Description

Technical Field

[0001] The present invention relates to a temperature and humidity control system and a temperature and humidity control device for an elevator. Background Art

[0002] In Patent Document 1, there is described an air conditioning system for cooling and heating the inside of an elevator car. The air conditioning system has an air conditioning device provided in a place outside the elevator car. In this air conditioning system, when the car reaches a predetermined intake and exhaust position, a car-side duct provided in the car and a car-outside duct provided in the hoistway from the air conditioning device are connected, whereby the air of the air conditioning device is conveyed into the car and the temperature inside the car is adjusted.

[0003] Patent Document 1: Japanese Unexamined Patent Application Publication No. 2007-84193

[0004] In the air conditioning system of Patent Document 1, it is configured that each time the car moves to the intake and exhaust position, the connecting portion of the car-outside duct pushes open the end portion of the car-side duct, whereby the two ducts are connected. Therefore, in the air conditioning system of Patent Document 1, there is a concern about a reduction in strength such as wear of the duct connecting mechanism. In addition, the duct connecting mechanism of the air conditioning system of Patent Document 1 is sensitive to position deviation. For example, when the alignment of the connecting portion between the elevator car and the car-outside duct is not engaged due to position deviation during design and installation at the construction site, it is necessary to redesign and reinstall again. Further, in the case of position deviation caused by an earthquake or the like, the positions of the connecting portion and the end valve are not aligned, and the car-outside duct and the car-side duct may not be connected. In addition, due to the position deviation of the ducts, the connecting portion and the end valve may collide with other parts or each other, which may cause deformation of the end valve or the connecting portion or the car may not be able to stop. In this case, not only the intended air conditioning cannot be performed, but also the elevator passengers may be trapped and the maintenance staff must go to manually rescue them. Moreover, the maintenance and restoration of the air conditioning system take time. Summary of the Invention

Detailed Embodiment

[0033] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, in each figure, the same or corresponding parts are denoted by the same reference numerals, and the description thereof is simplified or omitted.

[0034] Embodiment 1

[0035] Figure 1 is a schematic view showing the temperature and humidity control system according to the present embodiment and its vicinity. Figure 1 is a cross-sectional view of the vicinity of the hoistway of the elevator and the landing of the elevator provided in the building as viewed from the front. Figure 2 is a schematic view showing the fan disposed at the exhaust port, and is a front view when the fan is viewed from the upper side of the Figure 1 paper surface.

[0036] The temperature and humidity control system of the present embodiment includes a duct 11 provided in a building 10, a fan 12 provided in the duct 11, and a hoistway opening / closing part 22 formed in a hoistway 21 of an elevator 20.

[0037] As Figure 1 shown, the building 10 has a plurality of floors 10A including underground floors and above-ground floors. In Figure 1 , the underground floor of the first basement level and the above-ground floors of the first and second above-ground levels are illustrated, however, the number of floors of the building 10 is not limited. Each floor 10A is demarcated by a floor 10C and a ceiling 10D. Additionally, for ease of explanation, the space between the ceiling 10D of each floor and the floor 10C directly above it is also referred to as a ceiling space 10E.

[0038] One end of the duct 11 is connected to an exhaust port 13 formed in the ceiling 10D of the underground floor. As Figure 1 and Figure 2 shown, a fan 12 is provided at the exhaust port 13. The fan 12 sucks in the air in the underground floor room from the exhaust port 13 and guides it into the duct 11. In Figure 2 , the front shape of the exhaust port 13 is shown as a circle, however, the shape of the exhaust port 13 and the cross-sectional shape of the duct 11 connected thereto are not limited, and for example, it may also be a quadrilateral. In addition, the shape of the fan 12 is not limited to the Figure 2 shown shape. As Figure 1 shown, an exhaust mask 14 is disposed at the exhaust port 13.

[0039] In Figure 1 's example, the duct 11 is formed to penetrate at least from the underground floor to the ceiling 10D of the second floor. However, the duct 11 may, for example, be provided only in the ceiling space 10E of the underground floor, and in the case where the building 10 has a plurality of floors 10A, it may also be configured to penetrate a part or all of the plurality of floors 10A.

[0040] The elevator 20 has a hoistway 21 that penetrates each floor 10A of the building 10. A car 23 of the elevator 20 is disposed in the hoistway 21 so as to be movable in the vertical direction. An opening for ventilation of the air inside the car 23 is formed in the car 23. A car fan may also be provided at the opening. A landing 24 is provided on each floor 10A of the building 10. The landing 24 is a space adjacent to the hoistway 21. A landing door 25 is provided at the landing 24 on each floor 10A.

[0041] In the side wall of the hoistway 21 where the landing door 25 is formed, a plurality of openings are formed, and a hoistway opening / closing part 22 is formed in each opening. The plurality of openings are formed near the ceiling 10D of each of the plurality of floors. However, the installation position and number of the hoistway opening / closing parts 22 are not limited, and the temperature and humidity control system of the present embodiment may have at least one hoistway opening / closing part 22. For example, the hoistway opening / closing part 22 may also be provided on a side wall different from the side wall where the landing door 25 is provided. In addition, the hoistway opening / closing part 22 may also be provided on any one or more floors among the plurality of floors in the building 10.

