[0031] The optional embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] Example 1

[0033] Traditional refrigeration systems usually consist of two parts: an air cooler and a condenser. The air cooler is responsible for air processing and air supply, while the condenser is responsible for refrigerant compression and heat dissipation. However, this split design has problems such as complex installation and large space occupation. Therefore, the integrated chiller (abbreviated as integrated chiller) system components are integrated to solve the problems of complex installation and large space occupation of traditional refrigeration units.

[0034] In a preferred embodiment 1 of the present invention, a control method for an integrated refrigerator is provided. The control method can be directly applied to the integrated refrigerator. Specifically, Figure 1 An optional structural schematic diagram of the integrated refrigerator is shown, such as Figure 1 As shown, the integrated refrigerator has an integrated upper and lower structure with internal and external units connected by a foam layer to prevent cooling loss and heat transfer. The evaporator 1 and the inner surface of the insulation layer are located indoors, and the condenser 2 and the outer surface of the insulation layer are located outdoors. The insulation layer can be a foam board 4, located between the evaporator 1 and the condenser 2, and connected to the wall or partition between the indoor and outdoor. Figure 1 As shown, at least a condensing fan 3 is included.

[0035] In addition, as people's requirements for indoor air quality increase, fresh air systems have gradually become standard in homes and offices. However, existing fresh air systems are usually independent of refrigeration systems, resulting in equipment redundancy and increased energy consumption. Figure 1 The integrated refrigerator shown has a fresh air valve 7 and a fresh air pipe 8, which reduces the number of devices, saves installation space, and makes installation simpler and faster. At the same time, the integrated fresh air system can effectively prevent condensation on the insulation layer of the integrated refrigerator.

[0036] The integrated refrigerator also includes: a temperature sensor: respectively installed on the inner surface 5 and the outer surface 6 of the foam plate 4, for detecting the temperature of the inner and outer surfaces; a temperature and humidity sensor: installed in the use environment, such as a cold storage, for detecting the ambient temperature and humidity inside and outside the cold storage; a controller: receiving data from the temperature sensor and the humidity sensor, calculating the dew point temperature, reading the operating status of the unit, and controlling the action of the decondensation removal system according to whether the inner and outer surface temperatures are lower than the dew point temperature.

[0037] Based on the above-mentioned integrated refrigerator, a preferred embodiment 1 of the present invention provides an integrated refrigerator control method, Figure 2 An optional flow chart of the method is shown as follows: Figure 2 As shown, the method includes the following steps S202-S206:

[0038] S202: Check whether there is condensation risk on the outer surface and the inner surface of the insulation layer;

[0039] S204: When there is a risk of condensation on the outer surface of the insulation layer, decondensation control is performed through the fresh air system and the evaporator;

[0040] S206: When there is a risk of condensation on the inner surface of the insulation layer, decondensation control is performed through a condenser.

[0041] In the above implementation, an integrated refrigerator control solution is provided. When the risk of condensation is detected on the outer surface of the insulation layer, decondensation control is performed through the fresh air system and the evaporator; when the risk of condensation is detected on the inner surface of the insulation layer, decondensation control is performed through the condenser. Through the above detection and corresponding control solution, the condensation phenomenon on the insulation layer is effectively reduced, and the problem of poor insulation effect and damaged insulation performance of the insulation layer due to condensation is solved, and the anti-condensation effect of the insulation layer, the operating efficiency and service life of the integrated refrigerator are improved.

