Description
本發明是有關於一種空氣調和裝置。The invention relates to an air conditioning device.
作為於半導體製造設備等中所使用的精密溫調用的空氣調和裝置，有以下空氣調和裝置：具備具有空氣取入口及空氣噴出口的框體，於該框體內收容送風機、加熱部及冷卻部。關於此種空氣調和裝置，藉由送風機的驅動將空氣自裝置外部取入至空氣取入口，並藉由加熱部及冷卻部將所取入的空氣調節為所期望的溫度而由空氣噴出口噴出。空氣取入口及空氣噴出口可設置於框體的任意位置，於多數情況下，空氣取入口設置於框體的側面，空氣噴出口設置於框體的上表面或側面（例如，參照專利文獻1）。As a precision warm air conditioning device used in semiconductor manufacturing equipment and the like, there is an air conditioning device including a housing having an air inlet and an air outlet, and a blower, a heating unit, and a cooling unit are housed in the housing. With regard to this type of air conditioning device, air is taken in from the outside of the device to an air inlet by the drive of a blower, and the taken-in air is adjusted to a desired temperature by a heating portion and a cooling portion, and is ejected from an air outlet . The air inlet and the air outlet can be provided at any position of the frame. In most cases, the air inlet is provided on the side of the frame, and the air outlet is provided on the upper surface or side of the frame (for example, refer to Patent Document 1). ).
此種空氣調和裝置通常用以藉由將管道連接於空氣噴出口來將經溫度控制的空氣經由管道而供給至溫度控制對象空間。另外，亦有以下情況：將具有多個孔的中空的箱連接於管道的下游側端部，並將分支用的管道連接於該箱的多個孔，藉此將經溫度控制的空氣供給至多個溫度控制對象空間。例如，於半導體製造設備中，有以下情況：藉由使用如上所述的箱而將由一個空氣調和裝置噴出的空氣分配於潔淨室及設置於該潔淨室內的多個裝置的內部等。Such an air-conditioning apparatus is generally used to supply temperature-controlled air to a temperature-control target space through a duct by connecting a duct to an air spout. In addition, there may be a case where a hollow box having a plurality of holes is connected to a downstream end portion of a pipe, and a branch pipe is connected to a plurality of holes of the box, thereby supplying temperature-controlled air at most. Space for temperature control objects. For example, in a semiconductor manufacturing facility, there is a case where the air ejected from one air conditioner is distributed to the inside of a clean room and a plurality of devices installed in the clean room by using a box as described above.
另外，於在半導體製造設備中使用時，此種空氣調和裝置有時配置於設置所述設備的空間的下一級的空間。於該情況下，連接於空氣噴出口的管道是以朝向上一級的空間而朝上方延伸的方式配置。 [現有技術文獻] [專利文獻]In addition, when used in a semiconductor manufacturing facility, such an air-conditioning apparatus may be arranged in a space below the space in which the facility is installed. In this case, the duct connected to the air ejection outlet is arranged so as to extend upward toward the space of the upper stage. [Prior Art Literature] [Patent Literature]
[專利文獻1]日本專利特開2009-63242號公報[Patent Document 1] Japanese Patent Laid-Open No. 2009-63242
[發明所欲解決的課題] 然而，專利文獻1中所揭示的空氣調和裝置中，於框體的上表面或側面設置有一個空氣噴出口，但該構成中，於將管道自空氣噴出口朝向溫度控制對象空間延伸的情況下，可產生不期望地必須使管道過多地彎曲的狀況。因此，有以下情況：因由管道的彎曲部分的增加所引起的壓力損失的增加，而產生不期望地必須使用以獲得所期望的風量的送風機的輸出增加的狀況，送風機的運轉效率降低。具體而言，例如於將空氣噴出口設置於框體的側面且使溫度控制對象空間相對於空氣調和裝置而位於上方的情況下，需要使管道朝上方彎曲。該情況與使管道直線性延伸的情況相比較，壓力損失增加，因此送風機的運轉效率降低。[Problems to be Solved by the Invention] However, in the air-conditioning apparatus disclosed in Patent Document 1, an air outlet is provided on the upper surface or side of the housing. However, in this configuration, the duct is directed from the air outlet When the temperature control target space is extended, a situation in which the pipe must be undesirably bent excessively may occur. Therefore, there is a case where the output of the blower increases undesirably and must be used to obtain a desired air volume due to an increase in pressure loss caused by an increase in the bent portion of the pipe, and the operation efficiency of the blower is reduced. Specifically, for example, when the air outlet is provided on the side of the housing and the temperature control target space is positioned above the air conditioner, the duct needs to be bent upward. In this case, as compared with the case where the duct is linearly extended, the pressure loss increases, and therefore the operation efficiency of the blower is reduced.