[0042] The other end side of the duct 11 is connected to the uppermost hoistway opening / closing part 22. The duct 11 branches into a plurality of parts toward the plurality of hoistway opening / closing parts 22, and a duct 11A branched from the duct 11 is connected to each hoistway opening / closing part 22 except the uppermost hoistway opening / closing part 22. However, the connection structure of the hoistway opening / closing part 22 and the exhaust port 13 realized by the duct 11 is not limited to this. For example, it may be configured such that the duct does not have a branch, but a plurality of ducts are arranged, and the duct connects one hoistway opening / closing part 22 and the exhaust port 13. Or, it may be configured such that a plurality of ducts are arranged, and the duct has a branch connecting any two or more of the plurality of hoistway opening / closing parts 22 and the exhaust port 13.

[0043] Figure 3 It is a front view showing the hoistway opening / closing part. As Figure 3 shown, the hoistway opening / closing part 22 has a mechanical gate 26 that opens and closes the opening on the side wall surface of the hoistway 21 where the hoistway opening / closing part 22 is formed.

[0044] Figure 4 It is a diagram for explaining the operation when the hoistway opening / closing part changes from the closed state to the open state. In Figure 4 , a cross section of the hoistway opening / closing part 22 and its vicinity is shown. The left side shows the closed state, and the right side shows the open state. The gate 26 of the hoistway opening / closing part 22 opens when there is pressure due to the air flow from the duct 11. That is, the fan 12 operates, and an air flow A from the exhaust port 13 side toward the hoistway opening / closing part 22 side is generated in the duct 11. When the pressure on the duct 11 side is higher than the hoistway 21 side, the gate 26 opens. Thus, as Figure 4 shown, the air flow A flows from the hoistway opening / closing part 22 into the hoistway 21 side. In addition, in Figure 4 's opening / closing state, the gate 26 is housed inside the inner wall of the hoistway 21 or inside a protective plate with openings for ventilation, and is configured such that even if the gate 26 fails by any chance, it will not obstruct the lifting of the car 23.

[0045] Figure 5 It is a schematic diagram showing a comparison of the size of the exhaust port as the inlet of the duct and the opening where the hoistway opening / closing part is arranged. As Figure 5As shown, in the temperature and humidity control system of the present embodiment, the area of the exhaust port 13 that is the inlet of the duct 11 is formed to be larger than the cross-sectional area of the hoistway opening / closing part 22. That is, the flow path of the duct 11 connecting the exhaust port 13 and each hoistway opening / closing part 22 widens on the exhaust port 13 side and narrows on the hoistway opening / closing part 22 side.

[0046] In the present embodiment, it is assumed that the fan 12 is always powered and always operates, for example, during the service of the elevator 20. By the operation of the fan 12, an air flow stronger than the exhaust air volume of the fan 12 can be generated in the duct 11. By generating a strong air flow toward the hoistway opening / closing part 22 side in the duct 11, the air with stable temperature and humidity on the underground floor can be more strongly guided into the hoistway 21. Thus, the temperature and humidity of the entire hoistway 21 can be efficiently adjusted.

[0047] As described above, according to the temperature and humidity control system of the present embodiment, by operating the fan 12, the air with stable temperature and humidity on the underground floor can be guided into the hoistway 21 by a strong air flow. Thus, without using a physical connection mechanism, the temperature and humidity difference between the inside of the hoistway 21 and the landing 24 can be reduced, and the temperature and humidity difference between all the carriages 23 ascending and descending in the hoistway 21 and the building 10 side can be suppressed to be small. Therefore, the temperature and humidity management loads of the building manager and the elevator 20 manager can be reduced, and the loads such as maintenance inspections of the operator can also be reduced.

[0048] The temperature and humidity control system of the present embodiment directly conveys the air on the building 10 side into the hoistway 21, and while managing the temperature and humidity of the building 10, it can also manage the temperature and humidity inside the hoistway 21. Therefore, for example, when the external gas temperature becomes extremely high (e.g., 40°C or higher), extremely low (e.g., 0°C or lower), or extremely high humidity (e.g., 100% RH), the temperature and humidity of the hoistway 21 can be adjusted before the start of operation so that the elevator 20 can operate normally. Therefore, the building manager and the elevator manager can reduce the management load of the elevator 20, and can also reduce the loads such as maintenance inspections of the operator.

[0049] In addition, by operating the fan 12, the temperature and humidity adjustment inside the hoistway 21 can be automatically performed. Therefore, compared with the case of using a refrigeration and heating device for temperature and humidity adjustment of the carriage 23, the movable cables for power supply can be reduced, the environmental load can be reduced, and the power consumption of the carriage 23 of the elevator 20 can be significantly reduced. Thus, the temperature and humidity control system of the present embodiment can contribute to the achievement of SDGs (Sustainable Development Goals) or ZEB (Net Zero Energy Building).

[0050] In addition, in the present embodiment, the case where the exhaust port 13 is provided in the ceiling 10D of the basement floor and the air in the basement floor is introduced into the duct 11 has been described. Since the temperature and humidity of the air in the basement floor are relatively stable, the temperature and humidity in the shaft 21 can be effectively adjusted by guiding the air in the basement floor. However, the air inlet of the exhaust port 13, i.e., the duct 11, is not limited to the ceiling of the basement floor, and may be arranged in other places on the basement floor or other floors 10A. However, it is preferable that the exhaust port 13 is arranged in a space where the air with less temperature and humidity variation and stable, so as to be able to adjust the temperature or humidity in the shaft 21.

