Description

  The present invention is an air conditioner having a direct expansion coil composed of an outdoor unit and an indoor unit, and is a large special outdoor unit, or the performance of a vehicle air conditioner in which the outdoor unit and the indoor unit are integrated. The present invention relates to an air conditioner test system for performing a test.

  2. Description of the Related Art Conventionally, an air conditioner test system for performing a performance test in various temperature environments is known for an air conditioner that adjusts the temperature of a passenger compartment space or the like (for example, see Patent Document 1). As a known air conditioner test system, an air conditioner having a direct expansion coil as a specimen is divided into an outdoor unit and an indoor unit, so that the indoor side that houses the indoor unit and the room that houses the outdoor unit And a system-side air conditioner that adjusts the temperature inside the outdoor housing of the laboratory, and circulates air between the inside of the outdoor housing and the system-side air conditioner. The situation is reproduced.

Japanese Patent Publication No. 7-102425

  By the way, in the performance test of the test air conditioner, in the outdoor housing where the outside air side should be reproduced, it is a condenser or an evaporator of the outdoor unit as the test air conditioner starts and proceeds to steady operation. The temperature of the air after heat exchange discharged from the outdoor unit changes due to a change in the state temperature of the refrigerant flowing in the heat exchanger. Unless the heat capacity of the air in the outdoor housing and the side interior is greatly increased, the air temperature in the outdoor housing, which should reproduce the outside air side, changes due to the operation of the test air conditioner. This phenomenon cannot be suppressed even as a slightly larger outdoor housing as a buffer for suppressing changes in air temperature. Conversely, the air after heat exchange discharged from the outdoor unit that has changed in temperature has a large capacity and responsiveness. It is possible to reproduce the outside air state more accurately by immediately processing the temperature change with the coil (heat exchanger) of the good system side air conditioner and guiding it again into the outdoor housing.

  In addition, the air conditioner installed in the vehicle creates a comfortable temperature environment in the vehicle interior even in various weather conditions, so that the air that is the heat exchange air introduced into the outdoor unit can be used in the vehicle direction regardless of whether there is no wind or storm. Thus, even if the wind is in the direction of sucking out, the fan static pressure and the flow path adapted to it can be introduced to the condenser or evaporator of the outdoor unit with outside air at a flow velocity air in a predetermined range. Therefore, in the outdoor housing, the dynamic pressure of the blower fan of the system-side air conditioner is changed to a constant static pressure, and the wind speed and air in the outdoor unit are used only with the suction force of the outdoor fan of the test air conditioner. The system side air conditioner allows some dynamic pressure to remain. Therefore, the supply air blower outlet from the system side air conditioner can be arranged in the vicinity of the outside air inlet of the outdoor unit of the test air conditioner. For this reason, in order to maintain the temperature environment as the outside air in the periphery of the test air conditioner, the air outlet from which the temperature-controlled air is blown out by the system-side air conditioner is connected to the test air conditioner as much as possible. It is desirable to place them close. Similarly, in order to maintain the temperature environment as the outside air in the periphery of the test air conditioner, it is necessary to efficiently discharge the temperature-corresponding outside air corresponding to the heat exchanged by the outdoor unit of the test air conditioner to the outside of the housing. Also, it is desirable that the suction port for sucking the air whose temperature has been exchanged by the test air conditioner is located as close to the test air conditioner as possible.

  However, depending on the type of the test air conditioner, the position of the air inlet or outlet corresponding to the outside air may vary greatly due to the size of the sample air conditioner or the arrangement of components. In particular, in air conditioners such as large trucks and buses, air conditioners for railway vehicles, and the like, there are air conditioners integrated with indoor and outdoor units that are suitable for installation on the roof. This integrated air conditioner is also suitable, for example, for hanging under the floor between bogies of railway vehicles. In recent years, in order to promote high added value of vehicles, the arrangement of the components of the air conditioner is improved by improving the arrangement of the components of the air conditioner from the accommodation of the equipment of the vehicle. The number of in-vehicle air conditioners with greatly different arrangements of outlets and different external shapes is increasing. When such an air conditioner is used as a specimen, a performance test cannot be performed well with a test system for a separate unit of an indoor / outdoor unit of a domestic air conditioner type as in Patent Document 1.

