Referring to fig. 2, the fan control method of the ice cream machine 100 according to the embodiment of the present invention is used for controlling the rotation speed of the fan 170 according to the temperature of the refrigerant at the outlet of the condenser 150 and the ambient temperature of the space where the condenser 150 is located, so as to improve the cooling efficiency of the fan 170 on the condenser 150 and save more power. The method for controlling the fan 170 of the ice cream machine 100 comprises the following steps:
s100, acquiring the temperature of a refrigerant at the outlet of the condenser 150 and the ambient temperature of the space where the condenser 150 is located;
the temperature of the refrigerant at the outlet of the condenser 150 is directly or indirectly measured by the first temperature sensor 181. And the ambient temperature of the space where the condenser 150 is located is detected by the second temperature sensor 183.
And S300, controlling the rotating speed of the fan 170 according to the refrigerant temperature and the environment temperature.
In this embodiment, the temperature of the refrigerant at the outlet of the condenser 150 and the ambient temperature in the space of the condenser 150 are obtained, and then the rotation speed of the fan 170 is controlled according to the temperature of the refrigerant and the ambient temperature, so that the cooling efficiency of the fan 170 to the condenser 150 can be improved and more electricity can be saved.
Referring to fig. 3, fig. 4, fig. 5, fig. 6 and fig. 7, wherein the step S300 includes the following steps:
referring to fig. 3, in the sub-step S311, it is determined whether the refrigerant temperature is lower than a first preset refrigerant temperature and whether the ambient temperature is higher than a first preset ambient temperature;
s312, if the refrigerant temperature is lower than the first preset refrigerant temperature and the ambient temperature is higher than the first preset ambient temperature, the fan 170 is controlled to operate at a first preset rotation speed.
It can be understood that the condition that the refrigerant temperature is lower than the first preset refrigerant temperature and the ambient temperature is higher than the first preset ambient temperature indicates that the ambient temperature of the condenser 150 is higher, but the temperature of the cold coal at the outlet of the condenser 150 is normal, but the heat exchange of the condenser 150 is affected because the ambient temperature is continuously higher.
In the embodiment, the fan 170 is controlled to operate at the first preset rotating speed when the temperature of the refrigerant is less than the first preset temperature of the refrigerant and the ambient temperature is greater than the first preset temperature of the refrigerant, so that the fan 170 is used for dissipating heat for the condenser 150, the system refrigerating capacity of the cold coal loop is gradually increased, the refrigerant pressures of a high-pressure pipeline and a low-pressure pipeline of the refrigerating system are reduced, the stable change of the refrigerating system is ensured, the evaporating pressure is increased, and the compressor 110 is prevented from dewing and condensing condensate water. It is also possible to prevent the fan 170 from being out of operation for a long time, resulting in an excessively high system pressure and damage to the compressor 110.
In this embodiment, the first predetermined refrigerant temperature is 28 ℃ and the first predetermined ambient temperature is 25 ℃. The first predetermined speed is 60% of the rated speed of the fan 170.
In other embodiments of the present application, the first preset coal cooling temperature, the first preset ambient temperature, and the first preset rotating speed may also be preset according to a usage scenario of the ice cream machine 100.
Referring to fig. 4, in the substep S321, it is determined that the temperature of the cooling coal is greater than or equal to the first preset refrigerant temperature and less than the second preset refrigerant temperature;
in the substep S322, if the temperature of the cooling coal is greater than or equal to the first preset coolant temperature and the coolant temperature is less than the second preset coolant temperature, the fan 170 is controlled to operate at a second preset rotation speed, which is less than the first preset rotation speed.
It should be noted that the temperature of the cooling coal is greater than or equal to the first preset refrigerant temperature, and the temperature of the refrigerant is less than the second preset refrigerant temperature, which indicates that the temperature of the refrigerant is slightly higher.
Because the second preset rotating speed is set to be less than the first preset rotating speed under the given condition, electric energy can be saved under the condition that normal operation can be guaranteed. The fan 170 dissipates heat to the condenser 150 at a second preset rotation speed, so that the cooling capacity of the cooling medium loop is gradually increased, and the cooling medium pressures of the high-pressure pipeline and the low-pressure pipeline of the refrigeration system are reduced, thereby ensuring the stable change of the refrigeration system. Meanwhile, evaporation pressure is increased, condensation of the compressor 110 is prevented, and condensate water is prevented from being serious.
In this embodiment, the second predetermined refrigerant temperature is 30 ℃. The second preset rotation speed is 40% of the rated rotation speed.
