TECHNICAL FIELD OF THE INVENTION
The present invention relates to an air conditioning temperature control device for controlling an air conditioning temperature.
[0002]
[Prior art]
Conventionally, in office buildings, etc., a method of controlling the air-conditioning temperature based on the air-conditioning set temperature set by a temperature setting device installed in each room, and a central monitoring device that monitors and controls the facilities of the entire office building A method of controlling the air conditioning temperature based on the set air conditioning temperature is adopted. These air-conditioning temperature controls control the air-conditioning temperature based on the standard set temperatures for cooling in summer and heating in winter, respectively, and people in office buildings feel the air-conditioning temperature extremely unpleasant. Only when this occurs, the standard set temperature may be changed exceptionally, but in general, the air conditioning temperature is controlled based on the standard set temperature in each of the summer and winter. The standard set temperature is generally 26 ° C. for cooling and 24 ° C. for heating in many cases.
[0003]
[Problems to be solved by the invention]
According to the above-mentioned conventional air-conditioning temperature control means, the air-conditioning set temperature during cooling and during heating often remains set to a constant value in each of the summer and winter periods. In this case, since the sensible temperature of a person in each room changes due to changes in the outside air temperature, humidity, and solar radiation, the user feels "cold" or "hot" and cannot obtain a comfortable air-conditioning environment. If the air-conditioning set temperature is set to be the optimum air-conditioning environment at the time of the highest outside temperature in summer or at the lowest outside temperature in winter, excessive air-conditioning will be performed and energy will be wasted. Also.
[0004]
Therefore, an object of the present invention is to provide an air-conditioning temperature control device that can realize energy saving and can provide a comfortable air-conditioning environment to a person in an air-conditioning area.
[0005]
[Means for Solving the Problems]
The above problem can be solved by the air-conditioning temperature control device described in the claims.
[0006]
According to the air conditioning temperature control device of the first aspect, when a person in the air conditioning area does not input the bodily sensation information, for example, while operating in the cooling mode, the air conditioning set temperature is gradually increased, and the operation in the heating mode is performed. Then, since the air-conditioning set temperature is gradually lowered, energy saving can be effectively realized. In addition, when a person in the air conditioning area inputs the sensation information, the respective sensation information is totaled, and the air conditioning set temperature of the air conditioning area is changed based on the totaling result. An air conditioning environment can be provided.
[0007]
According to the air-conditioning temperature control device of the second aspect, when a person in the air-conditioning area does not input the bodily sensation information, energy saving can be effectively realized similarly to the air-conditioning temperature control device of the first aspect. Also, when each person in the air conditioning area inputs the bodily sensation information, the respective bodily sensation information is totaled, and the air conditioning set temperature of the air conditioned area is calculated based on the number of persons in the air conditioned area and the totaling result of the bodily sensation information. Therefore, a comfortable air-conditioning environment can be given to a person in the air-conditioning area.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the present invention will be described.

[0009]
The air-conditioning set temperature control section 3 is provided with a computer (not shown) at a central portion. The computer of the air-conditioning set temperature control unit 3 occupies the occupant ID signal output from the occupant recognition device 4 (assigns an identification number (ID) to each occupant in advance), The air-conditioning set temperature commanded to the air conditioner 2 is calculated based on the sensation information such as "hot", "cold", and "neither" input to 5; Outputs the corresponding set temperature signal. The specific air-conditioning temperature control by the computer of the air-conditioning set temperature control unit 3 will be described later with reference to the flowcharts of FIGS.
[0010]
The occupant recognition device 4 that detects the occupants of each room and recognizes the number of occupants is an image processing system that processes images captured by a video camera or the like and recognizes the occupants, or each person. An IC card system or the like that reads the IC card carried by the user when entering the room and recognizes the number of occupants is used.
[0011]
As the terminal 5 for inputting the bodily sensation information, a commercially available personal computer used by each occupant for business or a terminal specially manufactured is used. The sensation information such as “hot”, “cold”, and “neither” input from a personal computer or a specially manufactured terminal is converted into a wireless signal and transmitted to the air-conditioning set temperature control unit 3. You may do so. In that case, wiring between each terminal 5 and the air-conditioning set temperature control unit 3 becomes unnecessary.
[0012]
The air conditioner 2 may be a commercially available type capable of inputting the set temperature signal output from the air conditioning set temperature control unit 3 or a dedicated type incorporating the air conditioning set temperature control unit 3 integrally. . Note that the air conditioner 2 outputs a “running signal” to the air conditioning set temperature control unit 3 in a state where the operation has been started. The “running signal” is obtained by modifying the electronic circuit of the air conditioner 2 so that the signal can be output, or by obtaining the “running signal” by measuring the current or power of the air conditioner 2. You may. When the air conditioner 2 is newly designed and manufactured, the specifications are set so that the "during operation" signal can be output.
