it should be noted that, in the embodiment of the present application, the air conditioner 100 may have only a cooling mode, and the air conditioner 100 may be capable of cooling or heating.

When the air conditioner 100 is of a split type, the indoor unit of the air conditioner 100 may be installed in a ceiling space in a room, and the outdoor unit of the air conditioner 100 may be installed on the outside of an outer wall. The suspended ceiling space is formed by surrounding an indoor ceiling and an indoor wall top, and the outer side of the outer wall refers to the outer side of a house.
Since the refrigerant exists in the air conditioner 100, the refrigerant has a characteristic of releasing a large amount of heat when changing from a gaseous state to a liquid state and absorbing a large amount of heat when changing from a liquid state to a gaseous state.
The indoor unit of the air conditioner 100 may be provided with an indoor heat exchanger, typically an evaporator, and the outdoor heat exchanger in the outdoor unit of the air conditioner 100 may be a condenser. In addition, the condenser, the evaporator and the compressor are sequentially and circularly connected to form a refrigerant circulation loop. At this time, the refrigerant in the evaporator can be sent into the condenser through the compressor, the refrigerant is cooled through the outdoor fresh air entering the condenser, the cooled refrigerant is sent out through the condenser, and the refrigerant is sent into the evaporator after throttling, so that the refrigeration cycle is completed.

In the refrigeration process, the compressor compresses the gaseous refrigerant into the gaseous refrigerant with high temperature and high pressure, and then sends the gaseous refrigerant to the condenser to dissipate heat to become the liquid refrigerant with normal temperature and high pressure, the liquid refrigerant enters the evaporator through the capillary tube assembly, the pressure of the refrigerant is reduced due to the sudden increase of the space after the refrigerant reaches the evaporator from the capillary tube, the liquid refrigerant is vaporized to become the gaseous refrigerant with low temperature, so that a large amount of heat is absorbed, the evaporator is cooled, and the centrifugal fan of the indoor unit of the air conditioner 100 guides indoor air to blow through the evaporator, so that the indoor unit of the air conditioner 100 blows cold air.
The heating process of the air conditioner 100 is the same as the above-described principle of the cooling process, except that the four-way valve is used to make the flow direction of the refrigerant in the condenser and the evaporator opposite to that of the refrigerant during cooling, thereby achieving the purpose of heating.
The temperature measuring assembly 120 includes a non-contact temperature sensor 121, the moving assembly 130 includes a driving unit 131, the temperature sensor 121 is connected to the driving unit 131, and the temperature sensor 121 and the coil 111 are oppositely disposed, the driving unit 131 is configured to drive the temperature sensor 121 to move along a first direction, so that the temperature sensor 121 sequentially detects temperatures of the refrigerant inlet 1111 and the refrigerant outlet 1112 of each coil 111, and a space is provided between the temperature sensor 121 and the coil 111.
It will be appreciated that the temperature sensor 121 is driven by the driving unit 131 to move along the first direction, and the refrigerant inlet 1111 and the refrigerant outlet 1112 of each coil 111 are located on the same side of the coil 111 and are disposed along the first direction, so that the temperature sensor 121 can better monitor the temperature of the refrigerant inlet 1111 and the refrigerant outlet 1112 of each coil 111 when moving along the first direction.

The first direction is perpendicular to the longitudinal direction of the coil 111.
As shown in fig. 1, in some alternative embodiments, the moving assembly 130 further includes a guide rail 132, the guide rail 132 is disposed to extend along the first direction, and the temperature sensor 121 is configured to move along the extending direction of the guide rail 132 under the driving of the driving unit 131.
It will be appreciated that the guide 132 is designed to facilitate movement of the temperature sensor 121 along the direction of extension of the guide 132, i.e., the guide 132 serves as a guide.

It will be appreciated that the motor 1311 rotates to drive the screw to rotate, and the screw then drives the screw sliding sleeve to move along the screw, and then the temperature sensor 121 is driven to move along the screw because the temperature sensor 121 is connected to the screw sliding sleeve.
In some embodiments, a detachable connection manner may be adopted between the temperature sensor 121 and the screw sliding sleeve, and it should be noted that, by setting the temperature sensor 121 and the screw sliding sleeve to be detachably connected, the installation and the detachment of the temperature sensor 121 may be realized, so that the use and the maintenance of the temperature sensor 121 are facilitated.
In other embodiments, the temperature sensor 121 may be fixedly disposed on the lead screw runner.
It should be noted that, in other embodiments, the temperature sensor 121 may be connected to the screw sliding sleeve in an integrally connected manner, so long as the purpose of this embodiment can be achieved by the connection manner that the temperature sensor 121 and the screw sliding sleeve can be fixedly connected, and the connection manner of the temperature sensor 121 and the screw sliding sleeve is not limited herein.
In some alternative embodiments, as shown in fig. 1, the refrigerant inlets 1111 and the refrigerant outlets 1112 of the plurality of coils 111 are alternately and spaced apart along the first direction.
It will be appreciated that such a design facilitates sequential detection by the temperature sensor 121, which in turn may improve the accuracy of the detection.
The size of the interval between the refrigerant inlet 1111 and the refrigerant outlet 1112 of the plurality of coils 111 may be adjusted according to the actual situation, and the embodiment of the present application is not limited herein.
In some alternative embodiments, the spacing between the temperature sensor 121 and the coil 111 ranges from less than 2 cm.
It will be appreciated that such a design may ensure accuracy in detecting temperature while meeting the requirement that the temperature sensor 121 be non-contact.
The distance between the temperature sensor 121 and the coil 111 may be 0.5cm, 1cm, 1.5cm, or 2 cm, or any other value.
Of course, the distance between the temperature sensor 121 and the coil 111 may be greater than 2 cm, and a specific value may be adjusted according to practical situations, which is not limited in this embodiment.
In some alternative embodiments, as shown in FIG. 1, temperature sensor 121 is an infrared thermometer.