另外，此種空氣調和裝置中，作為連接於空氣噴出口的管道，通常使用與空氣噴出口的直徑吻合的直徑的管道。此處，如專利文獻1所揭示般，於裝置的上表面或側面僅設置一個空氣噴出口的構成中，有以下情況：根據設置條件，而管道的佔有區域會不期望地變大，產生空氣調和裝置的設置自由度受到制約的狀況或該裝置的周邊構件的配置自由度受到制約的狀況。另外，相對於溫度控制對象空間所要求的要求風量，管道變得過小，藉此亦可產生不期望地必須使送風機的輸出增加的狀況。In addition, in such an air-conditioning apparatus, as the pipe connected to the air ejection port, a pipe having a diameter that matches the diameter of the air ejection port is generally used. Here, as disclosed in Patent Document 1, in a configuration in which only one air ejection port is provided on the upper surface or the side of the device, there are cases in which the occupied area of the duct becomes undesirably large and air is generated depending on the installation conditions. A situation in which the degree of freedom in setting the blending device is restricted or a situation in which the degree of freedom in arranging the peripheral members of the unit is restricted. In addition, the duct becomes too small with respect to the required air volume required for the temperature-control target space, whereby a situation in which the output of the blower must be increased undesirably may also occur.
另外，於將空氣自空氣調和裝置供給至多個溫度控制對象空間時，如上所述，可將具有多個孔的中空的箱連接於與空氣噴出口連接的管道的下游側端部，且將分支用的管道連接於該箱的多個孔。然而，於該情況下，產生由管道的增加所引起的成本上升及構成的複雜化的問題。因此，期望不使結構複雜化而可將空氣供給至多個空間的構成。In addition, when supplying air from the air conditioner to a plurality of temperature control target spaces, as described above, a hollow box having a plurality of holes can be connected to the downstream side end of the pipe connected to the air outlet, and branched. A pipe is connected to the holes of the box. However, in this case, there arises a problem that the cost increases and the structure becomes complicated due to an increase in the number of pipes. Therefore, a structure capable of supplying air to a plurality of spaces without complicating the structure is desired.
本發明是考慮所述實際情況而成者，其目的在於提供一種可以多種型式連接用以向溫度控制對象空間供給空氣的管道，且可根據狀況而靈活地設定較佳的管道的配置型式的空氣調和裝置。 [解決課題的手段]The present invention has been made in consideration of the above-mentioned actual situation, and an object thereof is to provide a duct that can be connected to a plurality of types to supply air to a temperature-control target space, and a preferred arrangement type of air can be flexibly set according to the situation.

According to this configuration, when it is required to reduce the occupied area of the pipe, by connecting a thin pipe to the first pipe connection hole with a small opening area, it is possible to respond to the requirement for suppressing the occupied area and the required space for the temperature control object. When a large air volume is required, by connecting a thick pipe to the first pipe connection hole with a large opening area, it is possible to suppress an undesired increase in the output of the blower caused by a pressure loss, and to supply air to the temperature-controlled space . Thereby, it is possible to further flexibly set a better pipe arrangement type according to the situation, and convenience can be improved.

於該情況下，多個所述第2管道連接孔中的至少一個（一部分）第2管道連接孔亦可朝與其他第2管道連接孔不同的方向開口。 根據該構成，例如於將所連接的管道延伸至溫度控制對象空間時，可根據溫度控制對象空間的位置，自彼此朝不同的方向開口的多個第2管道連接孔中適宜選擇於所述情況下可極力抑制管道的長度的管道連接孔。藉此，可根據狀況而進一步靈活地設定較佳的管道的配置型式，且可提高便利性。In this case, at least one (a part) of the plurality of second pipe connection holes may open the second pipe connection hole in a direction different from that of the other second pipe connection holes.