[0051] Embodiment 2

[0052] Figure 6 and Figure 7 FIG. is a diagram showing a car duct of the temperature and humidity control system according to Embodiment 2. Figure 6 The vertical cross-section of the car duct is shown, Figure 7 and the perspective three-dimensional view of the car duct and its vicinity is shown. The temperature and humidity control system according to Embodiment 2 has the same structure as the temperature and humidity control system according to Embodiment 1 except for having the car duct 30.

[0053] As Figure 6 and Figure 7 shown, the car duct 30 is arranged above the ceiling of the elevator car 23. The car duct 30 is a hollow member and has a blower section 32 surrounded by a heat insulating section 31. A car duct opening / closing section 33 is arranged at the inlet of the blower section 32. The positions of the shaft opening / closing section 22 and the car duct opening / closing section 33 of the car duct 30 are adjusted so that when the car 23 stops at the stop position on each floor 10A, the car duct opening / closing section 33 and the shaft opening / closing section 22 come to the opposing positions. The outlet 34 of the blower section 32 is connected to a ventilation opening 23C formed in the ceiling of the car 23.

[0054] A plurality of gates 35 are arranged in the car duct opening / closing section 33. The car duct opening / closing section 33 has the same mechanism as the shaft opening / closing section 22 arranged in the shaft 21, and is configured such that by the strong air flow from the shaft opening / closing section 22, the gates 35 of the car duct opening / closing section 33 are opened and the air flow A flows into the blower section 32. A position adjusting mechanism (not shown) may also be provided in the car duct opening / closing section 33 so that when the car 23 stops, the car duct opening / closing section 33 is opposed to the shaft opening / closing section 22. Thereby, the strong air flow can be reliably introduced into the car duct 30.

[0055] A wind direction changing section 37 is provided at the outlet of the air supply section 32. The wind direction changing section 37 has louver plates formed of a plurality of plate-like members. The orientation of the louver plates can also be changed automatically or manually. The air flow A flowing into the air supply section 32 is adjusted in its orientation by the wind direction changing section 37 and flows into the car 23. In addition, although not shown, the air in the car 23 pushed out by the air flow guided to the car 23 can be discharged through an exhaust fan (not shown) in the car 23.

[0056] As Figure 6 and Figure 7 shown, when the car 23 stops at a floor, the hoistway opening / closing section 22 and the car duct opening / closing section 33 are opened by the strong air flow A from the duct 11. Thereby, the air flow of the air on the building 10 side can spread from the air supply section 32 of the car duct 30 through the wind direction changing section 37 throughout the car 23. In addition, on the floors where the car 23 does not stop, air flow is supplied from the hoistway opening / closing section 22 into the hoistway 21. Thereby, the temperature and humidity in the entire hoistway 21 are also adjusted in the same manner.

[0057] As described above, according to the present embodiment, the entire hoistway 21 and the inside of the car can be cooled or heated, or the humidity can be adjusted by the air transported through the duct 11 from the basement floor. Thereby, the temperature and humidity difference between the car 23 and the landing can be effectively reduced, and the discomfort caused by the temperature and humidity difference can be reduced.

[0058] Embodiment 3

[0059] Figure 8 is a perspective three-dimensional view of the car duct of the temperature and humidity control system of the present embodiment. The temperature and humidity control system of the present embodiment has the same structure as that of the temperature and humidity control system of Embodiment 2, except that the car duct 40 has fins 41 in the air supply section and a high heat conductivity section on the inner wall of the car.

[0060] The air supply section of the car duct 40 is composed of a housing, which is composed of a rectangular parallelepiped portion 42 connected to the side of the car duct opening / closing section 33 at the inlet, and a fan-shaped column portion 44 connected to the surface of the rectangular parallelepiped portion 42 opposite to the side of the car duct opening / closing section 33.

[0061] Figure 9 is a perspective three-dimensional view showing the structure of the rectangular parallelepiped portion of the car duct. As Figure 9As shown, the fin 41 has a plurality of plate-like members within the rectangular parallelepiped portion 42 of the car duct 40, and the plurality of plate-like members are arranged at intervals parallel to the vertical direction and perpendicular to the opening surface of the car duct opening / closing portion 33. In addition, the upper and lower portions of the fin 41 are joined to the bottom surface 41A and the top surface 41B. The bottom surface 41A and the top surface 41B constitute the bottom surface and the top surface of the rectangular parallelepiped portion 42. Within the rectangular parallelepiped portion 42, the portion sandwiched between the plate-like members of adjacent fins 41 becomes a passage for the air introduced into the car duct 40. Additionally, in Figure 9 a fin shape is illustrated using a plurality of plate-like members arranged at intervals parallel to the vertical direction and perpendicular to the opening surface. However, since the purpose of the fin 41 is to transfer heat, as long as the shape has a high heat transfer rate from the air passage to the air in the air supply portion of the car duct 40, it is not limited to a plate shape and can be any shape.

[0062] In the present embodiment, the fin 41 of the car duct 40 is formed of a material with high thermal conductivity. In addition, the top surface 41B and the bottom surface 41A of the fin 41 are similarly formed of thick plates with high thermal conductivity.

