The present invention also provides a method for controlling a refrigeration apparatus, and referring to fig. 3, fig. 1 is a schematic flow chart of a first embodiment of the method for controlling a refrigeration apparatus according to the present invention, and the method includes:
step S10, acquiring a currently set humidity mode and a first humidity of the humidity control space;
in this embodiment, the humidity mode refers to a humidity level set by a user for the humidity control space according to the user's own needs, and the humidity mode may include a high humidity mode and a low humidity mode, where high humidity and low humidity are relatively related, and a humidity range corresponding to each mode may be a default of the system or may be set by the user, and it should be noted that the humidity mode may also be relative to a set humidity threshold, for example, the high humidity mode is set to be higher than 20% humidity, and the low humidity mode is set to be lower than 30% humidity; it is also possible to set a plurality of hierarchical humidity modes, such as a high humidity mode, a middle humidity mode, and a low humidity mode, or define a humidity mode by a specific humidity value interval, such as a 0% to 20% humidity mode, a 20% to 40% humidity mode, a 40% to 60% humidity mode, and the like, wherein the 0% to 20% humidity mode, the 20% to 40% humidity mode are the low humidity mode, and the 40% to 60% humidity mode are the high humidity mode. The first humidity of the humidity control space refers to the real-time humidity of the current humidity control space, and is measured by a humidity sensor arranged in the humidity control space in the embodiment.
Step S20, judging whether the first humidity is smaller than a first preset humidity threshold corresponding to the high humidity mode, wherein the humidity mode is a high humidity mode;
when the humidity mode is a high humidity mode, the humidity in the humidity control space is required to be kept in a relatively high humidity range, wherein the range can be higher than a certain humidity value, and when judging whether the humidity in the humidity control space meets the requirement of the high humidity mode, the humidity value is directly used as a first preset humidity threshold value for judgment; the range can also be a humidity range, and when judging whether the humidity in the humidity control space meets the requirement of the high humidity mode, the smaller endpoint value of the range is used as a first preset humidity threshold value for judgment.
Step S30, acquiring the working state of the compressor when the first humidity is smaller than a first preset humidity threshold corresponding to the high-humidity mode, and judging whether the compressor is in a shutdown state;
if not, no processing is carried out.
If the first humidity is smaller than a first preset humidity threshold corresponding to the high humidity mode, it indicates that the humidity of the current humidity control space does not meet the high humidity requirement, and therefore, humidification operation is required. Can blow in the wet space of accuse with outside air through the evaporimeter through the fan, carry out heat exchange with frosting on the evaporimeter for frosting part is frosted, and brings into the humidity in the space of accuse wet space in order to improve the humidity of accuse wet space through the wind channel with the moisture that the frost obtained. In another embodiment, the evaporator bin is communicated with the humidity control space through two independent air channels, the humidifying operation is that high-temperature air in the humidity control space enters the evaporator bin through one air channel to exchange heat with frosting on the evaporator, so that frosted parts are partially defrosted, and moisture obtained by defrosting is brought into the humidity control space through the other air channel to improve the humidity of the humidity control space. Because the surface temperature of the evaporator is very low when the refrigeration system is in a working state, the high-temperature air in the humidity control space enters the evaporator bin through the air duct at the moment, and the frosting on the surface of the evaporator cannot be caused, the humidifying operation needs to be carried out in a non-working state of the refrigeration system, and whether the refrigeration system is in a working state can be judged by judging whether the compressor is in a shutdown state.
And step S40, the compressor is in a stop state, and the first air door and the fan are opened.
The compressor is in a starting state and is not processed.
When the compressor is in a shutdown state, the humidification operation can be started, the first air door, the fan and the compensation heating wire are opened, air among the storage chamber, the humidity control space, the air channel and the evaporator bin starts to flow circularly under the action of the fan, high-temperature air in the humidity control space enters the evaporator bin from the air channel and exchanges heat with frosting on the evaporator, so that the frosted part is frosted, and moisture obtained by defrosting is brought into the humidity control space through the air channel, so that the humidity of the humidity control space is improved.
In the embodiment, by arranging the air duct, when humidification operation is needed, the air duct conveys air with higher relative temperature in the humidity control space to the evaporator in the evaporator bin by opening the fan and the first air door, and exchanges heat with the evaporator, so that frost is formed and defrosted on the evaporator, and moisture obtained by defrosting is conveyed to the humidity control space again to increase the humidity in the humidity control space.
Further, referring to fig. 4, in the second embodiment of the control method of the refrigeration apparatus of the present invention proposed based on the first embodiment of the present invention, after the step S40, the steps of:
step S50, acquiring a first temperature of the humidity control space, and judging whether the first temperature is less than or equal to a preset temperature threshold value;
and step S51, the first temperature is less than or equal to a preset temperature threshold, and the compensation heating wire is started.
And if the first temperature is greater than the preset temperature threshold, no treatment is carried out.
In this embodiment, the preset temperature threshold is 0 ℃.
Carry the evaporimeter department in the evaporimeter storehouse along with the higher air of relative temperature in the accuse wet space, with the evaporimeter carries out heat exchange for frosting on the evaporimeter changes the frost, and will change the moisture that the frost obtained and carry in the accuse wet space, the temperature in the accuse wet space can be lower and lower, and when the temperature in the accuse wet space is less than or equal to 0 degree centigrade, the air that the evaporimeter storehouse was carried in the accuse wet space can't make the frosting on the evaporimeter change, consequently when detecting the temperature in the accuse wet space and be less than 0 degree centigrade, opens the compensation heater strip, improves the temperature of the air through return air duct, makes the air of carrying the evaporimeter storehouse can make the frosting on the evaporimeter change the frost. It should be noted that the preset temperature threshold may be set to different values, and if the humidity needs to be increased faster, the preset temperature threshold may be set to a higher value. Further, the compensation heating wire can be directly started when the first air door and the fan are controlled to be opened.
In this embodiment, the compensation heating wire is arranged on the return air duct, and the compensation heating wire is turned on when the first temperature of the humidity control space is less than or equal to the preset temperature threshold value, so that it can be ensured that the high-temperature air entering the evaporator bin frosts on the evaporator.
Further, referring to fig. 5, in the third embodiment of the control method of the refrigeration apparatus of the present invention proposed based on the first embodiment of the present invention, after the step S51, the steps of:
step S60, acquiring a second humidity of the humidity control space, and determining whether the second humidity is greater than or equal to a second preset humidity threshold, where the second humidity threshold is greater than or equal to the first humidity threshold;
and step S61, the second humidity is greater than or equal to the second preset humidity threshold, and the first air door, the fan and the compensation heating wire are closed.
In order to avoid that the humidity in the humidity control space is too high to cause the storage of the articles in the humidity control space, a second humidity threshold value is set, and when the second humidity in the humidity control space is greater than or equal to the second preset humidity threshold value, the first air door, the fan and the compensation heating wire can be controlled to be closed.