其次，參照圖2對冷卻部2及加熱部4進行說明。首先，對冷卻部2進行說明，本實施形態中的冷卻部2包含第1冷卻單元10的冷卻環管14與第2冷卻單元20的冷卻環管24。於本實施形態中，包含冷卻環管14的第1冷卻單元10是藉由如下方式而構成：藉由配管15將以可變運轉頻率運轉且可調節轉速的壓縮機11、凝結器12、膨脹閥13及冷卻環管14依該順序連接以使熱媒體循環，包含冷卻環管24的第2冷卻單元20是藉由如下方式而構成：藉由配管25將以可變運轉頻率運轉且可調節轉速的壓縮機21、凝結器22、膨脹閥23及冷卻環管24依該順序連接以使熱媒體循環。Next, the cooling section 2 and the heating section 4 will be described with reference to FIG. 2. First, the cooling unit 2 will be described. The cooling unit 2 in this embodiment includes a cooling ring pipe 14 of the first cooling unit 10 and a cooling ring pipe 24 of the second cooling unit 20. In the present embodiment, the first cooling unit 10 including the cooling loop 14 is configured by a compressor 15, a condenser 12, and an expansion device that are operated at a variable operating frequency and whose rotation speed is adjustable by a pipe 15. The valve 13 and the cooling loop 14 are connected in this order to circulate the heat medium. The second cooling unit 20 including the cooling loop 24 is configured as follows: The pipe 25 will be operated at a variable operating frequency and adjustable. The compressor 21, the condenser 22, the expansion valve 23, and the cooling ring 24 are connected in this order in order to circulate the heat medium.
於該些第1冷卻單元10及第2冷卻單元20中，壓縮機11、21將自冷卻環管14、24流出的低溫且低壓的氣體狀態的熱媒體壓縮，成為高溫且高壓的氣體狀態，而供給至凝結器12、22。壓縮機11、21是以可變運轉頻率運轉且根據運轉頻率而可調節轉速的反相器壓縮機。壓縮機11、21中，運轉頻率越高，可將更多的熱媒體供給至凝結器12、22。作為壓縮機11，較佳為採用一體具有反相器與馬達的渦卷型壓縮機。然而，只要是藉由利用反相器調節運轉頻率來進一步調節轉速而可調節熱媒體的供給量（流量），則壓縮機11、21的形式並無特別限定。In the first cooling unit 10 and the second cooling unit 20, the compressors 11, 21 compress the low-temperature and low-pressure gas heat medium flowing from the cooling loops 14, 24 to a high-temperature and high-pressure gas state. It is supplied to the condensers 12 and 22. The compressors 11 and 21 are inverter compressors that operate at a variable operating frequency and whose rotation speed can be adjusted according to the operating frequency. The higher the operating frequency of the compressors 11 and 21, the more heat medium can be supplied to the condensers 12 and 22. As the compressor 11, a scroll-type compressor having an inverter and a motor as a whole is preferably used. However, the form of the compressors 11 and 21 is not particularly limited as long as the supply amount (flow rate) of the heat medium can be adjusted by further adjusting the rotation speed by adjusting the operating frequency using an inverter.
另外，凝結器12、22是藉由冷卻水將經壓縮機11、21壓縮的熱媒體冷卻同時加以凝結，成為規定的冷卻溫度的高壓的液體狀態而供給至膨脹閥13、23。凝結器12、22的冷卻水可使用水，亦可使用其他冷媒。另外，膨脹閥13、23是藉由使由凝結器12、22供給的熱媒體膨脹而使其減壓，成為低溫且低壓的氣液混合狀態而供給至冷卻環管14、24。冷卻環管14、24是使所供給的熱媒體與溫度控制對象的空氣進行熱交換而對空氣進行冷卻。與空氣進行熱交換的熱媒體成為低溫且低壓的氣體狀態而自冷卻環管14、24流出並再次被壓縮機11、21壓縮。In addition, the condensers 12 and 22 cool and heat the heat medium compressed by the compressors 11 and 21 while condensing with cooling water, and supply the expansion valves 13 and 23 with a high-pressure liquid state having a predetermined cooling temperature. The cooling water of the condensers 12 and 22 may be water or other refrigerants. In addition, the expansion valves 13 and 23 are supplied to the cooling loops 14 and 24 by expanding the heat medium supplied from the condensers 12 and 22 to depressurize them to a low-temperature and low-pressure gas-liquid mixed state. The cooling loops 14 and 24 cool the air by exchanging heat with the supplied heat medium and the air to be temperature-controlled. The heat medium that exchanges heat with air becomes a low-temperature and low-pressure gas state, flows out of the cooling loops 14, 24, and is compressed by the compressors 11, 21 again.
如上所述的各冷卻單元10、20中，藉由使壓縮機11、21的運轉頻率發生變化來調節轉速，可調節供給至凝結器12、22的熱媒體的供給量，並且可調節膨脹閥13、23的開度，藉此可調節供給至冷卻環管14、24的熱媒體的供給量。藉由進行此種調節而使冷凍能力成為可變。再者，本實施形態中，出於提高控制的穩定性的目的，第1冷卻單元10的壓縮機11以一定的頻率運轉。於實施此種運轉的情況下，壓縮機11可為以固定頻率運轉的壓縮機，於該情況下，可減低製造成本。In each of the cooling units 10 and 20 described above, the rotation frequency is adjusted by changing the operating frequency of the compressors 11 and 21 to adjust the supply amount of the heat medium supplied to the condensers 12 and 22 and the expansion valve can be adjusted. The openings of 13, 23 can adjust the supply amount of the heat medium supplied to the cooling loops 14, 24. By performing such adjustment, the freezing capacity becomes variable. Furthermore, in the present embodiment, the compressor 11 of the first cooling unit 10 is operated at a constant frequency for the purpose of improving the stability of the control. When such an operation is performed, the compressor 11 may be a compressor that operates at a fixed frequency. In this case, the manufacturing cost can be reduced.
