Description

本発明は、温調対象流体を冷却用熱交換器にて冷却し、冷却された温調対象流体を加熱用熱交換器にて加熱して空調対象空間に供給する温度調整装置に用いられる熱交換器、及びこの熱交換器を備えた温度調整装置に関する。   The present invention cools a temperature adjustment target fluid with a cooling heat exchanger, heats the cooled temperature adjustment target fluid with a heating heat exchanger, and supplies heat to the air conditioning target space. The present invention relates to an exchanger and a temperature adjusting device including the heat exchanger.

従来の温度調整装置は、例えば、圧縮機、凝縮器、膨張部、蒸発器の順に冷媒を循環させる冷凍サイクルを備え、蒸発器を冷却用熱交換器として用いている。そして、蒸発器にて冷媒と温調対象流体とを熱交換させて温調対象流体を冷却し、その冷却された温調対象流体を加熱用熱交換器にて加熱することにより、温調対象流体の温度を目標温度範囲（例えば、目標温度（２０℃）±０．１℃の範囲）内に調整している。そして、温調対象流体は、例えば、空調対象空間に供給する温調対象空気としており、このように温調された目標温度範囲の温調対象空気を空調対象空間に供給するようにしている（例えば、特許文献１参照。）。   A conventional temperature control device includes, for example, a refrigeration cycle that circulates a refrigerant in the order of a compressor, a condenser, an expansion unit, and an evaporator, and uses the evaporator as a heat exchanger for cooling. Then, heat is exchanged between the refrigerant and the temperature adjustment target fluid in the evaporator to cool the temperature adjustment target fluid, and the cooled temperature adjustment target fluid is heated in the heat exchanger for heating, so that the temperature adjustment target is obtained. The temperature of the fluid is adjusted within a target temperature range (for example, a range of target temperature (20 ° C.) ± 0.1 ° C.). The temperature adjustment target fluid is, for example, temperature adjustment target air supplied to the air conditioning target space, and the temperature adjustment target air in the target temperature range thus adjusted in temperature is supplied to the air conditioning target space ( For example, see Patent Document 1.)

例えば、工場等では温度調整装置にて温調対象流体を温調することに加えて、圧縮空気等の温調対象流体とは別の流体を温調したり、各種機器を冷却する等、別の用途でも熱を利用することが求められている場合がある。
そこで、例えば、温度調整装置とは別に熱を発生させる熱源装置を設け、その熱源装置にて発生した熱を別の用途に利用することが考えられる。しかしながら、この場合には、あらたに熱源装置を設けなければならず、設置スペースや配管等の部品点数が増大し構成が大型化するとともに、コストアップを招くことになる。 For example, in a factory, etc., in addition to controlling the temperature of the temperature adjustment target fluid with a temperature adjustment device, the temperature of the fluid other than the temperature adjustment target fluid such as compressed air is adjusted, and various devices are cooled. In some applications, it may be required to use heat.
Therefore, for example, it is conceivable to provide a heat source device that generates heat separately from the temperature adjustment device, and use the heat generated by the heat source device for another purpose. However, in this case, a new heat source device must be provided, which increases the number of components such as installation space and piping, increases the size of the configuration, and increases the cost.

本発明は、かかる点に着目してなされたものであり、その目的は、温調対象流体を温調することに加えて、温度調整装置が発生する熱を別の用途でも利用可能としながら、構成の小型化を実現することが可能な温度調整装置及びこれに用いられる熱交換器を提供する点にある。   The present invention has been made paying attention to such a point, and its purpose is to adjust the temperature of the temperature adjustment target fluid, while making it possible to use the heat generated by the temperature adjustment device in another application, The object of the present invention is to provide a temperature adjusting device capable of realizing a downsizing of the configuration and a heat exchanger used therefor.

上記目的を達成するための本発明に係る熱交換器は、温調対象流体を冷却用熱交換器にて冷却し、冷却された前記温調対象流体を加熱用熱交換器にて加熱して空調対象空間に供給する温度調整装置に用いられる熱交換器であって、その特徴構成は、
前記冷却用熱交換器にて冷却された前記温調対象流体の一部と第１加熱用流体とを熱交換させ当該温調対象流体の一部を加熱する温調流体用加熱部と、前記冷却された温調対象流体の他部と第２加熱用流体とを熱交換させ当該温調対象流体の他部を加熱する加熱部と、前記加熱部の下流側において、前記加熱部にて加熱された前記温調対象流体の他部と前記温調対象流体とは別の別温調対象流体とを熱交換させ当該別温調対象流体を温調する温調部と、を一体化して備えた前記加熱用熱交換器としての熱交換器である点にある。 In order to achieve the above object, a heat exchanger according to the present invention cools a temperature adjustment target fluid with a cooling heat exchanger, and heats the cooled temperature adjustment target fluid with a heating heat exchanger. It is a heat exchanger used in a temperature adjustment device that supplies air-conditioned space, and its characteristic configuration is
A temperature-controlling fluid heating unit that heat-exchanges a part of the temperature-control target fluid cooled by the cooling heat exchanger and the first heating fluid and heats the part of the temperature-control target fluid; Heating the other part of the cooled temperature adjustment target fluid with the second heating fluid to heat the other part of the temperature adjustment target fluid, and heating at the heating part on the downstream side of the heating part And a temperature control unit that performs heat exchange between the other temperature control target fluid and the temperature control target fluid different from the temperature control target fluid to adjust the temperature of the temperature control target fluid. Further, the heat exchanger is a heat exchanger as the heating heat exchanger.

本特徴構成によれば、加熱用熱交換器としての熱交換器が、冷却用熱交換器にて冷却された温調対象流体の一部を加熱する温調流体用加熱部と、冷却された温調対象流体の他部を加熱する加熱部と、温調対象流体とは別の別温調対象流体を温調する温調部とを一体として備えているので、この熱交換器により、温調対象流体の一部を加熱して精密に温調することに加えて、温調対象流体の他部の熱を利用して別温調対象流体を温調することができる。これにより、温調対象流体の熱を用いて温調対象流体とは別の流体を温調したり、各種機器を冷却等することができ、温調対象流体を温調することに加えて、温度調整装置が発生する熱を別の用途でも利用可能となる。
しかも、単に、温度調整装置が発生する熱を別の用途でも利用可能とするだけでなく、温調対象流体の一部を第１加熱用流体との熱交換により温調する熱交換器と、温調対象流体の他部を第２加熱用流体との熱交換により加熱する熱交換器と、別温調対象流体を加熱された温調対象流体の他部との熱交換により温調する熱交換器とを、一つの熱交換器にて兼用してこれら熱交換器の構成の小型化を実現することができる。
また、加熱部の下流側（温調対象流体の流れ方向の下流側）に設けられた温調部において、加熱部により加熱された温調対象流体の他部との熱交換により別温調対象流体を温調する。これにより、別温調対象流体を温調対象流体の他部により温調する前に、予め当該温調対象流体の他部を、別温調対象流体を温調するのに適した温度に加熱部にて加熱しておくことにより、別温調対象流体が目標温度となるように温調することができる。
さらに、温調部を通過した温調対象流体の他部を、空調対象空間外に排気させるのではなく、温調流体用加熱部を通過した温調対象流体の一部に混合させて空調対象空間に供給できるので、温調対象流体の他部を空調対象空間外に排気するための排気路等を別途設けなくてもよく、加熱用熱交換器に供給した温調対象流体の全てを空調対象空間へ供給することができ、温度調整装置の構成の小型化を図ることができる。
よって、温調対象流体を精密に温調することに加えて、温度調整装置が発生する熱を別の用途でも利用可能としながら、構成の小型化を実現することが可能な熱交換器を実現することができる。 According to this characteristic configuration, the heat exchanger as the heating heat exchanger is cooled with the heating unit for the temperature adjustment fluid that heats a part of the temperature adjustment target fluid cooled by the cooling heat exchanger. Since the heating unit that heats the other part of the temperature control target fluid and the temperature control unit that controls the temperature of another temperature control target fluid that is different from the temperature control target fluid are integrally provided, this heat exchanger In addition to heating a part of the temperature adjustment target fluid and precisely adjusting the temperature, the heat of the other temperature adjustment target fluid can be adjusted using the heat of the other part of the temperature adjustment target fluid. Thereby, it is possible to control the temperature of a fluid other than the temperature control target fluid using the heat of the temperature control target fluid, cool various devices, etc., in addition to controlling the temperature of the temperature control target fluid, The heat generated by the temperature adjusting device can be used for other purposes.
Moreover, the heat exchanger that not only makes it possible to use the heat generated by the temperature adjustment device in another application but also controls the temperature of a part of the temperature adjustment target fluid by heat exchange with the first heating fluid; Heat that adjusts the temperature by heat exchange between the heat exchanger that heats the other part of the temperature adjustment target fluid by heat exchange with the second heating fluid and the other part of the temperature adjustment target fluid that has been heated. The heat exchanger can be used in a single heat exchanger, so that the size of the heat exchanger can be reduced.
In addition, in the temperature control unit provided on the downstream side of the heating unit (downstream in the flow direction of the temperature control target fluid), another temperature control target is obtained by heat exchange with the other part of the temperature control target fluid heated by the heating unit. Adjust the temperature of the fluid. As a result, before the temperature of another temperature control target fluid is controlled by the other part of the temperature control target fluid, the other part of the temperature control target fluid is heated to a temperature suitable for temperature control of the temperature control target fluid in advance. By heating in the section, the temperature can be adjusted so that the separate temperature adjustment target fluid becomes the target temperature.
In addition, the other part of the temperature control target fluid that has passed through the temperature control unit is not exhausted outside the air conditioning target space, but is mixed with a part of the temperature control target fluid that has passed through the temperature control fluid heating unit. Since it can be supplied to the space, there is no need to provide a separate exhaust passage for exhausting the other part of the temperature control target fluid out of the air conditioning target space, and the entire temperature control target fluid supplied to the heating heat exchanger is air conditioned. The temperature can be supplied to the target space, and the size of the temperature adjustment device can be reduced.
Therefore, in addition to precisely controlling the temperature of the temperature control target fluid, a heat exchanger that can reduce the size of the configuration while enabling the heat generated by the temperature control device to be used in other applications. can do.

