Description

  The present invention relates to an indoor temperature control system capable of reducing the electric power required for controlling the indoor temperature and maintaining the indoor temperature distribution in a desired temperature range close to a uniform state.

Conventionally, in thermal power plants and nuclear power plants, control equipment such as power generation equipment is housed in the building room and managed in a lump. In such a room, control equipment overheats and operates smoothly. Therefore, it is necessary to keep the room temperature within a certain range.
Normally, control equipment is composed of complicated electronic circuits and often generates heat, and there is a limit to cooling by heat dissipation in a room where such control equipment is assembled. It was necessary to cool the control equipment.
Moreover, when the room temperature is excessively low, the control device may not operate normally. In this case, it is necessary to keep the control device at an appropriate temperature by heating.
Normally, when air conditioning equipment is used, room air is agitated only by cold wind or warm wind supplied from the air conditioning equipment, so in a room where the control equipment stands, warm and cold air can reach every corner of the room. There was a problem that it was out of reach. On the other hand, in order to solve such problems, there is a method in which a fan or the like is provided separately from the air conditioning equipment in the room where the control equipment is installed, and the room air is constantly stirred. Since they are not linked, it is not preferable to operate the fan when it is not necessary to agitate the room air, resulting in power loss.
The invention having the same technical contents as the present invention has not been found at present, but the prior art for controlling the indoor temperature by installing a plurality of temperature sensors in the room and using the measured values is as follows. It has been known.

Patent Document 1 has the name “vehicle air conditioner” and automatically detects the temperature inside the vehicle, controls the operation of the air conditioner based on the signal, and maintains the optimum temperature inside the vehicle. An invention relating to an air conditioner is disclosed.
An air conditioner for a vehicle that is an invention disclosed in Patent Document 1 is an air conditioner for a vehicle in which operation control of the air conditioner is performed by a thermostat installed at an appropriate position in the vehicle, in the vicinity of the air conditioner. The temperature difference detection device is installed near the ceiling and the floor in the car, and the temperature difference near the ceiling and the floor The temperature difference is detected, and one of the different set values of the thermostat is selected by the output signal.
According to the invention disclosed in Patent Literature 1, it is possible to switch the operation mode of the vehicle air conditioner by determining the passenger accommodation status in the vehicle from the temperature difference between the vicinity of the ceiling and the floor in the vehicle. . Therefore, it is possible to provide a comfortable room temperature for passengers regardless of whether the interior of the vehicle is full or full.

Patent Document 2 discloses an invention relating to an indoor unit of an air conditioner that adjusts the indoor temperature to a comfortable temperature by cooling or heating under the name of “indoor unit of air conditioner”.
The indoor unit of an air conditioner that is an invention disclosed in Patent Document 2 is directed to the direction in which air is blown from the main body according to the temperature measured by temperature sensors provided at a plurality of locations in the room and the set temperature. In addition to controlling the vertical and horizontal directions, the air flow can also be controlled.
According to the invention disclosed in Patent Document 2 having the above configuration, when there is a variation in temperature distribution in the room, the supply direction and the supply amount of cold air or warm air are automatically adjusted so as to correct the variation. As a result, the temperature in the room can be homogenized.

  However, according to the invention disclosed in Patent Document 1, although the mode of the air conditioning equipment can be switched according to the situation in the vehicle, the only thing that stirs the air in the vehicle is the wind power supplied from the duct. Therefore, it was not technical content to positively correct the variation in temperature distribution in the vehicle.

  Further, the invention disclosed in Patent Document 2 is not the technical content of forcibly stirring the indoor air to correct the variation in temperature distribution.