另外，對冷卻部2的配置態樣進行詳細敘述，本實施形態中，如圖2所示，於空氣流通路30內設置有沿空氣的流動延伸而將空氣流通路30的一部分二分割的分隔構件200，藉由分隔構件200將空氣流通路30的一部分劃分為第1流路30A與第2流路30B。然後，於第1流路30A設置有冷卻部2。另外，於分隔構件200的下游側的端部設置有對第1流路30A及第2流路30B的開度進行調節的流量調節擋板201。另一方面，於空氣取入口31內設置有上游側溫度感測器44，上游側溫度感測器44對與來自折回流路100的空氣合流的取入至空氣取入口31後的空氣的溫度進行檢測。此處，本實施形態中的流量調節擋板201是根據上游側溫度感測器44所檢測的溫度而被控制單元50控制，藉此可調節第1流路30A及第2流路30B的開度。In addition, the arrangement of the cooling unit 2 will be described in detail. In this embodiment, as shown in FIG. 2, an air flow path 30 is provided with a partition that extends along the flow of the air and divides a part of the air flow path 30 in two. In the member 200, a part of the air flow path 30 is divided into a first flow path 30A and a second flow path 30B by the partition member 200. A cooling unit 2 is provided in the first flow path 30A. In addition, a flow rate adjusting baffle 201 that adjusts the opening degree of the first flow path 30A and the second flow path 30B is provided at an end portion on the downstream side of the partition member 200. On the other hand, an upstream temperature sensor 44 is provided in the air intake port 31. The upstream temperature sensor 44 measures the temperature of the air taken into the air intake port 31 in conjunction with the air from the recirculation path 100. Check it out. Here, the flow adjustment baffle 201 in the present embodiment is controlled by the control unit 50 based on the temperature detected by the upstream-side temperature sensor 44, whereby the opening of the first flow path 30A and the second flow path 30B can be adjusted. degree.
其次，對加熱部4進行說明，本實施形態中的加熱部4具有如下結構：使自第1冷卻單元10中的壓縮機11朝向凝結器12流出的熱媒體的一部分分支，經由加熱環管16及設置於其下游側的加熱量調節閥18而以流入至位於壓縮機11的下游側的凝結器12的方式返回。此處，加熱環管16收容於空氣流通路30內。Next, the heating unit 4 will be described. The heating unit 4 in this embodiment has a structure in which a part of the heat medium flowing from the compressor 11 in the first cooling unit 10 toward the condenser 12 is branched and passes through the heating loop 16 And the heating amount adjustment valve 18 provided on the downstream side thereof, and returns to the condenser 12 located on the downstream side of the compressor 11. Here, the heating loop 16 is accommodated in the air flow path 30.
詳細而言，加熱環管16具有熱媒體入口與熱媒體出口，熱媒體入口和壓縮機11與凝結器12之間的配管的上游側是藉由其他配管而連接，熱媒體出口和壓縮機11與凝結器12之間的配管的下游側進而藉由其他配管而連接。然後，於自熱媒體出口延伸的配管設置有加熱量調節閥18。藉此，加熱部4可使自壓縮機11朝向凝結器12流出的熱媒體的一部分分支，經由加熱環管16及加熱量調節閥18而以流入至凝結器12的方式返回。Specifically, the heating loop pipe 16 has a heat medium inlet and a heat medium outlet, and the upstream side of the pipe between the heat medium inlet and the compressor 11 and the condenser 12 is connected by another pipe. The heat medium outlet and the compressor 11 The downstream side of the piping to the condenser 12 is further connected by another piping. A piping extending from the heating medium outlet is provided with a heating amount adjustment valve 18. Thereby, the heating unit 4 can branch a part of the heat medium flowing out from the compressor 11 toward the condenser 12 and return to the condenser 12 through the heating loop 16 and the heating amount adjustment valve 18.