本発明に係る熱交換器の更なる特徴構成は、前記温調流体用加熱部が、加熱用熱交換器において前記温調対象流体が通流する部位全体に対して５０％以上の割合で設置されている点にある。   A further characteristic configuration of the heat exchanger according to the present invention is that the heating unit for the temperature control fluid is installed at a ratio of 50% or more with respect to the entire part through which the temperature control target fluid flows in the heating heat exchanger. It is in the point.

本特徴構成によれば、温調流体用加熱部が、加熱用熱交換器において温調対象流体が通流する部位全体に対して５０％以上の割合で設置されているので、加熱用熱交換器を通過する温調対象流体の過半数以上（上記温調対象流体の一部）を温調流体用加熱部にて加熱して、空調対象空間を温調するのに適した温度に精密に温調することができる。一方で、温調部にて別温調対象流体により加熱若しくは冷却される温調対象流体の他部の割合は過半数未満となるので、この温調対象流体の他部を温調流体用加熱部にて温調された温調対象流体の一部に混合させても、空調対象空間に供給される温調対象流体全体の精密な温調を阻害することはない。すなわち、例えば、温調対象流体の一部が温調流体用加熱部から受ける熱量Ｘは３０００〜４０００（Ｗ）程度であり、温調対象流体の他部が温調部から受ける熱量Ｙは１００〜２００（Ｗ）程度であり、熱量Ｘに対する熱量Ｙの比は、Ｙ／Ｘ＝１／３０〜１／２０程度である。
よって、別温調対象流体を温調させるという別の用途に温度調整装置が発生する熱を利用しながら、精密に温調された温調対象流体を空調対象空間の温調用に利用できる。 According to this characteristic configuration, the heating unit for the temperature control fluid is installed at a rate of 50% or more with respect to the entire part through which the temperature control target fluid flows in the heating heat exchanger. More than half of the temperature control target fluid passing through the chamber (a part of the temperature control target fluid) is heated by the temperature control fluid heating section, and the temperature is precisely adjusted to a temperature suitable for temperature control. Can be adjusted. On the other hand, since the ratio of the other part of the temperature adjustment target fluid heated or cooled by the temperature adjustment target fluid in the temperature adjustment unit is less than a majority, the other part of the temperature adjustment target fluid is used as the temperature adjustment fluid heating unit. Even if it is mixed with a part of the temperature adjustment target fluid that has been temperature-controlled at, precise temperature adjustment of the entire temperature adjustment target fluid supplied to the air-conditioning target space is not hindered. That is, for example, the amount of heat X that a part of the temperature control target fluid receives from the temperature control fluid heating unit is about 3000 to 4000 (W), and the amount of heat Y that the other part of the temperature control target fluid receives from the temperature control unit is 100. The ratio of the heat quantity Y to the heat quantity X is about Y / X = 1/30 to 1/20.
Therefore, while using the heat generated by the temperature adjustment device for another purpose of adjusting the temperature of the separate temperature adjustment target fluid, the temperature adjustment target fluid precisely adjusted in temperature can be used for temperature adjustment of the air conditioning target space.

本発明に係る熱交換器の更なる特徴構成は、前記温調対象流体の通流方向に沿う姿勢で板状のフィンが平行に複数配置され、当該板状のフィンの隣接間に前記温調対象流体が通流可能に構成されるとともに、前記温調流体用加熱部において前記第１加熱用流体が通流する第１伝熱管、前記加熱部において前記第２加熱用流体が通流する第２伝熱管、及び前記温調部において前記別温調対象流体が通流する第３伝熱管のそれぞれを、複数の前記板状のフィンを貫通して当該フィンに対して垂直に配設させて、前記温調流体用加熱部、前記加熱部及び前記温調部のそれぞれを形成し、前記温調流体用加熱部と温調部との並び方向が、前記温調対象流体の通流方向に対して垂直で、かつ前記板状のフィンに対して平行な方向となるように構成されている点にある。   A further characteristic configuration of the heat exchanger according to the present invention is that a plurality of plate-like fins are arranged in parallel in a posture along the flow direction of the temperature adjustment target fluid, and the temperature adjustment is between adjacent plate-like fins. A first heat transfer pipe through which the first heating fluid flows in the heating unit for temperature control fluid and a second heating fluid through which the second heating fluid flows in the heating unit are configured to allow the target fluid to flow. 2 heat transfer pipes and a third heat transfer pipe through which the separate temperature control target fluid flows in the temperature control section are arranged perpendicularly to the fins through the plurality of plate-like fins. The temperature adjusting fluid heating unit, the heating unit, and the temperature adjusting unit are formed, and the arrangement direction of the temperature adjusting fluid heating unit and the temperature adjusting unit is the flow direction of the temperature adjustment target fluid. It is configured to be perpendicular to the plate-shaped fin and parallel to the plate-like fin. There to that point.

本特徴構成によれば、複数配置された板状のフィンの隣接間を温調対象流体が通流し、温調流体用加熱部と温調部との並び方向が、温調対象流体の通流方向に対して垂直で、板状のフィンに対して平行な方向となるように配置されているので、第１伝熱管を通流する第１加熱用流体と熱交換した後の温調対象流体の一部と、第３伝熱管を通流する別温調対象流体と熱交換した後の温調対象流体の他部との混合が阻害されることがなく、空調対象空間に供給する前に加熱用熱交換器において混合させることができる。   According to this characteristic configuration, the temperature adjustment target fluid flows between adjacent plate-shaped fins that are arranged in plural, and the arrangement direction of the temperature adjustment fluid heating unit and the temperature adjustment unit is the flow of the temperature adjustment target fluid. Since it is arranged so as to be perpendicular to the direction and parallel to the plate-like fins, the temperature adjustment target fluid after heat exchange with the first heating fluid flowing through the first heat transfer tube Before being supplied to the air-conditioning target space without interfering with the mixing of a part of the temperature control target fluid flowing through the third heat transfer tube with the other temperature control target fluid after heat exchange. It can be mixed in a heat exchanger for heating.

上記目的を達成するための本発明に係る温度調整装置は、温調対象流体を冷却用熱交換器にて冷却し、冷却された前記温調対象流体を加熱用熱交換器にて加熱して空調対象空間に供給する温度調整装置であって、その特徴構成は、
前記加熱用熱交換器として、上記何れか一つの特徴構成を備えた熱交換器を備え、圧縮機、凝縮器、膨張部、蒸発器の順に冷媒を循環させる冷凍サイクルを備える構成で、前記蒸発器を通流する前記冷媒を熱源として前記温調対象流体を冷却するとともに、前記圧縮機から吐出する前記冷媒を分岐させ、前記分岐された冷媒の一部を前記加熱用熱交換器における前記温調流体用加熱部を通流する前記第１加熱用流体とし、かつ、前記分岐された冷媒の他部を前記加熱用熱交換器における前記加熱部を通流する前記第２加熱用流体としている点にある。 In order to achieve the above object, a temperature control device according to the present invention cools a temperature adjustment target fluid with a cooling heat exchanger, and heats the cooled temperature adjustment target fluid with a heating heat exchanger. It is a temperature adjustment device that supplies air-conditioned space, and its characteristic configuration is
The heating heat exchanger includes a heat exchanger having any one of the above-described features, and includes a refrigeration cycle in which a refrigerant is circulated in the order of a compressor, a condenser, an expansion unit, and an evaporator. Cooling the temperature adjustment target fluid using the refrigerant flowing through a heat source as a heat source, branching off the refrigerant discharged from the compressor, and transferring a part of the branched refrigerant to the temperature in the heat exchanger for heating. The first heating fluid that flows through the heating unit for regulating fluid is used, and the other part of the branched refrigerant is used as the second heating fluid that flows through the heating unit in the heating heat exchanger. In the point.