The inventions disclosed in Patent Documents 1 and 2 are both inventions related to air conditioning equipment for indoor spaces where people live. In this case, the strong air flow in the room is suitable for making the room temperature uniform, but there is also a possibility of giving an uncomfortable feeling to a person in the room. For this reason, there existed a situation that a ventilation installation cannot be actively utilized indoors.
However, when what is accommodated in the room is a “thing” such as a control device and not a “person”, there is no need to consider discomfort caused by a strong air flow. On the other hand, the air-conditioning equipment used in the room for installing such control equipment is usually also used as the air-conditioning equipment for living space. There was a problem that the temperature could not be adjusted efficiently.

  The present invention has been made in response to such a conventional situation, and an object of the present invention is to efficiently and power-saving the temperature adjustment in a room that accommodates a control device or the like while using an air conditioner for a human living space.

From the measured value When the difference between the two measured values selected as desired is equal to or smaller than the first set value, a stop signal is transmitted to the fan, and the measurement values detected by the plurality of temperature sensors are calculated in the arithmetic processing unit. When the average value is calculated and the average value is out of the range of the second set value set in advance as desired, an operation signal is transmitted to the air conditioning equipment, and the average value is within the range of the second set value. In this case, a stop signal is transmitted to the air conditioning equipment.
In the invention with the above configuration, the temperature sensor has an effect of detecting room temperature at various heights in the room. Further, the air conditioning equipment has an action of supplying warm air or cold air into the room. Furthermore, the fan has an action of stirring the air in the room to make the room temperature uniform. And a control part has the effect | action of transmitting a control signal with respect to an air conditioner and a fan. In addition, the arithmetic processing unit has an operation of obtaining a difference between the measurement values obtained by combining the measurement values detected by the plurality of temperature sensors, and an operation of obtaining an average value of the detected measurement value group. .
When the difference between two measurement values selected as desired from the measurement values detected by the plurality of temperature sensors exceeds a first setting value set in advance as desired, an operation signal is sent to the fan. Is transmitted to actuate the fan, so that the temperature distribution in the room becomes uniform.
Further, when the difference between two measurement values selected as desired from the measurement values detected by the plurality of temperature sensors is equal to or smaller than a first setting value set in advance, a stop signal is sent to the fan. By transmitting, the operation of the fan is stopped and the power for driving the fan is saved. At this time, an average value of the measured values detected by the plurality of temperature sensors is obtained, and if this average value deviates from the second set value set as desired, an operation signal is sent to the air conditioning equipment When the average value is within the range of the second set value set as desired, a stop signal is transmitted to the air conditioning equipment to minimize the use of the air conditioning equipment. However, it has the effect of maintaining the indoor temperature within the range of the second set value set in advance as desired.

An indoor temperature control system according to a second aspect of the present invention is the indoor temperature control system according to the first aspect, wherein the plurality of temperature sensors are arranged at a plurality of locations in the same elevation in the room, and the plurality of temperature sensors. Instead of each of the measurement values detected by the above, each of the average values of the measurement values detected by a plurality of sensors disposed in the same elevation in the room is used.
In addition to the same function as that of the first aspect of the invention, the invention with the above configuration improves the accuracy of detecting the variation in the temperature distribution in the room by disposing a plurality of temperature sensors at a plurality of locations in the same elevation in the room. It has the action. Moreover, since the detection accuracy of the variation in the temperature distribution in the room is increased, the fan and the air conditioning equipment are frequently switched on and off, so that the uniformity of the room temperature is improved compared to the case of the invention according to claim 1. Has an effect.

According to the indoor temperature control system of the first aspect of the present invention, the indoor temperature is maintained within the range of the second set value set in advance as desired while minimizing the operation of the fan and the air conditioning equipment. Can do. Moreover, the difference between the maximum temperature and the minimum temperature in the temperature distribution in the room at that time can be made equal to or less than the first set value set in advance as desired.
As a result, the control device accommodated in the room can be maintained within the range of the second set value, so that the control device can be operated safely.

  An indoor temperature control system according to an embodiment of the present invention will be described in detail with reference to Example 1 and Example 2.