該加熱部4中，經壓縮機11壓縮的高溫且高壓的氣體狀態的熱媒體被供給至加熱環管16。加熱環管16使所供給的熱媒體與溫度控制對象的空氣進行熱交換而對空氣進行加熱。然後，與空氣進行熱交換的熱媒體自加熱環管16返回至壓縮機11與凝結器12之間的配管。此處，藉由加熱量調節閥18對來自加熱環管16的熱媒體的返回量進行調節，可變更加熱環管16的加熱能力。熱媒體的返回量越多，加熱能力越增加。此種加熱部4的加熱能力可根據壓縮機11的運轉頻率及/或加熱量調節閥18的開度而進行調節。In the heating unit 4, a high-temperature and high-pressure gas-state heat medium compressed by the compressor 11 is supplied to the heating loop 16. The heating loop 16 heats the supplied heat medium by exchanging heat with the air to be controlled by the temperature. Then, the heat medium that exchanges heat with air is returned from the heating loop 16 to the piping between the compressor 11 and the condenser 12. Here, the heating amount adjustment valve 18 is used to adjust the return amount of the heat medium from the heating loop 16 to change the heating capability of the heating loop 16. The more the heat medium is returned, the more the heating capacity is increased. The heating capacity of the heating unit 4 can be adjusted according to the operating frequency of the compressor 11 and / or the opening degree of the heating amount adjusting valve 18.

其次，對本實施形態的空氣調和裝置1的動作進行說明。本實施形態的空氣調和裝置1中，溫度控制對象的由空氣取入口31取入的空氣藉由冷卻部2而冷卻，藉由加熱部4而加熱，並朝向預先設定的目標溫度而進行控制。Next, the operation of the air-conditioning apparatus 1 according to this embodiment will be described. In the air-conditioning apparatus 1 of this embodiment, the air taken in by the air intake port 31 as a temperature control object is cooled by the cooling unit 2 and heated by the heating unit 4 and is controlled toward a preset target temperature.
於將本實施形態的空氣調和裝置1加以運轉時，首先，於控制單元50中，輸入目標溫度與目標濕度。另外，藉由驅動送風機60，空氣流通路30內的空氣流動至空氣噴出口32側，藉此自空氣流通路30的空氣取入口31取入溫度控制對象的空氣。進而，亦驅動各冷卻單元10、20的壓縮機11、21。另外，該例中，以使相對於送風機60輸出的風量的規定比例的風量的空氣自折回流路100返回至冷卻部2的上游側且加熱部4的上游側的位置的方式調節風量調節用擋板101的開度。進而，根據溫度控制對象空間的位置、數量、要求風量等而將管道120連接於第1管道連接孔91及第2管道連接孔92、93中的所期望的管道連接孔。When operating the air-conditioning apparatus 1 of this embodiment, first, the control unit 50 inputs a target temperature and a target humidity. In addition, by driving the blower 60, the air in the air flow path 30 flows to the air ejection outlet 32 side, thereby taking in the air to be temperature controlled from the air intake port 31 of the air flow path 30. Furthermore, the compressors 11 and 21 of the cooling units 10 and 20 are also driven. In this example, the air volume adjustment is performed so that air having a predetermined proportion of the air volume with respect to the air volume output from the blower 60 returns from the folding return path 100 to the upstream side of the cooling unit 2 and the upstream side of the heating unit 4. The opening degree of the baffle 101. Furthermore, the pipe 120 is connected to a desired pipe connection hole of the first pipe connection hole 91 and the second pipe connection holes 92 and 93 according to the position, number, required air volume, and the like of the temperature control target space.
如上所述般驅動送風機60等，由空氣流通路30的空氣取入口31取入的空氣經上游側溫度感測器44檢測出溫度後，首先，通過冷卻部2（第1流路30A）及/或第2流路30B，其後，通過加熱部4。其後，該空氣藉由加濕裝置70而加濕後，由空氣噴出口32噴出，到達至分配箱80的內部空間S。然後，空氣的一部分經由第1管道連接孔91及第2管道連接孔92、93的一部分或全部而供給至一個或多個管道120。另外，空氣的另一部分自第2管道連接孔94經由折回流路100而返回至冷卻部2的上游側且加熱部4的上游側的位置。此處，通過空氣噴出口32的空氣藉由溫度感測器41而檢測溫度，藉由濕度感測器42而檢測濕度。然後，溫度感測器41將所檢測的溫度輸出至控制單元50，濕度感測器42將所檢測的濕度輸出至控制單元50。The blower 60 and the like are driven as described above, and after the air taken in from the air inlet 31 of the air flow path 30 is detected by the upstream temperature sensor 44, it first passes through the cooling section 2 (the first flow path 30A) and The second flow path 30B passes through the heating unit 4 thereafter. After that, the air is humidified by the humidifying device 70 and then ejected from the air ejection port 32 and reaches the internal space S of the distribution box 80. Then, a part of the air is supplied to one or more pipes 120 through a part or all of the first pipe connection holes 91 and the second pipe connection holes 92 and 93. The other part of the air returns from the second duct connection hole 94 to the upstream side of the cooling unit 2 and the upstream side of the heating unit 4 via the return flow path 100. Here, the temperature of the air passing through the air outlet 32 is detected by the temperature sensor 41 and the humidity is detected by the humidity sensor 42. Then, the temperature sensor 41 outputs the detected temperature to the control unit 50, and the humidity sensor 42 outputs the detected humidity to the control unit 50.
