And comprising.
第一熱交換器１２は、例えばフィンチューブ式熱交換器であり、少ない設置スペースで効率よく外気に伝熱可能である。これにより、第一熱交換器１２を含む室外機３の設置スペースの増大が抑えられるとともに、既設の室外機３に第一熱交換器１２を追加設置する場合にもこれが容易になる。なお、第一熱交換器１２はフィンチューブ式に限らず、気液接触式等の種々の熱交換器を採用可能である。 The first heat exchanger 12 is, for example, a fin tube heat exchanger, and can efficiently transfer heat to the outside air with a small installation space. Thereby, an increase in the installation space of the outdoor unit 3 including the first heat exchanger 12 is suppressed, and this is also facilitated when the first heat exchanger 12 is additionally installed in the existing outdoor unit 3. The first heat exchanger 12 is not limited to the fin tube type, and various heat exchangers such as a gas-liquid contact type can be employed.
第二熱交換器１３は、例えばプレート式熱交換器であり、コンパクトで伝熱性能が高く、メンテナンス性にも優れる。これにより、気体温度調整装置１１の設置がより容易になるとともに、地下水の循環に伴うメンテナンスも容易になる。なお、第二熱交換器１３はプレート式に限らず、スパイラル式等の種々の熱交換器を採用可能である。 The second heat exchanger 13 is, for example, a plate heat exchanger, is compact, has high heat transfer performance, and is excellent in maintainability. Thereby, the installation of the gas temperature adjusting device 11 becomes easier and the maintenance accompanying the circulation of the groundwater becomes easier. The second heat exchanger 13 is not limited to the plate type, and various heat exchangers such as a spiral type can be adopted.
第二熱交換器１３に接続される地下水導入路１４には、スケール防止用の触媒フィルターユニット１４ａが設けられる。なお、地下水を汲み上げるポンプの図示は略すが、このポンプが地下水導入路１４の触媒フィルターユニット１４ａより下流側（第二熱交換器１３側）や地下水排出路１５にあれば、ポンプにおいても触媒フィルターユニット１４ａによるスケール防止効果を得られる。また、地下水排出路１５は、第二熱交換器１３で吸熱又は放熱した地下水を単に下水道等に排出してもよいが、不図示の廃熱利用装置に供給する構成としてもよい。 The groundwater introduction path 14 connected to the second heat exchanger 13 is provided with a catalyst filter unit 14a for preventing scale. Although a pump for pumping up groundwater is not shown, if this pump is located downstream of the catalyst filter unit 14a of the groundwater introduction passage 14 (on the second heat exchanger 13 side) or the groundwater discharge passage 15, the catalyst filter is also used in the pump. The scale prevention effect by the unit 14a can be obtained. The groundwater discharge path 15 may simply discharge the groundwater absorbed or radiated by the second heat exchanger 13 to a sewer or the like, or may be configured to supply to a waste heat utilization device (not shown).
熱媒循環装置１８は、ポンプ等の駆動源を有して中間熱媒体を圧送し、第一熱交換器１２及び第二熱交換器１３の間で中間熱媒体を循環させる。熱媒循環装置１８には、中間熱媒体の散布による揮発等によって不足した中間熱媒体を補給可能とする補給路２１を接続する熱媒補給部１８ａと、熱媒回収装置２０の熱媒回収路２０ｂを接続する熱媒回収部１８ｂと、が設けられる。 The heat medium circulating device 18 has a drive source such as a pump, and pumps the intermediate heat medium, and circulates the intermediate heat medium between the first heat exchanger 12 and the second heat exchanger 13.

熱媒散布装置１９は、第一熱媒流路１６から分岐して延びる散布ノズル１９ａを有する。散布ノズル１９ａは、熱媒循環装置１８から圧送された中間熱媒体を室外機３の外気導入口３ａに向けて滴状又は霧状に散布する。これにより、外気導入口３ａ内の熱交換部３ｃを直接冷却又は加温することが可能である。 The heat medium spraying device 19 has a spray nozzle 19 a that branches off from the first heat medium flow path 16. The spray nozzle 19a sprays the intermediate heat medium pumped from the heat medium circulating device 18 toward the outside air inlet 3a of the outdoor unit 3 in the form of drops or mist. Thereby, it is possible to directly cool or heat the heat exchange part 3c in the outside air inlet 3a.