[0063] As Figure 8 shown, the surfaces of the inner wall 23A on the side of the side wall of the car 23 close to the car duct 40 and the inner wall 23B of the front wall (i.e., the surface on the side opposite to the car door) become high thermal conductivity portions formed of a material with high thermal conductivity. A part of the inner wall 23A is connected to, for example, the bottom surface 41A of the fin 41. The connection portion between the inner wall 23A and the fin 41 is not limited to the bottom surface 41A, as long as heat coupling is performed via a plurality of high thermal conductivity members. Here, "heat coupling" means being directly or indirectly connected in a state with extremely low thermal resistance, and more specifically, for example, it means being coupled in a state where the thermal resistance is smaller than a specified target value.

[0064] In addition, a heat insulating portion 23D is disposed between the outer wall 23C supporting the car 23 and the inner walls 23A and 23B. The material of the heat insulating material constituting the heat insulating portion 23D is not limited.

[0065] In addition, a handrail 46 is provided on the inner wall 23A of the car 23. Here, similar to the inner walls 23A and 23B of the car 23, at least a part of the surface of the handrail 46 is formed of a material with high thermal conductivity. Specifically, the portion of the handrail 46 in contact with the inner wall 23A and the portion contacted by the user's hand are formed of a material with high thermal conductivity. It is also possible that the entire surface of the handrail 46 or the entire handrail 46 is formed of a material with high thermal conductivity.

[0066] In the present embodiment, the material having a high thermal conductivity that constitutes the fin 41 and the inner walls 23A and 23B of the car 23 is not limited. Examples of the material include aluminum or copper. When aluminum is used, for example, about 200 μm of the surface becomes alumina, but the high thermal conductivity is maintained inside the aluminum. When it is desired to maintain the metallic luster, an antioxidant or a discoloration inhibitor may be coated on the surface. The thickness of the alumina and the coating thickness of the antioxidant or the like are much thinner than the aluminum plate or the aluminum sheet, and thus the thermal resistance can be almost ignored. When copper is used, for example, a coating containing benzotriazole may be coated for oxidation prevention or discoloration prevention on the surface. In this case, oxidation and discoloration of the surface can be suppressed, and the high thermal conductivity inside the copper can be maintained. Similar to the oxide film of aluminum, the coating thickness is much thinner than the copper plate or the copper sheet, and thus the thermal resistance can be almost ignored.

[0067] In addition, it is assumed that the plate-like member of the fin 41 and the bottom surface 41A and the top surface 41B, the fin 41 and the inner wall 23A, and the inner wall 23A and the armrest 46 are thermally coupled using the same raw material. Here, an adhesive having a low thermal conductivity is not used. In addition, for example, when an oxide film or a coating film is formed on a material having a high thermal conductivity, as a pretreatment, the oxide film at the coupling portion is removed or thermal coupling is performed in a state where the coating film is not formed using a mask.

[0068] Figure 10 is a longitudinal sectional view of the inner wall of the front wall of the car. As Figure 10 shown, the surface of the inner wall 23B of the front wall of the car 23 has a shape with wavy irregularities in the longitudinal section.

[0069] Figure 11 is a sectional view for explaining the flow of air and the flow of heat transfer and heat conduction in the temperature and humidity control system of the present embodiment. Figure 11 shows a longitudinal section perpendicular to the landing door 25 of the car 23 and the car duct 40. In addition, in Figure 11 it, the air flow for heat transfer from the duct 11 is mainly indicated by the arrow A, and the flow of heat conduction, that is, heat conduction of the heat transferred from the air flow is mainly indicated by the arrow B.

[0070] As Figure 11As shown, the air flow A from the duct 11 flows into the car duct 40 and is guided from the outlet to the inside of the car 23 through the fins 41. At this time, the heat of the air flow is transferred to the fins 41, and the heat of the fins 41 is immediately conducted to the inner walls 23A, 23B and the handrail 46 connected to the inner wall 23A through heat conduction. In addition, in particular, the inner wall 23B close to the outlet of the duct 40 is also effectively temperature-controlled by the air flow flowing from the duct 40 into the car 23. In addition, the surface of the inner wall 23B is formed in unevenness. Therefore, the temperature transferred by the air flow flowing into the inner wall 23B can be effectively transferred to the whole inside of the car 23. Thereby, the temperature inside the car 23 can be made close to the building 10 side. Further, for example, a user riding in the car 23 directly grabs the handrail 46 with the hand C. Thus, the temperature close to the building 10 side can be immediately felt through heat conduction from the fins through the heat transfer of the flowing air flow. Thereby, the discomfort caused by the temperature difference between the building 10 side and the inside of the car 23 can be reduced more quickly. In addition, when the user approaches and touches the temperature-controlled inner wall 23A or 23B, the temperature close to the building side can be felt. Thereby, the discomfort caused by the temperature difference between the building side and the inside of the car can be reduced more quickly.

[0071] In addition, in the present embodiment, a temperature and humidity control system having the fins 41 in the car duct 40, the inner wall 23A connected to the fins 41, the front inner wall 23B, and the handrail 46 has been described. However, the temperature and humidity control system is not limited to having all of these structures, and may have any one or more of the inner walls 23A, 23B, and the handrail 46. In this case, the air temperature in the building can also be transferred to the car 23 with a certain degree of efficiency.

