DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, modes for carrying out the present disclosure (hereinafter referred to as embodiments) will be described with reference to the drawings. In the following description of one embodiment, other embodiments applicable to the one embodiment will also be described as appropriate. The present disclosure is not limited to the one embodiment below, and different embodiments can be combined with each other or modified as desired without significantly impairing the effects of the present disclosure. Furthermore, the same components will be given the same reference numerals, and redundant descriptions will be omitted. Furthermore, components having the same functions will be given the same names. The contents shown are merely schematic, and for convenience of illustration, changes may be made from the actual configuration within the scope of not significantly impairing the effects of the present disclosure, and some components may be omitted or modified between drawings.

[0010] FIG. 1 is a schematic diagram of an air conditioning system 100 (replacement air conditioning system) according to a first embodiment that realizes the displacement air conditioning method of the present invention. The displacement air conditioning method of the present disclosure is a method for maintaining a predetermined environment in an air-conditioned area 10 formed below an air-conditioned space 11 from a floor surface 1a to a predetermined height. The "lower" here refers to the lower part of the air-conditioned space 11, which occupies the entire interior of the air-conditioned room 1. In the air conditioning system 100, the air-conditioned room 1 is a clean room, and an air conditioner 2 is provided above it. The air-conditioned space 11 is formed inside the air-conditioned room 1, and in the example shown, the air-conditioned space 11 is the interior space of the clean room. The air-conditioned area 10 is within the air-conditioned space 11 and is the lower region thereof. The air conditioner 2 is installed in the air-conditioned space 11. The air conditioner 2 supplies conditioned air Ac and is equipped with an air intake vent 25.

[0011] In the room 1 to be air-conditioned, there are devices 3 and workers 4 that are sources of heat load and dust generation.

[0012] Furthermore, in the air-conditioned room 1, separate from the operation of the air conditioner 2, the outdoor air conditioning unit 5 adjusts the amount of outside air required to maintain a positive pressure inside the room so that contaminated air from outside the air-conditioned room 1 does not flow into the air-conditioned room 1. The adjusted outside air is then supplied via duct 6a and first inlet 7, and excess air is exhausted outside the system of the air-conditioned room 1 through exhaust outlet 8 and duct 6b.

[0013] The dashed dotted line in Figure 1 is an imaginary line 9 that indicates the upper limit of the air-conditioned area 10 in the air-conditioned room 1 where temperature control and cleanliness control are required, and does not mean that there is a partition such as a ceiling. The area below the height of this line 9 is the air-conditioned area 10 of the air-conditioned room 1. The height of the air-conditioned area 10 is set to a height that exceeds the height of the equipment 3 and the height of the worker 4, and is generally about 2 m, but may be set to 3 m to 4 m depending on the height of the equipment 3.

[0014] The air conditioner 2 is configured with an intake port 21 that draws in air from the air-conditioned space 11, a cooling mechanism 22 that cools the air that has been drawn into the air-conditioned space 11, and an air supply port 25. The air supply port 25 supplies the conditioned air Ac that has been adjusted by the cooling mechanism 22 toward the bottom of the air conditioner 2. However, since the air-conditioned room 1 is a clean room in this embodiment, the contents of this embodiment will be described with a blower fan 23 and a high-performance dust filter 24 provided between the cooling mechanism 22 and the air supply port 25.

[0015] The air conditioner 2 draws in air from the room 1 to be air-conditioned by operating the blower fan 23, and cools the air as it passes through the cooling mechanism 22. Furthermore, the air conditioner 2 is equipped with a high-performance dust filter 24 (an example of a filter) that removes dust, and the high-performance dust filter 24 removes dust from the air. The air conditioner 2 is configured so that air that has passed through the high-performance dust filter 24 is supplied through the air intake port 25. In other words, the air conditioner 2 blows and supplies conditioned and dust-removed air (conditioned air Ac) downward through the air intake port 25 into the room 1 to be air-conditioned.

[0016] In this case, the distance L shown in FIG. 1 is the distance (height) from the floor surface 1a of the room 1 to be air-conditioned to the air supply port 25 of the air conditioner 2.

[0017] The conditioned air Ac blown downward from the air intake port 25 attracts and mixes with the surrounding air (ambient air Aa) as it moves downward. At this time, the downward wind speed decreases and the amount of air moving downward increases according to the amount of air being attracted and mixed. At the same time, the temperature of the air moving downward becomes higher than the temperature of the conditioned air Ac blown out from the air intake port 25 according to the amount of ambient air Aa being attracted and mixed. Through this series of operations, the temperature of the conditioned air Ac that reaches the air-conditioned area 10 becomes higher than the temperature of the conditioned air Ac when it is blown out from the air intake vent 25, thereby functioning to reduce the temperature difference between above and below the air-conditioned area 10. Furthermore, because the conditioned air Ac is supplied to the air-conditioned area 10 by the air conditioner 2, the dust count in the air-conditioned area 10 is kept below a certain value.