熱媒回収装置２０には、熱交換器の下方に設けられて熱交換器の下方に流下した中間熱媒体を受け止める回収トレー２０ａと、回収トレー２０ａと熱媒循環装置１８の熱媒回収部１８ｂとを接続する熱媒回収路２０ｂと、が設けられる。回収トレー２０ａが受け止めた中間熱媒体は、不図示のフィルター等を経た後に熱媒循環装置１８内で第一熱媒流路１６に合流し、第一熱交換器１２への供給及び室外機３への散布に再利用される。 The heat medium recovery device 20 includes a recovery tray 20a that is provided below the heat exchanger and receives an intermediate heat medium that has flowed down the heat exchanger, a recovery tray 20a, and a heat medium recovery unit 18b of the heat medium circulation device 18. And a heat medium recovery path 20b for connecting the two. The intermediate heat medium received by the recovery tray 20a passes through a filter (not shown), and then joins the first heat medium flow path 16 in the heat medium circulation device 18 to supply to the first heat exchanger 12 and the outdoor unit 3 Reused for spraying.
中間熱媒体には脱塩水（純水、イオン交換水）が用いられており、中間熱媒体の循環経路や散布装置及び散布相手にスケールが生じることを抑止するとともに、代替フロン等を用いる場合と比べて環境に影響を与えない。中間熱媒体としては、雨水程度に浄化された水であればよく、人為的に生成した脱塩水の他、貯留した雨水をろ過して用いたり補給することも可能である。中間熱媒体は、補給路２１を介して熱媒循環装置１８内の循環経路に補給可能である。また、熱媒回収装置２０を用いることで、中間熱媒体としての純水等を生成するためのコストが抑えられる。 Demineralized water (pure water, ion-exchanged water) is used for the intermediate heat medium, which suppresses the generation of scale in the circulation path of the intermediate heat medium, the spray device, and the spray partner, and when using alternative chlorofluorocarbons, etc. Compared with the environment is not affected. The intermediate heat medium may be water purified to the extent of rainwater, and in addition to artificially generated desalted water, stored rainwater can be filtered and used. The intermediate heat medium can be supplied to the circulation path in the heat medium circulation device 18 via the supply path 21. Moreover, the cost for producing | generating the pure water etc. as an intermediate | middle heat medium by using the heat medium collection | recovery apparatus 20 is suppressed.
次に、室外機システム１０の作用について説明する。 Next, the operation of the outdoor unit system 10 will be described.
一般に、空調装置１が冷房運転の場合に、室外機３において熱交換する外気の温度が高いと、冷暖房平均エネルギー消費効率が低くなる。一方、空調装置１が暖房運転の場合に、室外機３において熱交換する外気の温度が低いと、冷暖房平均エネルギー消費効率が低くなる。 In general, when the air conditioner 1 is in the cooling operation, if the temperature of the outside air that exchanges heat in the outdoor unit 3 is high, the average energy consumption efficiency of the air conditioning becomes low. On the other hand, when the air conditioner 1 is in the heating operation, if the temperature of the outside air that exchanges heat in the outdoor unit 3 is low, the air conditioning average energy consumption efficiency is low.
これに対し、室外機システム１０では、室外機３に導入して熱媒体と熱交換する外気を、室外機３への導入直前に気体温度調整装置１１によって適宜冷却又は加温するので、室外機３で熱交換に供される外気は、その温度が外気温そのままではなく、地熱利用により温度が制御された気体として室外機３に導入されることとなる。 On the other hand, in the outdoor unit system 10, the outdoor air introduced into the outdoor unit 3 and exchanging heat with the heat medium is appropriately cooled or heated by the gas temperature adjusting device 11 immediately before being introduced into the outdoor unit 3. The outside air used for heat exchange in 3 is not introduced into the outdoor unit 3 as a gas whose temperature is controlled by using geothermal heat, instead of the outside air temperature.