  Concerning the setting of a blow-out port and suction port in accordance with the predetermined sample air conditioner of the previous example, there is a concern that another sample air conditioner may not match well or may be off-target. Is done. In particular, regarding a vehicle air conditioner that is provided in a vehicle such as a railway vehicle and in which an outdoor unit and an indoor unit are integrated, a difference in size, arrangement of components, and the like may be relatively large depending on the type. The above concerns become more prominent.

  On the other hand, it is conceivable to move the test air conditioner installed inside the housing in accordance with the position of the outlet. However, in such a method, it may be difficult to match the position of the test air conditioner to both the outlet and the suction port. For example, the test air conditioner is adjusted to the position of the outlet. When installed, there is a concern that the suction port will hardly function. Furthermore, the size of the housing is increased due to the fact that the housing is formed so as to allow the movement of such a large sample air conditioner in accordance with the largest sample air conditioner for which a performance test is expected. There is concern about inviting. Further, there is a concern that, due to the increase in the size of the housing, the internal space becomes wider, resulting in deterioration of energy efficiency related to temperature adjustment inside the housing.

  On the other hand, a specimen installation section that can install the test air conditioner inside the housing is provided, and for each performance test, construction of the wall of the housing in which a blowout port and a suction port are formed is performed. It is conceivable to change the positions of the air outlet and the air inlet in accordance with the test air conditioner installed in 1. However, in this case, workability in preparation for the performance test may be significantly reduced.

  In addition, for example, in advance, the size of the blowout opening is configured to be able to be changed by fitting a frame having a small opening into a large opening, and among the test air conditioners installed in the specimen installation unit, It is also conceivable to appropriately change the size so that such air can be sprayed at a place where it is desirable to spray air whose temperature is adjusted by the system-side air conditioner. However, in this case, the workability at the time of preparation for the performance test is improved as compared with the configuration in which the position of the air outlet is changed without changing the size of the air outlet, but the position of the air intake port of the test air conditioner is improved. It is necessary to prepare a frame for each model, and if the frame is limited, extra air will be blown out where it is not necessary to blow out temperature-controlled air by the system-side air conditioner. The Rukoto. For this reason, we are anxious about causing the deterioration of the energy efficiency etc. regarding a system side air conditioning apparatus.

  The present invention has been made to solve the above-described problems and the like, and an object thereof is to provide an air conditioner test system capable of improving work efficiency and energy efficiency.

  In the following, each means suitable for solving the above-described problems will be described in terms of items. In addition, the effect etc. peculiar to the means to respond | correspond as needed are added.

Means 1. In an air conditioner test system for performing a performance test of a vehicle air conditioner in which an outdoor unit and an indoor unit are integrated,
A housing;
A specimen installation portion provided inside the housing and capable of installing a vehicle air conditioner as a specimen;
Air conditioning means provided outside the housing for adjusting the temperature of the air;
Air supply guide means for guiding the air whose temperature has been adjusted by the air conditioning means to the vehicle air conditioner installed in the specimen installation section;
Exhaust guide means for guiding the air heat-exchanged by the outdoor unit-side heat exchanger as a result of the indoor unit-side temperature adjustment by the vehicle air conditioner installed in the specimen installation unit, to the outside of the housing,
The air supply guide means includes
An outer conduit connecting between the air conditioning means and an inlet opening formed in the wall of the housing;
One end is connected to the introduction opening, and the other end is provided with an inner conduit having an outlet from which air adjusted by the air conditioning means is blown out.
The exhaust guide means includes
One end portion side is connected to a lead-out opening formed in the wall portion of the housing, and on the other end portion side, the result of the indoor unit side temperature adjustment by the vehicle air conditioner installed in the specimen installation portion An exhaust pipe having a suction port for sucking the air heat-exchanged by the outdoor unit-side heat exchanger;
At least a part of the inner conduit and at least a part of the exhaust pipe are constituted by a flexible duct.

