Fig. 6 is a schematic diagram showing the input/output relationship with respect to control of the air conditioner according to embodiment 1.

As described above, the air conditioner according to embodiment 1 includes the indoor control device 11 and the outdoor control device 25. The indoor control device 11 and the outdoor control device 25 are each configured by, for example, dedicated hardware or a CPU (Central Processing Unit, also referred to as a Central Processing Unit, a Processing device, an arithmetic device, a microprocessor, or a processor) that executes a program stored in a memory. The indoor control device 11 mainly performs processing related to the indoor operation of the indoor unit 100. The outdoor control device 25 mainly performs processing related to the outdoor side operation of the outdoor unit 200. The indoor control device 11 and the outdoor control device 25 communicate with each other, and exchange signals including data related to control. Hereinafter, the indoor control device 11 and the outdoor control device 25 are collectively referred to as a control device.

The outdoor control device 25 includes an outdoor input unit 41, an outdoor control unit 42, and an outdoor output unit 43. The outdoor input unit 41 transmits data included in a signal transmitted from a device or the like outside the outdoor control device 25 to the outdoor control unit 42. As data transmitted from the outdoor input unit 41 to the outdoor control unit 42, for example, there is data of the outside air temperature related to the detection by the outside air temperature sensor 26. The outdoor output unit 43 processes data related to the control instruction from the outdoor control unit 42 and transmits a signal to the corresponding device. The devices that receive instructions via the outdoor output unit 43 include the compressor 20, the outdoor fan 21, the flow path switching device 23, and the throttle device 24.

The indoor control device 11 includes an indoor input unit 31, an indoor control unit 37, and an indoor output unit 38. The indoor input unit 31 transmits data included in a signal transmitted from a device or the like outside the indoor control device 11 to the indoor control unit 37. The data transmitted from the indoor input unit 31 to the indoor control unit 37 includes, for example, data of an operation mode instructed by the user to the remote controller 16, operation contents such as a set temperature, and data related to various sensors. The data relating to the various sensors includes data relating to the indoor heat exchanger temperature relating to detection by the indoor heat exchanger temperature sensor 13, data relating to the room temperature relating to detection by the indoor temperature sensor 14, data relating to the humidity of the air-conditioned space relating to detection by the indoor humidity sensor 15, data relating to the state of the air-conditioned space relating to detection by the indoor state detection sensor 8, and the like. The indoor output unit 38 processes data related to a control instruction from the indoor control unit 37 and transmits a signal to a corresponding device.

The indoor control unit 37 controls the devices in the indoor unit 100, and controls the entire indoor unit 100. The indoor control unit 37 includes a calculation processing unit 32, an air conditioning load determination unit 33, a thermal sensation determination unit 34, a determination processing unit 35, and a storage unit 36. As will be described later, the arithmetic processing unit 32 performs arithmetic processing of values used in the determination processing of the determination processing unit 35, such as calculation of a temperature difference. The air conditioning load determination unit 33 performs determination regarding the air conditioning load in the air-conditioned space. The air conditioning load determination unit 33 obtains a trend of the air conditioning load (hereinafter, referred to as an air conditioning load trend) in the future. Here, the air conditioning load tendency means a slope indicating whether the air conditioning load will increase, decrease, or remain unchanged in the future. The air conditioning load tendency is obtained based on the current and past indoor heat exchanger temperatures, the outside air temperature, the room temperature of the air-conditioned space, the air conditioning capacity, and the amount of solar radiation passing through the window of the air-conditioned space. The air conditioning capacity is determined based on the rotation speed of the compressor 20, the rotation speeds of the indoor fans 6a and 6b, the rotation speed of the outdoor fan 21, and the indoor heat exchanger temperature. The amount of solar radiation passing through the window of the air-conditioned space is detected by the indoor condition detection sensor 8 of the sensor unit 7. If the numerical value of the air conditioning load tendency is positive, the air conditioning load will increase from now on, if the numerical value of the air conditioning load tendency is negative, the air conditioning load will decrease from now on, and if the numerical value of the air conditioning load tendency is 0, the air conditioning load will remain unchanged from now on. Further, the larger the value of the air conditioning load tendency is, the larger the degree of increase and decrease is.