本特徴構成によれば、温調対象流体を加熱して精密に温調することに加えて、温度調整装置が発生する熱を別の用途でも利用可能となる。しかも、単に、温度調整装置が発生する熱を別の用途でも利用可能とするだけでなく、温調対象流体の一部を第１加熱用流体との熱交換により温調する熱交換器と、温調対象流体の他部を第２加熱用流体との熱交換により加熱する熱交換器と、別温調対象流体を加熱された温調対象流体の他部との熱交換により温調する熱交換器とを、一つの熱交換器にて兼用して温度調整装置の構成の小型化を実現することができる。また、温調流体用加熱部において加熱用熱交換器を通過する温調対象流体の一部を加熱するとともに、加熱部において加熱用熱交換器を通過する温調対象流体の他部を加熱し、この加熱部の下流側（温調対象流体の流れ方向の下流側）に設けられた温調部において、加熱部により加熱された温調対象流体の他部との熱交換により別温調対象流体を温調する。これにより、別温調対象流体を温調対象流体の他部により温調する前に、予め当該温調対象流体の他部を、別温調対象流体を温調するのに適した温度に加熱部にて加熱しておくことにより、別温調対象流体が目標温度となるように温調することができる。さらに、温調部を通過した温調対象流体の他部を、空調対象空間外に排気させるのではなく、温調流体用加熱部を通過した温調対象流体の一部に混合させて空調対象空間に供給できるので、温調対象流体の他部を空調対象空間外に排気するための排気路等を別途設けなくてもよく、加熱用熱交換器に供給した温調対象流体の全てを空調対象空間へ供給することができ、温度調整装置の構成の小型化を図ることができる。加えて、冷凍サイクルを循環する冷媒のみを熱源として、温調対象流体を冷却するとともに、冷却された温調対象流体のうち一部を温調流体用加熱部において加熱し、温調対象流体の他部を加熱部において加熱することができる。なお、この加熱部で加熱された温調対象流体の他部により、別温調対象流体は温調される。これにより、一つの冷凍サイクルを通流する一つの冷媒を熱源として、温調対象流体の温調（冷却・加熱）を行うことができるとともに、別温調対象流体の温調（冷却・加熱）も行うことが可能となり、別途の熱源を設ける必要がなく、温度調整装置の構成の簡略化及び小型化を実現することができる。
よって、温調対象流体を温調することに加えて、温度調整装置が発生する熱を別の用途でも利用可能としながら、構成の小型化を実現することが可能な温度調整装置を実現することができる。 According to this characteristic configuration, in addition to heating the temperature adjustment target fluid and precisely adjusting the temperature, the heat generated by the temperature adjustment device can be used in other applications. Moreover, the heat exchanger that not only makes it possible to use the heat generated by the temperature adjustment device in another application but also controls the temperature of a part of the temperature adjustment target fluid by heat exchange with the first heating fluid; Heat that adjusts the temperature by heat exchange between the heat exchanger that heats the other part of the temperature adjustment target fluid by heat exchange with the second heating fluid and the other part of the temperature adjustment target fluid that has been heated. The heat exchanger can be shared by a single heat exchanger, and the temperature control device can be downsized. In addition, the temperature control fluid heating unit heats a part of the temperature control target fluid that passes through the heating heat exchanger, and the heating unit heats the other part of the temperature control target fluid that passes through the heating heat exchanger. In the temperature control unit provided on the downstream side of this heating unit (downstream in the flow direction of the temperature control target fluid), another temperature control target is obtained by heat exchange with the other part of the temperature control target fluid heated by the heating unit. Adjust the temperature of the fluid. As a result, before the temperature of another temperature control target fluid is controlled by the other part of the temperature control target fluid, the other part of the temperature control target fluid is heated to a temperature suitable for temperature control of the temperature control target fluid in advance. By heating in the section, the temperature can be adjusted so that the separate temperature adjustment target fluid becomes the target temperature. In addition, the other part of the temperature control target fluid that has passed through the temperature control unit is not exhausted outside the air conditioning target space, but is mixed with a part of the temperature control target fluid that has passed through the temperature control fluid heating unit. Since it can be supplied to the space, there is no need to provide a separate exhaust passage for exhausting the other part of the temperature control target fluid out of the air conditioning target space, and the entire temperature control target fluid supplied to the heating heat exchanger is air conditioned. The temperature can be supplied to the target space, and the size of the temperature adjustment device can be reduced. In addition, using only the refrigerant circulating in the refrigeration cycle as a heat source, the temperature adjustment target fluid is cooled, and part of the cooled temperature adjustment target fluid is heated in the heating unit for the temperature adjustment fluid. The other part can be heated in the heating part. Note that the temperature of the separate temperature adjustment target fluid is adjusted by the other part of the temperature adjustment target fluid heated by the heating unit. As a result, the temperature of the temperature adjustment target fluid can be adjusted (cooling / heating) using one refrigerant flowing through one refrigeration cycle as a heat source, and the temperature adjustment (cooling / heating) of another temperature adjustment target fluid can be performed. Therefore, there is no need to provide a separate heat source, and the configuration of the temperature adjustment device can be simplified and downsized.
Therefore, in addition to controlling the temperature of the temperature adjustment target fluid, it is possible to realize a temperature adjustment device capable of realizing a downsizing of the configuration while making it possible to use the heat generated by the temperature adjustment device for other purposes. Can do.

In FIG. 1 and FIG. 2, the refrigerant A flowing through the first branch combined flow path 8 is the refrigerant A1 (an example of the first heating fluid), and the refrigerant A flowing through the second branch combined flow path 9 is the refrigerant A2. It is described as (an example of the second heating fluid).

そして、温度調整装置Ｄには、温調対象流体Ｐを送風させる送風ファン６が備えられている。また、温度調整装置Ｄには、温調対象流体Ｐを、送風ファン６、蒸発器４、加熱用熱交換器Ｂ、空調対象空間Ｋ、送風ファン６の順に循環通流させることが可能な通風路（図示せず）が設けられている。よって、この送風ファン６により、通風路内を上記順に温調対象流体Ｐが通流することが可能に構成されている。なお、この通風路の一部、すなわち、蒸発器４と加熱用熱交換器Ｂとの間には、蒸発器４と加熱用熱交換器Ｂとの間の空間を囲繞するダクト１２が設けられている。このダクト１２により、温調対象流体Ｐの通流を阻害しない状態で、蒸発器４にて冷却された温調対象流体Ｐの全量を加熱用熱交換器Ｂに供給することが可能に構成されている。   The temperature adjusting device D is provided with a blower fan 6 for blowing the temperature adjustment target fluid P. In addition, the temperature adjusting device D can ventilate the temperature adjustment target fluid P in the order of the blower fan 6, the evaporator 4, the heating heat exchanger B, the air-conditioning target space K, and the blower fan 6 in this order. A path (not shown) is provided. Therefore, the blower fan 6 is configured to allow the temperature adjustment target fluid P to flow through the ventilation path in the order described above. A duct 12 surrounding the space between the evaporator 4 and the heating heat exchanger B is provided between a part of this ventilation path, that is, between the evaporator 4 and the heating heat exchanger B. ing. The duct 12 is configured so that the entire amount of the temperature adjustment target fluid P cooled by the evaporator 4 can be supplied to the heating heat exchanger B in a state where the flow of the temperature adjustment target fluid P is not hindered. ing.

圧縮空気回路１３は、別温調対象流体Ｑ（圧縮空気）を、加熱用熱交換器Ｂにおける別温調対象流体冷却用の冷却部Ｂ２ｂ（温調部の一例）を介して循環通流させることが可能に構成されている。   The compressed air circuit 13 circulates the separate temperature adjustment target fluid Q (compressed air) through the cooling unit B2b (an example of the temperature adjustment unit) for cooling the separate temperature adjustment target fluid in the heat exchanger B for heating. It is configured to be possible.

