The problem of refrigeration plant to humidity and temperature control's accuracy lower is solved.

Fig. 1 is a schematic diagram of a refrigeration unit 10 according to the present application. As shown in fig. 1, the refrigeration appliance 10 may include a control device 11 (not shown in fig. 1), a temperature and humidity sensor 12, a compressor 13, a heater 14, an evaporator 15, and a fan 16.

With reference to fig. 1, fig. 2 shows a schematic connection structure of a refrigeration apparatus provided by the present application. Wherein, the temperature and humidity sensor 12, the compressor 13, the heater 14, the evaporator 15 and the fan 16 are all connected with the control device 11.

The refrigeration device 10 may be a red wine refrigeration device, a medicine refrigeration device, a blood refrigeration device, a medical low-temperature device, a cool box, a commercial display device, or other devices or devices having a low-temperature storage function, which is not limited in the embodiments of the present invention.

The temperature and humidity sensor 12 is used to detect the temperature and humidity inside the refrigeration apparatus 10.

And a compressor 13 for inputting cold air into the interior of the refrigerator 10 in an operation state.

The specific process is as follows: the compressor 13 inputs cold air into the evaporator 15, and the cold air evaporated by the evaporator 15 exchanges heat with air inside the refrigerator 10, thereby lowering the temperature of the air inside the refrigerator 10.

And a heater 14 for inputting hot gas to the evaporator 15 in an operation state.

The specific process is as follows: the heater 14 inputs hot air to the evaporator 15, and the hot air evaporated by the evaporator 15 exchanges heat with the air in the refrigerator 10, thereby increasing the temperature of the air inside the refrigerator 10.

An evaporator 15 for exchanging heat with the air in the refrigerator 10.

The fan 13 is used to blow off moisture on the surface of the evaporator 15 or blow air in the refrigerator 10 toward the evaporator 15 in an operating state.

And a control device 11 for controlling at least one of the compressor 13, the heater 14, the evaporator 15 or the fan 16 to start or stop operating in an operating state to achieve precise control of the temperature and humidity inside the refrigeration apparatus 10.

Alternatively, as shown in fig. 3 in conjunction with fig. 1 or 2, the refrigerator 10 may further include a display panel 17, a storage compartment 18, a refrigerating compartment 19, and a freezing compartment 20.

Optionally, a display panel 17 is used to display the humidity and temperature inside the refrigerator 10. The display panel 17 may also adjust the humidity and temperature inside the refrigerator 10 in response to user operation.

Alternatively, temperature and humidity sensors (not shown in fig. 3) may be installed in each of the locker room 18, the refrigerating room 19, and the freezing room 20 to detect the temperature and humidity in the locker room 18, the refrigerating room 19, and the freezing room 20. When temperature and humidity sensors are installed in the storage chamber 18, the refrigerating chamber 19 and the freezing chamber 20, the control device 11 may control the temperature and humidity of the storage chamber corresponding to the temperature and humidity sensor according to the temperature and humidity detected by the temperature and humidity sensor of any one of the different storage chambers (i.e., the storage chamber 18, the refrigerating chamber 19 and the freezing chamber 20).

The operation of the refrigeration apparatus 10 provided in the embodiment of the present application is described below.

The control method of the refrigeration equipment 10 provided by the embodiment of the application comprises the following steps: when the control device 11 determines that the humidity detected by the temperature and humidity sensor 12 at the first moment is not within the preset humidity range and the temperature at the first moment is within the preset temperature range, it indicates that the humidity inside the refrigeration apparatus 10 is abnormal and the temperature is normal, and the control device needs to control the target device (i.e., the compressor 13 or the heater 14) to start and operate and control the fan 16 to start and operate (i.e., dehumidify or humidify the inside of the refrigeration apparatus 10).