The thermal sensation determination unit 34 determines the thermal sensation of the person present in the air-conditioned space based on the temperature data and the operation data of the human body detected by the indoor condition detection sensor 8, the thermal data and the illuminance (light amount obtained by the illuminance sensor) data of the air-conditioned space, and the like. Here, the thermal sensation means a sensation that a person in the air-conditioned space feels hot or cold. The thermal sensation can be expressed as a numerical value, and the thermal sensation has a positive value, and the greater the value, the hotter the person in the conditioned space, the negative value, and the smaller the value, the colder the person in the conditioned space. The determination processing unit 35 performs processing related to the determination. Here, the determination process is performed particularly in relation to whether each actuator is in an operating state, a continuous operating state, or a stopped state. Here, the actuators refer to the compressor 20, the damper, the indoor blowers 6a and 6b, the outdoor blower 21, and the sensor unit 7, but the actuators are not limited thereto. Other components may be included as long as at least the compressor 20, the baffle, the indoor blowers 6a and 6b, and the outdoor blower 21 are included.

The storage unit 36 is a device that stores data and the like necessary for the indoor control unit 37 to obtain numerical values of the air conditioning load tendency and the thermal sensation.

The indoor output unit 38 processes data related to the control instruction from the indoor control unit 37 and transmits a signal to the corresponding device. The devices that receive instructions via the indoor output unit 38 include the indoor fans 6a and 6b, the horizontal air vanes 5, the vertical air vanes 4a and 4b, the front air vane 10, the sensor unit 7, and the like.

Fig. 7 is a timing chart of control of the air conditioner according to embodiment 1. Fig. 8 is a diagram illustrating a control flow of the air conditioner according to embodiment 1.

In the air conditioner according to embodiment 1, as shown in fig. 7, control is performed to bring the compressor 20, the indoor blowers 6a and 6b, and the actuators such as the dampers into a stopped state even while the air conditioner is in operation, as the air conditioning load decreases. Hereinafter, control of the air conditioner according to embodiment 1 will be described with reference to fig. 8.

(step S500)

When the operation of the air conditioner is instructed by the remote controller 16 or the like, the control device starts the operation of the air conditioner and sets each actuator to an operating state.

(step S501)

The control device finds an air conditioning load trend. As described above, the air conditioning load tendency is obtained based on the current and past indoor heat exchanger temperatures, the outside air temperature, the room temperature of the air-conditioned space, the air conditioning capacity, and the amount of solar radiation passing through the window of the air-conditioned space.

(step S502)

The control device determines whether the air conditioning load trend is equal to or less than a threshold Qmin 1-1. If the control device determines that the air conditioning load tendency is equal to or less than the threshold Qmin1-1, the process proceeds to step S503. On the other hand, if the control device determines that the air conditioning load tends to be greater than the threshold Qmin1-1, the control device returns to the process of step S501.

(step S503)

The control device sets the up-down wind direction plates 4a and 4b, the left-right wind direction plate 5, the indoor air-sending devices 6a and 6b, the front wind direction plate 10, and the sensor unit 7 to the stop state shown in fig. 3, and sets the compressor 20 and the outdoor air-sending device 21 to the stop state. At this time, the control device may detect the state of the air-conditioned space by driving only the sensor unit 7 instead of being in a stopped state, as shown in fig. 4.