[0072] In addition, in the present embodiment, the case where only the inner wall 23A of the side wall close to the car duct 40 and the inner wall 23B of the front wall are made of a material with high heat conductivity has been described. However, the inner walls of the other side walls of the car 23 may also be formed of a material with high heat conductivity in the same manner. In addition, instead of the entire surface of each inner wall, only a part may be formed of a material with high heat conductivity. When the inner walls other than the inner walls 23A and 23B are also formed of a material with high heat conductivity, an adiabatic portion is also formed between the inner wall and the outer wall.

[0073] In addition, in the present embodiment, the case where only the inner wall 23B of the front wall is formed in a concavo-convex cross-sectional shape has been described. However, the inner wall 23A may also be formed in a concavo-convex shape. In addition, after the inner walls of the other side walls are formed of a material with high heat conductivity, they may be formed in a concavo-convex shape in the same manner as the inner wall 23B.

[0074] Embodiment 4

[0075] Figure 12It is a cross-sectional schematic view showing the temperature and humidity control system according to Embodiment 4 and its surroundings. Figure 12 It shows a longitudinal section of the building 10 as viewed from the front of the landing of the elevator 20. The temperature and humidity control system according to Embodiment 4 has the same structure as the temperature and humidity control system according to Embodiment 1, except that it has a control unit 50.

[0076] The control unit 50 also has the function of a control panel for controlling the operation of the elevator 20, and also functions as a temperature and humidity control device. The control unit 50 can control the operation of the fan 12. In addition, although not shown, the temperature and humidity control device can also be separated, and in this case, it communicates with the control unit for control. The setting of the reference values for the temperature and humidity control device described below is for temperature and humidity. The application of the reference values can also be for either or both of temperature and humidity. Hereinafter, the "first reference value" is the reference value for temperature, and the "second reference value" is the reference value for humidity. In addition, when it is set to "temperature and humidity", it means either or both of temperature and humidity, and in the case of "reference value", it means either or both of the first reference value and the second reference value.

[0077] Figure 13 It is a flowchart showing the control operation of the temperature and humidity control executed by the control unit 50. Use Figure 13 to explain the temperature and humidity control. For example, during the service of the elevator 20, it is repeatedly executed at a certain control interval Figure 13 of the flowchart.

[0078] As Figure 13 shown, first, in step S400, it is determined whether the difference between the temperature and humidity on the building 10 side and the temperature and humidity inside the car 23 is larger than the reference value. Here, when the reference value is set for both temperature and humidity, the temperature difference is compared with the first reference value, and the humidity difference is compared with the second reference value. When the reference value is set only for temperature, the temperature difference is compared with the first reference value, and when the reference value is set only for humidity, the humidity difference is compared with the second reference value. In the case of comparing both temperature and humidity, for example, when at least one of the case where the temperature difference is larger than the first reference value and the case where the humidity difference is larger than the second reference value is met, it is determined that the temperature and humidity difference is larger than the reference value. However, it can also be configured such that when the temperature difference is larger than the first reference value and the humidity difference is larger than the second reference value, it is determined that the temperature and humidity difference is larger than the reference value.

[0079] The temperature and humidity on the side of the building 10 are detected by a thermometer or a temperature and humidity sensor, etc., which is provided near the exhaust port 13 of, for example, a pipe 11 provided in the building 10. In addition, the temperature and humidity inside the car are detected by a thermometer or a temperature and humidity sensor, etc., which is provided in the car 23. However, the installation position of the unit for detecting the temperature and humidity is not limited to this. The reference value is an appropriately set temperature and humidity difference. In addition, although not shown in the drawings and the flowcharts, it may also be configured such that the reference value can be changed from the mobile interface according to the situation. The temperature and humidity difference set as the reference value can be set, for example, based on the boundary value at which a person feels uncomfortable. The mobile interface refers to the general term for these hardware or software having an interface that can be set by hardware such as a temperature and humidity adjustment button, a temperature and humidity adjustment switch, or software such as a PC (Personal Computer), a tablet (Tablet), a smart phone, a cellular phone, a wearable device such as a smart watch, a smart contact lens(es), and an eyewear device such as an AR glass (ArgmentedReality glass(es): virtual reality glasses). In addition, the mobile interface may be set as a part of the control unit or the temperature and humidity adjustment device. For example, a maintenance worker, etc., sets the boundary value that feels uncomfortable at the site as the reference value from the mobile interface and transmits the newly set reference value to the temperature and humidity adjustment device, thereby further setting the optimal reference value for each site.

[0080] When it is determined in step S400 that the temperature and humidity difference is equal to or less than the reference value, temperature and humidity adjustment is not required, so the current process ends. On the other hand, when it is determined in step S400 that the temperature and humidity difference is greater than the reference value, the process proceeds to step S402.

[0081] In step S402, the fan 12 operates. The control unit 50 sends a prescribed control signal to the fan 12 to cause the fan 12 to operate.

[0082] As described above, according to the present embodiment, by the control of the control unit 50, the temperature and humidity in the hoistway 21 are controlled, and the temperature and humidity difference between the side of the building 10 and the inside of the car 23 can be effectively suppressed.

[0083] In addition, in the present embodiment, the case where the control of the control unit 50 is applied to the temperature and humidity adjustment system of Embodiment 1 has been described. However, it is not limited to this, and the temperature and humidity adjustment control of the control unit 50 can also be applied to the temperature and humidity adjustment systems of Embodiment 2 or 3.