Specifically, when the control device 11 determines that the humidity at the first moment detected by the temperature and humidity sensor 12 is greater than a first humidity threshold and the temperature at the first moment is within a preset temperature range, the compressor 13 and the fan 16 are controlled to start operation (referred to as a "dehumidification flow" for short), and when the control device 11 determines that the humidity at the first moment detected by the temperature and humidity sensor 12 is less than a second humidity threshold and the temperature at the first moment is within the preset temperature range, the heater 14 and the fan 16 are controlled to start operation (referred to as a "humidification flow" for short). The first preset humidity threshold is the maximum value of the preset humidity range. The second predetermined humidity threshold is the minimum value of the predetermined humidity range.

The "dehumidification flow" will be described first.

Referring to fig. 1, 2 and 3, as shown in fig. 4, the "dehumidification flow" may include the following steps S401 to S406.

S401, the control device 11 receives a first humidity and a first temperature detected by the temperature and humidity sensor 12 at a first time.

Because the temperature and humidity sensor 12 is installed inside the refrigeration apparatus 10, the temperature and humidity sensor 12 can periodically detect the temperature and humidity inside the refrigeration apparatus 10, and the first humidity is the humidity inside the refrigeration apparatus 10 at the first time. Similarly, the first temperature is the temperature inside the refrigeration unit 10 at the first time.

S402, the control device 11 determines whether the first humidity detected by the temperature and humidity sensor 12 is greater than a first humidity threshold, and whether the first temperature is within a preset temperature range.

The first humidity threshold is a maximum value required for the articles stored in the refrigeration device 10, and if the humidity in the refrigeration device 10 is greater than the first humidity threshold, the quality of the articles stored in the refrigeration device 10 is affected.

If the first humidity detected by the temperature and humidity sensor 12 is greater than the first humidity threshold and the first temperature is within the preset temperature range, S403 is executed. Otherwise, S401 is executed.

And S403, the control device 11 controls the compressor 13 and the fan 16 to start running.

When the control device 11 determines that the first humidity detected by the temperature and humidity sensor 12 is greater than the first humidity threshold and the first temperature is within the preset temperature range, in this case, the humidity inside the refrigeration apparatus 10 is abnormal and the temperature is normal, and the control device 11 needs to dehumidify the inside of the refrigeration apparatus 10. Therefore, the control device 11 controls the compressor 13 and the fan 16 to start operation. At this time, the compressor 13 inputs cold air to the evaporator 15. The evaporator 15 begins to decrease in temperature upon cooling. Subsequently, the fan 16 is operated to blow air in the refrigerator 10 toward the evaporator 15. After meeting the cold evaporator 15, the air is condensed into ice water and is discharged from the drain pipe, so that the humidity inside the refrigeration equipment 10 is reduced, and the dehumidification effect is realized.

Optionally, after the compressor 13 inputs cold air to the evaporator 15, the evaporator 15 needs a process of reducing the temperature, and at this time, if the fan 16 is turned on, the air inside the refrigeration device 10 may not be condensed into ice water through the evaporator 15, the heat generated after the fan 16 is turned on may increase the humidity inside the refrigeration device 10. Therefore, in order to better achieve the dehumidification effect, the control device 11 may control the compressor 13 to start operation, and control the fan 16 to start operation after the operation duration of the compressor 13 is greater than or equal to the first preset time period. In this way, the evaporator 15 can exchange heat with the air blown by the fan 16 after the temperature is reduced, so that the air in the refrigerator 10 is condensed into ice water and discharged through the drain pipe, thereby achieving a better dehumidification effect.

Illustratively, the control device 11 is configured to control the speed of the motor at 11: 00, determining that the first humidity detected by the temperature and humidity sensor 12 is 15 g/cubic meter and is greater than a first humidity threshold (10 g/cubic meter), and the first temperature is 5 ℃, and when the first temperature is within a preset temperature range (0 ℃ to 10 ℃), under such a condition, the humidity in the refrigeration equipment 10 is abnormal, the temperature is normal, the control device 11 needs to dehumidify the inside of the refrigeration equipment 10, the control device 11 controls the compressor 13 to start and operate for 10 seconds, and then the control device 11 controls the fan 16 to start and operate.

S404, the control device 11 receives the second humidity and the second temperature detected by the temperature and humidity sensor 12 at the second time.