  According to the means 1, the position of the blowout port and the position of the suction port can be appropriately changed according to the size of the vehicle air conditioner used as the specimen and the arrangement of the constituent members. Therefore, regardless of the size of the vehicle air conditioner used as the specimen and the arrangement of components, the temperature of the vehicle air conditioner is adjusted by the air conditioning means on the system side with respect to the vehicle air conditioner. It is possible to efficiently blow out the air that has been heat-exchanged by the outdoor unit-side heat exchanger as a result of the indoor unit-side temperature adjustment by the vehicle air conditioner. As a result, the temperature environment of the peripheral part of the vehicle air conditioner can be efficiently maintained, and the energy efficiency related to the air conditioner can be improved.

  In addition, since it is not necessary to move the specimen installation portion inside the housing in order to align the vehicle air conditioner side, which is the specimen, with the position of the blowout port or the suction port, the increase in the size of the housing is suppressed. be able to. Accordingly, it is possible to suppress deterioration in energy efficiency and the like related to temperature adjustment inside the housing due to the wide internal space of the housing.

  Furthermore, when the performance test of the vehicle air conditioner is started, the inner duct and the exhaust pipe are simply moved by moving the air outlet and the suction port in accordance with the vehicle air conditioner installed in the specimen installation section. The air conditioner is suitably deformed and the air whose temperature is adjusted by the air conditioner is suitably blown to the vehicle air conditioner, and the outdoor unit side heat is the result of the indoor unit side temperature adjustment by the vehicle air conditioner. Air that has been heat-exchanged by the exchanger can be efficiently discharged. Therefore, for example, for each performance test of different types of vehicle air conditioners, the wall of the housing is changed in order to change the position of the air outlet and the suction port according to the vehicle air conditioner installed in the specimen installation unit. There is no need to do any construction work. Therefore, it is possible to improve workability when preparing for the performance test.

  In addition, for example, when the vehicle air conditioner as the specimen is changed, the vehicle is installed by changing the size of the outlet, or installed in the outlet and the inlet and the specimen installation part. It is possible to avoid a situation in which the distance to the air conditioning apparatus (target part) changes. For this reason, it is possible to reduce heat loss until the air whose temperature has been adjusted by the air conditioning means reaches the vehicle air conditioner, and to suppress a decrease in wind speed, etc., and to efficiently use the air whose temperature has been adjusted by the air conditioning means. Thus, it can be guided to the vehicle air conditioner. Therefore, the energy efficiency etc. regarding an air conditioning means can be aimed at. Furthermore, when the air whose temperature is adjusted by the air conditioning means efficiently reaches the vehicle air conditioning apparatus, it is possible to reduce the width of the air conditioning means such as air volume adjustment and temperature adjustment. Therefore, the adjustment workability of the air conditioning means can be improved, and a situation where a relatively high output air conditioning means becomes essential can be avoided. Moreover, the air conditioning apparatus for vehicles can efficiently guide the air heat-exchanged by the outdoor unit side heat exchanger as a result of the indoor unit side temperature adjustment to the outside of the housing. Accordingly, it is possible to suppress deterioration of energy efficiency related to temperature adjustment inside the housing.

  In addition, when the vehicle air conditioner is carried into and out of the housing, the inner conduit and the exhaust pipe are appropriately contracted to improve workability when the vehicle air conditioner is carried in and out. Can be achieved.

  The vehicle air conditioner includes the following: “a circulation pipe that circulates refrigerant, the indoor unit-side heat exchanger for exchanging heat between the refrigerant and indoor air, the refrigerant, and outdoor air. And an outdoor unit side heat exchanger for exchanging heat with each other and a compressor ”. The “exhaust pipe having a suction port for sucking in air that has been heat-exchanged in the outdoor unit-side heat exchanger as a result of temperature adjustment of the indoor unit by the vehicle air conditioner installed in the specimen installation unit” As a result of adjusting the temperature on the indoor unit side by the air conditioner, the air heat exchanged by the outdoor unit side heat exchanger may be actively sucked (using a fan, etc.) or installed in the specimen installation section. Heat is exchanged by the outdoor unit side heat exchanger as a result of temperature control of the indoor unit side of the vehicle air conditioner only by being arranged at a position where air is sent from the outdoor unit side heat exchanger of the vehicle air conditioner That does not spontaneously inhale the generated air (by the function of the fan of the outdoor unit side heat exchanger, etc., the air conditioner for the vehicle has adjusted the temperature on the indoor unit side as a result of heat exchange in the outdoor unit side heat exchanger) Air was introduced inside and introduced inside Or it may be what the gas is sent to the outlet opening side).

