Description

  The present invention relates to an automatic set value relaxation support apparatus and method for supporting relaxation of a set value (set temperature) of a room temperature of a control target space.

  Conventionally, in an air conditioning control system, the indoor temperature of a control target space is measured as an actual temperature, and the ability of conditioned air to the control target space is controlled so that the actual temperature matches the set temperature. For example, as the capacity of the conditioned air to the control target space, the amount of cold / hot water to the air conditioner that supplies the conditioned air to the control target space (the valve opening degree of the cold / hot water valve) is controlled, or the conditioned air from the air conditioner Supply amount (the number of rotations of the air supply fan) is controlled.

  In this air conditioning control system, an air conditioning controller (monitoring device) that controls the ability of conditioned air to the control target space is provided with a set temperature display unit that displays a set temperature. The set temperature display unit includes a type that displays only the set temperature, a type that displays the set temperature and the room temperature (actual temperature) at the same time, and a type that displays the set temperature and the actual temperature by switching them.

  The set temperature displayed on the set temperature display section can be changed by a user operation. For example, when the amount of energy used seems to increase, the set temperature can be changed within a range that does not impair the comfort of the control target space, and the amount of energy used can be reduced. For example, if the cooling operation is in progress, the set temperature is changed (relaxed) higher, and if it is in the heating operation, the set temperature is changed lower (relaxation). The amount of energy used is reduced by changing the temperature in the energy saving direction (see, for example, Patent Document 1).

JP 2008-286445 A

  However, when only the set temperature is displayed on the set temperature display section, since the relationship between the set temperature and the actual temperature is not known, the relaxation of the set temperature by the user may be skipped. For example, when the set temperature after the change is lower than the actual temperature even though the set temperature is raised during the cooling operation, the actual temperature does not change and the set temperature is not substantially relaxed.

  When both the set temperature and the actual temperature can be displayed, the user needs to determine the set temperature after the relaxation by comparing the set temperature before the relaxation with the actual temperature, which is likely to be a burden on the user. For example, during cooling operation, when the set temperature before relaxation is 24 ° C. and the actual temperature is 26 ° C., in order to relax the actual temperature by 1 ° C., the set temperature is set to 27 ° C. instead of 25 ° C. There is a need. In this case, the user must determine the set temperature from the relationship with the current actual temperature.

  This problem is caused by the occurrence of “a mismatch unique to air conditioning (deviation between the set temperature and the actual temperature)” between the set temperature and the actual temperature. For example, in the case of temperature control of a manufacturing apparatus, an operator that instructs the temperature whether the output (operation amount MV) output from the controller to the heater is the upper limit (100%) or the lower limit (0%). Can be recognized. Moreover, also in the design of the manufacturing apparatus, the necessary temperature state can be realized in the range from the lower limit to the upper limit of the heater.

  On the other hand, with air-conditioning temperature control, not only residents but also building managers do not recognize whether the output from the controller has reached the upper limit or lower limit. Excessive air conditioning equipment that can cope with extremely hot and cold conditions is not adopted. Since the authority to instruct the temperature is given to those who do not recognize the mechanism of such design common sense and control logic (such as PID calculation) (residents, etc.), between the set temperature and the actual temperature Deviation occurs.

  The present invention was made in order to solve such a problem, and its purpose is to impose a burden on the user even if a deviation occurs between the set temperature and the actual temperature, An object of the present invention is to provide a set value automatic relaxation support apparatus and method capable of constantly relaxing a set temperature intended by a user.

  In order to achieve such an object, the present invention provides an actual temperature measuring means for measuring the indoor temperature of the control target space as an actual temperature, and a set temperature storage means for storing a set value of the indoor temperature of the control target space as a set temperature. Control means for controlling the capacity of the conditioned air to the control target space so that the actual temperature matches the set temperature, and in the state where the set temperature is on the increased energy side with respect to the actual temperature, When there is a setting change operation, there is provided a set temperature automatic relaxation support means that uses a value obtained by adding a deviation of the set temperature before and after the setting change operation in the energy saving direction to the actual temperature at that time to set the changed set temperature. To do.