[0018] 2 to 5 are diagrams illustrating the flow of conditioned air Ac supplied from the air supply port 25 of the air conditioner 2. Generally, when the difference in wind speed (shear force) with the surrounding fluid is large, attraction and mixing are promoted, and the further downstream the flow develops, the greater the amount of entrained fluid and the slower the wind speed. In FIG. 2, the drawing shows the different attraction states when the wind speed is slow and the distance L is short; in FIG. 3, the wind speed is fast and the distance L is short; in FIG. 4, the wind speed is slow and the distance L is long; and in FIG. 5, the wind speed is fast and the distance L is long. The distance L is the same in FIGS. 2 and 3, and the distance L is the same in FIGS. 4 and 5.

[0019] On the other hand, the height of the air conditioner 2 and the air intake 25 of the air conditioner 2 is determined by various factors, such as the indoor height of the room 1 to be air-conditioned, the method of use, the layout of the devices and equipment, the construction of the air conditioning equipment, maintenance plans, costs, etc. For this reason, the distance L from the floor 1a of the room 1 to the air intake 25 of the air conditioner 2 generally differs for each plan (each building, each room).

[0020] This disclosure focuses on the fact that the state in which conditioned air Ac blown out from air intake port 25 attracts ambient air Aa before reaching air-conditioned area 10 is affected by the intake air speed and the distance L from floor surface 1a to air intake port 25, which forms the flow path for attracting ambient air. In other words, the displacement air conditioning method performed in air conditioning system 100 of the present disclosure supplies conditioned air Ac at a predetermined wind speed with a lower limit for the height of air intake port 25, which is determined by various factors.

[0021] That is, in the displacement air conditioning method of the present disclosure, when conditioned air Ac is supplied from air intake port 25 downward into air-conditioned space 11, the conditioned air Ac is supplied at a predetermined wind speed that corresponds to the distance L from floor surface 1a to air intake port 25. The predetermined wind speed here is the wind speed at which the conditioned air Ac supplied from air intake port 25 attracts the surrounding air, and is defined by a predetermined wind speed range that has a lower limit, with the lower limit value decreasing as the distance L becomes longer.

[0022] Specifically, when the position of the air intake port 25 is high and the distance L from the floor surface 1a is long (the flow path is long), the lower limit of the predetermined wind speed is set to be small, and when the distance L is short (the flow path is short), the lower limit of the predetermined wind speed is set to be large. This allows the conditioned air Ac blown out from the air intake port 25 at a low temperature to attract the ambient air Aa, so that the conditioned air Ac is supplied to the air-conditioned area 10 at a relatively elevated temperature.

[0023] FIG. 6 is a table illustrating the relationship between the distance L from the floor surface 1a of the air-conditioned room 1 to the air intake port 25 of the air conditioner 2 and the lower limit of the predetermined wind speed of the conditioned air Ac supplied through the air intake port 25 in this embodiment. The lower limit of the predetermined wind speed decreases as the distance L increases. In the illustrated example, if the distance L is 4 m or more, the predetermined wind speed is any wind speed of 0.5 m / s or more. If the distance L is 3 m or more but less than 4 m, the predetermined wind speed is preferably 1 m / s or more, and if the distance L is 2 m or more but less than 3 m, the predetermined wind speed is preferably 1.5 m / s or more. When changing the air volume of the conditioned air Ac blown out from the air intake port 25 in response to fluctuations in the thermal load, it is also preferable to change it so that it falls within these predetermined wind speed ranges.

[0024] These arbitrary wind speeds can be set appropriately depending on the design conditions of the air-conditioned room 1, but it is preferable to estimate the amount of ambient air Aa being drawn in, for example, using thermal fluid simulation, and set the wind speed from the air intake port 25.

[0025] 7 is a schematic diagram of an air conditioning system 100 of another embodiment. A first inlet 7 is arranged in the air-conditioned space 11. The first inlet 7 introduces outside air conditioned by an outdoor air-conditioning unit 5 into the air-conditioned space 11 via a duct 6a in order to maintain the air-conditioned room 1 at a positive pressure relative to the outside so that contaminated air outside the air-conditioned room 1 does not flow into the air-conditioned room 1.

