Description

[Technical Field]

[0001] The present invention relates to an air conditioning system installed in a room of a building. [Background technology]

[0002] Conventionally, an air conditioning system installed in a room of a building is known in which an air conditioner blows temperature-adjusted air downward from an outlet installed in the ceiling of the room, thereby adjusting the temperature of a desired area directly below the outlet in the room.

[0003] For example, Patent Document 1 describes an air conditioning system installed in a hospital operating room, which has a downward-facing outlet in the ceiling directly above an operating table located approximately in the center of the operating room, and is configured to blow air cooled by an air conditioner downward from the outlet, thereby adjusting the operating table or surgical field area directly below the outlet to a desired temperature. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6481283 Summary of the Invention [Problem to be solved by the invention]

[0005] Air conditioning systems such as those described above typically have an operation panel installed on the wall of the room, and are configured to control the operation of the air conditioner based on the air temperature in the room detected by a temperature sensor and the set temperature set on the operation panel.

[0006] However, in conventional air conditioning systems, the temperature sensor that detects the air temperature inside the room is installed on the wall of the room, for example, built into the operation panel, so the area closer to the outer wall than the area directly below the air outlet is adjusted to the desired temperature, which makes it difficult to adjust the temperature, as the temperature in the area directly below the air outlet becomes too low compared to the desired temperature.

[0007] The present invention aims to solve these problems, and its purpose is to provide an air conditioning system that can adjust the temperature of both the desired area of ​​a room and the surrounding area to a comfortable temperature. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, an air conditioning system according to an embodiment of the present invention will be described in detail with reference to the drawings.

[0015] As shown in FIGS. 1 and 2, an air conditioning system 1 according to a first embodiment of the present invention is installed in an operating room 3, which is a room in a hospital 2, which is a building.

[0016] The operating room 3 is a space partitioned by a floor 3a, four walls 3b, and a ceiling 3c, and an operating table 4 is installed approximately in the center of the floor 3a. In addition, a plurality of surgical equipment 5, such as a suction machine, an anesthesia machine, an electric scalpel, an ultrasonic scalpel, a ventilator, and a monitor, are arranged around the operating table 4 on the floor 3a of the operating room 3. Although not shown in detail, a shadowless lamp that projects light toward the operating table 4 is suspended by an arm 6 from the ceiling 3c of the operating room 3.

[0017] The air conditioning system 1 has a downward air outlet 10 provided on the ceiling 3c of the operating room 3. The downward air outlet 10 has a rectangular shape in a plan view and is located approximately in the center of the ceiling 3c, i.e., directly above the operating table 4, so that it blows air directly downward toward the operating table 4.

[0018] As shown in Fig. 3, each downward air outlet 10 can be configured to include a rectangular box 11. In this embodiment, the downward air outlet 10 is configured such that two boxes 11 are connected to each other in the horizontal direction, and air is blown downward from downward-facing lattice-like louvers 12 arranged at the bottom end openings of each box 11. Note that the downward air outlet 10 can also be configured such that pairs of two boxes 11 are arranged in multiple rows in a direction perpendicular to the plane of the paper in Fig. 3.

[0019] The downward air outlet 10 may be configured to have a HEPA (High Efficiency Particulate Air) filter 13 attached thereto. In this embodiment, a HEPA filter 13 is attached inside each box 11. With this configuration, the air blown out from the downward air outlet 10 toward the inside of the operating room 3 can be purified by the HEPA filter 13.

[0020] 1 and 2, the air conditioning system 1 includes a downward air conditioning unit 20. In this embodiment, the downward air conditioning unit 20 is disposed inside a wall portion 3b at a corner of a substantially rectangular floor 3a. The downward air conditioning unit 20 is a so-called air conditioner, and can supply temperature-adjusted air to the downward air outlets 10.

[0021] In this embodiment, an inlet 21 is provided in the portion of the wall 3b where the downward air-conditioning unit 20 is disposed, and the downward air-conditioning unit 20 can draw air from inside the operating room 3 through the inlet 21. An electric heater 22 and a cooling coil 23 are provided inside the downward air-conditioning unit 20, and the air drawn in through the inlet 21 is heated or cooled by the electric heater 22 or the cooling coil 23 to adjust its temperature. The downward air-conditioning unit 20 is equipped with a blower fan 24 and is connected to the downward outlet 10 by a duct 25, and the temperature-adjusted air is supplied to the downward outlet 10 through the duct 25 by the blower fan 24. When the temperature-adjusted air is supplied from the downward air-conditioning unit 20 to the downward outlet 10, the air is blown downward from the downward outlet 10 towards the operating table 4.