The indoor temperature control system according to the first embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.
FIG. 1 is a conceptual diagram of an indoor temperature control system according to Embodiment 1 of the present invention.
First, the arrangement of each component in the indoor temperature control system 1A will be described with reference to FIG.
As shown in FIG. 1, an indoor temperature control system 1A according to the first embodiment is arranged such that a plurality of control devices 3 stand in a room 2 of a building. 4 and a fan 5 is provided on the ceiling. Further, the wall surface 2a of the room 2 has a plurality of (at least two or more) temperatures while changing the height (elevation) in the vertical direction from the floor surface 2b. Sensors 6 to 8 are provided. The air conditioner 4, the fan 5, and the temperature sensors 6 to 8 are all wired or wirelessly connected to the control unit 9 disposed outside the room 2 or the room 2, and from the temperature sensors 6 to 8. A control signal is transmitted from the control unit 9 to the air conditioning equipment 4 and the fan 5 by wire or wireless based on the detected value of the indoor 2 temperature transmitted to the control unit 9 by wire or wirelessly. ing. The control unit 9 includes an arithmetic processing unit 10 inside or outside.
The control device 3 housed in the room 2 is for smoothly and safely operating various devices used for power generation in a power generation plant using nuclear power, thermal power or hydraulic power. In order to make it smooth, it was necessary to perform temperature management appropriately in the room 2.
In addition, here, as shown in FIG. 1, as an example of the arrangement of the temperature sensors, a case where the temperature sensors are arranged at three locations while changing the elevation on the wall surface 2 a of the room 2 will be described as an example. More specifically, in the indoor temperature control system 1A according to the first embodiment, the temperature sensor 6 is located near the ceiling of the room 2, the temperature sensor 7 is located near the floor 2b, and the temperature sensor 6 and the temperature sensor 7 are intermediate. A temperature sensor 8 is provided at the position.

Next, a procedure for controlling the temperature of the room 2 by the room temperature control system 1A according to the first embodiment will be described with reference to FIGS.
FIG. 2 is a flowchart showing a control process of the indoor temperature control system according to the first embodiment of the present invention. In addition, the same code | symbol is attached | subjected about the part same as what was described in FIG. 1, and the description about the structure is abbreviate | omitted.
As shown in FIG. 2, first, room temperature is measured (detected) by the temperature sensors 6 to 8 disposed in the room 2 (step S01), and the detected value is transmitted to the control unit 9. And in the arithmetic processing part 10 connected to the control part 9, the difference of two measured values selected from the measured values by the temperature sensors 6-8 is calculated | required by arithmetic processing, and this difference is beforehand made desired. When compared with the first set value to be set (step 02) and exceeds the first set value, an operation signal is transmitted from the control unit 9 to the fan 5, and the fan 5 is driven. (Step S03). On the other hand, when the difference between the measured values obtained by the temperature sensors 6 to 8 obtained in the arithmetic processing unit 10 is less than that when compared with the first set value (step 02), the control unit 9 A stop signal is transmitted from the fan 5 to the fan 5, and the fan 5 is stopped (step S04).

Here, detailed description will be added to steps S01 to S04.
When the control device 3 is accommodated in the room 2, the control device 3 is usually composed of a complicated electronic circuit and often generates heat, so that the air conditioner 4 is operated or not movable in the room 2. The temperature distribution in the room 2 varies.
In addition, when the temperature rises locally in the control device 3, it is desirable that the control device 3 is suitably cooled for smooth operation of the control device 3, but the room 2 measured at a plurality of locations is preferable. When switching between operation and stop of the air conditioning equipment 4 on the basis of the average value of the temperature, even if it is desirable to operate the air conditioning equipment 4, the temperature is locally high and the temperature locally May be erroneously determined to be within an appropriate range because the average value of the temperature in the room 2 is erroneously offset. In this case, there is a problem that the air conditioning equipment 4 does not operate and the heat load on the control device 3 is not reduced.
In view of such circumstances, in the room temperature control system 1A according to the first embodiment, the air in the room 2 is forcibly stirred by the fan 5 to correct the variation in the temperature distribution in the room, and the temperature of the room 2 Is within the range of the first set value set in advance as desired.
Therefore, the room temperature control system 1A according to the first embodiment is configured such that the temperature around the control device 3 accommodated in the room 2 is not conceptual but can be brought close to an ideal temperature range.