[0013]
Next, the control operation of the air conditioning temperature control device 1 will be described.
FIG. 2 is a flowchart showing a control operation of the air-conditioning temperature control device 1 when a commercially available personal computer used by each occupant of each room of the office building for business is used as the terminal 5.
[0014]
As shown in step S1 of the flowchart of FIG. 2, when the operation of the air conditioner 2 is started and the above-mentioned "operating signal" is output from the air conditioner 2 to the air conditioning set temperature control unit 3, the air conditioning set temperature control unit The computer No. 3 outputs a set temperature signal corresponding to the initial set temperature T0 (for example, 26 ° C.) to the air conditioner 2 as shown in step S2.
[0015]
When the air conditioner 2 is operating in the cooling mode, for example, the computer of the air-conditioning set temperature control unit 3 starts measuring the time (t2) as shown in step S3, and in step S4, the computer measures t2 minutes (for example, 30 minutes). Each time it is determined that the predetermined set time has elapsed, a set temperature signal obtained by adding T1 ° C. (for example, 0.5 ° C.) to the current set temperature T is output to the air conditioner 2 as shown in step S5. Is gradually increased.
Also, when the air conditioner 2 is operating in the heating mode, measurement of the time (t2) is started as shown in step S3, and in step S4, it is determined that t2 minutes (for example, 30 minutes) have elapsed. Next, as shown in step S5, a set temperature signal obtained by subtracting T1 ° C. (for example, 0.5 ° C.) from the current set temperature T is output to the air conditioner 2, and control is performed to gradually lower the air conditioning set temperature. .
[0016]
If the air-conditioning set temperature is gradually changed as shown in steps S3, S4, and S5, the indoor temperature gradually changes in a direction in which the energy consumption decreases, so that energy saving operation can be performed. In the process, when a certain occupant feels "hot" or "cold" and inputs the sensation information of "hot" or "cold" to the personal computer, the computer of the air-conditioning set temperature control unit 3 proceeds to step S6. It is determined that there is a temperature change request, and as shown in step S7, a question, "whether it is hot, cold, or neither," is sent to all the personal computers in the room at once, and all the questions are asked. Display on the screen of the personal computer.
[0017]
When the question information is displayed on the screen of each personal computer, each occupant answers the question from the personal computer within t1 minutes (for example, 5 minutes). When each piece of response information is input from the personal computer in the room to the computer of the air-conditioning set temperature control unit 3, the computer can count the number of occupants in the room. That is, in this case, all the personal computers in the same room serve as both the occupant recognition device 4 and the terminal 5 described above.
[0018]
In step S7, the computer of the air-conditioning set temperature controller 3 broadcasts a question, "whether it is hot, cold, or neither" to all the personal computers at once, as shown in step S8. When the measurement of (t1) is started, and it is determined in step S9 that t1 minutes have elapsed, as shown in step S10, the reception of the answer to the same question is terminated, and each answer is totaled, and a majority decision is made. Make a calculation.
[0019]
In step S11, the computer of the air-conditioning set temperature control unit 3 determines whether or not the sensation information of "hot" is a majority, and if it is a majority, in step S12, the current set temperature T is changed to T2 ° C. (for example, A set temperature signal corresponding to the temperature obtained by subtracting (2 ° C.) is sent to the air conditioner 2 to greatly reduce the set temperature of the air conditioner.
[0020]
On the other hand, in step S11, when it is determined that the bodily sensation information “hot” is not a majority, in step S13, it is determined whether the bodily sensation information “cold” is a majority, and when it is a majority, in step S14, A set temperature signal corresponding to a temperature obtained by adding T2 ° C. (for example, 2 ° C.) to the current set temperature T is sent to the air conditioner 2 to greatly increase the air conditioner set temperature. In step S13, if the sensation information of "cold" is not a majority, that is, if neither "hot" nor "cold" is a majority, in step S15, the sensation information data calculated by the majority decision is canceled, and then in step S3 , S4 and S5, and repeat steps S6 to S15.
[0021]
The computer of the air-conditioning setting temperature control unit 3 determines that the majority of the people who answered "hot" or "cold" change the air-conditioning setting temperature as shown in steps S12 and S14, and then the next air-conditioning setting Do not accept temperature changes. Therefore, the measurement of the time (t3) is started as shown in step S16, and when it is determined in step S17 that t3 minutes (for example, 30 minutes) have elapsed after the previous air conditioning set temperature change, the sensation information data of the majority calculation is obtained. , And energy saving is realized by driving in steps S3, S4, and S5, and by repeating steps S6 to S17, a comfortable air-conditioning environment can be given to many people.
When the computer of the air conditioning set temperature control unit 3 sends a set temperature signal to the air conditioner 2 to change the air conditioning set temperature, the air conditioner 2 responds to the change of the air conditioning set temperature by changing the air flow rate and the flow rate of the hot and cold water. And so on.