[0084] Embodiment 5

[0085] Figure 14 FIG. 5 is a cross-sectional schematic view showing the temperature and humidity control system according to Embodiment 4 and its surroundings. The temperature and humidity control system according to Embodiment 5 has the same structure as that of the temperature and humidity control system according to Embodiment 4, except that it has an electronically controlled hoistway opening / closing unit 51 instead of the hoistway opening / closing unit 22, and the control unit 50 controls the opening and closing of the hoistway opening / closing unit 51.

[0086] Figure 15 Schematically shows the operation when the hoistway opening / closing unit in the present embodiment opens and closes. In Figure 15 , the operation when changing from the closed state (upper side) to the open state (lower side) of the hoistway opening / closing unit 51 is shown. In addition, the front of the hoistway opening / closing unit 51 is shown on the left side, and the longitudinal section of the hoistway opening / closing unit 51 is shown on the right side thereof. In addition, in Figure 15 , the hoistway opening / closing unit 51 having a rectangular front shape is shown. However, the shape of the hoistway opening / closing unit 51 is not limited, and it may be circular or the like, for example. In addition, in Figure 15 , as the gate 52, a structure in which the gate becomes an open state for conveying air flow by sliding upward is shown. However, the opening / closing mechanism of the gate 52 is not limited thereto. The opening / closing mechanism of the gate 52 only needs to be able to become an open state for conveying air flow, and it may be opened in any direction of up, down, left, or right within a range that does not hinder the lifting of the elevator car. Alternatively, it may be a structure in which the gate 52 is rolled up or folded to become an open state. However, it is preferably that the gate 52 is housed in the hoistway wall or the protective plate so that in the event of a failure of the gate, the operation of the car 23 located in the hoistway 21 is not hindered.

[0087] As Figure 15 shown, the hoistway opening / closing unit 51 provided on the wall surface of the hoistway 21 has a gate 52. The opening / closing operation of the gate 52 is controlled by the control unit 50. As Figure 14 shown, the gate 52 slides upward according to a signal from the control unit 50, whereby the hoistway opening / closing unit 51 opens. As a result, the air from the duct 11 can be guided to the hoistway 21 side.

[0088] The control unit 50 has the function of an elevator control panel that controls the operation of the hoistway opening / closing unit 51 and controls the operation of the elevator car. The control unit 50 is connected via a car communication cable 53 so as to be able to transmit and receive signals with the car 23. The control unit 50 functions as a temperature and humidity control device and performs the following temperature and humidity control: when the temperature difference between the temperature and humidity in the car 23 and the building 10 side is greater than the first reference value or the humidity difference is greater than the second reference value and the elevator 20 is in a specified mode, the temperature and humidity in the car 23 are adjusted.

[0089] Figure 16 is a flowchart for explaining the control operation of the temperature and humidity adjustment control executed by the control unit 50. Use Figure 16 to explain the temperature and humidity adjustment control in the present embodiment. For example, in the service of an elevator, the control operation Figure 16 is repeatedly executed at a certain control interval.

[0090] Specifically, as Figure 16 shown, first, in step S500, it is determined whether the difference between the temperature and humidity on the building side and the temperature and humidity in the car is larger than the reference value. Here, when the reference value is set for both temperature and humidity, the temperature difference is compared with the first reference value, and the humidity difference is compared with the second reference value. When the reference value is set only for temperature, the temperature difference is compared with the first reference value. When the reference value is set only for humidity, the humidity difference is compared with the second reference value. In the case of comparing both temperature and humidity, for example, when at least one of the case where the temperature difference is larger than the first reference value and the case where the humidity difference is larger than the second reference value is satisfied, it is determined that the temperature and humidity difference is larger than the reference value. However, it can also be configured that when the temperature difference is larger than the first reference value and the humidity difference is larger than the second reference value, it is determined that the temperature and humidity difference is larger than the reference value.

[0091] The temperature and humidity on the building 10 side are detected by a temperature and humidity meter or a temperature and humidity sensor, etc., provided near the exhaust port 13 of, for example, the duct 11 provided in the building 10. In addition, the temperature and humidity in the car are detected by a temperature and humidity meter or a temperature and humidity sensor, etc., provided in the car 23. However, the installation position of the unit for detecting temperature and humidity is not limited to this. The reference value is a temperature and humidity difference appropriately set in advance. In addition, although not shown in the drawings and the flowchart, it can also be configured that the reference value can be changed from the above-mentioned mobile interface according to the situation. The temperature and humidity difference set as the reference value can be set, for example, according to the boundary value at which people feel uncomfortable.

[0092] When it is determined in step S500 that the temperature and humidity difference is equal to or less than the reference value, temperature and humidity adjustment is not required, so the current process ends. On the other hand, when it is determined in step S500 that the temperature and humidity difference is larger than the reference value, the process proceeds to step S502.

[0093] In step S502, it is determined whether the elevator 20 is in a specified mode. Here, the specified mode is a specific mode indicating that the car 23 is in a state where the temperature and humidity can be adjusted, and the specific conditions can be appropriately set in advance. Specifically, for example, the specified mode is that the car 23 is in a standby state on any floor.

[0094] If it is determined in step S502 that the elevator 20 is not in the specified mode, the current process ends. On the other hand, if it is determined in step S502 that the elevator 20 is in the specified mode, the process then proceeds to step S504.