According to the present invention, when there is a setting change operation to the energy saving side with respect to the set temperature in a state where the set temperature is on the energy increasing side, the deviation of the set temperature before and after the setting change operation is added to the actual temperature at that time. The value added in the energy saving direction is the set temperature after the change. For example, if there is a setting change operation from the user that raises the set temperature while the set temperature is lower than the actual temperature during the cooling operation, that is, if there is a setting change operation that increases the current set temperature tsp _now to tsp _up. The value obtained by adding the set temperature deviation Δt (Δt = tsp _up −tsp _now ) before and after the setting change operation to the actual temperature tpv at that time is set as the set temperature tsp after change (tsp = tpv + Δt). When the deviation Δt is given as a setting change operation from the user, the changed set temperature tsp (tsp = tpv + Δt) is obtained by adding the deviation Δt to the actual temperature tpv at that time.

  In the present invention, when there is a setting change operation to the energy saving side with respect to the set temperature in a state where the set temperature is higher than the actual temperature, the deviation of the set temperature before and after the setting change operation is saved to the actual temperature at that time. Although the value added to the direction is set as the set temperature after the change, it may be added as a condition whether or not the state where the control of the conditioned air capacity to the control target space has reached the limit has continued for a predetermined time or more. .

  For example, the amount of operation for an air conditioner that supplies conditioned air to the controlled space (such as the valve opening of the hot / cold water valve or the rotation speed of the air supply fan) Etc.) is added as a condition that the state where the limit has been reached has continued for a predetermined time or longer. In addition, a state in which the actual temperature does not change and a state in which the operation amount with respect to the air conditioner that supplies conditioned air to the control target space has reached the limit may be added as conditions. In this case, the predetermined time when the actual temperature does not change and the predetermined time when the operation amount with respect to the air conditioner reaches the limit may be the same time or different times.

  In addition, an effective / invalid setting means that enables selective setting of whether to enable or disable the operation of the set temperature automatic relaxation support means may be provided, and the user sets the current set temperature. It is also possible to provide a set temperature display means for displaying in a distinguishable manner whether the value is the determined value itself or the value determined by the set temperature automatic relaxation support means.

  It should be noted that the present invention can be implemented not as a set value automatic relaxation support apparatus but as a set value automatic change method. The invention according to claims 8 to 14 uses the invention according to the set value automatic relaxation support apparatus of claims 1 to 7 as a method.

  According to the present invention, when there is a setting change operation to the energy saving side with respect to the set temperature in a state where the set temperature is on the energy increasing side, the deviation of the set temperature before and after the setting change operation to the actual temperature at that time Since the value added in the energy saving direction is set as the set temperature after the change, even if there is a discrepancy between the set temperature and the actual temperature, the setting intended by the user is not imposed on the user. It becomes possible to always relax the temperature.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an instrumentation diagram showing a main part of an air conditioning control system using a set value automatic relaxation support apparatus according to the present invention.

  In FIG. 1, 1 is a control target space, 2 is an air conditioner (FCU) that supplies conditioned air to the control target space 1, 3 is a hot / cold water valve, 4 is a set value automatic relaxation support device according to the present invention. It is an air-conditioning controller provided as an embodiment.

  In this air conditioning control system, the air conditioner 2 includes a cold / hot water coil 2-1 and an air supply fan 2-2. The cold / hot water valve 3 is provided in the cold / hot water supply passage to the cold / hot water coil 2-1 of the air conditioner 2. In this example, the cold / hot water valve 3 is provided in the return pipe of the cold / hot water returned from the cold / hot water coil 2-1 of the air conditioner 2.

  The control target space 1 is provided with an indoor temperature sensor 5 that measures the indoor temperature of the control target space 1 as an actual temperature. The actual temperature tpv measured by the room temperature sensor 5 is sent to the air conditioning controller 4. In addition, the set value of the room temperature from the user is given to the air conditioning controller 4 as the set temperature tsp.

  The air conditioning controller 4 is realized by hardware including a processor and a storage device, and a program that realizes various functions in cooperation with these hardware. Have. Hereinafter, taking the case of cooling operation as an example, the set temperature automatic relaxation support function of the air conditioning controller 4 will be described.