[0042] In a preferred embodiment of the present invention, detecting whether there is a condensation risk on the outer surface and the inner surface of the insulation layer includes: calculating the outdoor air dew point temperature and the indoor air dew point temperature; detecting the outdoor temperature and the indoor temperature, determining whether there is a condensation risk on the outer surface of the insulation layer according to the outdoor air dew point temperature and the outdoor temperature, and determining whether there is a condensation risk on the inner surface of the insulation layer according to the indoor air dew point temperature and the indoor temperature; wherein, when the outdoor temperature is less than or equal to the outdoor air dew point temperature, it is determined that there is a condensation risk on the outer surface of the insulation layer, and when the indoor temperature is less than or equal to the indoor air dew point temperature, it is determined that there is a condensation risk on the inner surface of the insulation layer. When the temperature of the inner surface of the foam board is less than or equal to the dew point temperature, the inner surface has a condensation risk, and if the temperature of the outer surface of the foam board is less than or equal to the dew point temperature, it means that there is a condensation risk on the outer surface. The temperature of the inner and outer surfaces of the foam board, the temperature and humidity of the environment inside and outside the cold storage are detected by sensors, and the dew point temperature of the air is calculated. By real-time detection of the outdoor air dew point temperature and outdoor temperature, it is determined whether there is a condensation risk on the outer surface of the insulation layer, and the indoor air dew point temperature and indoor temperature are used to determine whether there is a condensation risk on the inner surface of the insulation layer, and then subsequent anti-condensation control is performed to avoid condensation and the losses caused by it in time.

[0043] When it is determined that there is a risk of condensation on the inner surface of the insulation layer, decondensation control is performed through the fresh air system and evaporator, including: detecting the indoor humidity, judging the condensation level on the inner surface of the insulation layer according to the indoor humidity; controlling the fresh air system to perform decondensation control according to the condensation level on the inner surface of the insulation layer. When the temperature of the inner surface of the foam board is less than or equal to the dew point temperature, there is a risk of condensation on the inner surface, and then judging whether the cold storage is currently in a high humidity or low humidity state through the humidity sensor data. The indoor humidity is used to further distinguish whether the room is in a high humidity or low humidity state. High humidity and low humidity correspond to different condensation levels, and then the corresponding anti-condensation control is performed to achieve precise anti-condensation control.

[0044] Specifically, the condensation level on the inner surface of the insulation layer includes at least a slight condensation level and a severe condensation level; the condensation level on the inner surface of the insulation layer is determined according to the indoor humidity, including: when the indoor humidity is less than or equal to the preset humidity, the condensation level on the inner surface of the insulation layer is determined to be a slight condensation level; when the indoor humidity is greater than the preset humidity, the condensation level on the inner surface of the insulation layer is determined to be a severe condensation level. When the indoor humidity is less than or equal to the preset humidity, that is, the indoor temperature is high and the humidity is low, the condensation level on the inner surface of the insulation layer is determined to be a slight condensation level. When the indoor humidity is greater than the preset humidity, that is, the indoor temperature is high and the humidity is high, the condensation level on the inner surface of the insulation layer is determined to be a severe condensation level, which is a situation where condensation is extremely likely to occur, and therefore a more effective anti-condensation control is required.

[0045] After determining the condensation level on the inner surface of the insulation layer, the fresh air system and the evaporator are controlled to perform condensation removal control according to the condensation level on the inner surface of the insulation layer, including: when the condensation level on the inner surface of the insulation layer is a slight condensation level, the fresh air valve of the fresh air system is controlled to open to a first preset opening, and the evaporator is controlled to increase the indoor temperature; when the condensation level on the inner surface of the insulation layer is a severe condensation level, the fresh air valve of the fresh air system is controlled to open to a second preset opening, and the evaporator is controlled to increase the indoor temperature; wherein the second preset opening is greater than the first preset opening. Condensation is removed by introducing fresh air, and the humidity in the warehouse is comprehensively considered and the temperature in the warehouse is appropriately increased within a reasonable operating temperature range, so that the dew point temperature is lower than the surface temperature of the foam board, and no condensation occurs. If the humidity is high, the angle of the fresh air valve is adjusted to introduce a larger amount of fresh air; if the humidity is low, the angle of the fresh air valve is adjusted to introduce a smaller amount of fresh air.