Mean 2. A slide wall provided to close a base opening formed in the wall of the housing and configured to be slidable along the wall of the housing;
2. The air conditioner test according to claim 1, wherein the slide wall portion includes an introduction-side slide member in which the introduction opening is formed, and a lead-out slide member in which the lead-out opening is formed. system.

  According to the means 2, the introduction opening and the lead-out opening are formed in the lead-in slide member and the lead-out slide member, so that the lead-in opening and the lead-out opening are formed on the wall of the housing. It is configured to be slidable along. For this reason, for example, when the position of the outlet is displaced (shifted) in the horizontal direction and the inner conduit is inclined and extended from the introduction opening, the introduction opening itself also follows. The sliding displacement will occur in the same direction. Thereby, the amount of deformation of the inner conduit when the position of the outlet is displaced in the horizontal direction can be reduced. For example, the angle of the inner conduit with respect to the wall portion provided with the introduction opening is too oblique. Due to this, it is possible to prevent a situation such as deterioration of the air flow in the inner conduit.

  Means 3. 3. The air conditioner test system according to claim 2, wherein at least a part of the outer conduit is constituted by a flexible duct, and the outer conduit is connected to the introduction-side slide member.

  For example, when the outer conduit is provided so as not to be displaced, in order to allow air from the outer conduit to flow into the inner conduit, an air supply chamber having an opening surrounding the sliding range (base opening) of the introduction-side slide member is connected to the relay member. As a side effect, the air from the air conditioning means is once introduced into the air supply chamber to convert the dynamic pressure of the outer conduit, which has a relatively high internal flow velocity, to static pressure in the air supply chamber. However, it is conceivable that the direction is changed while preventing the drift and flows into the inner conduit through the introduction opening. However, in this case, since the air supply chamber becomes relatively large, air leakage or pressure loss occurs in the air supply chamber, or the installation position of the introduction opening is biased, so that air in the air supply chamber There is a concern that the flow will deteriorate.

  In this respect, according to the means 3, the outer conduit is also configured to be deformable with the displacement of the introduction-side slide member. Therefore, even if the inlet opening and the outer conduit are not connected to a relatively large air supply chamber, the air from the outer conduit is converted to static pressure and the direction is changed while preventing drift, and the inner conduit is changed. It can flow. As a result, the air whose temperature has been adjusted by the air conditioning means can be more efficiently guided to the vehicle air conditioning apparatus, and energy efficiency related to the air conditioning means can be further improved.

Means 4. Of the inner conduit, a blowout port support portion that supports an end portion on the blowout port side,
Of the exhaust pipe, comprising a suction port support portion that supports an end portion on the suction port side,
The outlet support part and the suction port support part are:
With casters,
The air conditioner test system according to any one of means 1 to 3, further comprising a stopper capable of regulating the operation of the caster or displaceable to a position where the caster is separated from the floor surface.

  According to the means 4, it is possible to improve workability at the time of alignment of the blowout port and the suction port, and to prevent displacement of the blowout port and the suction port during the performance test.

  Means 5. The air conditioner test system according to any one of means 1 to 4, further comprising a drooping preventing means that supports the inner conduit and expands and contracts according to expansion and contraction of the inner conduit.

  According to the means 5, it is possible to prevent the inner conduit from sagging, to avoid the deterioration of the air flow in the inner conduit, and to make the inner conduit stretch and deform in a relatively smooth manner. it can.

  As shown in FIG. 4 and the like, the wall portion of the housing 2 where the introduction opening 11 is formed is formed with an introduction-side base opening 15 having a rectangular shape larger than the introduction opening 11. Furthermore, an introduction-side slide member 16 configured to be slidable along the wall portion of the housing 2 is provided so as to close a part of the introduction-side base opening 15. In the present embodiment, an introduction opening 11 is formed in the introduction side slide member 16.