[Embodiment 1: Case 1]
FIG. 2 is a time chart for explaining the case 1 of the first example (Embodiment 1) of the automatic set temperature relaxation support function of the air conditioning controller 4. The characteristic indicated by a solid line in the figure indicates a change in the set temperature tsp, and the characteristic indicated by a one-dot chain line indicates a change in the actual temperature tpv.

  In case 1 of the first embodiment, the actual temperature tpv is initially higher than the set temperature tsp (20 ° C.) (point t0 shown in FIG. 2). From this state, the actual temperature tpv is set to the set temperature tsp (20 The actual temperature tpv stops changing before reaching the set temperature tsp (20 ° C.) (point t1 shown in FIG. 2).

  The stop state of the change in the actual temperature tpv indicates that the valve opening degree θ of the cold / hot water valve 3 reaches 100% and the state of 100% of the valve opening degree θ continues. That is, the control of the cooling capacity of the conditioned air from the air conditioner 2 to the control target space 1 has reached the limit (100% operation (full operation)), and this 100% operation state continues.

  In such a state, the user is manually changing the set temperature tsp from 20 ° C. to 22 ° C. (point t2 shown in FIG. 2). That is, while the actual temperature tpv is higher than the set temperature tsp (20 ° C.), the set temperature tsp is to be changed from 20 ° C. to 22 ° C. by manual operation.

In this case, the air conditioning controller 4 has the set temperature tsp on the energy increasing side with respect to the actual temperature tpv, and there is a divergence between the set temperature tsp and the actual temperature tpv. In this state, the energy saving side with respect to the set temperature tsp It is determined that there has been a setting change operation from the user, and a value obtained by adding the deviation Δt of the set temperature tsp before and after the setting change operation in the energy saving direction to the actual temperature tpv at that time is set as the changed set temperature tsp.

In this example, the current set temperature (the set temperature before the change operation) is tsp _now (20 ° C.), the set temperature after the setting change operation from the user is tsp _up (22 ° C.), and the actual temperature tpv ( A value obtained by adding a deviation Δt of the set temperature before and after the setting change operation to 24 ° C. is set as a changed set temperature tsp (tsp = tpv + Δt). In this case, Δt = tsp _up −tsp _now = 22 ° C.−20 ° C. = 2 ° C. Therefore, the set temperature tsp after the change is set to tsp = tpv + Δt = 24 ° C. + 2 ° C. = 26 ° C.

  Thus, when the user manually changes the set temperature tsp from 20 ° C. to 22 ° C., the set temperature tsp is automatically changed to 26 ° C. instead of 22 ° C. (point t2 shown in FIG. 2).

  In this case, since the changed set temperature tsp (26 ° C.) is higher than the actual temperature tpv (24 ° C.), the actual temperature tpv changes so as to follow the set temperature tsp (26 ° C.), and eventually the actual temperature tpv. Becomes equal to the set temperature tsp (26 ° C.) (point t3 shown in FIG. 2), which is the temperature intended by the user.

[Embodiment 1: Case 2]
FIG. 3 is a time chart for explaining the case 2 of the first example (Embodiment 1) of the automatic set temperature relaxation support function of the air conditioning controller 4. The characteristic indicated by a solid line in the figure indicates a change in the set temperature tsp, and the characteristic indicated by a one-dot chain line indicates a change in the actual temperature tpv.

  In case 2 of the first embodiment, the user is manually changing the set temperature tsp from 20 ° C. to 22 ° C. while the actual temperature tpv is changing to follow the set temperature tsp (20 ° C.). (T2 shown in FIG. 3). That is, while the actual temperature tpv is higher than the set temperature tsp (20 ° C.), the set temperature tsp is to be changed from 20 ° C. to 22 ° C. by manual operation.

In this case, the air conditioning controller 4 has the set temperature tsp on the energy increasing side with respect to the actual temperature tpv, and there is a divergence between the set temperature tsp and the actual temperature tpv. In this state, the energy saving side with respect to the set temperature tsp It is determined that there has been a setting change operation from the user, and a value obtained by adding the deviation Δt of the set temperature tsp before and after the setting change operation in the energy saving direction to the actual temperature tpv at that time is set as the changed set temperature tsp.