然後，控制單元50基於溫度感測器41所檢測的溫度與目標溫度的差分，來控制加熱量調節閥18的開度、第1冷卻單元10的膨脹閥13的開度、第2冷卻單元20的膨脹閥23的開度及壓縮機21的運轉頻率，並以輸出與所述差分相對應的加熱能力及冷凍能力的方式進行控制。另外，控制單元50亦基於濕度感測器42所檢測的濕度與目標濕度的差分來控制加濕裝置70的加濕能力。Then, the control unit 50 controls the opening degree of the heating amount adjustment valve 18, the opening degree of the expansion valve 13 of the first cooling unit 10, and the second cooling unit 20 based on the difference between the temperature detected by the temperature sensor 41 and the target temperature. The opening degree of the expansion valve 23 and the operating frequency of the compressor 21 are controlled so as to output heating capacity and refrigeration capacity corresponding to the difference. In addition, the control unit 50 also controls the humidification capability of the humidification device 70 based on the difference between the humidity detected by the humidity sensor 42 and the target humidity.
然後，本實施形態中，經溫度控制的空氣經由第1管道連接孔91及第2管道連接孔92、93的一部分或全部而供給至一個或多個管道120，將經溫度控制的空氣自管道120供給至溫度控制對象空間。Then, in this embodiment, the temperature-controlled air is supplied to one or more pipes 120 through part or all of the first pipe connection hole 91 and the second pipe connection holes 92 and 93, and the temperature-controlled air is supplied from the pipe. 120 is supplied to the temperature control target space.
另外，於進行此種運轉時，本實施形態的空氣調和裝置1中，可藉由折回流路100，將通過冷卻部2及加熱部4的空氣的一部分供給至冷卻部2的上游側且加熱部4的上游側的位置，從而與取入至空氣流通路30的空氣取入口31前的空氣合流。藉此，即便為根據環境溫度的顯著變動而取入至空氣取入口31的外部空氣的溫度發生大幅變動的情況下，該外部空氣亦藉由與經溫度控制的來自折回流路100的空氣合流，而其溫度變得接近於應進行溫度控制的溫度。即，產生相對於環境變動的影響的影響緩和效果。因此，即便不根據外部空氣的溫度的大幅變動而使冷凍能力或加熱能力急劇發生大幅變化，亦可容易將與來自折回流路100的空氣合流的外部空氣控制為所期望的溫度。In addition, when performing such an operation, in the air conditioning apparatus 1 of the present embodiment, a part of the air passing through the cooling section 2 and the heating section 4 can be supplied to the upstream side of the cooling section 2 and heated by the return flow path 100. The position on the upstream side of the unit 4 merges with the air before the air intake port 31 taken into the air flow path 30. Thereby, even if the temperature of the outside air taken into the air intake port 31 changes greatly according to a significant change in the ambient temperature, the outside air merges with the temperature-controlled air from the recirculation path 100 , And its temperature becomes close to the temperature that should be temperature controlled. In other words, an influence mitigation effect is generated with respect to the influence of environmental changes. Therefore, it is possible to easily control the outside air that joins the air from the return flow path 100 to a desired temperature without drastically changing the freezing capacity or the heating capacity in response to a large change in the temperature of the outside air.
