The compressor 6 compresses the sucked gas refrigerant and discharges it.
The four-way valve 7 changes the direction of the refrigerant flow between the outdoor unit 1 and the indoor unit 2 without changing the direction of the refrigerant flow to the compressor 6. Then, the four-way valve 7 switches between the cooling operation and the heating operation by changing the direction of the flow of the refrigerant.
The outdoor heat exchanger 8 exchanges heat between the refrigerant and outdoor air.
The outdoor expansion valve 9 is a throttle valve that adiabatically expands and evaporates the liquid refrigerant.
The outdoor blower 10 supplies outside air to the outdoor heat exchanger 8.

Next, each device constituting the indoor unit 2 will be described (see FIGS. 1 and 2).
The indoor heat exchanger 12 performs heat exchange between the refrigerant and indoor air.
The indoor blower 13 supplies the indoor air to the indoor heat exchanger 12 and circulates the indoor air passing through the indoor heat exchanger 12 into the room.
The indoor expansion valve 14 is a throttle valve that adiabatically expands and vaporizes the liquid refrigerant. Further, the indoor expansion valve 14 can change the flow rate of the refrigerant flowing through the indoor heat exchanger 12 by changing the throttle amount.

  Note that the indoor unit 2 of the present embodiment is a floor-standing indoor unit installed on a floor F of a room, as shown in FIG. The indoor unit 2 sucks the indoor air from the suction port 15 arranged at the lower part. Then, in the indoor heat exchanger 12 inside the indoor unit 2, heat exchange is performed between the refrigerant and the sucked indoor air, and the temperature-controlled air is blown out from the air outlet 16 arranged at the upper part of the indoor unit 2.

Next, each device constituting the control device 30 will be described (see FIGS. 2 to 4).
First, the operation remote controller 40 has a configuration for a user to operate the air conditioner S, and is installed at the front center of the indoor unit 2 (see FIG. 3). The operation remote controller 40 includes a speaker 41, a display panel 42, a plurality of button switches 43, and a cross key 44 (see FIG. 4).
Note that the operation remote controller 40 can be configured to be operated separately from the indoor unit 2 separately from the indoor unit 2.

The speaker 41 is arranged at a location inside the operation remote controller 40 that cannot be seen from outside. Further, the speaker 41 emits an operation sound at the time of operating the remote controller, and a sound and voice such as voice guidance.
The display panel 42 displays an operation content during the operation on a screen, and displays a selection screen for setting a timer, setting a display language, and the like.
The button switch 43 includes a start / stop switch 43a, a menu switch 43b, and the like.
The start / stop switch 43a (start operation unit) performs a start / stop operation of the air conditioner S by a push operation during a normal air conditioning operation.

The menu switch 43b switches the display content of the display panel 42 by repeating a pressing operation on a plurality of registered setting items (setting of timer, display language, and the like).
The cross key 44 moves the cursor in the display panel 42 switched by the menu switch 43b, and selects a setting desired by the user.
As shown in FIG. 4, the operation remote controller 40 of this embodiment is provided with a return / guide switch 43c and a power saving switch 43d as the button switches 43. Detailed description is omitted.

Next, the leak alarm device 50 will be described (see FIGS. 2 and 4).
The leak alarm device 50 includes a refrigerant sensor 51 (leak detection unit), a leak notification unit 52, and a notification stop unit 53.
The refrigerant sensor 51 (leakage detection means) is configured to detect refrigerant leaked from the indoor unit 2. The refrigerant sensor 51 is disposed near the floor below the refrigerant pipe 3 inside the indoor unit 2.
The refrigerant used in the air conditioner S of the present embodiment is heavier than air and accumulates near the floor when leaking from the indoor unit 2. Therefore, the refrigerant sensor 51 is installed near the floor below the refrigerant pipe 3. Therefore, when the refrigerant is lighter than air, it is desirable to install the refrigerant sensor 51 near the ceiling of the room.

Next, the leak notification means 52 will be described.
The leak notification means 52 is integrally formed with the operation remote controller 40, and includes a display section 52a and a sound transmission section 52b.
The display section 52a also serves as the display panel 42 of the operation remote controller 40, and visually informs the user of the leakage of the refrigerant by displaying warnings such as displaying words, blinking, and changing colors to be emitted.
When the refrigerant leaks, the display content of the display panel 42 is forcibly switched to a content that indicates the refrigerant leak.
In addition, when displaying a word indicating that the refrigerant has leaked, the display unit 52a also displays (notifies) a method of stopping a sound alarm, which will be described later, and a prohibited matter at the time of refrigerant leakage.