In this example, the current set temperature (the set temperature before the change operation) is tsp _now (20 ° C.), the set temperature after the setting change operation from the user is tsp _up (22 ° C.), and the actual temperature tpv ( The value obtained by adding the set temperature deviation Δt (2 ° C.) before and after the setting change operation to the set temperature tsp (tsp = tpv + Δt = 26 ° C.) after change.

  Thus, when the user manually changes the set temperature tsp from 20 ° C. to 22 ° C., the set temperature tsp is automatically changed to 26 ° C. instead of 22 ° C. (point t2 shown in FIG. 3).

  In this case, since the changed set temperature tsp (26 ° C.) is higher than the actual temperature tpv (24 ° C.), the actual temperature tpv changes so as to follow the set temperature tsp (26 ° C.), and eventually the actual temperature tpv. Becomes equal to the set temperature tsp (26 ° C.) (point t3 shown in FIG. 3), which is the temperature intended by the user.

  In this way, in this embodiment, even if a deviation occurs between the set temperature tsp and the actual temperature tpv, the set temperature intended by the user is always relaxed without imposing a burden on the user. Will be able to.

  FIG. 4 shows a functional block diagram of the main part of the air conditioning controller 4 in the first embodiment. The air conditioning controller 4 includes a set temperature storage unit 41 that stores the set temperature tsp, a control unit 42 that controls the valve opening θ of the cold / hot water valve 3, and a relaxation of the set temperature tsp stored in the set temperature storage unit 41. A set temperature automatic relaxation support unit 43 (43A) that supports the actual temperature tpv measured by the room temperature sensor 5 and a set temperature display unit 44 that displays the set temperature tsp stored in the set temperature storage unit 41; An enable / disable setting unit 45 is provided for selectively setting whether to enable or disable the operation of the set temperature automatic relaxation support unit 43A according to a user operation. The room temperature sensor 5 is attached to the air conditioning controller 4 as actual temperature measuring means.

  In the air conditioning controller 4, the control unit 42 receives the actual temperature tpv measured by the room temperature sensor 5 and the set temperature tsp stored in the set temperature storage unit 41 and matches the actual temperature tpv with the set temperature tsp. Thus, the valve opening degree θ of the cold / hot water valve 3 is controlled.

The set temperature automatic relaxation support unit 43A performs the actual temperature tpv measured by the room temperature sensor 5, the set temperature tsp (current set temperature tsp _now ) stored in the set temperature storage unit 41, and the setting change operation from the user. and a set temperature tsp _{Stay up-and} input, for example, during cooling operation, in the state of actual temperature tpv> set temperature tsp, if there is a setting change operation from the user in the direction of raising the set temperature tsp, actual temperature at that time A value obtained by adding a difference Δt (Δt = tsp _up −tsp _now ) of the set temperature before and after the setting change operation to tpv is obtained as the set temperature tsp after change (tsp = tpv + Δt), and is stored in the set temperature storage unit 41. The set temperature tsp is automatically changed.

  When the set temperature tsp is displayed, the set temperature display unit 44 displays whether the set temperature is a value set by the user or a value changed by the set temperature automatic relaxation support unit 43A. The valid / invalid setting unit 45 invalidates or validates the operation of the set temperature automatic relaxation support unit 43A according to a user operation (selection operation from the user).

[Embodiment 2: Case 1]
FIG. 5 is a time chart for explaining the case 1 of the second example (Embodiment 2) of the preset temperature automatic relaxation support function of the air conditioning controller 4. The characteristic indicated by a solid line in the figure indicates a change in the set temperature tsp, and the characteristic indicated by a one-dot chain line indicates a change in the actual temperature tpv.

  In case 1 of the second embodiment, the actual temperature tpv is initially higher than the set temperature tsp (20 ° C.) (point t0 shown in FIG. 5). From this state, the actual temperature tpv is set to the set temperature tsp (20 The actual temperature tpv stops changing before reaching the set temperature tsp (20 ° C.) (point t1 shown in FIG. 5). The state where the actual temperature tpv does not change continues for a predetermined time T1 (in this example, T1 = 10 minutes) or more.