[0046] When it is determined that there is a risk of condensation on the outer surface of the insulation layer, the condenser is used for decondensation control, including: detecting the indoor temperature and outdoor temperature, calculating the indoor and outdoor temperature difference; judging the condensation level on the outer surface of the insulation layer according to the indoor and outdoor temperature difference, and controlling the condenser for decondensation control according to the condensation level on the outer surface of the insulation layer. If the temperature of the outer surface of the foam board is less than or equal to the dew point temperature, it means that there is a risk of condensation on the outer surface. The condensation level is judged by the internal and external temperature difference, and the corresponding anti-condensation control is executed to remove condensation in a targeted manner, achieve accurate anti-condensation control, and improve the anti-condensation effect.

[0047] The condensation level on the outer surface of the insulation layer includes at least a slight condensation level, a moderate condensation level and a severe condensation level; the condensation level on the outer surface of the insulation layer is determined according to the indoor and outdoor temperature difference, and the condenser is controlled to perform decondensation control according to the condensation level on the outer surface of the insulation layer, including: when the indoor and outdoor temperature difference is less than or equal to the first preset temperature difference, the condensation level on the inner surface of the insulation layer is determined to be a slight condensation level, and the condensation fan is controlled to operate at a low speed; when the indoor and outdoor temperature difference is greater than the first preset temperature difference and less than or equal to the second preset temperature difference, the condensation level on the inner surface of the insulation layer is determined to be a moderate condensation level, and the condensation fan is controlled to operate at a medium speed; when the indoor and outdoor temperature difference is greater than the second preset temperature difference, the condensation level on the inner surface of the insulation layer is determined to be a severe condensation level, and the condensation fan is controlled to operate at a high speed; wherein the second preset temperature difference is greater than the first preset temperature difference. The greater the indoor and outdoor temperature difference, the greater the condensation risk, and vice versa. When the risk of condensation is high, the condensing fan is controlled to run at high speed. When the risk of condensation is low, the condensing fan is controlled to run at medium or low speed to speed up the air flow on the outer surface, remove condensation, make the dew point temperature lower than the surface temperature of the foam board, and no condensation will occur.

[0048] In another preferred embodiment of the present invention, before detecting whether there is a condensation risk on the outer surface of the insulation layer and the inner surface of the insulation layer, it also includes: detecting the indoor thermal insulation effect; wherein the indoor thermal insulation effect at least includes poor indoor thermal insulation effect and good indoor thermal insulation effect; when the indoor thermal insulation effect is poor, triggering the detection of whether there is a condensation risk on the outer surface of the insulation layer and the inner surface of the insulation layer, and when there is no condensation risk on the outer surface of the insulation layer and the inner surface of the insulation layer, an alarm reminder is issued to remind the user to detect the indoor sealing and the door switch; when the indoor thermal insulation effect is good, the current operating state of the integrated refrigerator is kept unchanged. Specifically, detecting the indoor thermal insulation effect includes: obtaining the operating state of the integrated refrigerator; wherein the operating state includes at least: the operating time of the integrated refrigerator and the start-stop interval of the compressor; when the operating time of the integrated refrigerator is greater than the preset time, or the start-stop interval of the compressor is less than the preset interval, it is determined that the indoor thermal insulation effect is poor, otherwise, it is determined that the indoor thermal insulation effect is good.

[0049] When the integrated refrigeration machine is running, the operating status of the refrigeration machine, the operating time of the compressor, and the start-stop interval are recorded in real time. When the refrigeration effect of the cold storage is poor, the operating time of the unit is abnormal, or the compressor is frequently started and stopped, it means that the insulation effect of the cold storage is not good, which may be caused by condensation on the foam board or other reasons. When the temperature of the inner surface of the foam board is greater than the dew point temperature, it means that there is no condensation on the inner surface, which may be caused by condensation on the outer surface or other reasons. Then check whether the temperature of the outer surface of the foam board is less than or equal to the dew point temperature. If the outer surface is not less than or equal to the dew point temperature, it means that there is no condensation inside and outside the foam board. It may be that the sealing of other parts of the cold storage is poor, the door is not closed, or other objective reasons cause the integrated machine to operate abnormally.

