Description

中継装置および給湯システムRelay device and hot water supply system
　この発明は、複数の検出装置が検出した検出結果を中継する中継装置および給湯システムに関するものである。 The present invention relates to a relay device and a hot water supply system for relaying detection results detected by a plurality of detection devices.
　従来の空冷ヒートポンプチラーでは、出口水温センサおよび入口水温センサの検出結果を用いた制御を行っている（特許文献１参照）。 In the conventional air-cooled heat pump chiller, control using the detection results of the outlet water temperature sensor and the inlet water temperature sensor is performed (see Patent Document 1).

　近年、給湯システムに組み込まれる負荷機器が多様化しており、例えば、複数の負荷機器のそれぞれに、異なる温度の流体を供給するという需要がある。また、正確な温度の流体を、負荷機器に供給するという需要もある。上記のような需要に対応するためには、給湯システムの状態を検出する検出装置を増やして、給湯システムの制御に用いる情報量を増やす必要性がある。しかしながら、単純に、給湯システムの制御に用いる情報量を増やすと、給湯ユニットが処理する情報量が増大するため、給湯ユニットの処理負荷が増大してしまう。 In recent years, load devices incorporated in a hot water supply system have been diversified. For example, there is a demand for supplying fluids having different temperatures to each of a plurality of load devices. There is also a demand for supplying fluid with accurate temperature to load equipment.

The tank 4 of the example of this embodiment includes a first tank 4A, a second tank 4B, and a third tank 4C. The number of tanks is not limited to three, but may be one or two, or four or more. For example, the first tank 4A, the second tank 4B, and the third tank 4C are configured to store fluids having different temperatures. For example, the first tank 4A is configured to store a fluid having a first temperature that is higher than the temperatures of the fluid stored in the second tank 4B and the third tank 4C. The second tank 4B has a second temperature that is lower than the temperature of the fluid stored in the first tank 4A and higher than the temperature of the fluid stored in the third tank 4C. The fluid is stored. The third tank 4C is configured to store a fluid having a third temperature that is lower than the temperature of the fluid stored in the first tank 4A and the second tank 4B.

The fluid stored in each of the first tank 4A, the second tank 4B, and the third tank 4C is adjusted by adjusting the amount of the fluid that flows into each of the first tank 4A, the second tank 4B, and the third tank 4C.

The first tank 4A in which the high temperature fluid is stored is disposed on the innermost side, and the third tank 4C in which the low temperature fluid is stored is disposed on the outermost side, and the medium temperature fluid is stored. The second tank 4B is disposed between the first tank 4A and the third tank 4C. The first tank 4A in which the high-temperature fluid is stored is disposed on the innermost side, so that the high-temperature fluid is suppressed from being cooled by the outside air. Furthermore, since the second tank 4B for storing the medium temperature fluid is disposed between the first tank 4A for storing the high temperature fluid and the third tank 4C for storing the low temperature fluid, The heat retention of one tank 4A is improved. As described above, by arranging the tank for storing the low-temperature fluid so as to surround the tank for storing the high-temperature fluid, the tank 4 having a high heat retention effect can be configured with a simple configuration. In addition, the tank 4 of this embodiment is not limited to the shape shown in FIG. That is, a tank for storing a low-temperature fluid may be provided so as to surround a tank for storing a high-temperature fluid among a plurality of tanks. Since the tank storing the low-temperature fluid stores at least a fluid having a temperature higher than that of the outside air, the above-described configuration improves the heat retaining effect of the tank.