次に、図１及び図２に示すように、本発明に係る加熱用熱交換器Ｂは、温調対象流体Ｐ、冷媒Ａ１、冷媒Ａ２及び別温調対象流体Ｑの４つの流体を熱交換対象とするフィン・チューブ熱交換器である。   Next, as shown in FIGS. 1 and 2, the heat exchanger B for heating according to the present invention performs heat exchange between four fluids, ie, a temperature adjustment target fluid P, a refrigerant A1, a refrigerant A2, and another temperature adjustment target fluid Q. This is a finned tube heat exchanger.

加熱用熱交換器Ｂは、箱形状の筐体１４内に、温調対象流体Ｐの通流方向に沿う姿勢で板状のフィン１５が平行に複数配置され、板状のフィン１５の隣接間に温調対象流体Ｐが通流可能に構成されている。   In the heat exchanger B for heating, a plurality of plate-like fins 15 are arranged in parallel in a posture along the flow direction of the temperature control target fluid P in a box-shaped housing 14, and between the adjacent plate-like fins 15. The temperature control target fluid P is configured to be able to flow therethrough.

加熱用熱交換器Ｂには、温調対象流体Ｐの一部を所望温度に加熱する温調流体用加熱部Ｂ１が設けられている。この温調流体用加熱部Ｂ１は、圧縮機１から吐出され冷媒回路５から分岐合流路７に分岐された冷媒Ａの一部である冷媒Ａ１が通流する第１伝熱管１６が、上記板状のフィン１５に対して垂直な方向となるように配置されて形成されている。そして、温調流体用加熱部Ｂ１は、蒸発器４にて冷却された温調対象流体Ｐの一部と冷媒Ａの一部である冷媒Ａ１とを熱交換させて、温調対象流体Ｐの一部を加熱するように構成されている。   The heating heat exchanger B is provided with a temperature adjusting fluid heating unit B1 for heating a part of the temperature adjusting target fluid P to a desired temperature. The temperature control fluid heating section B1 includes a first heat transfer pipe 16 through which the refrigerant A1 that is a part of the refrigerant A discharged from the compressor 1 and branched from the refrigerant circuit 5 to the branch joint channel 7 flows. The fins 15 are arranged and formed so as to be perpendicular to the fins 15. And the heating part B1 for temperature control fluid heat-exchanges a part of temperature control object fluid P cooled with the evaporator 4, and the refrigerant | coolant A1 which is a part of refrigerant | coolant A of temperature control object fluid P It is configured to heat a portion.

また、加熱用熱交換器Ｂには、温調対象流体Ｐの他部を所望温度に加熱する加熱部Ｂ２ａが設けられている。この加熱部Ｂ２ａは、圧縮機１から吐出され冷媒回路５から分岐合流路７に分岐された冷媒Ａの他部である冷媒Ａ２が通流する第２伝熱管１７が、上記板状のフィン１５に対して垂直な方向となるように配置されて形成されている。そして、加熱部Ｂ２ａは、蒸発器４にて冷却された温調対象流体Ｐの他部と冷媒Ａの他部である冷媒Ａ２とを熱交換させて、温調対象流体Ｐの他部を加熱するように構成されている。
さらに、加熱用熱交換器Ｂには、別温調対象流体Ｑを所望温度に冷却する冷却部Ｂ２ｂが、温調対象流体Ｐの他部を加熱する加熱部Ｂ２ａの下流側（温調対象流体Ｐの通流方向の下流側）に設けられている。この冷却部Ｂ２ｂは、別温調対象流体Ｑが通流する第３伝熱管１８が、上記板状のフィン１５に対して垂直な方向となるように配置されて形成されている。そして、冷却部Ｂ２ｂは、加熱部Ｂ２ａにて加熱された温調対象流体Ｐの他部と別温調対象流体Ｑとを熱交換させて、別温調対象流体Ｑを冷却するように構成されている。したがって、別温調対象流体Ｑを温調対象流体Ｐの他部により冷却する前に、予め温調対象流体Ｐの他部を加熱部Ｂ２ａにて適切に加熱しておくことにより、別温調対象流体Ｑが目標温度となるように冷却することができる。 Further, the heating heat exchanger B is provided with a heating unit B2a that heats the other part of the temperature adjustment target fluid P to a desired temperature. In the heating section B2a, the second heat transfer tube 17 through which the refrigerant A2 which is the other part of the refrigerant A discharged from the compressor 1 and branched from the refrigerant circuit 5 to the branching flow path 7 flows is the plate-like fin 15. Are arranged so as to be perpendicular to each other. And the heating part B2a heat-exchanges the other part of the temperature control object fluid P cooled with the evaporator 4, and the refrigerant | coolant A2 which is the other part of the refrigerant | coolant A, and heats the other part of the temperature control object fluid P. Is configured to do.
Further, in the heat exchanger B for heating, a cooling unit B2b that cools the separate temperature adjustment target fluid Q to a desired temperature is provided downstream of the heating unit B2a that heats the other part of the temperature adjustment target fluid P (temperature adjustment target fluid). It is provided on the downstream side in the flow direction of P). The cooling section B2b is formed by arranging the third heat transfer tube 18 through which the separate temperature adjustment target fluid Q flows in a direction perpendicular to the plate-like fins 15. And cooling part B2b is comprised so that the other part of temperature regulation object fluid P heated by heating part B2a and another temperature regulation object fluid Q may be heat-exchanged, and another temperature regulation object fluid Q may be cooled. ing. Therefore, before the other temperature adjustment target fluid Q is cooled by the other part of the temperature adjustment target fluid P, the other part of the temperature adjustment target fluid P is appropriately heated in advance by the heating unit B2a, thereby different temperature adjustment. It can cool so that the target fluid Q may become target temperature.

そして、各伝熱管１６，１７，１８は、平行に並ぶ全ての板状のフィン１５を貫通したのち折り返す形態で、当該フィン１５の長手方向（図２中、上下方向）に連続して配設されている。
加熱用熱交換器Ｂにおける温調流体用加熱部Ｂ１と加熱部Ｂ２ａ及び冷却部Ｂ２ｂとの配置関係は、温調流体用加熱部Ｂ１と、加熱部Ｂ２ａ及び冷却部Ｂ２ｂとの並び方向が、温調対象流体の通流方向に対して垂直で、板状のフィン１５に対して平行な並び方向となるように配置されている（図２中、上下方向であり、図２では、筐体１４の上部に温調流体用加熱部Ｂ１が、下部に加熱部Ｂ２ａ及び冷却部Ｂ２ｂが配置されている）。なお、上述のとおり、加熱部Ｂ２ａと冷却部Ｂ２ｂとの配置関係は、筐体１４の下部で、温調対象流体Ｐの通流方向の上流側に加熱部Ｂ２ａが配置され、下流側に冷却部Ｂ２ｂが配置されている。したがって、加熱用熱交換器Ｂにおけるフィン１５の隣接間において、温調流体用加熱部Ｂ１における第１伝熱管１６を通流する冷媒Ａ１と熱交換した後の温調対象流体Ｐの一部と、冷却部Ｂ２ｂにおける第３伝熱管１８を通流する別温調対象流体Ｑと熱交換した後の温調対象流体Ｐの他部との混合が阻害されることがなく、空調対象空間Ｋに供給する前に加熱用熱交換器Ｂにおいて温調対象流体Ｐを混合させることができる。 The heat transfer tubes 16, 17, and 18 are continuously arranged in the longitudinal direction (vertical direction in FIG. 2) of the fins 15 in such a manner that they pass through all the plate-like fins 15 arranged in parallel and then turn back. Has been.
In the heat exchanger B for heating, the arrangement relationship between the heating unit B1 for temperature control fluid, the heating unit B2a, and the cooling unit B2b is such that the alignment direction of the heating unit B1 for temperature control fluid, the heating unit B2a, and the cooling unit B2b is Arranged so as to be aligned in a direction perpendicular to the flow direction of the temperature control target fluid and parallel to the plate-like fins 15 (in FIG. 2, it is the vertical direction. In FIG. 14 is provided with a temperature-controlling fluid heating part B1 in the upper part, and a heating part B2a and a cooling part B2b in the lower part. As described above, the arrangement relationship between the heating unit B2a and the cooling unit B2b is such that the heating unit B2a is disposed on the upstream side in the flow direction of the temperature adjustment target fluid P at the lower part of the casing 14, and the cooling is performed on the downstream side. Part B2b is arranged. Therefore, between the adjacent fins 15 in the heat exchanger B for heating, a part of the temperature control target fluid P after heat exchange with the refrigerant A1 flowing through the first heat transfer pipe 16 in the heating unit B1 for temperature control fluid The mixing with the other part of the temperature control target fluid P after heat exchange with the other temperature control target fluid Q flowing through the third heat transfer pipe 18 in the cooling unit B2b is not hindered, and the air conditioning target space K is not disturbed. Before supply, the temperature adjustment target fluid P can be mixed in the heat exchanger B for heating.