[0095] In step S504, the operation of the fan 12 starts, and the hoistway opening / closing part 51 opens. In addition, the temperature and humidity control system has the hoistway opening / closing part 51 on each floor 10A. However, here, only the hoistway opening / closing part 51 corresponding to the floor 10A where the car 23 in the specified mode is stopping opens. As a result, the air flow from the duct 11 strongly flows only into the hoistway opening / closing part 51 near the floor 10A where the car 23 in the standby state is stopping. Therefore, the air on the building 10 side can be effectively transported into the car 23 at the stop floor. Thus, the air in the car 23 is efficiently ventilated by the air flow from the duct 11, and the temperature and humidity in the car 23 are regulated.

[0096] Next, it is determined whether there is a call for the car 23. The call for the car 23 is input through an operation panel or the like for call registration provided at the landing 24 and is sent to the control panel, i.e., the control unit 50, of the elevator 20.

[0097] If it is determined in step S506 that there is no call, the process returns to step S506. The hoistway opening / closing part 51 remains open, and the determination process of step S506 is repeatedly performed at regular intervals until it is determined in step S506 that there is a call. On the other hand, if it is determined in step S506 that there is a call, the process proceeds to step S508.

[0098] In step S508, a release instruction for the specified mode is issued. In step S510, upon receiving the release instruction, the operation of the fan 12 stops, and the hoistway opening / closing part 51 opened in step S504 returns to the closed state.

[0099] In step S512, the release of the specified mode is completed. Then, in step S514, the car 23 returns to the normal mode. Thus, the car 23 becomes a state where it can perform normal operation and respond to the registered calls. Then, the current process ends.

[0100] As described above, in the present embodiment, when the car 23 is in the specified mode in which temperature and humidity can be adjusted, only the hoistway opening / closing part 51 corresponding to the standby position of the car 23 opens. As a result, for the car 23 in the specified mode, the air flow from the building 10 side of the duct 11 can be strongly introduced into the car 23. Thus, the temperature and humidity in the car 23 can be effectively adjusted.

[0101] In addition, in the present embodiment, the fan 12 operates for temperature and humidity adjustment only when the temperature and humidity difference between the building 10 side and the car 23 side is large and the car 23 is in a specified mode. It is not necessary to always operate the fan 12, so the amount of power consumed during the time when the fan 12 is not operating can be reduced. However, the execution conditions for the temperature and humidity adjustment control are not limited to this. For example, control may be performed such that the hoistway opening / closing portion 51 is opened regardless of the temperature and humidity difference between the building 10 side and the car 23 side when the car 23 is in a specified mode.

[0102] In addition, in the present embodiment, for temperature and humidity adjustment control, an electric hoistway opening / closing portion 51 that opens and closes according to an instruction from the control unit 50 is provided. Generally, the airtightness of the electric hoistway opening / closing portion 51 is higher than that of the mechanical hoistway opening / closing portion 22. Therefore, air leakage from the duct 11 can be suppressed, and the air on the building 10 side can be more strongly conveyed only to the open hoistway opening / closing portion 51.

[0103] In addition, in the present embodiment, the case where the temperature and humidity adjustment control of the control unit 50 is applied to the temperature and humidity adjustment system having the structure described in Embodiment 1 has been described. However, the present invention is not limited to this. For example, the temperature and humidity adjustment control of the control unit 50 can be applied to the temperature and humidity adjustment system having a car duct shown in Embodiment 2 or 3. In this case, it may also be configured such that the same electric opening / closing mechanism as that of the hoistway opening / closing portion 51 is applied to the car duct opening / closing portion described in Embodiment 2 or 3, and the control unit 50 controls the opening and closing of the car duct opening / closing portion so as to open and close at the same timing as the hoistway opening / closing portion 51. By applying the temperature and humidity adjustment control of the present embodiment to the temperature and humidity adjustment system of Embodiment 2 or 3, the temperature and humidity inside the car 23 can be adjusted more effectively.

[0104] Embodiment 6

[0105] Figure 17 FIG. is a cross-sectional schematic view showing the temperature and humidity adjustment system according to Embodiment 6 and its surroundings. Figure 17 FIG. shows a longitudinal section of the building 10 as viewed from the front of the landing of the elevator 20. Except for the fact that the building 10 is provided with a refrigerating and heating device 54, Figure 15 the temperature and humidity adjustment system has the same structure as the temperature and humidity adjustment system of Embodiment 5.

[0106] The refrigeration and heating device 54 cools and heats the air in the indoor area of the basement floor, or controls the humidity, and is installed on the ceiling 10D of the basement floor. That is, in the present embodiment, the exhaust port 13 of the duct 11 is provided on the ceiling 10D of the basement floor, and the refrigeration and heating device 54 is provided near the exhaust port 13. However, the installation position of the refrigeration and heating device 54 in the temperature and humidity adjustment system is not limited to the ceiling 10D of the basement floor, and it may be installed at other positions as long as it can cool and heat the air near the exhaust port 13 of the duct 11.

[0107] In the present embodiment, similar to Embodiment 5, the control unit 50 performs the following temperature and humidity adjustment control: when the difference between the temperature and humidity in the car and the temperature and humidity on the building 10 side is greater than the reference value and the car 23 is in a specified mode, the temperature and humidity in the car 23 are adjusted. However, in the present embodiment, when the refrigeration and heating device 54 is in operation and the car 23 is in a specified mode, the temperature and humidity in the car 23 are adjusted, which is different from the control of the temperature and humidity adjustment system in Embodiment 5.