More specifically, first, in step S01, the temperature at each elevation in the room 2 is detected by the temperature sensors 6 to 8 in FIG.
Then, in the next step S02, in the arithmetic processing unit 10, the difference between the detection values of the temperature sensors 6, 7 is the difference between the detection values of the temperature sensors 6, 8, and the difference between the detection values of the temperature sensors 7, 8 ( (Arithmetic difference) is obtained, and all the arithmetic differences are compared with the first set value in the control unit 9. If at least one of the arithmetic differences exceeds the first set value, the temperature distribution in the room 2 In step S03, an operation signal is transmitted from the control unit 9 to the fan 5 so that the fan 5 is actuated so as to correct the room temperature variation in the room 2. Thereby, the air in the room 2 is agitated, and the variation in the temperature distribution in the room 2 is corrected.
On the other hand, in the previous step S02, if the arithmetic difference obtained by the arithmetic processing unit 10 is equal to or less than the first set value, the variation in the temperature distribution of the temperature in the room 2 is determined to be within the allowable range, and the control is performed. A stop signal is transmitted from the section 9 to the fan 5. That is, when the fan 5 is operating, it is stopped, and when the fan 5 is stopped, the stopped state is maintained as it is.
In the first embodiment, the process proceeds to the step of determining whether or not the temperature in the room 2 is appropriate only when the variation in the temperature distribution in the room 2 is reduced to some extent.

Next, the steps after step S04 will be described in detail with reference to FIG.
In the indoor temperature control system 1A according to the first embodiment, after the variation in the temperature distribution in the room 2 is within an allowable range, the average value of the detection values in the temperature sensors 6 to 8 is calculated in the arithmetic processing unit 10, It is recognized as the temperature of the room 2 at that time (step S05). In the previous step, the variation in the temperature distribution in the room 2 has been sufficiently corrected, so that the temperature in the room 2 can be regarded as approximating the average value obtained in step S05.
Next, the control unit 9 compares the average value of the temperature in the room 2 obtained in step S05 with a second setting value set in advance as desired (for example, a numerical range having a certain range). When the average value of the room temperature is outside the range of the second set value, it is determined that the temperature in the room 2 is not in an appropriate state (step S06), and the operation signal is sent from the control unit 9 to the air conditioning equipment 4. Is transmitted and the air conditioning equipment 4 is activated (step S07).
On the other hand, when the average value of the room temperature is within the range of the second set value, it is determined that the temperature in the room 2 is in an appropriate state (step S06), and the control unit 9 applies to the air conditioning equipment 4. When the stop signal is transmitted and the air conditioner 4 is operating, the air conditioner 4 is stopped, and when the air conditioner 4 is stopped, the state is maintained (step S08).

According to the indoor temperature control system 1A according to the first embodiment as described above, by providing the temperature sensors 6 to 8, the control unit 9, and the fan 5, the temperature of the room 2 is minimized while the operation of the fan 5 is minimized. Can be made uniform by reducing the variation of the. More specifically, the variation in the temperature distribution of the temperature in the room 2 can be made smaller than the first set value.
In addition, according to the indoor temperature control system 1A, by providing the temperature sensors 6 to 8, the control unit 9, and the air conditioning equipment 4, the temperature of the indoor 2 is kept within an appropriate temperature range while minimizing the operation of the air conditioning equipment 4. Can be maintained.
Therefore, according to the invention described in the first embodiment, the temperature in the room 2 can be kept uniform within a desired temperature range, and the power consumption of the air conditioning equipment 4 and the fan 5 at that time can be minimized. be able to.
Further, although various control devices 3 having various dimensions are arranged in the room 2, by providing such an indoor temperature control system 1A, the temperature difference between the sensors can be lowered as desired. It is not necessary to arrange the sensors in consideration of the arrangement of the control device 3 separately for each, and the sensors can be arranged uniformly. On the other hand, by setting the first set value and the second set value for each room, individual air conditioning control for each room is also possible. That is, both versatility and exclusiveness can be exhibited.