また、加熱用熱交換器Ｂにおいて、温調対象流体Ｐが通流する部位全体に対して５０％以上の割合で温調流体用加熱部Ｂ１が設置されている（図２では、温調流体用加熱部Ｂ１が７０％程度の割合で設置されている）ので、加熱用熱交換器Ｂを通過する温調対象流体Ｐの過半数以上（温調対象流体Ｐの一部）を温調流体用加熱部Ｂ１にて加熱して温調することができ、空調対象空間Ｋに供給される温調対象流体Ｐを空調対象空間Ｋを温調するのに適した温度に精密に温調できる。一方で、別温調対象流体Ｑは冷却部Ｂ２ｂにおいて、加熱用熱交換器Ｂを通過する温調対象流体Ｐの他部により冷却されて温調されるが、冷却部Ｂ２ｂにて別温調対象流体Ｑにより加熱される温調対象流体Ｐの他部の割合は温調対象流体Ｐ全体に対して過半数未満となるので、この温調対象流体Ｐの他部を温調流体用加熱部Ｂ１にて温調された温調対象流体Ｐの一部に混合させても、空調対象空間Ｋに供給される温調対象流体Ｐ全体の精密な温調を阻害することはない。すなわち、加熱用熱交換器Ｂ（温調流体用加熱部Ｂ１）を通過した温調対象流体Ｐの一部は、温調対象流体Ｐの他部の合流によりその温度が変化するが、温調対象流体Ｐの他部が冷却部Ｂ２ｂから受ける熱量Ｙは、温調対象流体Ｐの一部が温調流体用加熱部Ｂ１から受ける熱量Ｘに比べて比較的少ないので、温調対象流体Ｐの精密な温調を阻害することはない。例えば、温調対象流体Ｐの一部が温調流体用加熱部Ｂ１から受ける熱量Ｘは３０００〜４０００（Ｗ）程度であり、温調対象流体Ｐの他部が冷却部Ｂ２ｂから受ける熱量は１００〜２００（Ｗ）程度であり、熱量Ｘに対する熱量Ｙの比は、Ｙ／Ｘ＝１／３０〜１／２０程度である。したがって、別温調対象流体Ｑを冷却することにより、温調対象流体Ｐの精密な温調を阻害することはない。これにより、温調対象流体Ｐの他部を温度調整装置Ｄ外に排気させる排気路を設けずに温調対象流体Ｐの全てを空調対象空間Ｋへ供給することができるとともに、別温調対象流体Ｑを冷却しながらも、精密に温調された温調対象流体Ｐにて空調対象空間Ｋを精密に温調するという元々の機能を損なうことがない。   In addition, in the heat exchanger B for heating, the heating unit B1 for temperature adjusting fluid is installed at a ratio of 50% or more with respect to the entire portion through which the temperature adjusting target fluid P flows (in FIG. 2, the temperature adjusting fluid is shown). The heating unit B1 is installed at a ratio of about 70%), so that a majority of the temperature adjustment target fluid P passing through the heating heat exchanger B (a part of the temperature adjustment target fluid P) is used for the temperature adjustment fluid. The temperature can be adjusted by heating in the heating unit B1, and the temperature adjustment target fluid P supplied to the air conditioning target space K can be precisely adjusted to a temperature suitable for adjusting the temperature of the air conditioning target space K. On the other hand, the separate temperature adjustment target fluid Q is cooled and adjusted by the other part of the temperature adjustment target fluid P passing through the heating heat exchanger B in the cooling unit B2b. Since the ratio of the other part of the temperature control target fluid P heated by the target fluid Q is less than a majority with respect to the entire temperature control target fluid P, the other part of the temperature control target fluid P is used as the temperature control fluid heating unit B1. Even if it is mixed with a part of the temperature adjustment target fluid P whose temperature has been adjusted in step (a), precise temperature adjustment of the entire temperature adjustment target fluid P supplied to the air conditioning target space K is not hindered. That is, the temperature of a part of the temperature control target fluid P that has passed through the heat exchanger B for heating (temperature control fluid heating part B1) changes due to the merging of the other part of the temperature control target fluid P. The amount of heat Y received by the other part of the target fluid P from the cooling unit B2b is relatively small compared to the amount of heat X received by the temperature control target fluid P from the heating unit B1 for the temperature control fluid. It does not interfere with precise temperature control. For example, the amount of heat X that a part of the temperature control target fluid P receives from the temperature control fluid heating unit B1 is about 3000 to 4000 (W), and the amount of heat that the other part of the temperature control target fluid P receives from the cooling unit B2b is 100. The ratio of the heat quantity Y to the heat quantity X is about Y / X = 1/30 to 1/20. Therefore, by cooling the separate temperature adjustment target fluid Q, precise temperature adjustment of the temperature adjustment target fluid P is not hindered. Thereby, all the temperature control target fluid P can be supplied to the air conditioning target space K without providing an exhaust passage for exhausting the other part of the temperature control target fluid P to the outside of the temperature adjustment device D, and another temperature control target. While cooling the fluid Q, the original function of precisely controlling the temperature of the air-conditioning target space K with the temperature control target fluid P that has been precisely controlled is not impaired.

よって、加熱用熱交換器Ｂは、上述のとおり、蒸発器４にて冷却された温調対象流体Ｐの一部を加熱する温調流体用加熱部Ｂ１と、冷却された温調対象流体Ｐの他部を加熱する加熱部Ｂ２ａと、温調対象流体Ｐとは別の別温調対象流体Ｑを冷却する冷却部Ｂ２ｂとを一体として備えているので、温調対象流体Ｐの一部を加熱して精密に温調することに加えて、温調対象流体Ｐの他部の冷熱を利用して別温調対象流体Ｑを冷却することができる。これにより、温調対象流体Ｐの冷熱を用いて温調対象流体Ｐとは別の別温調対象流体Ｑを冷却して、その別温調対象流体Ｑを各種精密加工機器を冷却するために用いることができ、温調対象流体Ｐを温調することに加えて、温度調整装置Ｄが発生する熱を別の用途でも利用可能となる。
しかも、単に、温度調整装置Ｄが発生する熱を別の用途でも利用可能とするだけでなく、温調対象流体Ｐの一部を温調する熱交換器と、温調対象流体Ｐの他部を加熱する熱交換器と、別温調対象流体Ｑを冷却する熱交換器とを、一つの熱交換器にて兼用してこれら熱交換器（加熱用熱交換器Ｂ）の構成の小型化を実現することができる。 Therefore, the heat exchanger B for heating is, as described above, the heating unit B1 for temperature control fluid that heats a part of the temperature control target fluid P cooled by the evaporator 4, and the cooled temperature control target fluid P. Since the heating part B2a that heats the other part and the cooling part B2b that cools the separate temperature adjustment target fluid Q different from the temperature adjustment target fluid P are integrally provided, a part of the temperature adjustment target fluid P is provided. In addition to heating and precisely adjusting the temperature, the other temperature adjustment target fluid Q can be cooled by using the cold heat of the other part of the temperature adjustment target fluid P. Accordingly, in order to cool another temperature control target fluid Q different from the temperature control target fluid P using the cooling heat of the temperature control target fluid P, and to cool the various temperature control target fluid Q to various precision processing devices. In addition to controlling the temperature of the temperature adjustment target fluid P, the heat generated by the temperature adjustment device D can be used for other purposes.
Moreover, not only can the heat generated by the temperature control device D be used for other purposes, but also a heat exchanger that controls the temperature of a part of the temperature adjustment target fluid P and the other part of the temperature control target fluid P. Of the heat exchanger (heating heat exchanger B) by combining the heat exchanger that heats the heat exchanger and the heat exchanger that cools the separate temperature control target fluid Q in a single heat exchanger. Can be realized.