  More specifically, as shown in FIG. 6, the introduction-side slide member 16 includes a base portion 18 having a plurality of casters 17 attached to the lower surface side, and a substantially rectangular frame portion that defines the introduction opening 11. 19, a support portion 20 that supports the frame portion 19 at a predetermined height above the base portion 18, and a guide member 21 that protrudes upward from the upper side portion of the frame portion 19.

A closing sheet 24 is attached. For convenience, illustration of the closing sheet 24 is omitted in FIG.

  A curtain rail 26 is provided on the upper edge of the introduction base opening 15 (the wall of the housing 2 that defines the wall) via a substantially U-shaped cap channel 25. It is attached so as to extend over the entire area. Further, as shown in FIG. 4, a pair of accordion curtains 27 are respectively attached to the curtain rails 26 on both sides of the introduction side slide member 16.

In addition, each accordion curtain 27 extends to the vicinity of the floor surface of the housing 2.

  When the introduction-side slide member 16 is slid, the accordion curtains 27 located on both sides of the introduction-side slide member 16 expand and contract in a follow-up manner. Thereby, no matter what position the introduction-side slide member 16 is slid, any gap is not generated in the introduction-side base opening 15. In this embodiment, the introduction side slide member 16 and the pair of accordion curtains 27 constitute a slide wall portion (on the introduction opening 11 side).

  As shown in FIG. 2, FIG. 5, FIG. 7, etc., the inner conduit 14 includes an introduction-side flexible duct 31 connected to the interior side surface of the frame portion 19 of the introduction-side slide member 16. The introduction-side flexible duct 31 includes a duct main body 32 having substantially the same shape and the same cross-sectional opening as the introduction opening 11, and duct angles 33 provided at both ends of the duct main body 32. In the present embodiment, the opening formed at the end of the introduction-side flexible duct 31 opposite to the end connected to the introduction-side slide member 16 constitutes the “blowout port 13”.

  Further, the inner conduit 14 includes a blower outlet box 35 as a blower outlet support part that supports an end part on the blower outlet 13 side of the introduction-side flexible duct 31. The air outlet box 35 includes a box body 36 having a substantially rectangular tube shape into which an end on the air outlet 13 side of the introduction side flexible duct 31 can be inserted, a ball caster 37 provided on the lower surface side of the box body 36, and a box body.

The height position of the air outlet 13 can be adjusted.

  Further, the introduction side flexible duct 31 and the outlet box 35 are connected to move the outlet box 35 in accordance with the sample air conditioner 3 (for example, the outdoor unit side heat exchanger or the compressor). Thus, the introduction-side flexible duct 31 is configured to expand and contract in a follow-up manner or to be deformed (the angle with respect to the introduction-side slide member 16 is changed). Furthermore, since the introduction-side flexible duct 31 and the introduction-side slide member 16 are connected, according to the displacement of the outlet box 35, when the introduction-side flexible duct 31 is deformed so as to extend obliquely, The introduction-side slide member 16 is configured to slide and follow.

  As shown in FIGS. 1 and 2, the exhaust guide pipe 7 is connected at one end to a lead-out opening 61 formed at the wall of the housing 2 and at the other end, the specimen installation portion 4. Is provided with an exhaust pipe 63 having a suction port 62 for sucking in air that has been heat-exchanged by the outdoor unit-side heat exchanger as a result of the indoor unit-side temperature adjustment.

  Further, the wall portion of the housing 2 where the lead-out opening 61 is formed (in this example, the wall portion opposite to the wall portion where the lead-in opening 11 is formed) has a larger lead-out side than the lead-out opening 61. A base opening 64 is formed. Further, a lead-out side slide member 65 configured to be slidable along the wall portion of the housing 2 and a pair of accordion curtains 66 (see FIG. 1) are provided so as to close the lead-out side base opening 64. ing. In the present embodiment, a lead-out opening 61 is formed in the lead-out side slide member 65. The lead-out side slide member 65 basically has the same configuration as the lead-in side slide member 16.