根據以上所說明的本實施形態的空氣調和裝置1，於將所連接的管道延伸至溫度控制對象空間時，可根據溫度控制對象空間的位置，自朝上方開口的第1管道連接孔91及朝與其不同的方向開口的第2管道連接孔92、93、94中適宜選擇於所述情況下可極力抑制管道的彎曲部分的管道連接孔。藉此，可抑制由管道所形成的不期望的彎曲部分所引起的壓力損失的增加，藉此可抑制送風機的運轉效率的降低。另外，於有多個溫度控制對象空間的情況下，藉由將自多個管道連接孔91、92、93、94中選擇並加以連接的管道延伸至相對應的溫度控制對象空間，可抑制管道的增加並且可將經溫度控制的空氣供給至多個溫度控制對象空間。因而，可以多種型式連接用以向溫度控制對象空間供給空氣的管道，且可根據狀況而靈活地設定較佳的管道的配置型式。According to the air-conditioning apparatus 1 of the present embodiment described above, when the connected duct is extended to the temperature control target space, the first duct connection holes 91 and the openings which are opened upward according to the position of the temperature control target space can be Among the second pipe connection holes 92, 93, and 94 that are opened in different directions, a pipe connection hole that can strongly suppress a bent portion of the pipe in the above case is appropriately selected. Thereby, it is possible to suppress an increase in pressure loss caused by an undesired bent portion formed by the duct, and thereby it is possible to suppress a decrease in the operation efficiency of the blower. In addition, when there is a plurality of temperature control target spaces, by selecting and connecting the pipes selected from the plurality of pipe connection holes 91, 92, 93, and 94 to the corresponding temperature control target space, the pipes can be suppressed. It can increase the temperature and supply temperature-controlled air to a plurality of temperature-controlled space. Therefore, it is possible to connect various types of pipes for supplying air to the temperature control target space, and it is possible to flexibly set a preferred arrangement type of the pipes according to the situation.
另外，於分配箱80設置有多個第1管道連接孔91，藉此可使可通過管道而直接供給空氣的溫度控制對象空間增加，因此可提高便利性。In addition, by providing a plurality of first duct connection holes 91 in the distribution box 80, the temperature control target space that can directly supply air through the duct is increased, and thus convenience is improved.
另外，多個第1管道連接孔91中的至少一個（一部分）第1管道連接孔91的開口面積與其他第1管道連接孔91的開口面積不同。藉此，於要求減小管道的佔有區域的情況下，藉由將細的管道連接於開口面積小的第1管道連接孔91，可應對抑制佔有面積的要求，於溫度控制對象空間所要求的要求風量大的情況下，藉由將粗的管道連接於開口面積大的第1管道連接孔91，可抑制由壓力損失所引起的送風機的不期望的輸出增加並且可將空氣供給至溫度控制對象空間。藉此，可根據狀況而進一步靈活地設定較佳的管道的配置型式，且可提高便利性。In addition, at least one (part of) the plurality of first pipe connection holes 91 has an opening area different from that of the other first pipe connection holes 91. Therefore, when it is required to reduce the occupied area of the pipe, by connecting a thin pipe to the first pipe connection hole 91 having a small opening area, it is possible to respond to the requirement for suppressing the occupied area and the space required for the temperature control target space. When a large air volume is required, by connecting a thick pipe to the first pipe connection hole 91 having a large opening area, it is possible to suppress an undesired increase in the output of the blower caused by a pressure loss, and to supply air to a temperature control target. space. Thereby, it is possible to further flexibly set a better pipe arrangement type according to the situation, and convenience can be improved.
另外，於分配箱80設置有多個第2管道連接孔92、93、94，藉此與所述同樣地可使可通過管道而直接供給空氣的溫度控制對象空間增加，因此可提高便利性。In addition, by providing a plurality of second duct connection holes 92, 93, and 94 in the distribution box 80, the temperature control target space that can directly supply air through the duct can be increased in the same manner as described above, thereby improving convenience.
另外，多個第2管道連接孔92、93、94中的至少一個（一部分）第2管道連接孔朝與其他第2管道連接孔不同的方向開口。藉此，例如於將所連接的管道延伸至溫度控制對象空間時，可根據溫度控制對象空間的位置，自彼此朝不同的方向開口的多個第2管道連接孔92、93、94中適宜選擇於所述情況下可極力抑制管道的長度的管道連接孔。藉此，可根據狀況而進一步靈活地設定較佳的管道的配置型式，且可提高便利性。In addition, at least one (part of) the plurality of second pipe connection holes 92, 93, and 94 (the second pipe connection hole) opens in a direction different from that of the other second pipe connection holes. Therefore, for example, when extending the connected pipe to the temperature control target space, it is possible to appropriately select a plurality of second pipe connection holes 92, 93, and 94 that are opened in different directions from each other according to the position of the temperature control target space. In this case, the pipe connection hole of the pipe length can be suppressed as much as possible. Thereby, it is possible to further flexibly set a better pipe arrangement type according to the situation, and convenience can be improved.