Wherein the second humidity is the humidity inside the refrigeration apparatus 10 at the second moment. The second temperature is the temperature inside the refrigerator 10 at the second moment. The second time is a time after the first time.

S405, the control device 11 determines whether the second humidity detected by the temperature and humidity sensor 12 is within a preset humidity range, and whether the second temperature is within a preset temperature range.

After the control device 11 controls the compressor 13 and the fan 16 to start operation, since the humidity in the refrigeration apparatus 10 is continuously decreased, the control device 11 determines whether the second humidity detected by the temperature and humidity sensor 12 is within the preset humidity range and whether the second temperature is within the preset temperature range. If the control device 11 determines that the second humidity detected by the temperature and humidity sensor 12 is within the preset humidity range and the second temperature is within the preset temperature range, S406 is executed. Otherwise, S404 is executed.

And S406, the control device 11 controls the compressor 13 and the fan 16 to stop running.

When the control device 11 determines that the second humidity detected by the temperature and humidity sensor 12 is within the preset humidity range and the second temperature is within the preset temperature range, under the condition, the humidity in the refrigeration device 10 is normal, the temperature is normal, the humidity and the temperature in the refrigeration device 10 meet the humidity required by the stored goods, and the dehumidification is not required to be continued, so that the control device 11 controls the compressor 13 and the fan 16 to stop operating.

Illustratively, the control device 11 is configured to control the speed of the motor at 11: 30, determining that the second humidity detected by the temperature and humidity sensor 12 is 5 g/cubic meter and is within a preset humidity range (1 g/cubic meter-10 g/cubic meter), and the second temperature is 5 ℃ and is within a preset temperature range (0 ℃ to 10 ℃), under the condition, the humidity in the refrigeration equipment 10 is normal, the temperature is normal, the humidity and the temperature in the refrigeration equipment 10 meet the humidity required by stored goods, and the dehumidification is not required to be continued, so that the control device 11 controls the compressor 13 and the fan 16 to stop operating.

In the above processes of S401 to S406, since the control device 11 determines that the temperatures detected by the temperature and humidity sensor 12 at the first time and the second time are both within the preset temperature range, in practical applications, after the control device 11 controls the compressor 13 and the fan 16 to start operating, the temperature inside the refrigeration apparatus 10 may be reduced below the minimum value of the preset temperature range. Therefore, in conjunction with FIG. 4, as shown in FIG. 5, after S403, S501-S506 may also be included.

S501, the control device 11 receives a third humidity and a third temperature detected by the temperature and humidity sensor 12 at a third time.

Wherein the third humidity is the humidity inside the refrigeration apparatus 10 at the third moment. The third temperature is the temperature inside the refrigerator 10 at the third time. The third time is a time after the first time.

S502, the control device 11 determines whether the third humidity detected by the temperature and humidity sensor 12 is greater than the first humidity threshold, and whether the third temperature is less than a first preset temperature.

Wherein the first preset temperature is less than the minimum value of the preset temperature range.

After the control device 11 controls the compressor 13 and the fan 16 to start operation, the temperature in the refrigeration apparatus 10 is gradually decreased. In order to prevent the temperature in the refrigeration apparatus 10 from decreasing too fast, and further affecting the articles stored in the refrigeration apparatus 10, the control device 11 needs to receive the third humidity and the third temperature detected by the temperature and humidity sensor 12 at the third time, and then determine whether the third humidity is greater than the first humidity threshold, and whether the third temperature is less than the first preset temperature. If the control device 11 determines that the third humidity detected by the temperature and humidity sensor 12 is greater than the first humidity threshold and the third temperature is less than the first preset temperature, S503 is executed. Otherwise, S501 is executed.

S503, the control device 11 controls the compressor 13 and the fan 16 to stop running and controls the heater 14 to start running.