  Further, the exhaust pipe 63 basically has the same configuration as the inner conduit 14 of the air supply guide pipe 6. That is, the exhaust pipe 63 is connected to the inner surface side of the derivation side slide member 65, and of the derivation side flexible duct 67, the exhaust pipe 63 is opposite to the end connected to the derivation side slide member 65. And a suction port box 68 as a suction port support for supporting the end. In the present embodiment, the opening formed at the end of the outlet-side flexible duct 67 opposite to the end connected to the outlet-side slide member 65 constitutes the “suction port 62”.

  Further, the outlet side flexible duct 67 and the inlet box 68 are connected to each other so that the inlet box 68 is connected to the test air conditioner 3 (for example, an outdoor unit side fan installed near the outdoor unit side heat exchanger). And the outlet side flexible duct 67 expands and contracts in accordance with the discharge part of the upstream outdoor unit side fan and the part near the discharge side outdoor unit side heat exchanger of the upstream side fan. Or is deformed (the angle with respect to the derivation-side slide member 65 is changed). Furthermore, since the lead-out side flexible duct 67 and the lead-out side slide member 65 are connected, according to the displacement of the suction port box 68, when the lead-out side flexible duct 67 is deformed so as to extend obliquely, The lead-out side slide member 65 is configured to slide and follow. In addition, the exhaust pipe 63 is also provided with support rods and slide rails (not shown) that expand and contract (or appear and retract) and rotate according to the expansion and contraction and deformation of the outlet-side flexible duct 67. .

  In the present embodiment, a chamber (relay member) that is attached to the outdoor side surface of the introduction side slide member 16 is not provided on the outdoor side of the outlet side slide member 65. Instead, an exhaust box 69 having an opening surrounding the outlet-side base opening 64 is provided on the outer surface side of the wall portion of the housing 2 where the outlet-side base opening 64 is formed. The exhaust box 69 exchanges heat with the outdoor unit side heat exchanger as a result of temperature adjustment of the indoor unit side by the test air conditioner 3 discharged to the outside of the housing 2 through the exhaust pipe 63 and the outlet opening 61. In this embodiment, the exhaust port 70 of the exhaust box 69 is formed at a position higher than the outlet base opening 64.

  From the viewpoint of energy saving, the air (exhaust) discharged from the exhaust port 70 is discharged into a building that largely surrounds the housing 2, and a part of the temperature is adjusted by a building air conditioning return air facility (not shown). Part of the harmony device 5 may be sucked as return air.

  In addition, about the air suction inlet and the air outlet of the indoor unit side heat exchanger of the test air conditioner 3, a duct is connected according to the content of the test, and the air in the housing 2 and the indoor unit side heat exchanger are connected. The air that enters and exits the air can be shut off or mixed with the air in the housing 2 without a duct.

  As described in detail above, in the present embodiment, the position of the blowout port 13 and the position of the suction port 62 are appropriately set according to the size of the test air conditioner 3 that is a test body, the arrangement of the constituent members, and the like. Can be changed. Therefore, regardless of the size of the test air conditioner 3 used as the test object and the arrangement of the components, the temperature of the test air conditioner 3 is controlled by the system-side air conditioner 5 under a constant air temperature and humidity condition. The adjusted air can be suitably blown, and the air exchanged by the outdoor unit-side heat exchanger can be efficiently discharged as a result of the indoor unit-side temperature adjustment by the test air conditioner 3. As a result, the temperature environment of the periphery of the test air conditioner 3 can be efficiently maintained, and the energy efficiency related to the system-side air conditioner 5 can be improved.

  Further, since it is not necessary to move the specimen installation portion 4 inside the housing 2 in order to align the specimen air conditioner 3 side, which is the specimen, with the positions of the air outlet 13 and the suction inlet 62, the housing 2 Increase in size can be suppressed. Accordingly, it is possible to suppress deterioration in energy efficiency related to temperature adjustment inside the housing 2 due to the wide internal space of the housing 2.