[0026] It is preferable that the air conditioner 2 and the first air inlet 7 are arranged in the vicinity. Specifically, it is preferable that the first air inlet 7 and the suction port 21 of the air conditioner 2 are provided in the vicinity. Here, the vicinity means, for example, within 1 m. By installing the first air inlet 7 for introducing outside air and the suction port 21 in the vicinity, the outside air whose temperature, humidity, and cleanliness have been adjusted by the outdoor unit 5 is not substantially mixed with the air at the upper part of the air-conditioned room 1, and is quickly introduced from the suction port 21 into the air conditioner 2. As a result, the air-conditioned outside air can be efficiently utilized.

[0027] FIG. 8 is a schematic diagram of an air conditioning system 100 according to another embodiment. In the example shown in FIG. 8, the air conditioner 2 includes a second air inlet 7a for directly introducing the outside air air-conditioned by the outdoor unit 5 into the air conditioner 2 through the duct 6a.

[0028] In this way, by directly introducing the outside air air-conditioned by the outdoor unit 5 into the air conditioner 2 through the duct 6a and the second air inlet 7a, the outside air whose temperature, humidity, and cleanliness have been adjusted by the outdoor unit 5 is not mixed at all with the air at the upper part of the air-conditioned room 1, and the air-conditioned outside air can be efficiently utilized.

[0029] FIG. 9 is a schematic diagram of an air conditioning system 100 according to another embodiment. In the example shown in FIG. 9, the air conditioning system 100 includes dust removing devices 26a and 26b for sucking and removing dust in the air-conditioned space 11 inside the air-conditioned room 1, and the dust removing devices 26a and 26b are arranged in the air-conditioned space 11 (specifically, the air-conditioned area 10).

[0030] The reason for providing such dust removing devices 26a and 26b is that there is a large difference between the air volume (A) of the air conditioning air required for the heat treatment of the heat generating load source in the air-conditioned room 1 or the air-conditioned area 10 and the air volume (B) of the air conditioning air required based on the required cleanliness, and this is the case where A < B.

[0031] The dust removing devices 26a and 26b include a high-performance dust removing filter 24a having a dust removing function, a blower fan 23a, and a casing 27a.

[0032] Furthermore, if the heat treatment function and the dust removal function are separated, the air conditioner 2 does not need to be provided with the high-performance dust removal filter 24.

[0033] The installation positions and number of dust removal devices 26 are not limited to those shown in FIG. 9, and any number of devices may be installed in any orientation and position required.

[0034] 10 is a schematic diagram showing the configuration of an apparatus for performing temperature control of the air-conditioned area 10 by the air conditioner 2. The temperature control of the air-conditioned area 10 by the air conditioner 2 is performed by a valve 30 that adjusts the flow rate of chilled water CS supplied to the cooling mechanism 22, a temperature sensor 28 installed in the air-conditioned area 10, and a control device 29a that outputs an opening degree signal for the valve 30 based on the temperature of the air-conditioned area 10 measured by the temperature sensor 28. The temperature sensor 28, control device 29a, and valve 30 are connected by electrical signal lines shown by dashed lines. The valve 30 is provided in the air conditioner 2 as a temperature control mechanism for the air supplied through the air supply port 25.

[0035] When the cooling mechanism 22 is, for example, a heat exchanger that uses chilled water CS, the chilled water CS is supplied to the heat exchanger from a chiller or the like (not shown), and the opening of the valve 30 is increased or decreased in response to a signal from the control device 29a. Air introduced from the top of the air-conditioned room 1 is cooled as it passes through the heat exchanger, while the chilled water CS is heated and returned to the chiller or the like as return water CR.

[0036] Fig. 11 is a flowchart showing temperature control. Fig. 11 shows the displacement air conditioning method of the present disclosure, and is a flow for controlling the temperature of the supply air through air supply port 25 using valve 30 based on the temperature of air-conditioned area 10. Control device 29a determines whether temperature T of air-conditioned area 10 measured by temperature sensor 28 (step S11) is lower than the set temperature (step S12).

[0037] If the measured temperature T is lower than the set temperature (Yes), the opening of valve 30 is narrowed (reduced), thereby suppressing cooling by cooling mechanism 22 and increasing the supply air temperature (step S13). On the other hand, if the measured temperature T is higher than the set temperature in step S12 (No), control device 29a increases the opening of valve 30, thereby promoting cooling by cooling mechanism 22 and decreasing the supply air temperature (step S14). By performing this operation at regular time steps, the temperature of air-conditioned area 10 is controlled.

[0038] In step S12, the opening degree of the valve 30 may be maintained at the current state by setting a range such as the set temperature ±several degrees Celsius as the dead temperature zone.