In the indoor temperature control system 1A according to the first embodiment, as shown in FIG. 1, as an example, the elevation is changed on the wall surface 2a of the room 2 and the temperature sensors 6 to 8 are provided at three locations. However, it is also possible to arbitrarily select a plurality of places in the room 2 that are susceptible to the influence of the air conditioning equipment 4 and places that are difficult to receive, and install temperature sensors in all of them. In this case, the variation in the temperature distribution in the room 2 can be corrected more efficiently.
Moreover, you may make the number of the blower outlets of the fan 5 and the air conditioning equipment 4 provided in the room 2 into one or more. Also in this case, the variation in the temperature distribution in the room 2 can be corrected more efficiently.
The indoor temperature control system 1A according to the first embodiment is not an indoor temperature control system for the room 2 that is a living space of a person, but an indoor temperature control system for the room 2 for accommodating the control device 3. It is not necessary to consider whether the air flow generated by the fan 5 is pleasant or unpleasant to humans.
For this reason, the air around the control device 3 accommodated in the room 2 can be kept in an appropriate temperature range by the air conditioning equipment 4 while being efficiently stirred by the fan 5 as necessary.
Therefore, troubles due to overheating of the control device 3 accommodated in the room 2 and occurrence of problems can be prevented.

Hereinafter, the indoor temperature control system according to the second embodiment will be described in detail with reference to FIGS. 3 and 4. First, the configuration of an indoor temperature control system 1B according to the second embodiment will be described with reference to FIG.
FIG. 3 is a conceptual diagram of an indoor temperature control system according to Embodiment 2 of the present invention. In addition, the same code | symbol is attached | subjected about the same part as what was described in FIG. 1 or FIG. 2, and the description about the structure is abbreviate | omitted.
The indoor temperature control system 1B according to the second embodiment has substantially the same configuration as the indoor temperature control system 1A shown in FIG. 1, but a temperature sensor is arranged at each of a plurality of locations of the same elevation in the room 2. All of these temperature sensors are connected to the control unit 9 by wire or wirelessly.
More specifically, temperature sensors 6a and 6b are provided at, for example, two locations near the ceiling in the wall surface 2a of the room 2, temperature sensors 7a and 7b are provided at, for example, two locations on the wall surface 2a in the vicinity of the floor surface 2b, and the temperature. Temperature sensors 8a and 8b are provided at two positions, an intermediate position between the sensors 6a and 7a and an intermediate position between the temperature sensors 6b and 7b, respectively.
In FIG. 3, the case where two temperature sensors are provided in the same elevation is described as an example, but the number of temperature sensors may be two or more.
In particular, when the room 2 is wide, a large number of temperature sensors may be arranged in the same elevation according to the size of the room 2.
In the indoor temperature control system 1B according to the second embodiment, the mounting position of the temperature sensor is described as “same elevation”, which includes substantially the same concept and is strictly the same. There is no need.

