. 1, the control in the case where the rotation speed of the fan 7 in the indoor unit 1 is reduced by the operation time of the compressor installed in the outdoor unit 2 is shown. The fan 7 has a set rotational speed at an operating time C or less, but changes (decreases) to the rotational speed F at an operating time D or more, and changes (decreases) to the rotational speed G at an operating time E or more. Reduce the amount of air released.

図2は、本発明の第1の実施の形態における圧縮機の運転と時間の相関図を示すものである。横軸に時間、縦軸にサーモオン(圧縮機3運転)とサーモオフ(圧縮機3停止)を示している。図2において、サーモオン時間あるいはサーモオフ時間は部屋の温度により様々に変化する。つまり圧縮機3の運転時間が短い場合は熱交換器5に付着する水分が少なく、運転時間が長い場合は熱交換器5に付着する水分が多いため、ファン7の運転時間
においても圧縮機3の運転時間が短い場合にファン7は低い回転数で運転し、圧縮機3の運転時間が長い場合にファン7は高い回転数で運転する。これにより、熱交換器5の状態(水分(水滴)を含んだ状態)にあった最適な制御を行うことが出来る。
FIG. 2 is a correlation diagram between the operation of the compressor and time in the first embodiment of the present invention. The horizontal axis indicates time, and the vertical axis indicates thermo-on (compressor 3 operation) and thermo-off (compressor 3 stop). In FIG. 2, the thermo-on time or the thermo-off time varies depending on the room temperature. That is, when the operation time of the compressor 3 is short, the amount of moisture adhering to the heat exchanger 5 is small, and when the operation time is long, the amount of water adhering to the heat exchanger 5 is large. When the operating time is short, the fan 7 operates at a low rotational speed, and when the operating time of the compressor 3 is long, the fan 7 operates at a high rotational speed. Thereby, optimal control suitable for the state of the heat exchanger 5 (a state including moisture (water droplets)) can be performed.

以上のように、本発明にかかる空気調和装置は、ファンの制御によって、サーモオフ時の部屋の湿度上昇を防ぐことが可能となるので、除湿機等の用途にも適用できる。   As described above, the air-conditioning apparatus according to the present invention can be applied to applications such as a dehumidifier because it is possible to prevent an increase in the humidity of the room when the thermo is off by controlling the fan.