Of course, in other embodiments of the present application, the second predetermined refrigerant temperature and the second predetermined rotation speed may also be adjusted according to the actual use of the ice cream machine 100.
Referring to fig. 5, in the substep S331, it is determined whether the temperature of the cold coal is greater than or equal to a second preset refrigerant temperature and less than a third preset refrigerant temperature;
it should be noted that when the refrigerant temperature output liquid is greater than or equal to the second refrigerant preset temperature and less than the third refrigerant preset temperature, it indicates that the temperature of the condenser 150 is higher.
In the substep S332, if the temperature of the cold coal is greater than or equal to the second preset refrigerant temperature and the refrigerant temperature is less than a third preset refrigerant temperature, the fan 170 is controlled to operate at a third preset rotation speed, where the third preset rotation speed is greater than the second preset rotation speed.
In this embodiment, when the refrigerant temperature is greater than or equal to the preset temperature of the second refrigerant and less than the preset temperature of the third refrigerant, the fan 170 operates at the third preset rotation speed, so as to increase heat dissipation for the condenser 150, further increase the refrigerating capacity in the refrigerant loop, reduce the refrigerant pressure of the high-pressure pipeline and the low-pressure pipeline of the refrigeration system, and ensure stable change of the refrigeration system. While increasing the evaporation pressure to prevent the compressor 110 from dewing and condensing the condensed water.
In this embodiment, the third predetermined refrigerant temperature is 30 ℃. The third preset rotating speed is equal to the first preset rotating speed, and the third preset rotating speed is 60% of the rated rotating speed of the fan 170.
Of course, in other embodiments of the present application, the third preset refrigerant temperature and the third preset rotation speed can also be adjusted according to the actual use of the ice cream machine 100.
Referring to fig. 6, in the sub-step S341, it is determined that the refrigerant temperature is greater than or equal to a third preset refrigerant temperature;
when the temperature of the coolant is equal to or higher than the third predetermined coolant temperature, the temperature of the condenser 150 is high.
In the substep S342, if the refrigerant temperature is greater than or equal to the third preset refrigerant temperature, the fan 170 is controlled to operate at a fourth preset rotation speed, where the fourth preset rotation speed is greater than the third preset rotation speed.
The fourth preset rotation speed is 100% of the rated rotation speed in the present embodiment. When the fan 170 is operated at full speed, heat is dissipated from the condenser 150, the refrigerating capacity of the system is maximized, and the refrigerant pressures of the high-pressure pipeline and the low-pressure pipeline of the refrigerating system are further reduced, so that stable change of the refrigerating system is ensured.
Referring to fig. 7, in the sub-step S351, it is determined whether the refrigerant temperature is lower than a first predetermined refrigerant temperature and the ambient temperature is lower than a first predetermined ambient temperature;
in this interval, it is indicated that both the condenser 150 temperature and the ambient temperature are low.
In the substep S352, when the refrigerant temperature is lower than a first preset refrigerant temperature and the ambient temperature is lower than the first preset ambient temperature, the fan 170 is controlled to operate at a fifth preset rotation speed, where the fifth preset rotation speed is lower than the first preset rotation speed.
In the present embodiment, the fifth preset rotation speed is 50% of the rated rotation speed.
In this embodiment, the step S100 and the step S300 further include the steps of:
step S200, judging whether the ambient temperature and the refrigerant temperature are obtained within a preset time;
in the substep S500, if the ambient temperature and the refrigerant temperature are not obtained within the preset time, the fan 170 is controlled to operate at a sixth preset rotation speed.
If the ambient temperature and the refrigerant temperature are obtained within the preset time, the fan 170 is controlled to perform the substeps of S300 and S300.
Since the refrigerant temperature and the ambient temperature are detected by the first temperature sensor 181 and the second temperature sensor 183, the service life and the installation condition of the sensors are limited, so that the damage to the compressor 110 is avoided under the condition that the sensors are damaged or not connected, and the fan 170 is operated at the sixth preset rotating speed under the condition that the refrigerant temperature and the ambient temperature cannot be detected.
In the present embodiment, the sixth preset rotation speed is 60% of the rated rotation speed of the fan 170.

It should be noted that the basic principle and the generated technical effects of the fan control device provided by the embodiment are substantially the same as those of the embodiment, and for the sake of brief description, no mention is made in part of this embodiment, and reference may be made to corresponding contents in the embodiment.
Referring to fig. 8, the fan control apparatus 300 includes a first obtaining module 310, a second obtaining module 330, and a control module 350.