  In such a state, the user intends to manually change the set temperature tsp from 20 ° C. to 22 ° C. (point t3 shown in FIG. 5). That is, when the actual temperature tpv is higher than the set temperature tsp (20 ° C.) and the actual temperature tpv does not change for a predetermined time T1 or longer, the set temperature tsp is changed from 20 ° C. to 22 ° C. by manual operation. Yes.

In this case, the air conditioning controller 4 has a set temperature tsp on the energy increasing side with respect to the actual temperature tpv, and there is a divergence between the set temperature tsp and the actual temperature tpv when the air conditioner 2 is in full operation. In this state, it is determined that there has been a setting change operation from the user toward the energy saving side with respect to the set temperature tsp, and after changing the value obtained by adding the deviation Δt of the set temperature tsp before and after the setting change operation in the energy saving direction to the actual temperature tpv at that time Is set temperature tsp.

In this example, the current set temperature (the set temperature before the change operation) is tsp _now (20 ° C.), the set temperature after the setting change operation from the user is tsp _up (22 ° C.), and the actual temperature tpv ( The value obtained by adding the set temperature deviation Δt (2 ° C.) before and after the setting change operation to the set temperature tsp (tsp = tpv + Δt = 26 ° C.) after change.

  Thus, if the user manually changes the set temperature tsp from 20 ° C. to 22 ° C. on the condition that the actual temperature tpv does not change for a predetermined time T1 or longer, the set temperature tsp is not 22 ° C. but 26 The temperature is automatically changed to ° C. (t3 point shown in FIG. 5).

  In this case, since the changed set temperature tsp (26 ° C.) is higher than the actual temperature tpv (24 ° C.), the actual temperature tpv changes so as to follow the set temperature tsp (26 ° C.), and eventually the actual temperature tpv. Becomes equal to the set temperature tsp (26 ° C.) (point t4 shown in FIG. 5), which is the temperature intended by the user.

[Embodiment 2: Case 2]
FIG. 6 is a time chart for explaining Case 2 of the second example (Embodiment 2) of the preset temperature automatic relaxation support function of the air conditioning controller 4. The characteristic indicated by a solid line in the figure indicates a change in the set temperature tsp, and the characteristic indicated by a one-dot chain line indicates a change in the actual temperature tpv.

  In case 2 of the second embodiment, the user is manually changing the set temperature tsp from 20 ° C. to 22 ° C. in a state where the actual temperature tpv does not change for a predetermined time T1 or longer (FIG. 6). T2 point).

  In this case, the air conditioning controller 4 does not determine that there is a deviation between the set temperature tsp and the actual temperature tpv when the air conditioner 2 is in full operation, and does not automatically change the set temperature tsp. . Thereby, the manual change of the set temperature tsp by the user is permitted, and the set temperature tsp is changed from 20 ° C. to 22 ° C.

FIG. 7 shows a functional block diagram of the main part of the air conditioning controller 4 in the second embodiment. In the air conditioning controller 4, the set temperature automatic relaxation support unit 43 (43 </ b> B) includes the actual temperature tpv measured by the room temperature sensor 5 and the set temperature tsp (current set temperature tsp _now ) stored in the set temperature storage unit 41. ) And the set temperature tsp _up after the setting change operation from the user, for example, during the cooling operation, the state where the actual temperature tpv> the set temperature tsp and the actual temperature tpv does not change continues for a predetermined time T1 or more. In the state, when there is a setting change operation from the user in the direction of increasing the set temperature tsp, the deviation Δt (Δt = tsp _up −tsp _now ) of the set temperature before and after the setting change operation is added to the actual temperature tpv at that time Is obtained as a set temperature tsp after change (tsp = tpv + Δt), and the set temperature tsp stored in the set temperature storage unit 41 is automatically changed.