第一熱交換器１２を通過して室外機３に導入される外気は、熱交換部３ｃで中間熱媒体との熱交換がなされる。中間熱媒体は、第二熱交換器１３においてほぼ地下水温となるように温度を制御される。例えば中間熱媒体の温度が地下水温と同等の１５度であり、外気温が１５度よりも高い温度であるときには、第一熱交換器１２を通過した外気は、地下水と同等の温度まで冷却される。逆に、外気温が１５度よりも低い温度であるときには、外気温が１５度よりも高い温度まで加温される。 The outdoor air that passes through the first heat exchanger 12 and is introduced into the outdoor unit 3 undergoes heat exchange with the intermediate heat medium in the heat exchange unit 3c. The temperature of the intermediate heat medium is controlled in the second heat exchanger 13 so as to be approximately the groundwater temperature. For example, when the temperature of the intermediate heat medium is 15 degrees equivalent to the groundwater temperature and the outside air temperature is higher than 15 degrees, the outside air that has passed through the first heat exchanger 12 is cooled to a temperature equivalent to the groundwater. The Conversely, when the outside air temperature is a temperature lower than 15 degrees, the outside air temperature is heated to a temperature higher than 15 degrees.
さらに、室外機システム１０では、熱媒散布装置１９により中間熱媒体を室外機３の外気導入口３ａに散布することで、外気温が１５度よりも高い温度であるときには、中間熱媒体の冷熱によって外気導入口３ａ内の熱交換部３ｃが直接冷却されるとともに、中間熱媒体の一部の気化熱によっても前記熱交換部３ｃが冷却される。一方、外気温が１５度よりも低い温度であるときには、中間熱媒体の気化熱として５度程度を差し引いても、中間熱媒体の温熱により外気導入口３ａ内の熱交換部３ｃが直接加温される。 Further, in the outdoor unit system 10, when the outside air temperature is higher than 15 degrees by spraying the intermediate heat medium onto the outside air inlet 3 a of the outdoor unit 3 by the heat medium spraying device 19, As a result, the heat exchanging part 3c in the outside air inlet 3a is directly cooled, and the heat exchanging part 3c is also cooled by the vaporization heat of a part of the intermediate heat medium. On the other hand, when the outside air temperature is lower than 15 degrees, even if about 5 degrees is subtracted as the heat of vaporization of the intermediate heat medium, the heat exchanger 3c in the outside air inlet 3a is directly heated by the heat of the intermediate heat medium. Is done.
このように、室外機３に温度を調整した外気を取り込むとともに、室外機３の熱交換部３ｃを中間熱媒体により直接冷却又は加温することで、空調装置１の冷暖房平均エネルギー消費効率を高め、高い省エネルギー効果を得ることができる。 In this way, the outside air whose temperature is adjusted is taken into the outdoor unit 3 and the heat exchange unit 3c of the outdoor unit 3 is directly cooled or heated by the intermediate heat medium, thereby improving the average energy consumption efficiency of the air conditioner 1. High energy saving effect can be obtained.
また、室外機３からの廃熱が過度に高温化又は低温化することを避け、夏場のヒートアイランド対策や冬場のデフロスト運転の回避を図ることができる。 Further, it is possible to avoid the waste heat from the outdoor unit 3 from becoming excessively high or low, and to prevent heat island measures in summer and defrost operation in winter.
さらに、中間熱媒体と地下水との間で熱交換を行うことで、通年１５度ほどに安定した地下水を利用して中間熱媒体を効率よく冷却又は加温することができる。 Furthermore, by performing heat exchange between the intermediate heat medium and the groundwater, the intermediate heat medium can be efficiently cooled or heated using groundwater that is stable at about 15 degrees throughout the year.
しかも、中間熱媒体に純水を用いることで、中間熱媒体の循環経路や散布装置及び散布相手にスケールが生じることを抑止するとともに、環境に対してローインパクトとすることができる。中間熱媒体の補給は比較的容易であるが、散布した中間熱媒体を回収する熱媒回収装置２０をさらに備えることで、中間熱媒体の補給コストを抑えることができる。 In addition, by using pure water as the intermediate heat medium, it is possible to suppress the occurrence of scale in the circulation path of the intermediate heat medium, the spray device, and the spray partner, and to make the environment low impact. Replenishment of the intermediate heat medium is relatively easy, but by further including the heat medium recovery device 20 that recovers the dispersed intermediate heat medium, the replenishment cost of the intermediate heat medium can be suppressed.