Next, a procedure for controlling the temperature of the room 2 by the room temperature control system 1B according to the second embodiment will be described with reference to FIGS.
FIG. 4 is a flowchart showing a control process of the indoor temperature control system according to the second embodiment of the present invention. The same parts as those described in FIGS. 1 to 3 are denoted by the same reference numerals, and description of the configuration is omitted.
The procedure for controlling the temperature of the room 2 by the room temperature control system 1B according to the second embodiment is almost the same as the procedure in the room temperature control system 1A according to the first embodiment described above. A reference is attached.
More specifically, the indoor temperature control system 1B according to the second embodiment is compared with the indoor temperature control system 1A according to the first embodiment between the step S01 and the step S02 in the flowchart shown in FIG. The difference is that step S09 is provided.
In the indoor temperature control system 1A according to the first embodiment, since only one temperature sensor is provided for each elevation, the measured values detected by the plurality of temperature sensors 6 to 8 in step S02. An arithmetic difference was obtained for each of the two measured values selected as desired from the above, and compared with the first set value. As the number of temperature sensors increased, the desired value was obtained from the set of detected values obtained from the temperature sensors. The number of combinations for selecting these two detection values increases geometrically, and the calculation processing becomes complicated.
In view of such circumstances, in the indoor temperature control system 1B according to the second embodiment, a separate step S09 is provided between the step S01 and the step S02 in the flowchart of the work process as shown in FIG. 4), an average value of the temperature sensors provided in each elevation is obtained, and this average value is regarded as a measured value in the elevation.
Note that, on the wall surface 2a in the same elevation in the room, the air blowing state from the air conditioning equipment 4 and the fan 5 is usually similar, so that it is rare that the measured value by the temperature sensor varies greatly. Therefore, compared with the case where the measured values of room temperature in different elevations are averaged, there is a possibility that the detection accuracy of the variation in the temperature distribution of the room temperature is reduced when the measured values of room temperature in the same elevation are averaged. It can be said that it is low.
Then, as shown in FIG. 4, in the subsequent step S02, by comparing the average values of the room temperature for each elevation, is the variation in the temperature distribution in the room 2 within the allowable range while simplifying the arithmetic processing work? It is determined whether or not.

According to the indoor temperature control system 1B according to the second embodiment as described above, the indoor temperature control system 1A according to the first embodiment has the same amount of work and load as the indoor temperature control system 1A according to the first embodiment. The same effect can be exhibited.
Further, according to the indoor temperature control system 1B according to the second embodiment, the temperature control of the room 2 can be efficiently performed even when the room for temperature control is wide and a large number of temperature sensors are provided. .

In the flowchart of the work procedure using the indoor temperature control system 1B according to the second embodiment as shown in FIG. 4, the following steps may be incorporated in place of step S09.
That is, instead of step S09, a difference between two measurement values selected as desired from among the measurement values detected by a plurality of temperature sensors provided in each elevation in the room 2 is obtained, and the maximum value 2 is obtained. A step of extracting two measured values may be provided.
Then, after this process, in step S02 shown in FIG. 4, the difference between the two measurement values selected as desired is further selected from the set of two measurement values of each elevation extracted in the previous process. Then, the difference (arithmetic difference) is compared with the first set value set as desired, and when the value of the arithmetic difference exceeds the first set value, an operation signal is sent to the fan 5. A stop signal may be transmitted to the fan 5 when the arithmetic difference value is equal to or less than the first set value.
According to the indoor temperature control system 1B according to such a modification, the fan 5 can be operated so as to detect and correct the variation in the temperature distribution in the room 2 more sensitively.
However, in this case, since step S02 is substantially repeated twice after step S01, the load on the arithmetic processing unit 10 is slightly increased. However, the load on the arithmetic processing unit 10 is surely compared with a case where two desired measurement values are selected from a set of measurement values of all temperature sensors disposed in the room 2 and the difference is obtained. Can be reduced.

  As described above, the present invention maintains the temperature of the room containing the control equipment necessary for the operation of a thermal power plant, a hydroelectric power plant, or a nuclear power plant in an appropriate temperature range while reducing the variation in the temperature distribution at room temperature. In addition, the present invention relates to an indoor temperature control system capable of reducing power consumption at that time, and can be used in fields related to facilities and buildings such as other chemical plants, biological plants, and experimental plants.