  Furthermore, when the performance test of the test air conditioner 3 is started, the inner conduit is simply moved by moving the air outlet 13 and the suction port 62 in accordance with the test air conditioner 3 installed in the test object installation unit 4. 14 (introduction-side flexible duct 31) and the exhaust pipe 63 (outlet-side flexible duct 67) are deformed in a follow-up manner, and the air whose temperature is adjusted by the system-side air conditioner 5 with respect to the sample air conditioner 3 is changed. The air that has been suitably blown and the heat exchanged by the outdoor unit heat exchanger as a result of the indoor unit side temperature adjustment by the test air conditioner 3 can be efficiently discharged. For this reason, for example, for each performance test of the different types of test air conditioners 3, the positions of the air outlet 13 and the suction port 62 are changed according to the test air conditioner 3 installed in the specimen installation unit 4. Therefore, it is not necessary to perform the construction of the wall portion of the housing 2. Therefore, it is possible to improve workability when preparing for the performance test.

  Further, for example, when the test air conditioner 3 as a test specimen is changed, it can be dealt with by changing the size of the outlet 13, or the outlet 13 and the inlet 62 and the specimen installation unit 4. It is possible to avoid a situation in which the distance between the test air conditioner 3 (the target part thereof) installed in the terminal changes and the like. For this reason, it is possible to reduce the heat loss until the air whose temperature has been adjusted by the system-side air conditioner 5 reaches the sample air-conditioning apparatus 3, to suppress the decrease in the wind speed, and the like. The temperature-controlled air can be efficiently guided to the test air conditioner 3. Therefore, the energy efficiency etc. regarding the system side air conditioning apparatus 5 can be improved. Further, the air whose temperature has been adjusted by the system-side air conditioner 5 efficiently reaches the sample air-conditioning apparatus 3, so that the range of air volume adjustment, temperature adjustment, etc. of the system-side air conditioner 5 can be reduced. Therefore, the adjustment workability of the system-side air conditioner 5 can be improved, and a situation in which the relatively high-power system-side air conditioner 5 becomes essential can be avoided. Moreover, the air which was heat-exchanged with the outdoor unit side heat exchanger as a result of the indoor unit side temperature adjustment by the test air conditioner 3 can be efficiently guided outside the housing 2. Accordingly, it is possible to suppress deterioration in energy efficiency related to temperature adjustment inside the housing 2.

  In addition, when the sample air conditioner 3 is carried into and out of the housing 2, the inner conduit 14 and the exhaust pipe 63 are appropriately contracted, so that the sample air conditioner 3 is brought into and out of the housing 2. The workability can be improved.

  Further, in the present embodiment, the indoor unit is provided by the introduction opening 11 for introducing the air whose temperature is adjusted by the system-side air conditioner 5 into the housing 2, and the test air conditioner 3 and the test air conditioner 3. As a result of adjusting the side temperature, the lead-out opening 61 for discharging the air heat-exchanged by the outdoor unit-side heat exchanger to the outside of the housing 2 is slidably displaced along the wall portion of the housing 2; In addition, the lead-out side slide member 65 is formed. That is, the introduction opening 11 and the lead-out opening 61 are configured to be slidable along the wall portion of the housing 2. For this reason, for example, when the inner conduit 14 is inclined and extended from the introduction opening 11 by displacing the position of the outlet 13 in the horizontal direction (shifting), the introduction opening 11 itself. Will also follow and slide in the same direction. Thereby, the deformation amount of the inner conduit 14 when the position of the outlet 13 is displaced in the horizontal direction can be reduced. For example, the angle of the inner conduit 14 with respect to the wall portion provided with the introduction opening 11 is oblique. As a result, the air flow in the inner conduit 14 is deteriorated (the inner diameter of the inner conduit 14 is reduced, and the air supply guide pipe 6 is provided in the vicinity of the connection portion between the inner conduit 14 and the introduction opening 11). , Etc., can be prevented from being bent by a relatively large amount and the air flow is weakened.