The sound transmission unit 52b also serves as the speaker 41 built in the operation remote controller 40, and informs the user of the leakage of the refrigerant by sounding a warning such as an alarm sound or a warning sound.
The notification stop unit 53 also serves as a start / stop switch 43a (start operation unit) of the operation remote controller 40. At the time of the refrigerant leakage warning, the user presses the start / stop switch 43a, so that the sound alarm is stopped without starting / stopping the air conditioner S.

The control means 60 includes an ECU (Electronic Control Unit). In addition, when the refrigerant sensor 51 (leakage detection unit) detects refrigerant leakage, the control unit 60 changes from the normal air-conditioning operation (heating operation, cooling operation, dry operation, etc.) set in the operation menu to the diffusion blowing operation. Force switch to.
The diffusion air blowing operation is an air blowing operation performed to diffuse the refrigerant leaking from the pipe, being heavier than air, and remaining on the floor, and reducing the concentration of the leaked refrigerant.
In the diffusion blowing operation, in the outdoor unit 1, the compressor 6 is forcibly stopped, the normal air-conditioning operation is interrupted, refrigerant leakage is reduced as much as possible, and in the indoor unit 2, the wind direction is directed to the floor. The air is blown at an air volume and a wind speed equal to or greater than a predetermined value.

Further, in the diffusion blowing operation, the control means 60 issues a notification instruction to the leak notification means 52 and switches the start / stop switch 43a to the notification stop means 53.
When the notification stop unit 53 is pressed by the user, the control unit 60 causes the sound transmission unit 52b to interrupt a sound alarm such as an alarm sound or a warning sound.
The wording displayed on the display unit 52a, the blinking of the display panel 42, the change in color, and the like continue.

<Work of the air conditioner>
Next, the operation of the air conditioner S when performing the cooling operation in which the cool air is supplied into the room will be described.
2 indicate the flow of the refrigerant during the cooling operation, and the four-way valve 7 switches as shown by the solid line.
The gas refrigerant which has been compressed by the compressor 6 and has become high temperature and high pressure flows into the outdoor heat exchanger 8 via the four-way valve 7.
The gas refrigerant that has flowed into the outdoor heat exchanger 8 radiates heat to the outside air supplied by the outdoor blower 10 while passing through the outdoor heat exchanger 8 and condenses to become a low-temperature and high-pressure liquid refrigerant.

The liquid refrigerant condensed from the gas refrigerant is sent to the indoor unit 2 via the outdoor expansion valve 9. Note that, at this time, since the outdoor expansion valve 9 does not function as an expansion valve, the refrigerant does not adiabatically expand and passes as a liquid refrigerant.
The liquid refrigerant flowing into the indoor unit 2 flows into the indoor heat exchanger 12 while being adiabatically expanded by the indoor expansion valve 14.
When the liquid refrigerant expands adiabatically, it draws latent heat of evaporation from the indoor air supplied by the indoor blower 13 and evaporates to become a low-temperature low-pressure gas refrigerant.
Then, the indoor air deprived of the latent heat of evaporation is relatively cooled, and cool air is blown into the room.

The gas refrigerant vaporized from the liquid refrigerant is sent to the outdoor unit 1.
The gas refrigerant returned to the outdoor unit 1 passes through the four-way valve 7 and flows into the accumulator 5.
In the gas refrigerant flowing into the accumulator 5, the mixed liquid refrigerant is separated by the accumulator 5, adjusted to a predetermined dryness, supplied to the compressor 6, and compressed again.
As described above, by circulating the refrigerant in the refrigeration cycle in the direction of the solid arrow, a cooling operation for supplying cool air to the room is realized.

Next, the operation of the air conditioner S when performing a heating operation in which warm air is supplied to the room will be described.
2 indicates the flow of the refrigerant during the heating operation, and the four-way valve 7 switches as shown by the dotted line.
The high-temperature and high-pressure gas refrigerant compressed by the compressor 6 flows into the indoor unit 2 via the four-way valve 7.
The gas refrigerant that has flowed into the indoor heat exchanger 12 radiates heat to the indoor air supplied by the indoor blower 13 and condenses while passing through the indoor heat exchanger 12, and becomes a low-temperature and high-pressure liquid refrigerant.
Then, the received indoor air is relatively heated, and warm air is blown into the room.