When the control device 11 determines that the third humidity detected by the temperature and humidity sensor 12 is greater than the first humidity threshold and the third temperature is less than the first preset temperature, the temperature in the refrigeration apparatus 10 is lower than the preset temperature of the goods in the refrigeration apparatus 10. In this case, the humidity and the temperature in the refrigerator 10 are abnormal, and in practical use, the priority of the temperature control is higher than that of the humidity control for the goods in the refrigerator 10, and therefore, the control device 11 controls the compressor 13 and the fan 16 to stop operating, preventing the temperature from continuously decreasing. Secondly, the heater 14 is controlled to start operation, and the heater 14 inputs hot air to the evaporator 15 in an operating state, so that when the temperature of the evaporator 15 rises, the temperature in the refrigeration device 10 can be increased, and the temperature can be prevented from continuously decreasing.

Alternatively, the control device 11 may control the heater 14 to start operation while the compressor 13 and the fan 16 stop operating; the compressor 13 and the fan 16 may be controlled to stop operating, and then the heater 14 may be controlled to start operating. The embodiments of the present application do not limit this.

Illustratively, the control device 11 is configured to control the speed of the motor at 11: in practical application, for the articles in the refrigeration equipment 10, the priority of temperature control is greater than the priority of humidity control, so that the control device 11 controls the compressor 13 and the fan 16 to stop operating, and controls the heater 14 to start operating.

S504, the control device 11 receives the fourth humidity and the fourth temperature detected by the temperature and humidity sensor 12 at the fourth time.

Wherein the fourth humidity is the humidity inside the refrigeration appliance 10 at the fourth moment. The fourth temperature is the temperature inside the refrigerator 10 at the fourth moment. The fourth time is a time after the third time.

S505, the control device 11 determines whether the fourth humidity detected by the temperature and humidity sensor 12 is greater than the first humidity threshold, and whether the fourth temperature is within the preset temperature range.

The control device 11 controls the compressor 13 and the fan 16 to stop operating, and the temperature in the refrigerator 10 gradually increases after the heater 14 starts operating. In order to prevent the temperature in the refrigeration apparatus 10 from rising too fast and further affecting the articles stored in the refrigeration apparatus 10, the control device 11 needs to receive a fourth temperature detected by the temperature and humidity sensor 12 at a fourth time, and then determine whether the fourth humidity detected by the temperature and humidity sensor 12 is greater than the first humidity threshold, and whether the fourth temperature is within the preset temperature range. If the control device 11 determines that the fourth humidity detected by the temperature and humidity sensor 12 is greater than the first humidity threshold and the fourth temperature is within the preset temperature range, S506 is executed. Otherwise, S504 is executed.

And S506, the control device 11 controls the heater 14 to stop running and controls the compressor 13 and the fan 16 to start running.

When the control device 11 determines that the fourth humidity detected by the temperature and humidity sensor 12 is greater than the first humidity threshold value and the fourth temperature is within the preset temperature range, in this case, the humidity in the refrigeration equipment 10 is abnormal and the temperature is normal, the control device 11 only needs to dehumidify the refrigeration equipment 10 and does not need to increase the temperature, that is, the heater 14 does not need to input hot air to the evaporator 15, and the control device 11 controls the heater 14 to stop operating. Since the fourth humidity is greater than the first humidity threshold value, the control device 11 controls the compressor 13 and the fan 16 to start operation, and continues the dehumidification process.

Alternatively, the control device 11 may control the compressor 13 and the fan 16 to start operation while the heater 14 stops operating; alternatively, the heater 14 may be controlled to stop operating, and then the compressor 13 and the fan 16 may be controlled to start operating. The embodiments of the present application do not limit this.

Illustratively, the control device 11 is configured to control the speed of the motor at 11: 20, it is determined that the fourth humidity detected by the temperature and humidity sensor 12 is 13 g/cubic meter and is greater than the first humidity threshold (10 g/cubic meter), and the fourth temperature is 1 degree centigrade, and when the fourth humidity is within the preset temperature range (0-10 degrees centigrade), under such a condition, the humidity in the refrigeration equipment 10 is abnormal, the temperature is normal, the control device 11 only needs to dehumidify the refrigeration equipment 10, and does not need to heat up, then the control device 11 controls the heater 14 to stop operating, and controls the compressor 13 and the fan 16 to start operating.