[0022]
FIG. 3 shows a case where the above-described image processing device or IC card system is used as the occupant recognition device 4 for recognizing each occupant of each room, and a dedicated terminal is used as the terminal 5. 4 is a flowchart illustrating a control operation of the air-conditioning temperature control device 1.
[0023]
As shown in step S1 of the flowchart of FIG. 3, when the operation of the air conditioner 2 is started and the above-mentioned “operating signal” is output from the air conditioner 2 to the air conditioning set temperature control unit 3, the air conditioning set temperature control unit The computer No. 3 outputs a set temperature signal corresponding to the initial set temperature T0 (for example, 26 ° C.) to the air conditioner 2 as shown in step S2.
[0024]
When the air conditioner 2 is operating in, for example, the cooling mode, the computer of the air-conditioning set temperature control unit 3 starts measuring the time (t2) as shown in step S3, and in step S4, the computer measures t2 minutes (for example, 30 minutes). ) Is output to the air conditioner 2 every time it is determined that the current set temperature T plus T1 ° C. (for example, 0.5 ° C.) is added to the air conditioner 2 as shown in step S5, and the air conditioning set temperature is gradually increased. Control to increase the value. Also, when the air conditioner 2 is operating in the heating mode, measurement of the time (t2) is started as shown in step S3, and in step S4, it is determined that t2 minutes (for example, 30 minutes) have elapsed. Next, as shown in step S5, a set temperature signal obtained by subtracting T1 ° C. (for example, 0.5 ° C.) from the current set temperature T is output to the air conditioner 2, and control is performed to gradually lower the air conditioning set temperature. .
[0025]
If the air-conditioning set temperature is gradually changed as shown in steps S3, S4, and S5, the indoor temperature gradually changes in a direction in which the energy consumption decreases, so that energy saving operation can be performed. In the process, if a certain occupant feels “hot” or “cold”, he or she inputs the sensation information “hot” or “cold” to the terminal device 5 and requests a temperature change.
The computer of the air-conditioning set temperature controller 3 starts measuring the time (t1) in step S6, and determines in step S7 whether the time t1 has elapsed. If the time t1 has not elapsed, it is determined in step S8 whether or not there is a temperature change request. When it is determined that there is no request for temperature change, the process returns to step S7. On the other hand, when it is determined that there is a request for temperature change, as shown in step S9, the identification number ID of the person who made the request for temperature change and "hot". Alternatively, the data of "cold" is stored, and thereafter, the process returns to step S7.
[0026]
If it is determined in step S7 that the time t1 has elapsed, it is determined in step S10 whether the number of temperature change requests is zero. If the number of persons requesting the temperature change is zero, the process returns to step S6, while if it is determined that there is a person requesting the temperature change, the procedure proceeds to step S11.
[0027]
In step S11, the computer of the air-conditioning set temperature control unit 3 counts the number of occupants based on the current occupant ID signal recognized by the occupant recognition device 4 described above. Hot and cold ”and calculate the majority.
[0028]
In step S13, the computer of the air-conditioning set temperature control unit 3 determines whether or not the sensation information of "hot" is a majority, and if it is a majority, in step S14, the current set temperature T is T2 ° C (for example, A set temperature signal corresponding to the temperature obtained by subtracting (2 ° C.) is sent to the air conditioner 2 to greatly reduce the set temperature of the air conditioner.
[0029]
On the other hand, if it is determined in step S13 that the sensation information of “hot” is not the majority, it is determined in step S15 whether the sensation information of “cold” is the majority, and if it is the majority, in step S16, A set temperature signal corresponding to a temperature obtained by adding T2 ° C. (for example, 2 ° C.) to the current set temperature T is sent to the air conditioner 2 to greatly increase the air conditioner set temperature. In step S15, the bodily sensation information of "cold" is not a majority, that is, neither "hot" nor "cold" is a majority, in step S17, the bodily sensation information of the majority calculation is canceled, and in step S3, The operations in S4 and S5 are performed, and steps S6 to S17 are repeated.
[0030]
As described above, the air-conditioning temperature control device 1 realizes energy saving by operating steps S3, S4, and S5, and can provide a comfortable air-conditioning environment to many people by repeating steps S6 to S17. .
[0031]
In the control operation of the air-conditioning temperature control device 1 as shown in FIGS. 2 and 3, the air-conditioning set temperature is changed by a majority decision calculation based on the number of occupants and the bodily sensation information. Regardless of the number of persons, it is possible to provide a comfortable air-conditioning environment to a large number of persons even when the air-conditioning set temperature is changed based on only the sensation information input by the occupants. For example, if more sensation information is input to the occupants within a certain period of time, it is determined that the change request is high regardless of the number of occupants, and the air-conditioning set temperature is changed.
[0032]