[0108] Figure 18 It is a diagram showing the control conditions in the temperature and humidity adjustment control of the temperature and humidity adjustment system of the present embodiment. Figure 18 In the column of "specified mode", "ON (turned on)" is used to indicate that the elevator 20 is in the specified mode, and "OFF (turned off)" is used to indicate that it is not in the specified mode. In addition, in the column of "refrigeration and heating device", it is shown whether the refrigeration and heating device 54 is in the "operating" state or the "stopped" state. In addition, in the column of "state of the hoistway opening / closing part", it is shown whether the hoistway opening / closing part 51 corresponding to the floor where the car 23 stops becomes the "open" state or the "closed" state.

[0109] As Figure 18 As shown in states 2, 3, and 4, when at least one of the case where the specified mode of the elevator 20 is off and the case where the refrigeration and heating device 54 stops is satisfied, the hoistway opening / closing part 51 corresponding to the floor 10A where the car 23 stops does not open and becomes the closed state. On the other hand, as shown in state 1, when the specified mode is on and the refrigeration and heating device 54 is in operation, the hoistway opening / closing part 51 corresponding to the floor where the car 23 stops opens.

[0110] Figure 19 It is a flowchart showing the control operation of the temperature and humidity adjustment control executed by the control unit 50. Use Figure 19 to explain the temperature and humidity adjustment control of the present embodiment. Except that there is a process of step S600 before step S500, Figure 19 the flowchart of Figure 16 is the same as the flowchart ofFigure 16 The description of the repeated processing in the flowchart is omitted.

[0111] In Figure 19 In the temperature and humidity adjustment control shown, first, in step S600, it is determined whether the refrigeration and heating device 54 is in operation. If it is determined in step S600 that the refrigeration and heating device 54 is stopped, the current process ends. On the other hand, if it is determined in step S600 that the refrigeration and heating device 54 is in operation, the process proceeds to step S500. Then, as described in Embodiment 5, the processes of steps S500 to S514 are appropriately performed.

[0112] As described above, when the refrigeration and heating device 54 on the basement floor where the exhaust port 13 is formed is in operation, the temperature and humidity adjustment system of this embodiment performs temperature and humidity adjustment control of the car 23. Thus, air with stable temperature and humidity due to refrigeration and heating can be delivered into the hoistway 21, and stable temperature and humidity adjustment of the car 23 can be performed.

[0113] In addition, similar to the case of Embodiment 5, the temperature and humidity adjustment control of this embodiment is not limited to the temperature and humidity adjustment system having the structure described in Embodiment 1, and can also be applied to the temperature and humidity adjustment system having car ducts shown in Embodiment 2 or 3. In this case, the refrigeration and heating device may be arranged to refrigerate and heat the air in the space of the exhaust port 13 where the duct 11 is formed. By applying the temperature and humidity adjustment control of this embodiment to the temperature and humidity adjustment systems of Embodiments 2 and 3 having car ducts 30 and 40, more effective temperature and humidity adjustment inside the car 23 can be performed. In addition, when only the temperature and humidity of the indoor of the building are controlled by the refrigeration and heating device in the building, by using its exhaust gas, the temperature and humidity difference inside the elevator car 23 can also be reduced. Thus, the refrigeration and heating device may not be provided on the elevator side.

[0114] Embodiment 7

[0115] Figure 20 FIG. is a cross-sectional view for explaining the temperature and humidity adjustment system of Embodiment 7. The temperature and humidity adjustment system of this embodiment has the same structure as the temperature and humidity adjustment system of Embodiment 6, except that the exhaust port of the duct 55 of the temperature and humidity adjustment device is provided at any place inside or outside the building 10 and a refrigeration and heating device 56 is provided opposite to the exhaust port instead of the fan 12.

[0116] As Figure 20As shown, the exhaust port 57 of the duct 55 is arranged to face the air outlet of the air-conditioned air by the refrigeration and heating device 56. The installation position of the refrigeration and heating device 56, that is, the position of the exhaust port 57 of the duct 55, is not limited, and it may be installed at any place inside or outside the building 10. A fan 58 is built in the refrigeration and heating device 56. It is configured that the air-conditioned air by the refrigeration and heating device 56 directly flows into the duct 55 through the fan 58. There is no need to newly install a fan different from the refrigeration and heating device 56 of the building 10. In addition, similar to the case of the first embodiment, the duct 55 is configured such that its flow path cross-section becomes larger on the exhaust port 57 side and smaller on the hoistway opening / closing part 51 side.

[0117] The temperature and humidity control system of the present embodiment performs temperature and humidity control in the same manner as the sixth embodiment. Thus, the air-conditioned air by the refrigeration and heating device 56 can be directly guided into the car 23. Therefore, the temperature and humidity of the car 23 can be effectively adjusted.

[0118] In addition, in the present embodiment, the case where the duct 55 and the refrigeration and heating device 56 are provided instead of the duct 11 and the fan 12 of the structure of the first embodiment is described. However, the structure of the duct 55 and the refrigeration and heating device 56 can also be applied instead of the duct 11 and the fan 12 of the temperature and humidity control system of the second or third embodiment.

[0119] The preferred embodiments and the like have been described in detail above. However, it is not limited to the above embodiments and the like, and various modifications and substitutions can be made to the above embodiments without departing from the scope described in the claims.