From this state, the actual temperature tpv becomes the set temperature. Since it changes to follow tsp (20 ° C.) and the valve opening θ of the cold / hot water valve 3 has reached 100% along with this change (point t1 shown in FIG. 8B), the set temperature tsp (20 ° C.) ) Until the actual temperature tpv stops changing (point t2 shown in FIG. 8A). The state where the valve opening θ reaches 100% continues for a predetermined time T2 (T2 = 10 minutes in this example).

That is, in a state where the actual temperature tpv is higher than the set temperature tsp (20 ° C.) and the valve opening θ reaches 100% for a predetermined time T2 or longer, the set temperature tsp is manually changed from 20 ° C. to 22 ° C. Trying to change.

In this case, the air conditioning controller 4 has a set temperature tsp on the energy increasing side with respect to the actual temperature tpv, and there is a divergence between the set temperature tsp and the actual temperature tpv when the air conditioner 2 is in full operation. In this state, it is determined that there has been a setting change operation from the user toward the energy saving side with respect to the set temperature tsp, and after changing the value obtained by adding the deviation Δt of the set temperature tsp before and after the setting change operation in the energy saving direction to the actual temperature tpv at that time Is set temperature tsp.

In this example, the current set temperature (the set temperature before the change operation) is tsp _now (20 ° C.), the set temperature after the setting change operation from the user is tsp _up (22 ° C.), and the actual temperature tpv ( The value obtained by adding the set temperature deviation Δt (2 ° C.) before and after the setting change operation to the set temperature tsp (tsp = tpv + Δt = 26 ° C.) after change.

  Thus, if the user manually changes the set temperature tsp from 20 ° C. to 22 ° C. on the condition that the valve opening θ reaches 100% for a predetermined time T2 or longer, the set temperature tsp becomes 22 ° C. Instead, the temperature is automatically changed to 26 ° C. (t4 point shown in FIG. 8A).

From this state, the actual temperature tpv becomes the set temperature. Since it changes so as to follow tsp (20 ° C.), and the valve opening θ of the cold / hot water valve 3 has reached 100% (t1 point shown in FIG. 11B), the set temperature tsp (20 ° C.) ) Until the actual temperature tpv stops changing (point t2 shown in FIG. 11A).

  In such a state, the user is manually changing the set temperature tsp from 20 ° C. to 22 ° C. (point t5 shown in FIG. 11A). That is, the state where the actual temperature tpv is higher than the set temperature tsp (20 ° C.) and the actual temperature tpv does not change continues for a predetermined time T1 or more, and the state where the valve opening θ reaches 100% is the predetermined time T2. In the state continued as described above, the set temperature tsp is to be changed from 20 ° C. to 22 ° C. by manual operation.

In this case, the air conditioning controller 4 has a set temperature tsp on the energy increasing side with respect to the actual temperature tpv, and there is a divergence between the set temperature tsp and the actual temperature tpv when the air conditioner 2 is in full operation. In this state, it is determined that there has been a setting change operation from the user toward the energy saving side with respect to the set temperature tsp, and after changing the value obtained by adding the deviation Δt of the set temperature tsp before and after the setting change operation in the energy saving direction to the actual temperature tpv at that time Is set temperature tsp.

In this example, the current set temperature (the set temperature before the change operation) is tsp _now (20 ° C.), the set temperature after the setting change operation from the user is tsp _up (22 ° C.), and the actual temperature tpv ( The value obtained by adding the set temperature deviation Δt (2 ° C.) before and after the setting change operation to the set temperature tsp (tsp = tpv + Δt = 26 ° C.) after change.

  As a result, the user sets the set temperature tsp on the condition that the state in which the actual temperature tpv does not change continues for the predetermined time T1 or longer and the state in which the valve opening θ reaches 100% continues for the predetermined time T2 or longer. When the temperature is manually changed from 20 ° C. to 22 ° C., the set temperature tsp is automatically changed to 26 ° C. instead of 22 ° C. (point t5 shown in FIG. 11A).

  In this case, since the changed set temperature tsp (26 ° C.) is higher than the actual temperature tpv (24 ° C.), the actual temperature tpv changes so as to follow the set temperature tsp (26 ° C.), and eventually the actual temperature tpv. Becomes equal to the set temperature tsp (26 ° C.) (point t6 shown in FIG. 11A), which is the temperature intended by the user.