なお、温度調整装置Ｄは、空調対象空間Ｋとの間で温調対象流体Ｐを循環して空調対象空間Ｋを温調するように構成されている。例えば、空調対象空間Ｋから温度調整装置Ｄに戻された温調対象流体Ｐの一部を装置外に排気させると、循環させる温調対象流体Ｐの流量を確保するために外気を取り入れる必要がある。この場合には、全く温調されていない外気を取り入れることになり、温調対象流体Ｐを精密に温調し難くなり、空調対象空間Ｋの温調を精密に行い難くなる可能性がある。また、外気には、塵埃等が含まれている場合があり、外気の取り入れにより空調対象空間Ｋのクリーン度が低下する可能性がある。
本発明に係る温度調整装置Ｄでは、空調対象空間Ｋから温度調整装置Ｄに戻された温調対象流体Ｐを蒸発器４にて冷却するとともに、蒸発器４にて冷却された温調対象流体Ｐの全量を加熱用熱交換器Ｂに供給して、主として加熱用熱交換器Ｂにおける温調流体用加熱部Ｂ１にて精密に温調し、空調対象空間Ｋに供給するようにしている。これにより、空調対象空間Ｋから温度調整装置Ｄに戻された温調対象流体Ｐを精密に温調して空調対象空間Ｋに供給することができるので、温調対象流体Ｐの流れとしては、温度調整装置Ｄと空調対象空間Ｋとの間で循環する閉回路とすることができる。よって、外気を取り入れる必要がない又はほとんどなくなり、空調対象空間Ｋの温調を精密に行い難くなる、或いは、空調対象空間Ｋのクリーン度が低下するという問題の発生を防止することができる。 The temperature adjustment device D is configured to circulate the temperature adjustment target fluid P between itself and the air conditioning target space K to adjust the temperature of the air conditioning target space K. For example, when a part of the temperature adjustment target fluid P returned from the air conditioning target space K to the temperature adjustment device D is exhausted outside the device, it is necessary to take in the outside air in order to secure the flow rate of the temperature adjustment target fluid P to be circulated. is there. In this case, outside air that has not been temperature-controlled is taken in, and it becomes difficult to precisely control the temperature of the temperature-control target fluid P, and it may be difficult to accurately control the temperature of the air-conditioning target space K. Moreover, the outside air may contain dust or the like, and the cleanliness of the air-conditioning target space K may be reduced by taking in the outside air.
In the temperature adjustment device D according to the present invention, the temperature adjustment target fluid P returned from the air conditioning target space K to the temperature adjustment device D is cooled by the evaporator 4 and the temperature adjustment target fluid cooled by the evaporator 4. The whole amount of P is supplied to the heat exchanger B for heating, and the temperature is precisely adjusted mainly by the heating unit B1 for the temperature adjusting fluid in the heat exchanger B for heating, and supplied to the air-conditioning target space K. As a result, the temperature adjustment target fluid P returned from the air conditioning target space K to the temperature adjustment device D can be precisely temperature-controlled and supplied to the air conditioning target space K. A closed circuit that circulates between the temperature adjusting device D and the air-conditioning target space K can be provided. Therefore, it is not necessary or almost no need to take in outside air, and it becomes difficult to precisely control the temperature of the air-conditioning target space K, or the occurrence of the problem that the cleanness of the air-conditioning target space K is reduced can be prevented.

温度調整装置Ｄにおいて、温調対象流体Ｐ及び別温調対象流体Ｑを温調させるときの動作について説明する。
まず、蒸発器４において冷媒Ａと温調対象流体Ｐとを熱交換させて、冷媒Ａにて温調対象流体Ｐを所望温度に冷却する。このとき、例えば、蒸発器４を通過した温調対象流体Ｐの温度を検出する図外の温度センサの検出情報に基づいて、蒸発器４を通流させる冷媒Ａの通流量や送風ファン６による温調対象流体Ｐの送風量等を調整することにより、蒸発器４を通過した温調対象流体Ｐの温度を、例えば１７±１℃程度の所望温度にまで冷却させる。なお、例えば、蒸発器４に供給される温調対象流体Ｐの温度は２２℃程度とされる。 The operation when the temperature adjustment device D adjusts the temperature of the temperature adjustment target fluid P and the separate temperature adjustment target fluid Q will be described.
First, the refrigerant A and the temperature adjustment target fluid P are heat-exchanged in the evaporator 4, and the temperature adjustment target fluid P is cooled to a desired temperature by the refrigerant A. At this time, for example, based on detection information of a temperature sensor (not shown) that detects the temperature of the temperature adjustment target fluid P that has passed through the evaporator 4, the flow rate of the refrigerant A flowing through the evaporator 4 and the blower fan 6 The temperature of the temperature adjustment target fluid P that has passed through the evaporator 4 is cooled to a desired temperature of about 17 ± 1 ° C., for example, by adjusting the air flow rate of the temperature adjustment target fluid P. For example, the temperature of the temperature adjustment target fluid P supplied to the evaporator 4 is about 22 ° C.

そして、温調対象流体Ｐは、蒸発器４にて冷却されたのちダクト１２を通流して温調対象流体Ｐの全量が加熱用熱交換器Ｂに導入される。
ダクト１２内の上方を通流して加熱用熱交換器Ｂに導入された温調対象流体Ｐ（温調対象流体Ｐの一部）は、温調流体用加熱部Ｂ１にて冷媒Ａ１により所望温度にまで精密に加熱される。例えば、温調流体用加熱部Ｂ１を通過した温調対象流体Ｐの一部の温度を検出する図外の温度センサの検出情報に基づいて第１冷媒調整弁１０の開度等を調整することにより、温調対象流体Ｐの一部を例えば１９．５℃±０．１℃程度の所望温度に温調させる。このとき、例えば、温調流体用加熱部Ｂ１を通過する前の温調対象流体Ｐの一部の温度は、１７℃±１℃程度とされており、温調流体用加熱部Ｂ１を通過したあとの温調対象流体Ｐの温度は、１９．５℃±０．１℃程度とされている。また、温調流体用加熱部Ｂ１に供給される冷媒Ａ１の温度は、７０℃程度とされている。 The temperature adjustment target fluid P is cooled by the evaporator 4 and then flows through the duct 12 so that the entire amount of the temperature adjustment target fluid P is introduced into the heating heat exchanger B.
The temperature control target fluid P (a part of the temperature control target fluid P) introduced through the duct 12 and introduced into the heating heat exchanger B is heated to a desired temperature by the refrigerant A1 in the temperature control fluid heating section B1. It is heated up to precisely. For example, adjusting the opening degree or the like of the first refrigerant adjustment valve 10 based on detection information of a temperature sensor (not shown) that detects the temperature of a part of the temperature adjustment target fluid P that has passed through the heating part B1 for temperature adjustment fluid. Thus, the temperature of a part of the temperature adjustment target fluid P is adjusted to a desired temperature of, for example, about 19.5 ° C. ± 0.1 ° C. At this time, for example, the temperature of part of the temperature adjustment target fluid P before passing through the temperature adjustment fluid heating unit B1 is about 17 ° C. ± 1 ° C., and has passed through the temperature adjustment fluid heating unit B1. The temperature of the subsequent temperature control target fluid P is about 19.5 ° C. ± 0.1 ° C. The temperature of the refrigerant A1 supplied to the temperature control fluid heating unit B1 is about 70 ° C.