　実施の形態２．
　図５は、この発明の実施の形態２に係る給湯システムのタンクの構成の一例を模式的に記載した図である。図５に示すように、この実施の形態のタンク４－１は、第１タンク４Ａ－１と第２タンク４Ｂ－１と第３タンク４Ｃ－１とが、上下方向に積層されている。以下の説明では、この実施の形態の理解を容易にするために、上記の実施の形態１と重複する説明については簡略化しまたは省略する。 Embodiment 2. FIG.
FIG. 5 is a diagram schematically illustrating an example of the configuration of the tank of the hot water supply system according to Embodiment 2 of the present invention. As shown in FIG. 5, in the tank 4-1, the first tank 4A-1, the second tank 4B-1, and the third tank 4C-1 are stacked in the vertical direction. In the following description, in order to facilitate understanding of this embodiment, the description overlapping with that of the first embodiment is simplified or omitted.
　高温の流体が貯留される第１タンク４Ａ－１は、最も上方に配設されており、低温の流体が貯留される第３タンク４Ｃ－１は、最も下方に配設されており、中温の流体が貯留される第２タンク４Ｂ－１は、第１タンク４Ａ－１と第３タンク４Ｃ－１との間に配設されている。また、第１タンク４Ａ－１の下部は、第２タンク４Ｂ－１の上部と連通しており、第２タンク４Ｂ－１の下部は、第３タンク４Ｃ－１の上部と連通している。 The first tank 4A-1 in which the high-temperature fluid is stored is disposed at the uppermost position, and the third tank 4C-1 in which the low-temperature fluid is stored is disposed at the lowermost position. The second tank 4B-1 in which the fluid is stored is disposed between the first tank 4A-1 and the third tank 4C-1. The lower part of the first tank 4A-1 communicates with the upper part of the second tank 4B-1, and the lower part of the second tank 4B-1 communicates with the upper part of the third tank 4C-1.
　上記のように、この実施の形態では、タンク４が積層されているため、複数のタンク４のそれぞれが外気に触れる面積が低減されており、タンク４のそれぞれが貯留している流体が外気で冷やされることが抑制されている。 As described above, in this embodiment, since the tanks 4 are stacked, the area where each of the plurality of tanks 4 is exposed to the outside air is reduced, and the fluid stored in each of the tanks 4 is the outside air. Cooling is suppressed.
　また、高温の流体が貯留されるタンク４が低温の流体が貯留されるタンク４よりも上方に配設されているため、タンク４に貯留されている流体の保温が効率良く行われている。 Further, since the tank 4 in which the high temperature fluid is stored is disposed above the tank 4 in which the low temperature fluid is stored, the temperature of the fluid stored in the tank 4 is efficiently maintained.
　また、高温の流体が貯留されるタンク４の下部が、低温の流体が貯留されるタンク４の上部と連通しているため、例えば、第１タンク４Ａ－１で温度が低下した流体が、第１タンク４Ａ－１の下部から、第２タンク４Ｂ－１の上部に流入する。このように、この実施の形態では、高温の流体を貯留するタンク４の内部で冷めた流体が、低温の流体を貯留するタンク４の内部に移動するため、タンク４に貯留された流体の熱が効率良く利用されている。 Further, since the lower part of the tank 4 in which the high-temperature fluid is stored communicates with the upper part of the tank 4 in which the low-temperature fluid is stored, for example, the fluid whose temperature has decreased in the first tank 4A-1 It flows into the upper part of the second tank 4B-1 from the lower part of the first tank 4A-1. Thus, in this embodiment, since the fluid cooled in the tank 4 storing the high-temperature fluid moves to the inside of the tank 4 storing the low-temperature fluid, the heat of the fluid stored in the tank 4 Are used efficiently.

Further, the configuration requirements that are not particularly limited with respect to the arrangement are not limited to the arrangement disclosed in the embodiment, and can be arranged at a position where the function can be achieved.
　例えば、中継装置１は、給湯システム５０の経年変化または運転時間等を監視する機能を含んでいてもよい。例えば、中継装置１は、ユーザの指示を受けて、経年変化または運転時間等の情報を、図３に記載の表示部１０８に表示させることができる。また、中継装置１が、例えばメンテナンス用ＰＣ（図示を省略）と通信するＰＣ通信部（図示を省略）を含んでいる場合には、ユーザは、メンテナンス用ＰＣを中継装置１に接続することによって、メンテナンス項目およびメンテナンス時期を知得することができる。 For example, the relay device 1 may include a function of monitoring the secular change or operation time of the hot water supply system 50. For example, the relay device 1 can display information such as secular change or operation time on the display unit 108 illustrated in FIG. 3 in response to a user instruction. When the relay device 1 includes a PC communication unit (not shown) that communicates with, for example, a maintenance PC (not shown), the user connects the maintenance PC to the relay device 1. Maintenance items and maintenance time can be obtained.