(step S504)

After each actuator is stopped, the control device determines whether the air conditioning load trend is greater than a threshold value Qmin 1-2. If the control device determines that the air conditioning load tendency is greater than the threshold Qmin1-2, the process returns to step S500. On the other hand, if the control device determines that the air conditioning load tendency is equal to or less than the threshold Qmin1-2, the process proceeds to step S505. Here, the threshold Qmin1-2 may be the same as or different from the threshold Qmin1-1 described above. The comparison with the air conditioning load tendency may be performed, for example, continuously, periodically such as once every 30 minutes, or only once. When determining the air conditioning load tendency, the indoor fans 6a and 6b may be driven to detect the temperature of the indoor heat exchanger 12, the temperature of the air-conditioned space, or the humidity of the air-conditioned space.

(step S505)

The control device maintains the stopped state of each actuator.

(step S506)

The control device determines whether or not the stop of the air conditioner is instructed by the remote controller 16 or the like. If the control device determines that the stop of the air conditioner has been instructed by the remote controller 16 or the like, the process proceeds to step S507. On the other hand, if the control device determines that the stop of the air conditioner has not been instructed by the remote controller 16 or the like, the process returns to step S504. That is, if the stop of the air conditioner is not instructed by the remote controller 16 or the like, the determination of step S504 is repeated.

(step S507)

The control device stops the operation of the air conditioner, and sets the sensor unit 7 in a stopped state when the sensor unit 7 is driven.

The thresholds may be the same at the time of design, or may be individually set for each house according to the heat transfer rate of the house or the like.

As described above, in the air conditioner according to embodiment 1, when an operation instruction is received by the operation means while the air conditioner is stopped, the control device sets all the actuators to the operating state, then obtains the air conditioning load tendency, and sets all the actuators to the stopped state when it is determined that the air conditioning load tendency is equal to or less than the predetermined threshold value.

According to the air conditioner of embodiment 1, when it is determined that the trend of the air conditioning load is equal to or less than the preset threshold value after the start of operation, that is, when the air conditioning load tends to decrease in the future, all the actuators are set to the stopped state. This keeps the comfort of the air-conditioned space unchanged, and stops the unnecessary operation of the actuator, thereby reducing power consumption and improving energy saving performance.

Embodiment mode 2

Hereinafter, although embodiment 2 will be described, the description of the portions overlapping with embodiment 1 will be omitted, and the same or corresponding portions as embodiment 1 will be denoted by the same reference numerals.

Fig. 9 is a timing chart of control of the air conditioner according to embodiment 2. Fig. 10 is a diagram illustrating a control flow of the air conditioner according to embodiment 2.

In the air conditioner according to embodiment 2, as shown in fig. 9, control is performed to bring the compressor 20, the indoor blowers 6a and 6b, and the actuators such as the dampers into a stopped state even while the air conditioner is in operation, as the numerical value of the thermal sensation decreases. Hereinafter, control of the air conditioner according to embodiment 2 will be described with reference to fig. 10.

(step S600)

When the operation of the air conditioner is instructed by the remote controller 16 or the like, the control device starts the operation of the air conditioner and sets each actuator to an operating state.

(step S601)

The control device obtains a numerical value of the thermal sensation of the person present in the air-conditioned space based on the data on the condition of the air-conditioned space detected by the indoor condition detection sensor 8.

(step S602)

The controller determines whether the value of the thermal sensation is equal to or less than a threshold Tonrei 2-1. If the controller determines that the value of the thermal sensation is equal to or less than the threshold Tonrei2-1, the process proceeds to step S603. On the other hand, when the controller determines that the value of the thermal sensation is greater than the threshold Tonrei2-1, the process returns to step S601.

(step S603)

The control device sets the up-down wind direction plates 4a and 4b, the left-right wind direction plate 5, the indoor fans 6a and 6b, and the front wind direction plate 10 to the stopped state shown in fig. 4, and sets the compressor 20 and the outdoor fan 21 to the stopped state. At this time, the control device detects the state of the air-conditioned space by driving only the sensor unit 7 without stopping it as shown in fig. 4, and obtains the numerical value of the thermal sensation.