一方、ダクト１２内の下方を通流して加熱用熱交換器Ｂに導入された温調対象流体Ｐ（温調対象流体Ｐの他部）は、加熱部Ｂ２ａにて冷媒Ａ２により所望温度にまで加熱される。例えば、加熱部Ｂ２ａを通過した温調対象流体Ｐの他部の温度を検出する図外の温度センサの検出情報に基づいて第２冷媒調整弁１１の開度等を調整することにより、温調対象流体Ｐの他部を例えば２０±０．１℃の所望温度に加熱させる。このとき、例えば、加熱部Ｂ２ａに供給される温調対象流体Ｐの他部の温度は、１７℃±１℃程度とされ、加熱部Ｂ２ａを通過したあと、冷却部Ｂ２ｂに供給される温調対象流体Ｐの他部の温度は、２０℃±０．１℃程度とされている。また、例えば、加熱部Ｂ２ａに供給される冷媒Ａ２の温度は、７０℃程度とされている。
そして、加熱部Ｂ２ａにて加熱された温調対象流体Ｐの他部は、冷却部Ｂ２ｂにて別温調対象流体Ｑを所望温度にまで冷却させる。このとき、例えば、加熱部Ｂ２ａを通過したあと、冷却部Ｂ２ｂに供給される温調対象流体Ｐの他部の温度は、２０℃±０．１℃程度とされ、冷却部Ｂ２ｂを通過したあとの温調対象流体Ｐの他部の温度は、２２℃±０．１℃程度とされている。さらに、例えば、冷却部Ｂ２ｂに供給される別温調対象流体Ｑの温度は２２℃とし、冷却部Ｂ２ｂを通過した別温調対象流体Ｑの温度は１８℃とされている。 On the other hand, the temperature control target fluid P (the other part of the temperature control target fluid P) that has flowed downward in the duct 12 and introduced into the heat exchanger B for heating reaches the desired temperature by the refrigerant A2 in the heating unit B2a. Heated. For example, the temperature adjustment is performed by adjusting the opening degree of the second refrigerant adjustment valve 11 based on detection information of a temperature sensor (not shown) that detects the temperature of the other part of the temperature adjustment target fluid P that has passed through the heating unit B2a. The other part of the target fluid P is heated to a desired temperature of 20 ± 0.1 ° C., for example. At this time, for example, the temperature of the other part of the temperature adjustment target fluid P supplied to the heating unit B2a is about 17 ° C. ± 1 ° C. After passing through the heating unit B2a, the temperature control supplied to the cooling unit B2b The temperature of the other part of the target fluid P is about 20 ° C. ± 0.1 ° C. Further, for example, the temperature of the refrigerant A2 supplied to the heating unit B2a is about 70 ° C.
The other part of the temperature adjustment target fluid P heated by the heating part B2a cools the separate temperature adjustment target fluid Q to a desired temperature by the cooling part B2b. At this time, for example, after passing through the heating part B2a, the temperature of the other part of the temperature adjustment target fluid P supplied to the cooling part B2b is about 20 ° C. ± 0.1 ° C. After passing through the cooling part B2b The temperature of the other part of the temperature control target fluid P is about 22 ° C. ± 0.1 ° C. Further, for example, the temperature of the separate temperature adjustment target fluid Q supplied to the cooling unit B2b is 22 ° C., and the temperature of the separate temperature adjustment target fluid Q that has passed through the cooling unit B2b is 18 ° C.

次に、温調流体用加熱部Ｂ１を通過する、或いは通過した温調対象流体Ｐの一部と、冷却部Ｂ２ｂを通過した温調対象流体Ｐの他部とは、加熱用熱交換器Ｂにおいて、或いは、加熱用熱交換器Ｂを通過したあと空調対象空間Ｋに供給されるまでの間における通風路において混合される。また、温調流体用加熱部Ｂ１を通過した温調対象流体Ｐの一部が温調流体用加熱部Ｂ１から受ける熱量Ｘに対して、冷却部Ｂ２ｂを通過した温調対象流体Ｐの他部が冷却部Ｂ２ｂから受ける熱量は比較的少ない（図２の場合では、熱量Ｘに対する熱量Ｙの比は、Ｙ／Ｘ＝１／３０程度である）。したがって、加熱用熱交換器Ｂを通過した温調対象流体Ｐの一部と他部とが混合された温調対象流体Ｐとなって、空調対象空間Ｋに供給される当該温調対象流体Ｐの温度は、温調対象流体Ｐの他部の影響を殆ど受けることなく、所望の温度である２０℃±０．１℃に精密に温調される。   Next, a part of the temperature adjustment target fluid P that passes through or has passed through the temperature adjustment fluid heating part B1 and the other part of the temperature adjustment target fluid P that has passed through the cooling part B2b are heated heat exchanger B Or after passing through the heat exchanger B for heating, the air is mixed in the ventilation path before being supplied to the air-conditioning target space K. The other part of the temperature adjustment target fluid P that has passed through the cooling unit B2b with respect to the amount of heat X received from the temperature adjustment fluid heating unit B1 by a part of the temperature adjustment target fluid P that has passed through the temperature adjustment fluid heating unit B1. Receives a relatively small amount of heat from the cooling part B2b (in the case of FIG. 2, the ratio of the amount of heat Y to the amount of heat X is about Y / X = 1/30). Therefore, the temperature adjustment target fluid P supplied to the air-conditioning target space K becomes a temperature adjustment target fluid P in which a part of the temperature adjustment target fluid P that has passed through the heat exchanger B for heating and other portions are mixed. The temperature is precisely controlled to a desired temperature of 20 ° C. ± 0.1 ° C. without being substantially affected by the other part of the temperature control target fluid P.

よって、本発明に係る温度調整装置Ｄでは、温調対象流体Ｐを精密に温調することに加えて、温度調整装置Ｄが発生する熱を別の用途でも利用可能としながら、温度調整装置Ｄの構成の小型化を実現することが可能となる。   Therefore, in the temperature adjusting device D according to the present invention, in addition to accurately adjusting the temperature of the temperature adjustment target fluid P, the temperature adjusting device D can be used for other purposes while the heat generated by the temperature adjusting device D can be used. It is possible to reduce the size of the configuration.

例えば、加熱用熱交換器Ｂにおいて、温調流体用加熱部Ｂ１、加熱部Ｂ２ａ及び冷却部Ｂ２ｂの配置を適宜変更することも可能である。例えば、図３に示すように、加熱用熱交換器Ｂの側面視において、当該加熱用熱交換器Ｂにおける上部及び下部に温調流体用加熱部Ｂ１をそれぞれ設け、これら温調流体用加熱部Ｂ１の上下方向間に別温調対象流体用の加熱部Ｂ２ａ及び冷却部Ｂ２ｂを設けて構成することもできる。この温調流体用加熱部Ｂ１は、加熱用熱交換器Ｂにおいて温調対象流体Ｐが通流する全体に対して過半数以上の部位に配置されている。なお、この加熱部Ｂ２ａは温調対象流体Ｐの通流方向の上流側、冷却部Ｂ２ｂは下流側に配置されている。
このように構成することにより、加熱部Ｂ２ａ及び冷却部Ｂ２ｂを通過した温調対象流体Ｐの他部と、温調流体用加熱部Ｂ１を通過して精密に温調された温調対象流体Ｐの一部とを混合して、温調対象流体Ｐの他部の影響により、空調対象空間Ｋに供給される温調対象流体Ｐの温度が所望温度（２０℃±０．１℃）となることが阻害されないように構成することができる。 [Another embodiment]
(1) In the above embodiment, the heating heat exchanger B is provided with the heating part B1 for temperature adjustment fluid at the upper part, and the heating part B2a and the cooling part B2b for another temperature adjustment target fluid are provided at the lower part. It is not necessarily limited to this configuration.
For example, in the heat exchanger B for heating, it is also possible to appropriately change the arrangement of the heating unit B1 for temperature control fluid, the heating unit B2a, and the cooling unit B2b. For example, as shown in FIG. 3, in the side view of the heat exchanger B for heating, a heating unit for temperature control fluid B <b> 1 is provided at the upper part and the lower part of the heating heat exchanger B, respectively. A heating unit B2a and a cooling unit B2b for another temperature adjustment target fluid may be provided between the upper and lower directions of B1.

The temperature of the temperature adjustment target fluid P supplied to the air conditioning target space K becomes a desired temperature (20 ° C. ± 0.1 ° C.) due to the influence of the other part of the temperature adjustment target fluid P. It can be configured so that it is not inhibited.

