It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Fig. 1 is a schematic method diagram of an embodiment of a method for controlling a refrigeration storage device provided by the invention. The refrigeration storage equipment comprises a refrigerator and/or an ice chest.

As shown in fig. 1, according to an embodiment of the present invention, the method for controlling a refrigeration storage device includes at least steps S110, S130 and S140.

Step S110, after the refrigeration storage equipment is powered on and operated, detecting the environment temperature of the environment where the refrigeration storage equipment is located and/or the door opening condition of the refrigeration storage equipment.

Specifically, the ambient temperature is detected by a temperature sensor. The door opening condition specifically comprises single door opening time, accumulated door opening time and/or door opening times. The method comprises the steps that any door of the refrigeration and storage equipment is detected to be opened until all doors of the refrigeration and storage equipment are detected to be closed, namely, the door is opened once; and when any door of the refrigeration storage equipment is detected to be opened, timing is started until all doors of the refrigeration storage equipment are detected to be closed, and the timing is finished and is the single-time door opening time.

And step S130, judging whether the environment temperature and/or the door opening condition meet preset conditions.

The preset condition is a judgment condition for judging whether the refrigerating and storing equipment runs in a first control mode. The preset condition may specifically include at least one of the following conditions: whether the environment temperature is larger than or equal to a preset temperature value or not, whether the single door opening time of the refrigeration storage equipment is larger than a first preset time or not, whether the door opening times of the refrigeration storage equipment are larger than preset times or not, and whether the accumulated door opening time of the refrigeration storage equipment is larger than a second preset time or not. Wherein the predetermined temperature value is, for example, 34 ℃; the first predetermined time may be, for example, 70 seconds; the predetermined number of times may be, for example, 3 times; the second predetermined time may be, for example, 90 seconds.

And S180, if the environment temperature and/or the door opening condition are judged not to meet the preset condition, the refrigeration storage equipment is operated in a first control mode.

Specifically, when the refrigeration and storage equipment is powered on and operated, the refrigeration and storage equipment is operated in a second control mode. The second control mode is specifically a normal control mode, namely a conventional control mode of the refrigeration and storage equipment. And if the environment temperature and/or the door opening condition are judged not to meet the preset condition, the refrigeration storage equipment is operated in a first control mode. Further, as shown in fig. 1, a step S190 may be further included, where if it is determined that the ambient temperature and/or the door opening condition meet the preset condition, the refrigeration storage device continues to operate in a second control mode, that is, the refrigeration storage device keeps operating in a normal control mode, and meanwhile, the door opening times of the refrigeration storage device may be cleared, and the accumulated door opening time is cleared.

The first control mode is specifically a reduced power consumption mode. The operating the refrigeration storage device in the first control mode may specifically include: the starting temperature of the compressor is improved, the starting frequency of the compressor is reduced, the frequency rising time of the compressor is prolonged, and/or the rotating speed of the refrigerating fan is reduced.

Specifically, the compressor starting temperature may specifically include a compressor starting temperature corresponding to a refrigerating chamber of the refrigeration storage device and/or a compressor starting temperature corresponding to a freezing chamber of the refrigeration storage device, and increasing the compressor starting temperature specifically includes: and increasing the starting temperature of the compressor corresponding to the refrigerating chamber of the refrigeration storage equipment by a first temperature value and/or increasing the starting temperature of the compressor corresponding to the freezing chamber of the refrigeration storage equipment by a second temperature value. The first temperature value and the second temperature value may be equal or unequal. For example, the starting temperature of the compressor corresponding to the refrigerating chamber and the starting temperature corresponding to the freezing chamber are respectively increased by M ℃, and the value of M is, for example, 1 ℃.

Reducing the starting frequency of the compressor may specifically include: reducing the starting frequency of the compressor by a first frequency value; increasing the up-conversion time of the compressor may specifically include: increasing an up-conversion time of the compressor by a first time value. And if the current starting frequency of the compressor is the lowest starting frequency, keeping the compressor at the lowest starting frequency.

The starting frequency may be, for example, a starting gear of the compressor, and specifically, more than one gear of the compressor may be preset, where each gear corresponds to a different compressor operating frequency, for example, the compressor operating frequency corresponding to 1 gear is 22Hz, the compressor operating frequency corresponding to 2 gear is 25Hz, and the compressor operating frequency corresponding to 3 gear is 30Hz … …. The first frequency value may be, for example, a preset number of gears. The frequency-up time may be, for example, a frequency-up time of the compressor, where, for example, the air conditioner is currently operated in a normal mode (second control mode), and a start gear of the normal mode is not a lowest gear, the start gear of the compressor is decreased from the start gear of the normal mode by a, a typical value a is 1 gear, the frequency-up time is increased by B, and the typical value B is 30 minutes, and if the start gear of the normal mode is a lowest gear, the operation of the lowest gear is maintained, the frequency-up time is increased by B, and the typical value B is 30 minutes.