  Further, for example, when the outer conduit 12 is provided so as not to be displaced, in order to allow air from the outer conduit 12 to flow into the inner conduit 14, an opening surrounding the sliding range (introduction-side base opening 15) of the introduction-side slide member 16. A relatively large air supply chamber having a portion is provided on the outer surface side of the wall portion of the housing 2 so as not to be displaceable, and air from the system-side air conditioner 5 is once allowed to flow into the air supply chamber so that the internal flow rate is increased. It is conceivable that the relatively fast dynamic pressure of the outer conduit 12 is converted into a static pressure in the air supply chamber, the direction is changed while preventing the drift, and the fluid flows into the inner conduit 14 through the introduction opening 11. However, in this case, since the air supply chamber becomes relatively large, air leakage or pressure loss occurs in the air supply chamber, or the installation position of the introduction opening 11 is biased. There is concern that the flow will worsen.

  In this regard, according to the present embodiment, a part of the outer conduit 12 is constituted by the heat-insulating flexible duct 52, and the outer conduit 12 (the air supply chamber 51 thereof) is connected to the introduction-side slide member 16. The outer conduit 12 is also configured to deform following the displacement of the introduction-side slide member 16. Therefore, even if there is no relatively large air supply chamber at the connection portion between the introduction opening 11 and the outer conduit 12, the air from the outer conduit 12 is converted to static pressure and the direction is changed while preventing drift. It can flow to the inner conduit 14. As a result, the air whose temperature is adjusted by the system-side air conditioner 5 can be guided to the test air conditioner 3 more efficiently, and energy efficiency related to the system-side air conditioner 5 can be further improved. it can.

  The air outlet includes an air outlet box 35 that supports an end of the inner conduit 14 on the outlet 13 side, and an air inlet box 68 that supports an end of the exhaust pipe 63 on the air inlet 62 side. The box 35 and the suction inlet box 68 include a ball caster 37 and a stopper 38 that can displace the ball caster to a position away from the floor surface. For this reason, while improving the workability | operativity at the time of position alignment of the blower outlet 13 and the suction inlet 62, position shift of the blower outlet 13 and the suction inlet 62 during a performance test can be prevented.

  Further, a support bar 41 and a slide rail 43 (hook 44) that support the inner conduit 14 (introduction-side flexible duct 31) and expand and contract in accordance with the expansion and contraction of the inner conduit 14 are provided. A support rod 41 and a slide rail 43 that support the exhaust pipe 63 (the lead-out side flexible duct 67) and expand and contract in accordance with the expansion and contraction of the exhaust pipe 63 are also provided corresponding to the exhaust pipe 63. For this reason, it is possible to prevent the inner conduit 14 and the exhaust pipe 63 from sagging, to avoid deterioration of the air flow in the inner conduit 14 and the exhaust pipe 63, and to expand and contract the inner conduit 14 and the exhaust pipe 63. The operation can be made relatively smooth.

  In addition, the introduction-side slide member 16 and the discharge-side slide member 65 are not suspended from the upper edges (wall portions of the housing 2) of the introduction-side base opening 15 and the discharge-side base opening 64, but are self-supporting. Is configured to do. Thereby, even if the introduction side slide member 16 and the lead-out side slide member 65 support a relatively heavy object, damage to the wall portion of the housing 2 can be suppressed.

There is no particular limitation on the configuration for preventing a gap from being formed in the portion. For example, a rectangular frame-like slide member that can slide and displace on the inner peripheral side of a substantially rectangular introduction-side base opening that is long on the left and right is provided, and the introduction-side base protrudes laterally from the left and right sides of the slide member. It is good also as providing the obstruction | occlusion plate which obstruct | occludes the site | part located in the side of a slide member among opening parts.

  (B) In addition, the structure for allowing the air outlet box 35 and the air inlet box 68 to move and keeping them stationary at predetermined positions is not particularly limited. For example, a caster having a roller The roller of the caster may be configured by a stopper that can regulate the rotation of the roller.

In this case, the exhaust box 69 may be connected to the derivation side slide member 65 and slidably displaced together with the derivation side slide member 65. Further, the exhaust box 69 can be omitted. A fan or the like for actively sucking air from the suction port 62 may be provided corresponding to the exhaust guide pipe 7.

  (E) In the above embodiment, the support bar 41 and the slide rail 43 are provided to prevent the inner conduit 14 (introduction-side flexible duct 31) and the exhaust pipe 63 (outlet-side flexible duct 67) from drooping.