The "humidification flow" will be described below.

Referring to fig. 1, 2 and 3, as shown in fig. 6, the "humidification flow" may include the following steps S601 to S606.

S601, the control device 11 receives a first humidity and a first temperature detected by the temperature and humidity sensor 12 at a first time.

Referring to the description of S401 above, the control device 11 receives the first humidity and the first temperature detected by the temperature and humidity sensor 12 at the first time. The first humidity is the humidity inside the refrigeration device 10 at the first moment. Similarly, the first temperature is the temperature inside the refrigeration unit 10 at the first time.

S602, the control device 11 determines whether the first humidity detected by the temperature and humidity sensor 12 is smaller than a second humidity threshold, and whether the first temperature is within a preset temperature range.

The second humidity threshold is a minimum value required for the goods stored in the refrigeration device 10, and if the humidity in the refrigeration device 10 is less than the second humidity threshold, the quality of the goods stored in the refrigeration device 10 is affected.

If the first humidity detected by the temperature and humidity sensor 12 is smaller than the second humidity threshold and the first temperature is within the preset temperature range, S603 is executed. Otherwise, S601 is executed.

And S603, controlling the heater 14 and the fan 16 to start operation by the control device 11.

When the control device 11 determines that the first humidity detected by the temperature and humidity sensor 12 is less than the second humidity threshold and the first temperature is within the preset temperature range, in this case, the humidity inside the refrigeration apparatus 10 is abnormal and the temperature is normal, and the control device 11 needs to humidify the inside of the refrigeration apparatus 10. Accordingly, the control device 11 controls the heater 14 and the fan 16 to start operation. At this time, the heater 14 inputs hot gas to the evaporator 15. After the evaporator 15 is heated, the temperature begins to rise, and the cold frost on the surface of the evaporator 15 is heated to form water vapor. Subsequently, after the fan 16 is started to operate, the water vapor on the evaporator 15 is blown away to the inside of the refrigeration equipment 10, so that the humidity inside the refrigeration equipment 10 is improved, and the humidifying effect is realized.

Alternatively, after the heater 14 inputs hot air into the evaporator 15, the evaporator 15 needs a process of raising the temperature and forming cold frost on the surface into water vapor, and at this time, if the fan 16 is turned on, no water vapor is formed on the evaporator 15, which may cause waste of energy consumption. Therefore, in order to better achieve the humidification effect, the control device 11 may control the heater 14 to start operation, and control the heater 14 to stop operation and the fan 16 to start operation after the operation time of the heater 14 is greater than or equal to a second preset time period. In this way, after the temperature of the evaporator 15 rises and water vapor is formed on the surface, the fan 16 blows the water vapor on the evaporator 15 to the inside of the refrigeration device 10, and the humidifying effect is better achieved.

Illustratively, the control device 11 is controlled at 10: 00, determining that a first humidity detected by the temperature and humidity sensor 12 is 0.5 g/cubic meter and smaller than a second humidity threshold (1 g/cubic meter), and the first temperature is 5 ℃, and when the first temperature is within a preset temperature range (0 ℃ to 10 ℃), under the condition, the humidity in the refrigeration equipment 10 is abnormal, the temperature is normal, the control device 11 needs to humidify the interior of the refrigeration equipment 10, the control device 11 controls the heater 14 to start and operate for 10 seconds, and then the control device 11 controls the heater 14 to stop operating and controls the fan 16 to start and operate.

S604, the control device 11 receives the second humidity and the second temperature detected by the temperature/humidity sensor 12 at the second time.

S605, the control device 11 determines whether the second humidity detected by the temperature and humidity sensor 12 is within a preset humidity range, and whether the second temperature is within a preset temperature range.