(step S604)

After the actuators are stopped, the controller determines whether or not the value of the thermal sensation is greater than a threshold Tonrei 2-2. When the controller determines that the value of the thermal sensation is greater than the threshold Tonrei2-2, the process returns to step S600. On the other hand, if the controller determines that the value of the thermal sensation is equal to or less than the threshold Tonrei2-2, the process proceeds to step S605. Here, the threshold value Tonrei2-2 may be the same as or different from the threshold value Tonrei2-1 described above. The comparison with the value of the thermal sensation may be performed continuously, periodically such as once every 30 minutes, or only once. In addition, when determining the value of the thermal sensation, the indoor fans 6a and 6b may be driven to detect the temperature of the heat exchanger, the temperature of the air-conditioned space, and the humidity of the air-conditioned space accurately.

(step S605)

The control device maintains the stopped state of each actuator.

(step S606)

The control device determines whether or not the stop of the air conditioner is instructed by the remote controller 16 or the like. If the control device determines that the stop of the air conditioner has been instructed by the remote controller 16 or the like, the process proceeds to step S607. On the other hand, if the control device determines that the stop of the air conditioner has not been instructed by the remote controller 16 or the like, the process returns to step S604. That is, if the stop of the air conditioner is not instructed by the remote controller 16 or the like, the determination of step S604 is repeated.

(step S607)

The control device stops the operation of the air conditioner and also sets the sensor unit 7 in a stopped state.

In the comparative expressions of steps S602 and S604, the signs of the thresholds are reversed in the case of the cooling operation, and the directions of ≦ and > are reversed in the case of the heating operation, although the above-described comparative expressions are used in the cooling operation. That is, in the case of the heating operation, the value of the thermal sensation is not less than Tonrei2-3 in step S602, and the value of the thermal sensation is less than Tonrei2-4 in step S604. The threshold value in the cooling operation and the threshold value in the heating operation may be the same or different. The threshold values may be set to be the same in design, or may be set individually for each body constitution.

As described above, in the air conditioner according to embodiment 2, the control device obtains the value of the thermal sensation after setting all the actuators to the operating state when receiving the instruction of the operation through the operation means during the stop of the air conditioner, and sets all the actuators to the stopped state when determining that the value of the thermal sensation is equal to or less than the first threshold value set in advance during the cooling operation and when determining that the value of the thermal sensation is equal to or more than the second threshold value set in advance during the heating operation.

According to the air conditioner of embodiment 2, when it is determined that the value of the thermal sensation is equal to or less than the preset threshold value after the start of the operation, that is, when a person in the air-conditioned space feels no heat during the cooling operation and when the person feels no cold during the heating operation, all the actuators are set to the stopped state. This keeps the comfort of the air-conditioned space unchanged, and stops the unnecessary operation of the actuator, thereby reducing power consumption and improving energy saving performance.

Embodiment 3

Hereinafter, although embodiment 3 will be described, parts overlapping with embodiment 1 will not be described, and parts identical to or corresponding to embodiment 1 will be given the same reference numerals.

Fig. 11 is a timing chart of control of the air conditioner according to embodiment 3. Fig. 12 is a diagram showing a control flow of the air conditioner according to embodiment 3.

In the air conditioner according to embodiment 3, as shown in fig. 11, the following control is performed: immediately after the start of operation of the air conditioner, the actuators such as the compressor 20, the indoor fans 6a and 6b, and the dampers are not set to an operating state, but are set to an operating state in accordance with an increase in air conditioning load. Hereinafter, control of the air conditioner according to embodiment 3 will be described with reference to fig. 12.

(step S700)

When the stop of the air conditioner is instructed by the remote controller 16 or the like, the control device stops the operation of the air conditioner.

(step S701)

The control device determines whether or not the operation of the air conditioner is instructed by the remote controller 16 or the like. When the control device determines that the operation of the air conditioner is instructed by the remote controller 16 or the like, the process proceeds to step S702. On the other hand, when the control device determines that the operation of the air conditioner has not been instructed by the remote controller 16 or the like, the process of step S701 is performed again.