The reducing of the rotational speed of the freezing fan may specifically include: and correspondingly adjusting the rotating speed of the refrigerating fan according to the current running frequency of the compressor after the starting frequency is reduced. For example, the rotating speed of the freezing fan is adjusted according to the current running gear after the starting gear is reduced, and when the compressor runs at 1 gear and 2 gears, the freezing fan runs at a low speed; when the compressor runs at 3 and 4 grades, the freezing fan runs at a medium speed; when the compressor is operated at a gear higher than 4 th, the freezing fan is operated at a high speed.

And step S120, setting the starting frequency and/or the frequency increasing time of the compressor of the refrigeration and storage equipment in a second control mode according to the environment temperature of the environment where the refrigeration and storage equipment is located and the temperature of each room of the refrigeration and storage equipment.

In one embodiment, the frequency of compressor activation may be determined based on the ambient temperature of the environment. Specifically, the reference frequency of the compressor is determined according to the environment temperature, and then the starting frequency of the compressor is determined according to the reference frequency, the temperature of each compartment of the refrigeration and storage equipment and the starting point temperature of the compressor corresponding to each compartment. The starting frequency may be, for example, a starting gear of the compressor; the reference frequency may be, for example, a reference gear of the compressor. The different environmental temperature ranges correspond to different reference gears, for example, when the environmental temperature is in a temperature range less than 12 ℃, the corresponding reference gear is gear 1, and when the environmental temperature is in a temperature range greater than or equal to 12 ℃ and less than 18 ℃, the corresponding reference gear is gear 2 … …; and subtracting the corresponding starting point temperature of the compressor from the room temperature to obtain a corresponding temperature difference, determining the maximum temperature difference between the room temperature and the corresponding starting point temperature of the compressor, and determining a starting gear of the compressor according to the maximum temperature difference, wherein the starting gear is equal to the sum of the ratio of the maximum temperature difference to a preset coefficient and the reference gear, for example, when the preset coefficient is 2 and the maximum temperature difference is 2 degrees, the starting gear is increased by 1 gear on the basis of the reference gear, when the temperature is 4 degrees, the starting gear is increased by 2 gears on the basis of the reference gear, and so on.

In one embodiment, the ramp-up time may be set according to an ambient temperature and a starting frequency of the compressor, and the ramp-up time may be, for example, a ramp-up time of the compressor. Different ambient temperature intervals and/or activation frequencies (e.g., starting gear) correspond to different upshift times, e.g., ambient temperature is in a temperature interval less than 12 ℃, upshift time is 60 minutes when current gear is 1 gear, and upshift time is 90 minutes … … when current gear is 2 gear.

As shown in fig. 3, according to another embodiment of the present invention, the method for controlling a refrigeration storage device further includes steps S140 and S150.

And step S140, judging whether the current control mode of the refrigeration storage equipment is a third control mode.

And S150, if the current control mode is judged to be the third control mode, enabling the refrigeration storage equipment to continuously operate in the third control mode.

Specifically, before the refrigeration and storage equipment is operated in the first control mode (step S180), whether the current control mode of the refrigeration and storage equipment is the third control mode or not is judged. The third control mode may specifically include a quick-cooling mode and/or a quick-freezing mode. If the current control mode of the refrigeration storage equipment is the third control mode, the fact that a user has special requirements on the refrigeration storage equipment, namely, quick cooling or quick freezing is indicated, at the moment, the refrigeration storage equipment is enabled to keep the third control mode to operate without operating in the control mode for reducing power consumption, meanwhile, the door opening times of the refrigeration storage equipment can be reset, and the accumulated door opening time is reset. If the current control mode is not the third control mode, the refrigeration storage equipment is operated in the first control mode (namely step S180).

Fig. 4 is a schematic method diagram of a refrigeration storage device control method according to still another embodiment of the invention. As shown in fig. 4, according to still another embodiment of the present invention, the method for controlling a refrigeration storage device further includes steps S160 and S170.

And step S160, judging whether the power-on operation time of the refrigeration storage equipment reaches a third preset time.

And step S170, if the power-on operation time does not reach the third preset time, enabling the refrigeration storage equipment to operate in a second control mode.

Specifically, the running time of the refrigeration storage device is timed when the refrigeration storage device is powered on, and before the refrigeration storage device is operated in the first control mode (step S180), whether the powered-on running time of the refrigeration storage device reaches a third preset time is judged. The third predetermined time may be, for example, 24 hours, and if it is determined that the power-on operation time does not reach the third predetermined time, the refrigeration storage device is kept to operate in the second control mode, and if it is determined that the power-on operation time reaches the third predetermined time, the refrigeration storage device is operated in the first control mode (i.e., step S180). If it is determined in the foregoing step S130 that the ambient temperature and/or the door opening condition satisfy the preset condition, the refrigeration storage device is operated in a second control mode (step S190), and the timing of the operation time is cleared.

In order to clearly illustrate the technical solution of the present invention, an implementation flow of the control method for a refrigeration storage device provided by the present invention is described below with an embodiment.