[0022] The air conditioning system 1 can also be configured such that, in addition to the downward air outlets 10, peripheral air outlets 30 are provided on the ceiling 3c of the operating room 3. In this embodiment, four peripheral air outlets 30, each having a rectangular shape in a plan view, are provided in the portion of the ceiling 3c between the downward air outlets 10 and the four wall portions 3b. That is, the four peripheral air outlets 30 are provided on the ceiling 3c, centered around the downward air outlet 10, and are arranged at intervals in the front, back, left, and right directions relative to the downward air outlet 10.

[0023] 3, each peripheral air outlet 30 can be configured to include a rectangular box 31, similar to the downward air outlet 10. In this embodiment, each peripheral air outlet 30 is configured with one box 31. A cover 32 is attached to the lower end opening of the box 31, and this cover 32 directs the air outlet 30's airflow direction toward an area outside the downward air outlet 10.

[0024] 4, the cover 32 is shaped like a rectangular dish and has four side walls and a bottom wall, with downward lattice-shaped downward openings 32a provided in the bottom wall, a horizontally oriented first horizontal opening 32b provided in the side wall facing away from the downward outlet 10, and horizontally oriented second horizontal openings 32c provided in the side walls on both sides connected to the side wall with the first horizontal opening 32b. In this way, the peripheral outlet 30 is configured to blow air downward and in three horizontal directions facing outward from the downward outlet 10.

[0025] The peripheral air outlets 30 can also be configured to have HEPA filters 33 attached thereto, similar to the downward air outlets 10. In this embodiment, a HEPA filter 33 is attached inside each box 31. With this configuration, the air blown out from each peripheral air outlet 30 toward the inside of the operating room 3 can be purified by the HEPA filter 33.

[0026] 1 and 2, the air conditioning system 1 includes a periphery air conditioning unit 40. In this embodiment, the periphery air conditioning unit 40 is disposed inside the wall 3b at a corner of the substantially rectangular floor 3a that is diagonally opposite to the downward air conditioning unit 20. The periphery air conditioning unit 40 is a so-called air conditioner, similar to the downward air conditioning unit 20, and can supply temperature-adjusted air to the periphery outlet 30.

[0027] In this embodiment, an intake port 41 is provided in the portion of the wall 3b where the periphery air-conditioning unit 40 is disposed, and the periphery air-conditioning unit 40 can draw in air from inside the operating room 3 through the intake port 41. An electric heater 42 and a cooling coil 43 are provided inside the periphery air-conditioning unit 40, and the air drawn in through the intake port 41 is heated or cooled by the electric heater 42 or the cooling coil 43 to adjust its temperature. The periphery air-conditioning unit 40 is equipped with a blower fan 44 and is connected to the periphery outlet 30 through a duct 45, and the temperature-adjusted air is supplied to the periphery outlet 30 through the duct 45 by the blower fan 44. When the temperature-adjusted air is supplied from the periphery air-conditioning unit 40 to the periphery outlet 30, the air is blown out from the periphery outlet 30 downward and in three horizontal directions facing the outer area relative to the downward-directed outlet 10.

[0028] An operation panel 50 is installed on the wall 3b. The operation panel 50 is configured such that a group of operation switches for operating the downward air-conditioning unit 20 and a group of operation switches for operating the peripheral air-conditioning unit 40 are provided separately. By operating the operation switch for the downward air-conditioning unit 20 on the operation panel 50, it is possible to perform operations such as turning the downward air-conditioning unit 20 on and off, changing the set temperature for the downward air-conditioning unit 20, and changing the operation mode of the downward air-conditioning unit 20. Furthermore, by operating the operation switch for the peripheral air-conditioning unit 40 on the operation panel 50, it is possible to perform operations such as turning the peripheral air-conditioning unit 40 on and off, and changing the set temperature for the peripheral air-conditioning unit 40. The operation panel 50 is not limited to being installed on the wall 3b, and may be in the form of a remote controller.

[0029] The air conditioning system 1 is equipped with a wall temperature sensor 60 installed on the wall 3b of the operating room 3. The wall temperature sensor 60 can detect the temperature of the air near the wall 3b inside the operating room 3. In this embodiment, the wall temperature sensor 60 is built into the operation panel 50. The wall temperature sensor 60 may also be installed on the wall 3b separately from the operation panel 50. The wall temperature sensor 60 can be of various configurations or types as long as it can measure the air temperature.

[0030] The air conditioning system 1 also includes an outlet-side temperature sensor 70 installed at the downward outlet 10. The outlet-side temperature sensor 70 can detect the temperature of the air itself blown out from the downward outlet 10. The outlet-side temperature sensor 70 may be installed at the bottom opening of the downward outlet 10, or may be located directly above the bottom opening of the downward outlet 10. In this embodiment, the outlet-side temperature sensor 70 is fixed to the outward-facing side wall of one of the boxes 11, and detects the temperature of the air inside the box 11 at the downward outlet 10. The outlet-side temperature sensor 70 can be of various configurations or types as long as it can measure the temperature of the air.