The liquid refrigerant condensed from the gas refrigerant passes through the indoor expansion valve 14 and is sent to the outdoor unit 1. At this time, since the indoor expansion valve 14 does not function as an expansion valve, the refrigerant does not adiabatically expand and passes as a liquid refrigerant.
The liquid refrigerant flowing into the outdoor unit 1 flows into the outdoor heat exchanger 8 while being adiabatically expanded by the outdoor expansion valve 9.
When the liquid refrigerant expands adiabatically, it takes off latent heat of vaporization from the outside air supplied by the outdoor blower 10 and vaporizes to become a low-temperature low-pressure gas refrigerant.

The gas refrigerant that has been vaporized from the liquid refrigerant and has flowed out of the outdoor heat exchanger 8 passes through the four-way valve 7 and flows into the accumulator 5.
In the gas refrigerant flowing into the accumulator 5, the mixed liquid refrigerant is separated by the accumulator 5, adjusted to a predetermined dryness, supplied to the compressor 6, and compressed again.
As described above, the refrigerant circulates in the refrigeration cycle in the direction of the dotted arrow, thereby realizing a heating operation for supplying warm air to the room.

Next, the operation of the leak alarm device 50 will be described.
The refrigerant sensor 51 constantly measures whether or not the air conditioner S is in an air-conditioning operation. When the refrigerant leaks from the refrigerant pipe, the refrigerant sensor 51 detects the refrigerant.
The control means 60 receives the refrigerant detection (leakage of the refrigerant) by the refrigerant sensor 51 and starts the diffusion blowing operation.
In addition, when the leakage of the refrigerant is detected during the normal air-conditioning operation (heating operation, cooling operation, dry operation, etc.), the air-conditioning operation is stopped and the diffusion blowing operation is started. When the leakage of the refrigerant is detected while the air-conditioning operation is stopped, the diffusion blowing operation is started as it is.

Next, the control means 60 instructs the leak notification means 52 to report the leak.
The leak notifying means 52 informs the display of the display panel 42 of the operation remote controller 40 from FIG. 4 displaying the operation content during the normal air-conditioning operation to FIG. 5 displaying the detection of the refrigerant leakage from FIG. Switch to content.
Further, the leak notification unit 52 outputs a sound alarm such as an alarm sound and an alarm sound from the speaker 41 (sound transmission unit) of the operation remote controller 40.
The user who has noticed the alarm presses the start / stop switch 43a (notification stop unit) according to the display on the display panel 42.

The control means 60 instructs the interruption of the alarm in response to the pressing operation of the start / stop switch 43a (notification stop means) by the user.
The leak notification means 52 stops the sound alarm issued from the speaker 41.
That is, the sound alarm stops when the start / stop switch 43a is pressed.

In addition, the display and blinking of the wording on the display unit 52a, a change in color, and the like, and the diffusion blowing operation are continued.
Also, the leak notification unit 52 is configured to stop blinking of the display panel 42, change of the emitted color, and the like at the time of stopping the sound alarm, and continue to display only the wording of the content of the warning on the display panel 42. Is also good.
Further, the leak notification means 52 may be set to switch the display on the display panel 42 to the contact information of the repair window at the timing when the sound alarm is stopped.
For example, as shown in FIG. 6, the telephone number of the repair window is displayed, and the user is urged to request a repair.

When the user requests repair according to the instructions displayed on the display panel 42, the repair worker arrives.
The repair worker operates the operation remote controller to stop the leak alarm device 50 and repair the air conditioner S. When stopping the leak alarm device 50, the repair operator operates the operation remote controller according to an operation procedure that is not described in the instruction manual or the like and is not known to the user.

An operation procedure that is not known to the user is configured by an operation pattern that is not performed during a normal air-conditioning operation.
An example of such an operation pattern is a combination operation such as simultaneously pressing and holding the two button switches 43 on the operation remote controller 40.
As another example of the operation pattern, the start / stop switch 43a is pressed after the "up" twice, the "right" once, the "down" twice, and the "left" once for the cross key 44. And the like.
Further, the operation pattern of stopping the leak alarm device 50 can be achieved by operating an alarm release switch, which is normally installed in a place where the user does not see the inside of the indoor unit 2.

Next, the operation and effect of the configuration of the first embodiment will be described.
In the present embodiment, a method is employed in which the notification (sound alarm) by the leak notification means 52 (speaker 41) is stopped by operating the notification stop means 53 (start / stop switch 43a).
This can prevent the user from shutting off the power supply and the breaker (not shown) of the air conditioner S and stopping the diffusion ventilation operation in order to stop the notification (sound alarm).

In addition, by providing the notification stopping means 53, the user can stop the notification (sound alarm) without trying various operations (without trial and error) in order to stop the notification (sound alarm).
As a result, the time during which the user feels the notification (sound alarm) to be uncomfortable can be reduced, and the uncomfortable feeling can be reduced.