（２）上記実施形態では、加熱用熱交換器Ｂにおける別温調対象流体用の加熱部Ｂ２ａ及び冷却部Ｂ２ｂを設けて、当該冷却部Ｂ２ｂにおいて別温調対象流体Ｑを冷却する構成としたが、当該冷却部Ｂ２ｂを、別温調対象流体加熱部Ｂ２ｂ（温調部の一例）として用いて、別温調対象流体Ｑを加熱する構成とすることもできる。この場合、第２冷媒調整弁１１の開度等を調整して加熱部Ｂ２ａに供給される冷媒Ａ２（第２加熱用流体）の流量を調整することにより、加熱部Ｂ２ａを通過する温調対象流体Ｐの他部を加熱する。そして、別温調対象流体加熱部Ｂ２ｂにおいて、加熱部Ｂ２ａにて加熱された温調対象流体Ｐの他部と別温調対象流体Ｑとを熱交換させ、当該別温調対象流体Ｑを加熱する構成とすることができる。
例えば、加熱部Ｂ２ａに供給される温調対象流体Ｐの他部の温度は、１７℃±１℃程度とされ、加熱部Ｂ２ａを通過したあとの、別温調対象流体加熱部Ｂ２ｂに供給される温調対象流体Ｐの他部の温度は、２４℃±０．１℃程度とされ、さらに、別温調対象流体加熱部Ｂ２ｂを通過したあとの温調対象流体Ｐの他部の温度は、２２℃±０．１℃程度とされる。また、例えば、別温調対象流体加熱部Ｂ２ｂに供給される別温調対象流体Ｑの温度は２０℃とし、別温調対象流体加熱部Ｂ２ｂを通過した別温調対象流体Ｑの温度は２２℃とされている。なお、この場合であっても、上記実施形態と同様に、加熱用熱交換器Ｂを通過した温調対象流体Ｐの一部と他部とが混合された温調対象流体Ｐとなって、空調対象空間Ｋに供給される当該温調対象流体Ｐの温度は、温調対象流体Ｐの他部の影響を殆ど受けることなく、所望の温度である２０℃±０．１℃に精密に温調される。 (2) In the above embodiment, the heating unit B2a and the cooling unit B2b for the separate temperature adjustment target fluid in the heating heat exchanger B are provided, and the separate temperature adjustment target fluid Q is cooled in the cooling unit B2b. However, the cooling unit B2b can be used as another temperature adjustment target fluid heating unit B2b (an example of a temperature adjustment unit) to heat the separate temperature adjustment target fluid Q. In this case, the temperature adjustment target passing through the heating part B2a by adjusting the flow rate of the refrigerant A2 (second heating fluid) supplied to the heating part B2a by adjusting the opening degree of the second refrigerant regulating valve 11 and the like. The other part of the fluid P is heated. Then, in the separate temperature adjustment target fluid heating part B2b, heat exchange is performed between the other part of the temperature adjustment target fluid P heated by the heating part B2a and the separate temperature adjustment target fluid Q, and the separate temperature adjustment target fluid Q is heated. It can be set as the structure to do.
For example, the temperature of the other part of the temperature adjustment target fluid P supplied to the heating part B2a is about 17 ° C. ± 1 ° C., and is supplied to the separate temperature adjustment target fluid heating part B2b after passing through the heating part B2a. The temperature of the other part of the temperature control target fluid P is about 24 ° C. ± 0.1 ° C. Further, the temperature of the other part of the temperature control target fluid P after passing through the separate temperature control target fluid heating part B2b is , About 22 ° C. ± 0.1 ° C. Further, for example, the temperature of the separate temperature adjustment target fluid Q supplied to the separate temperature adjustment target fluid heating unit B2b is 20 ° C., and the temperature of the separate temperature adjustment target fluid Q that has passed through the separate temperature adjustment target fluid heating unit B2b is 22 It is said to be ℃. Even in this case, as in the above embodiment, the temperature adjustment target fluid P is a mixture of a part of the temperature adjustment target fluid P that has passed through the heating heat exchanger B and the other portion, The temperature of the temperature adjustment target fluid P supplied to the air-conditioning target space K is precisely warmed to a desired temperature of 20 ° C. ± 0.1 ° C. without being affected by the other parts of the temperature adjustment target fluid P. It is adjusted.

（３）上記実施形態では、蒸発器４を冷却用熱交換器として用いて、蒸発器４を通流する冷媒Ａにより温調対象流体Ｐを直接冷却する構成としたが、この構成に制限されるものではない。すなわち、蒸発器４の冷熱を間接的に熱源として用いて温調対象流体Ｐを冷却することもできる。
例えば、蒸発器４を通流する冷媒Ａと熱交換して冷熱を取得する（冷却される）熱伝達用液体を循環させる液体回路を設け、この液体回路において冷熱を取得した熱伝達用液体と温調対象流体Ｐとを熱交換して、当該温調対象流体Ｐを冷却する冷却用熱交換器を設けるように構成することができる。これにより、蒸発器４において、冷媒Ａにて温調対象流体Ｐを直接冷却させるのではなく、冷媒Ａにて熱伝達用液体を冷却させ、当該熱伝達用液体により間接的に温調対象流体Ｐを冷却することができる。そして、熱伝達用液体は、冷媒と比べて比重が大きいので、熱伝達用液体と温調対象流体Ｐとを熱交換させる際に、熱伝達用液体の温度を均一にすることができる。よって、温調対象流体Ｐを温度むらがなく均一な温度に冷却することができる。 (3) In the above embodiment, the evaporator 4 is used as a cooling heat exchanger, and the temperature adjustment target fluid P is directly cooled by the refrigerant A flowing through the evaporator 4. However, the configuration is limited to this configuration. It is not something. That is, the temperature adjustment target fluid P can be cooled by indirectly using the cold heat of the evaporator 4 as a heat source.
For example, a liquid circuit that circulates a heat transfer liquid that acquires (cools) heat by exchanging heat with the refrigerant A flowing through the evaporator 4, and the heat transfer liquid that has acquired the cold in this liquid circuit, A heat exchanger for cooling that cools the temperature control target fluid P by exchanging heat with the temperature control target fluid P can be provided. Thus, in the evaporator 4, the temperature adjustment target fluid P is not directly cooled by the refrigerant A, but the heat transfer liquid is cooled by the refrigerant A, and the temperature adjustment target fluid is indirectly indirectly cooled by the heat transfer liquid. P can be cooled. And since the specific gravity of the heat transfer liquid is larger than that of the refrigerant, the heat transfer liquid can be made uniform in temperature when the heat transfer liquid and the temperature control target fluid P are subjected to heat exchange. Therefore, the temperature control target fluid P can be cooled to a uniform temperature without temperature unevenness.

（４）上記実施形態では、第１加熱用流体としての冷媒Ａ１及び第２加熱用流体としての冷媒Ａ２を、同一の冷媒Ａにより構成したが、温調対象流体Ｐを適切に温調（例えば、加熱）することができる構成であれば、この構成に限定されるものではない。例えば、第１加熱用流体及び第２加熱用流体のそれぞれを異なる流体を用いて構成することも可能である。 (4) In the above embodiment, the refrigerant A1 as the first heating fluid and the refrigerant A2 as the second heating fluid are configured by the same refrigerant A, but the temperature adjustment target fluid P is appropriately temperature-controlled (for example, The structure is not limited to this as long as it can be heated. For example, each of the first heating fluid and the second heating fluid can be configured using different fluids.

（５）上記実施形態において、別温調対象流体Ｑを圧縮空気としているが、温調対象流体Ｐと別温調対象流体Ｑとは別の流体であればよく、例えば、各種機器を冷却するために用いる冷却水を別温調対象流体Ｑとすることも可能である。これにより、冷却用熱交換器にて取得した冷熱を各種機器を冷却する用途に用いることができる。 (5) In the above embodiment, the separate temperature adjustment target fluid Q is compressed air, but the temperature adjustment target fluid P and the separate temperature adjustment target fluid Q may be different fluids, for example, various devices are cooled. Therefore, it is possible to use the cooling water used for this purpose as the separate temperature adjustment target fluid Q. Thereby, the cold energy acquired with the heat exchanger for cooling can be used for the use which cools various apparatuses.

（６）上記実施形態では、本発明に係る温度調整装置Ｄとして、空調対象空間Ｋとの間で温調対象流体Ｐを循環して空調対象空間Ｋを温調するものを例示したが、例えば、温度調整装置Ｄは、空調対象空間Ｋとの間で循環される温調対象流体Ｐに外気を取り入れて、その外気を取り入れた温調対象流体Ｐを温調して空調対象空間Ｋに供給するように構成することもでき、温度調整装置Ｄがどのような流体を温調対象流体Ｐとするかについては適宜変更が可能である。 (6) In the above embodiment, as the temperature adjustment device D according to the present invention, the temperature adjustment target fluid P is circulated between the air conditioning target space K and the air conditioning target space K is temperature-controlled. The temperature adjustment device D takes outside air into the temperature adjustment target fluid P circulated between the air conditioning target space K, supplies the air to the air conditioning target space K after adjusting the temperature of the temperature adjustment target fluid P taking in the outside air. It can also be configured, and it is possible to appropriately change what kind of fluid the temperature adjustment device D uses as the temperature adjustment target fluid P.

（７）上記実施形態では、加熱用熱交換器Ｂと冷却用熱交換器（蒸発器４）との間に、温調対象流体Ｐの全量を通流させるダクト１２を設けたが、このダクト１２を省略する構成としてもよい。例えば、温調対象流体Ｐの通流方向において冷却用熱交換器と加熱用熱交換器Ｂとが接触或いは近接して配置されている場合等には、上記ダクト１２を省略した構成とすることができる。 (7) In the above embodiment, the duct 12 is provided between the heating heat exchanger B and the cooling heat exchanger (evaporator 4) to allow the entire amount of the temperature control target fluid P to flow. 12 may be omitted. For example, when the cooling heat exchanger and the heating heat exchanger B are arranged in contact with or close to each other in the flow direction of the temperature control target fluid P, the duct 12 is omitted. Can do.