另外，朝不同的方向開口的例如第2管道連接孔92、93的開口面積彼此不同，藉此亦可選擇管道的連接的朝向，除此以外亦可選擇管道的直徑，因此可根據狀況而進一步靈活地設定較佳的管道的配置型式，且可提高便利性。另外，多個第2管道連接孔92、93、94包含朝相同方向開口的至少兩個第2管道連接孔。藉此，亦可增多用以連接管道的可選擇的管道連接孔，因此可根據狀況而進一步靈活地設定較佳的管道的配置型式，且可提高便利性。In addition, for example, the opening areas of the second pipe connection holes 92 and 93 that are opened in different directions are different from each other, so that the connection direction of the pipe can also be selected. In addition, the diameter of the pipe can also be selected. It is flexible to set a better pipeline configuration type, and can improve convenience. The plurality of second pipe connection holes 92, 93, and 94 include at least two second pipe connection holes that are opened in the same direction. In this way, the optional pipe connection holes for connecting the pipes can also be increased, so a better arrangement type of the pipes can be further flexibly set according to the situation, and convenience can be improved.
另外，多個第2管道連接孔92、93、94中的第2管道連接孔94於俯視時朝空氣取入口31側開口。然後，第2管道連接孔94與過濾器裝置313的下游側且空氣取入口31的上游側的部分藉由折回流路100而連接。根據該構成，可將第2管道連接孔92、93、94的一部分用作折回流路100的連接部，藉由將連接於朝空氣取入口31側開口的第2管道連接孔94的折回流路100延伸至空氣取入口側31，可使空氣返回而實現溫度控制的穩定性的提高。此時，可抑制折回流路100的長度，且可使空氣順暢地返回。In addition, the second duct connection hole 94 of the plurality of second duct connection holes 92, 93, and 94 opens toward the air intake port 31 side in a plan view. Then, the second duct connection hole 94 and a portion on the downstream side of the filter device 313 and on the upstream side of the air intake port 31 are connected by the return flow path 100. According to this configuration, a part of the second duct connection holes 92, 93, and 94 can be used as a connection portion of the reflow path 100, and the reflow can be connected to the second duct connection hole 94 opened to the air intake port 31 side. The path 100 extends to the air intake side 31, which allows the air to return and improve the stability of the temperature control. At this time, the length of the return flow path 100 can be suppressed, and air can be smoothly returned.
另外，於分配箱80設置有用以可拆裝地安裝封閉構件130的安裝結構AS，所述封閉構件130將第1管道連接孔91及第2管道連接孔92、93、94加以封閉。藉此，可防止空氣自不使用的第1管道連接孔91及第2管道連接孔92、93、94噴出並且可將空氣僅供給至溫度控制對象空間，從而可有效地將空氣供給至溫度控制對象空間。但是，安裝結構AS可選擇性安裝封閉構件130或管道，因此可抑制構成的複雜化並且可提高便利性。In addition, the distribution box 80 is provided with a mounting structure AS for detachably mounting a closing member 130 that closes the first pipe connection hole 91 and the second pipe connection holes 92, 93, and 94. Thereby, air can be prevented from being ejected from the unused first pipe connection holes 91 and the second pipe connection holes 92, 93, and 94, and air can be supplied only to the temperature control target space, so that air can be efficiently supplied to the temperature control. Object space. However, the mounting structure AS can selectively mount the closing member 130 or the pipe, so that the complexity of the structure can be suppressed and convenience can be improved.
此處，圖6是表示空氣調和裝置1的適用例的圖。於圖6中，空氣調和裝置1配置於配置溫度控制對象空間（具體而言為半導體製造設備S）的空間F2的下一級的空間F1。如圖6所示，於多個溫度控制對象空間位於空氣調和裝置1的上方的情況下，根據本實施形態的空氣調和裝置1，藉由將管道連接於朝上方開口的第1管道連接孔91，可設定極力抑制所連接的管道的彎曲部分而將管道延伸至所期望的溫度控制對象空間的管道配置型式。另外，藉由使用多個第1管道連接孔91，可抑制管道的增加並且可將經溫度控制的空氣供給至多個溫度控制對象空間。Here, FIG. 6 is a diagram showing an application example of the air-conditioning apparatus 1. In FIG. 6, the air-conditioning apparatus 1 is arranged in a space F1 next to the space F2 in which the temperature control target space (specifically, the semiconductor manufacturing equipment S) is arranged. As shown in FIG. 6, when a plurality of temperature control target spaces are located above the air conditioner 1, according to the air conditioner 1 of this embodiment, a pipe is connected to a first pipe connection hole 91 that opens upward. It is possible to set a pipe arrangement type that can suppress the bent part of the connected pipe as much as possible and extend the pipe to a desired temperature control target space. In addition, by using a plurality of first duct connection holes 91, an increase in ducts can be suppressed, and temperature-controlled air can be supplied to a plurality of temperature-control target spaces.