After the control device 11 controls the heater 14 and the fan 16 to start operation, since the humidity in the refrigeration apparatus 10 will continuously rise, the control device 11 determines whether the second humidity detected by the temperature and humidity sensor 12 is within the preset humidity range and whether the second temperature is within the preset temperature range. If the control device 11 determines that the second humidity detected by the temperature and humidity sensor 12 is within the preset humidity range and the second temperature is within the preset temperature range, S606 is executed. Otherwise, S604 is executed.

And S606, the control device 11 controls the heater 14 and the fan 16 to stop running.

When the control device 11 determines that the second humidity detected by the temperature and humidity sensor 12 is within the preset humidity range and the second temperature is within the preset temperature range, in this case, the humidity in the refrigeration apparatus 10 is normal, the temperature is normal, and the humidity and the temperature in the refrigeration apparatus 10 meet the humidity required for storing the articles, and there is no need to continue humidification, so the control device 11 controls the heater 14 and the fan 16 to stop operating.

Illustratively, the control device 11 is controlled at 10: 30, determining that the second humidity detected by the temperature and humidity sensor 12 is 5 g/cubic meter and is within a preset humidity range (1 g/cubic meter-10 g/cubic meter), and the second temperature is 5 ℃ and is within a preset temperature range (0 ℃ to 10 ℃), under the condition, the humidity in the refrigeration equipment 10 is normal, the temperature is normal, the humidity and the temperature in the refrigeration equipment 10 meet the humidity required by stored goods, and the humidification does not need to be continued, so that the control device 11 controls the heater 14 and the fan 16 to stop operating.

In the above processes of S601 to S606, since the control device 11 determines that the temperatures detected by the temperature and humidity sensor 12 at the first time and the second time are both within the preset temperature range, in practical applications, after the control device 11 controls the heater 14 and the fan 16 to start operating, the temperature inside the refrigeration apparatus 10 may be increased to be above the maximum value of the preset temperature range. Therefore, in conjunction with fig. 6, as shown in fig. 7, after S603, S701-S706 may also be included.

S701, the control device 11 receives a fifth humidity and a fifth temperature detected by the temperature and humidity sensor 12 at a fifth time.

Wherein the fifth humidity is the humidity inside the refrigeration appliance 10 at the fifth moment. The fifth temperature is the temperature inside the refrigerator 10 at the fifth moment. The fifth time is a time after the first time.

S702, the control device 11 determines whether the fifth humidity detected by the temperature and humidity sensor 12 is less than the first humidity threshold, and whether the fifth temperature is greater than a second preset temperature.

Wherein the second preset temperature is greater than the maximum value of the preset temperature range.

After the control device 11 controls the heater 14 and the fan 16 to start operation, the temperature in the refrigeration apparatus 10 will gradually increase. In order to prevent the temperature in the refrigeration apparatus 10 from rising too fast and further affecting the articles stored in the refrigeration apparatus 10, the control device 11 needs to receive the fifth humidity and the fifth temperature detected by the temperature and humidity sensor 12 at the fifth moment, and then determine whether the fifth humidity is smaller than the first humidity threshold, and whether the fifth temperature is greater than the second preset temperature. If the control device 11 determines that the fifth humidity detected by the temperature and humidity sensor 12 is smaller than the first humidity threshold and the fifth temperature is greater than the second preset temperature, S703 is executed. Otherwise, S701 is executed.

And S703, the control device 11 controls the heater 14 and the fan 16 to stop running and controls the compressor 13 to start running.

When the control device 11 determines that the fifth humidity detected by the temperature and humidity sensor 12 is less than the first humidity threshold and the fifth temperature is greater than the second preset temperature, the temperature in the refrigeration apparatus 10 is greater than the preset temperature of the goods in the refrigeration apparatus 10. In this case, the humidity and the temperature in the refrigerator 10 are abnormal, and in practical use, the priority of the temperature control is higher than that of the humidity control for the items in the refrigerator 10, and therefore, the control device 11 controls the heater 14 and the fan 16 to stop operating, preventing the temperature from continuously rising. Secondly, the compressor 13 is controlled to start operation, and the compressor 13 inputs cold air to the evaporator 15 in an operation state, so that when the temperature of the evaporator 15 is reduced, the temperature in the refrigeration device 10 can be reduced, and the temperature is prevented from being continuously increased.