[0031] The downward air conditioning unit 20 is equipped with a control unit 26 that is configured, for example, by a microcomputer equipped with a CPU. The control unit 26 is connected to an operation panel 50, a wall-side temperature sensor 60, and an outlet-side temperature sensor 70, and controls the operation of the downward air conditioning unit 20 based on inputs from the operation switch for the downward air conditioning unit 20 on the operation panel 50, the wall-side temperature sensor 60, and the outlet-side temperature sensor 70, etc.

[0032] The operation panel 50 functions as a switching operation unit that can switch the operation mode of the downward air conditioning unit 20 between a first mode in which temperature adjustment is performed based on the temperature detected by the wall-side temperature sensor 60 and the set temperature, and a second mode in which temperature adjustment is performed based on the temperature detected by the outlet-side temperature sensor 70 and the set temperature. For example, the operation panel 50 is configured to include a mode selection switch as an operation switch for the downward air conditioning unit 20. When the mode selection switch on the operation panel 50 is operated to select the first mode, the operation of the downward air conditioning unit 20 is controlled by the control unit 26 so that the temperature detected by the wall-side temperature sensor 60 approaches the set temperature set by the operation switch for the downward air conditioning unit 20 on the operation panel 50. Furthermore, when the mode selector switch on the operation panel 50 is operated to select the second mode, the operation of the downward air conditioning unit 20 is controlled by the control unit 26 so that the temperature detected by the outlet-side temperature sensor 70 approaches the set temperature set by the operation switch for the downward air conditioning unit 20 on the operation panel 50.

[0033] The ambient air conditioning unit 40 includes a control unit 46, which is configured by, for example, a microcomputer with a CPU. The control unit 46 is connected to the operation panel 50 and the wall temperature sensor 60, and controls the operation of the ambient air conditioning unit 40 based on inputs from the operation switch for the ambient air conditioning unit 40 on the operation panel 50 and the wall temperature sensor 60. More specifically, the operation of the ambient air conditioning unit 40 is controlled by the control unit 46 so that the temperature detected by the wall temperature sensor 60 approaches the set temperature set by the operation switch for the ambient air conditioning unit 40 on the operation panel 50. In other words, the set temperature for the ambient air conditioning unit 40 can be set separately from the set temperature for the downward air conditioning unit 20, and the ambient air conditioning unit 40 can operate to adjust the temperature inside the operating room 3 in a system separate from the downward air conditioning unit 20.

[0034] As described above, in the air conditioning system 1 of this embodiment, by operating the mode selector switch for the downward air conditioning unit 20 on the operation panel 50, the operating mode of the downward air conditioning unit 20 can be switched between a first mode in which temperature adjustment is performed based on the temperature detected by the wall-side temperature sensor 60 and the set temperature set by the operation switch for the downward air conditioning unit 20 on the operation panel 50, and a second mode in which temperature adjustment is performed based on the temperature detected by the outlet-side temperature sensor 70 and the set temperature set by the operation switch for the downward air conditioning unit 20 on the operation panel 50.

[0035] Therefore, according to the air conditioning system 1 of this embodiment having the above configuration, by setting the operation mode of the downward air conditioning unit 20 to the second mode, the temperature of the air blown out from the downward air outlet 10 can be adjusted to the set temperature set on the operation panel 50. This makes it easy to adjust the temperature of the operating table 4 or the surgical field area directly below the downward air outlet 10 to the desired temperature.

[0036] On the other hand, according to the air conditioning system 1 of this embodiment having the above-mentioned configuration, by setting the operating mode of the downward air conditioning unit 20 to the first mode, the temperature of the air in the area outside the periphery of the operating table 4 in the operating room 3, that is, the area that tends to become hot due to the placement of multiple heat-generating surgical equipment 5 such as a suction machine, anesthesia machine, electric scalpel, ultrasonic scalpel, ventilator, monitor, etc., can be easily adjusted to the set temperature set on the operation panel 50 by the air blown out from the downward outlet 10.

[0037] As described above, the air conditioning system 1 of this embodiment having the above configuration can separately adjust the temperature of the operating table 4 or surgical field area and the surrounding area inside the operating room 3. Therefore, when performing surgery in the operating room 3, it is possible to easily adjust the temperature of the air around the operating table 4 or surgical field area to a temperature that will not cause hypothermia in the patient on the operating table 4 and is comfortable for the doctor performing the surgery, while also adjusting the temperature of the air in the area around the operating table 4 to a comfortable temperature for other people, such as assistants supporting the surgery.