[Embodiment 4: Case 2]
FIG. 12 is a time chart for explaining the case 2 of the fourth example (Embodiment 4) of the preset temperature automatic relaxation support function of the air conditioning controller 4. The characteristic indicated by the solid line in FIG. 12A indicates a change in the set temperature tsp, and the characteristic indicated by the alternate long and short dash line indicates a change in the actual temperature tpv. FIG. 12B shows a change in the valve opening degree θ of the cold / hot water valve 3.

  In case 2 of the fourth embodiment, the state in which the actual temperature tpv does not change does not continue for a predetermined time T1 or longer, and the state in which the valve opening θ reaches 100% does not continue for the predetermined time T2 or longer. In this state, the user is manually changing the set temperature tsp from 20 ° C. to 22 ° C. (point t3 shown in FIG. 12A).

  In this case, the air conditioning controller 4 does not determine that there is a deviation between the set temperature tsp and the actual temperature tpv when the air conditioner 2 is in full operation, and does not automatically change the set temperature tsp. . Thereby, the manual change of the set temperature tsp by the user is permitted, and the set temperature tsp is changed from 20 ° C. to 22 ° C.

FIG. 13 shows a functional block diagram of a main part of the air conditioning controller 4 in the fourth embodiment. In the air conditioning controller 4, the set temperature automatic relaxation support unit 43 (43 </ b> D) includes the actual temperature tpv measured by the room temperature sensor 5 and the set temperature tsp (current set temperature tsp _now ) stored in the set temperature storage unit 41. ) And the set temperature tsp _up after the setting change operation by the user and the valve opening degree θ to the cold / hot water valve 3 are input. For example, during the cooling operation, the actual temperature tpv is set in the state of the actual temperature tpv> the set temperature tsp. There was a setting change operation from the user in the direction of increasing the set temperature tsp in a state in which the state did not change continued for the predetermined time T1 or longer and the state in which the valve opening degree θ reached 100% continued for the predetermined time T2 or longer. If the set temperature tsp (tsp = tpv + Δt after the change the value obtained by adding the actual temperature tpv the setting change operation of the front and rear set temperature deviation _{Δt (Δt = tsp up -tsp now} ) at that time As determined, automatically changes the set temperature tsp stored in the setting temperature storage unit 41.

In the first to fourth embodiments described above, the set temperature tsp _up after the setting change operation from the user is given to the set temperature automatic relaxation support unit 43 (43A to 43D). A deviation Δt may be given as an operation. In this case, the set temperature automatic relaxation support unit 43 obtains the changed set temperature tsp (tsp = tpv + Δt) by adding the given deviation Δt to the actual temperature tpv at that time.

  In Embodiments 2 and 4 described above, the state where the actual temperature tpv does not change may be determined from the actual temperature tpv itself, or may be determined from the deviation between the actual temperature tpv and the set temperature tsp. May be.

  Moreover, in Embodiment 4 mentioned above, although predetermined time T1, T2 was made into the same time, it is good also as a different time.

  Further, when the system configuration is such that the rotation speed of the air supply fan 2-2 is controlled by the air conditioning controller 4 (see FIG. 14), the rotation to the air supply fan 2-2 in the third and fourth embodiments described above. It may be determined from the number adjustment output (fan INV output) whether or not the control of the cooling capacity of the conditioned air to the control target space 1 has reached its limit. In this case, the set temperature tsp at the time of user operation is automatically changed on the condition that the state in which the fan INV output has reached 100% has continued for a predetermined time T2 or more.

Moreover, although Embodiment 1-4 mentioned above demonstrated taking the cooling operation as an example, the same operation | movement is performed also in heating operation. For example, in the first embodiment, during the heating operation, in the state of actual temperature tpv <set temperature tsp, if there is a setting change operation from the user in the direction of lowering the set temperature tsp, air conditioning controller 4, the actual time that A value obtained by subtracting the deviation Δt of the set temperature tsp before and after the setting change operation from the temperature tpv (a value obtained by adding the deviation Δt in the energy saving direction) is set as the changed set temperature tsp.