Alternatively, the control device 11 may control the heater 14 and the fan 16 to stop operating, and at the same time, control the compressor 13 to start operating; alternatively, the heater 14 and the fan 16 may be controlled to stop operating, and then the compressor 13 may be controlled to start operating. The embodiments of the present application do not limit this.

Illustratively, the control device 11 is controlled at 10: when the fifth humidity detected by the temperature and humidity sensor 12 is determined to be 0.8 g/cubic meter and smaller than the first humidity threshold (1 g/cubic meter), and the fifth temperature is 15 degrees centigrade and larger than the maximum value (10 degrees centigrade) of the preset temperature range (0 degrees centigrade to 10 degrees centigrade), in this case, both the humidity and the temperature in the refrigeration equipment 10 are abnormal, and in practical application, for the goods in the refrigeration equipment 10, the priority of temperature control is larger than that of humidity control, so the control device 11 controls the heater 14 and the fan 16 to stop operating, and controls the compressor 13 to start operating.

S704, the control device 11 receives the sixth humidity and the sixth temperature detected by the temperature/humidity sensor 12 at the sixth time.

Wherein the sixth humidity is the humidity inside the refrigeration apparatus 10 at the sixth moment. The sixth temperature is the temperature inside the refrigerator 10 at the sixth timing. The sixth time is a time after the fifth time.

S705, the control device 11 determines whether the sixth humidity detected by the temperature and humidity sensor 12 is smaller than the first humidity threshold, and whether the sixth temperature is within a preset temperature range.

The control device 11 controls the heater 14 and the fan 16 to stop operating, and the temperature in the refrigerator 10 gradually decreases after the compressor 13 starts operating. In order to prevent the temperature in the refrigeration apparatus 10 from decreasing too fast and further affecting the articles stored in the refrigeration apparatus 10, the control device 11 needs to receive the sixth temperature detected by the temperature and humidity sensor 12 at the sixth time, and then determine whether the sixth humidity detected by the temperature and humidity sensor 12 is smaller than the first humidity threshold, and whether the sixth temperature is within the preset temperature range. If the control device 11 determines that the sixth humidity detected by the temperature and humidity sensor 12 is smaller than the first humidity threshold and the sixth temperature is within the preset temperature range, S706 is executed. Otherwise, S704 is executed.

And S706, the control device 11 controls the compressor 13 to stop running and controls the heater 14 and the fan 16 to start running.

When the control device 11 determines that the sixth humidity detected by the temperature and humidity sensor 12 is smaller than the first humidity threshold value and the sixth temperature is within the preset temperature range, under the condition, the humidity in the refrigeration equipment 10 is abnormal, the temperature is normal, the control device 11 only needs to humidify the refrigeration equipment 10 without cooling, the compressor 13 does not need to input cold air for the evaporator 15, and the control device 11 controls the compressor 13 to stop running. Since the sixth humidity is less than the first humidity threshold, the control device 11 controls the heater 14 and the fan 16 to start operation, and the humidification process is continuously performed.

Alternatively, the control device 11 may control the heater 14 and the fan 16 to start operation while the compressor 13 stops operating; alternatively, the compressor 13 may be controlled to stop operation, and then the heater 14 and the fan 16 may be controlled to start operation. The embodiments of the present application do not limit this.

Illustratively, the control device 11 is controlled at 10: 20, determining that the sixth humidity detected by the temperature and humidity sensor 12 is 0.6 g/cubic meter and is smaller than the first humidity threshold (1 g/cubic meter), and the sixth temperature is 8 ℃, and when the sixth temperature is within a preset temperature range (0-10 ℃), under the condition, the humidity in the refrigeration equipment 10 is abnormal, the temperature is normal, the control device 11 only needs to humidify the refrigeration equipment 10, and does not need to cool, and then the compressor 13 is controlled to stop running, and the heater 14 and the fan 16 are controlled to start running.