[0038] In addition, in this embodiment, the air conditioning system 1 is provided with a peripheral air outlet 30 on the ceiling 3c of the operating room 3, separate from the downward air outlet 10, and a peripheral air conditioning unit 40 that supplies temperature-adjusted air to the peripheral air outlet 30.The peripheral air conditioning unit 40 adjusts the temperature based on the temperature detected by the wall temperature sensor 60 and the set temperature set by the switch for the peripheral air conditioning unit 40 on the operation panel 50.Therefore, the temperature of the air around the operating table 4 can be more easily adjusted to a comfortable temperature for other people, such as assistants assisting the surgery, by the peripheral air conditioning unit 40, which is on a system separate from the downward air conditioning unit 20 that blows air from the downward air outlet 10 directed toward the operating table 4 or the surgical field area, based on the temperature detected by the wall temperature sensor 60 and the set temperature set by the switch for the peripheral air conditioning unit 40 on the operation panel 50.

[0039] In particular, in this embodiment, a plurality of peripheral air outlets 30 are provided on the ceiling 3c, centered around the downward air outlet 10, and arranged at intervals in all directions relative to the downward air outlet 10, and the air outlets 30 are each configured to blow air toward an outer area relative to the downward air outlet 10. This allows the air blown out from the peripheral air outlets 30 to flow downward and along the ceiling 3c toward the wall 3b, making it less likely to mix with the air blown out from the downward air outlets 10. This makes it possible to more efficiently adjust the temperature of the air around the operating table 4 in the operating room 3 to a temperature that is comfortable for other people, such as assistants supporting the surgery.

[0040] As shown in Figures 5 and 6 as a second embodiment, the air conditioning system 1 of the present invention can also be configured without the peripheral area outlet 30 and the peripheral area air conditioning unit 40. In this second embodiment shown in Figures 5 and 6, downward air conditioning units 20 are respectively arranged inside wall portions 3b at both diagonal corners of the floor 3a of the operating room 3, and these two downward air conditioning units 20 are connected to the downward air outlet 10 by ducts 25.

[0041] 7, the downward air outlet 10 is configured with four boxes 11 arranged horizontally, and each box 11 is fitted with a HEPA filter 13. An air outlet-side temperature sensor 70 is fixed to the outward-facing side wall of each of the two boxes 11 at both ends, and the temperature of the air inside these two boxes 11 of the downward air outlet 10 is detected by the air outlet-side temperature sensors 70 and sent to the control unit 26.

[0042] In the air conditioning system 1 of the second embodiment having such a configuration, by operating the mode changeover switch for the downward air conditioning unit 20 on the operation panel 50, the operating mode of the downward air conditioning unit 20 can be switched between a first mode in which temperature adjustment is performed based on the temperature detected by the wall-side temperature sensor 60 and the set temperature set by the operation switch for the downward air conditioning unit 20 on the operation panel 50, and a second mode in which temperature adjustment is performed based on the temperature detected by the outlet-side temperature sensor 70 and the set temperature set by the operation switch for the downward air conditioning unit 20 on the operation panel 50.

[0043] Therefore, with the air conditioning system 1 of the second embodiment, by setting the operating mode of the downward air conditioning unit 20 to the second mode, the temperature of the air blown out from the downward outlet 10 can be adjusted to the set temperature set on the operation panel 50, thereby making it easy to adjust the temperature of the operating table 4 or surgical field area directly below the downward outlet 10 to the desired temperature.

[0044] In addition, when it is desired to adjust the temperature of the air in the area outside the operating table 4 in the operating room 3, the operating mode of the downward air conditioning unit 20 can be set to the first mode, and the air blown out from the downward outlet 10 can easily adjust the temperature of the air in the area outside the operating table 4 in the operating room 3 to the set temperature set on the operation panel 50.

[0045] The present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the spirit and scope of the present invention.

[0046] For example, in the above embodiment, the air conditioning system 1 is installed in the operating room 3 of the hospital 2, but the air conditioning system 1 can also be installed in a room in a building other than the operating room 3 of the hospital 2, as long as the room has a requirement to adjust the air temperature in two areas separately.

[0047] In the above embodiment, the downward air outlet 10 is provided in approximately the center of the ceiling 3c, but the position of the downward air outlet 10 on the ceiling 3c can be changed in various ways. In addition, the number of downward air outlets 10 can also be changed in various ways.

[0048] In the above embodiment, four peripheral air outlets 30 are arranged at intervals in front, behind, to the left and right of the downward air outlet 10, but the number and arrangement of the peripheral air outlets 30 can be changed in various ways. [Explanation of symbols]