In the present embodiment, the leakage of the refrigerant is reported by the display warning by the display unit 52a and the sound warning by the sound transmission unit 52b.
By operating the notification stopping means 53, only the sound alarm is stopped.
As a result, it is possible to keep the user informed that the refrigerant is leaking while reducing the discomfort of the user.

In the present embodiment, when stopping the leak alarm device 50, the repair operator operates the operation remote controller according to an operation procedure that is not described in an instruction manual or the like and is not known to the user.
Thus, it is possible to prevent the leak alarm device 50 from being stopped by mistake when the user tries to stop the sound alarm and the diffusion ventilation operation is stopped.

In the present embodiment, the notification stop unit 53 is set as a start operation unit (start / stop switch 43a) during normal air conditioning operation. That is, the start operation unit (start / stop switch 43 a) also functions as the notification stop unit 53.
With such a configuration, at the time of refrigerant leakage, the notification / stop function is set (given) to the start / stop switch 43a, and the start / stop function set in the start operation unit during normal operation is forcibly stopped. be able to.
Further, the present invention is suitable for a user who performs a sensory action to stop the operation of the air conditioner S and stop the sound alarm without confirming the display alarm of the display unit 52a.

Furthermore, by forcibly stopping the start / stop function set in the start operation unit during the normal operation, it is possible to prevent the user from stopping the diffusion ventilation operation.
On the other hand, for example, when the notification stop unit 53 is set to an operation unit other than the start / stop switch 43a, even after the sound alarm is stopped, the start / stop switch 43a is operated to perform the diffusion blowing operation. It can be stopped.

In addition, in this embodiment, it is set so that the diffusion blowing operation is continued until the repair worker arrives.
However, the setting may be such that the diffusion blowing operation is temporarily stopped at the stage when the refrigerant concentration is reduced, and the diffusion blowing operation is performed again when the leaked refrigerant concentration increases again. Such a setting is suitable for a situation in which a user receives a warning and opens a window, a door, or the like, and the leaked refrigerant is diffused outside.

<Second embodiment>
Next, a second embodiment of the air conditioner S will be described with reference to the drawings. The same components as those of the above-described air conditioner S are denoted by the same reference numerals, and redundant description will be omitted.

The touch panel 45 has the functions of the display panel 42 and the button switch 43 of the operation remote controller 40 of the first embodiment.

The touch panel 45 displays, as the display panel 42, the details of the operation during driving on a screen, and displays a selection screen for setting a timer, setting a display language, and the like. In addition, the touch panel 45 serves as a display section 52a of the leak notification means 52 to visually notify the user of the leakage of the refrigerant by displaying a word, blinking, or changing the color of the displayed warning.
Further, the touch panel 45 functions as the notification stop unit 53 instead of performing the pressing operation of the button switch 43 by the user touching the icon displayed on the screen.
The icons are composed of figures and symbols displayed on the screen of the display panel 42.

Next, the operation of the leak alarm device 50 will be described.
The flow from when the refrigerant sensor 51 detects the leakage of the refrigerant to when a sound alarm is issued from the speaker 41 of the operation remote controller 40A is the same as that in the first embodiment.
In addition, the touch panel 45 of the operation remote controller 40A switches to a screen for notifying a refrigerant leak and displays a “sound alarm interruption icon” (notification stop unit).
The user who noticed the alarm touches the “sound alarm interruption icon” according to the display on the touch panel 45.

The control unit 60 instructs interruption of the alarm in response to the user touching the “sound alarm interruption icon” (notification stop unit).
The leak notification means 52 stops the sound alarm issued from the speaker 41.
When the user requests repair according to the instructions displayed on the touch panel 45, the repair worker arrives, and the repair worker performs repair in the same procedure as in the first embodiment.

Next, the operation and effect of the configuration of the second embodiment will be described.
A touch panel 45 is employed in the operation remote controller 40A of the present embodiment. Then, the sound alarm can be stopped by touching the “sound alarm suspension icon” displayed on the screen as the notification stopping means 53.
For this reason, the user can intuitively understand the emergency operation procedure without checking the instruction manual or the like.
Thus, the user can stop the sound alarm promptly, so that the time when the user feels the notification (sound alarm) to be uncomfortable can be reduced, and the discomfort can be reduced.

For a function whose operation is to be prohibited by the user, the corresponding icon need not be displayed on the touch panel 45 screen.
That is, during the diffusion ventilation operation, the “start / stop icon” and the “leakage alarm device stop icon” are not displayed on the screen, thereby preventing the user from accidentally stopping the diffusion ventilation operation. it can.