In addition, it should be noted that the temperature sensor 121 may be configured as such, and embodiments of the present application are not limited thereto.
The air conditioner provided by the embodiment of the application comprises a coil assembly, a temperature measuring assembly and a moving assembly, wherein the coil assembly comprises a plurality of coils, the coils are sequentially arranged along a first direction, the coils are provided with a refrigerant inlet and a refrigerant outlet, and the refrigerant inlet and the refrigerant outlet of each coil are positioned on the same side of the coil; the temperature measuring assembly comprises a non-contact type temperature sensor, the moving assembly comprises a driving unit, the temperature sensor is connected to the driving unit, the temperature sensor and the coils are oppositely arranged, the driving unit is configured to drive the temperature sensor to move along a first direction, so that the temperature sensor sequentially detects the temperature of a refrigerant inlet and a refrigerant outlet of each coil, and a space is reserved between the temperature sensor and each coil.

Example two
Fig. 2 is a schematic flow chart of an air conditioner temperature collection method provided by an embodiment of the present application, and as shown in fig. 2, the embodiment of the present application provides an air conditioner temperature collection method, which is applied to the air conditioner, and the method includes:
s101: the temperature sensor is driven to move relative to the coil assembly of the air conditioner so that the temperature sensor sequentially detects the first temperature of the refrigerant inlets and the second temperature of the refrigerant outlets of different coils in the coil assembly.
It will be appreciated that the temperature sensor 121 is moved along the positions of the refrigerant inlet 1111 and the refrigerant outlet 1112 of different coils 111 to sequentially detect the first temperature of the refrigerant inlet 1111 and the second temperature of the refrigerant outlet 1112.
Specifically, for the convenience of detection, the refrigerant inlet 1111 and the refrigerant outlet 1112 of different coils 111 may be disposed at the same side, and the temperature sensor 121 is close to the side and moves along a predetermined path, and in particular, the embodiment of the present application is not limited thereto.
Note that, since the refrigerant enters the coil 111 through the refrigerant inlet 1111 and flows out of the refrigerant outlet 1112 to exchange heat, it is not easy to understand that the temperatures of the refrigerant inlet 1111 and the refrigerant outlet 1112 of the same coil 111 are not uniform, that is, the first temperature and the second temperature are different.
S102: the shunt state of the coil assembly is determined based on the first temperature and the second temperature.
It will be appreciated that since there is a difference between the first temperature and the second temperature, the shunt status of the coil assembly 110 can be determined based on the difference.
Of course, the determination may be performed according to separate values of the first temperature and the second temperature, for example, the first temperature may be determined by comparing with a previously preset inlet temperature value, so as to determine whether the temperature of the refrigerant inlet 1111 reaches the preset inlet temperature.
Of course, the second temperature may be determined with the previously preset outlet temperature value, so as to determine whether the temperature of the refrigerant outlet 1112 reaches the preset outlet temperature.
The shunt status of the coil assembly 110 is then determined after a separate comparison can be made.
It should be noted that the shunt state of the coil assembly 110 may include normal and abnormal states.
In some alternative embodiments, the driving of the temperature sensor relative to the coil assembly of the air conditioner specifically includes:
the temperature sensor is driven to move relative to the coil assembly of the air conditioner along a first direction, wherein the first direction is a direction in which a plurality of coils are sequentially arranged.
It will be appreciated that in general the coil assembly 110 includes a plurality of coils 111, and for better detection, the plurality of coils 111 may be sequentially arranged along a first direction, and of course the temperature sensor 121 is moved along the first direction.
In some alternative embodiments, the method includes, prior to moving the temperature sensor relative to the coil assembly of the air conditioner, specifically:
the operating state of the compressor of the air conditioner is determined.
It should be understood that the air conditioner 100 may have a cooling, heating or air-supplying module, and of course, when air-supplying is performed, heat exchange is not required at this time, so the refrigerant does not need to flow, and the temperatures of the refrigerant inlet 1111 and the refrigerant outlet 1112 do not need to be detected.
Therefore, only when the compressor is operated, cooling or heating is performed, that is, when it is determined that the compressor is operated, temperature detection of the refrigerant inlet 1111 and the refrigerant outlet 1112 is performed.
In some alternative embodiments, determining the shunt status of the coil assembly based on the first temperature and the second temperature, specifically includes:
when the compressor works, when the temperature difference between the first temperature corresponding to each coil pipe and the second temperature corresponding to each coil pipe is smaller than or equal to a preset temperature threshold value, the shunting state of the coil pipe assembly is determined to be normal.
It will be appreciated that the preset temperature threshold may be a preset value, and in particular, embodiments of the present application are not limited thereto.