[0039] 12 is a schematic diagram showing the configuration of an apparatus for controlling the cleanliness of the air-conditioned area 10 by the air conditioner 2. The cleanliness sensor 31 is a sensor that measures, for example, dust concentration, dust particle count, etc. The cleanliness control of the air-conditioned area 10 by the air conditioner 2 is performed by the cleanliness sensor 31, an air volume control mechanism 32, and a control device 29b. The cleanliness sensor 31 measures the cleanliness of the air-conditioned area 10. The air volume control mechanism 32 controls the volume of air supplied from the air inlet 25 by the blower fan 23, and is provided in the air conditioner 2. The control device 29b outputs a control signal to the air volume control mechanism 32 based on the dust concentration contained in the air in the air-conditioned area 10 measured by the cleanliness sensor 31.

[0040] The rotation speed of the blower fan 23 provided in the air conditioner 2 is controlled by an inverter serving as an air volume control mechanism 32. The cleanliness sensor 31, the control device 29b, and the air volume control mechanism 32 are connected by electric signal lines shown by dashed lines.

[0041] The control device 29b controls the supply air volume from the air inlet 25 using the air volume control mechanism 32 based on the cleanliness of the air-conditioned area 10. Note that the air volume control mechanism 32 may be a damper with an adjustable opening instead of an inverter, and the supply air volume can be controlled, for example, by rotating the blower fan 23 at a constant speed and adjusting the opening of the damper.

[0042] Fig. 13 is a flowchart showing cleanliness control. Fig. 13 shows the displacement air conditioning method of the present disclosure, and is a flow for controlling the supply air volume of air inlet 25 by air volume control mechanism 32 based on the cleanliness of air-conditioned area 10. Control device 29b determines whether dust concentration C related to the cleanliness of air-conditioned area 10 measured by cleanliness sensor 31 (step S21) is higher than the dust concentration related to the specified cleanliness (step S22).

[0043] If the measured dust concentration C is higher than the dust concentration associated with the specified cleanliness level (Yes), control device 29b controls air volume control mechanism 32 to increase the rotation speed of blower fan 23 and increase the supply air volume (step S23). On the other hand, if in step S22 the dust particle count C associated with the measured cleanliness level is lower than the dust particle count associated with the specified cleanliness level (No), control device 29b controls air volume control mechanism 32 to decrease the rotation speed of blower fan 23 and decrease the supply air volume (step S24). By performing this operation at regular time steps, the cleanliness of air-conditioned area 10 is controlled.

[0044] In step S22, the air volume control mechanism 32 may maintain the current rotational speed of the blower fan 23 by setting a range such as the set dust concentration ± the dead-band dust concentration as the dead-band dust concentration.

[0045] When the temperature control and the cleanliness (dust count) control of the air-conditioned area 10 are performed simultaneously, the two controls are executed in parallel.

[0046] Although not shown, the control devices 29a and 29b are configured to include, for example, a CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory), etc. The control devices 29a and 29b are realized by a predetermined program (control program) stored in the ROM being loaded into the RAM and executed by the CPU. The program here is for causing a computer to execute the air conditioning system 100.

[0047] In the illustrated examples shown so far, the space 11 to be air-conditioned is the interior space of a clean room, but it may also be applied to various spaces such as a factory, a hall, or a room for other purposes.

[0048] According to the displacement air conditioning method of the present disclosure, it is possible to set the supply air velocity that creates a favorable induction state according to the height of the air supply port 25 of the air conditioner 2, which is determined by various factors, and to prevent low-temperature conditioned air Ac, which would be a factor in impairing the comfort of the workers 4, from being supplied to the air-conditioned area 10. This reduces the temperature difference between the top and bottom, improving the comfort of the workers 4 and providing an environment with a stable temperature, etc. for the equipment 3.

[0049] By supplying conditioned air Ac to the air-conditioned area 10 located below the air-conditioned room 1 that forms the air-conditioned space 11 where displacement air-conditioning is performed, air conditioning can be performed efficiently with a small amount of air compared to a method that mixes and air-conditions the entire air-conditioned room 1, which also contributes to energy savings. Furthermore, since the indoor air is circulated through the air conditioning unit 2 placed in the air-conditioned room 1, there is no need to transport the indoor air through a duct to the outside of the air-conditioned room 1 and return it to the outdoor air-conditioning unit 5, etc. This also makes it possible to reduce the energy required to transport the air.

[0050] Furthermore, the air conditioning device 2 can be installed at a position higher than the area 10 to be air-conditioned, improving the footprint within the room 1 to be air-conditioned and increasing the degree of freedom in installing the devices 3. At the same time, it becomes easier to accommodate changes in the layout of the room 1 to be air-conditioned. [Explanation of symbols]