[0050] Another integrated refrigerator control method is provided in the preferred embodiment 1 of the present invention. Specifically, Figure 3 An optional flow chart of the method is shown as follows: Figure 3 As shown, the method includes the following steps S301-S320:

[0051] S301: Start;

[0052] S302: Read the operating status of the integrated machine and record the operating time and start / stop interval of the compressor;

[0053] S303: Determine whether the compressor is frequently started and stopped, and the cooling effect is poor. If yes, proceed to step S304; otherwise, proceed to step S312;

[0054] S304: Monitor the temperature of the foam board surface of the integrated machine and the temperature and humidity inside and outside the cold storage, and calculate the dew point temperature in real time;

[0055] S305: The inner surface temperature of the foaming board is less than or equal to the dew point temperature. If yes, proceed to step S307; otherwise, proceed to step S306;

[0056] S306: Send out an alarm prompt and check whether other parts of the cold storage are poorly sealed, whether the door is opened frequently or not closed;

[0057] S307: Determine whether the humidity is higher than the set value, if yes, proceed to step S308, otherwise proceed to step S310;

[0058] S308: The cold storage is in a low temperature and high humidity state, which is a serious condensation risk;

[0059] S309: Control the fresh air valve to open at a large angle to introduce fresh air, neutralize the humidity in the warehouse, and appropriately increase the temperature in the warehouse within a reasonable range;

[0060] S310: The cold storage is in a low temperature and low humidity state, with a slight condensation risk;

[0061] S311: Control the fresh air valve to open at a small angle to introduce fresh air, neutralize the humidity in the warehouse, and appropriately increase the temperature in the warehouse within a reasonable range;

[0062] S312: The outer surface temperature of the foaming board is less than or equal to the dew point temperature. If yes, proceed to step S314; otherwise, proceed to step S313;

[0063] S313: Send out an alarm prompt and check whether other parts of the cold storage are poorly sealed, whether the door is opened frequently or not closed;

[0064] S314: Calculate the temperature difference between the indoor and outdoor of the cold storage and compare it with the set temperature difference;

[0065] S315: If the indoor and outdoor temperature difference is much greater than the set temperature difference, there is a serious condensation risk;

[0066] S316: Control the condensing fan to run at a high speed to speed up the removal of condensation;

[0067] S317: If the indoor and outdoor temperature difference is slightly greater than the set temperature, there is a moderate condensation risk;

[0068] S318: Control the condensing fan to run at medium speed to speed up the removal of condensation;

[0069] S319: If the indoor and outdoor temperature difference is less than the set temperature difference, there is a slight condensation risk;

[0070] S320: Control the condensing fan to run at a low speed to speed up the removal of condensation.

[0071] When the integrated refrigeration machine is running, the operating status of the refrigeration machine, the operating time of the compressor, and the start-stop interval are recorded in real time. When the refrigeration effect of the cold storage is poor, the operating time of the unit is abnormal, or the compressor is frequently started and stopped, it means that the insulation effect of the cold storage is not good, which may be caused by condensation on the foam board or other reasons. The sensor detects the temperature of the inner and outer surfaces of the foam board, the temperature and humidity of the environment inside and outside the cold storage, and calculates the dew point temperature of the air. When the temperature of the inner surface of the foam board is less than or equal to the dew point temperature, there is a risk of condensation on the inner surface. Then, through the humidity sensor data, it is determined whether the cold storage is currently in a high humidity or low humidity state. Condensation is removed by introducing fresh air, and the humidity in the warehouse is comprehensively considered and the temperature in the warehouse is appropriately increased within a reasonable operating temperature range, so that the dew point temperature is lower than the surface temperature of the foam board, and no condensation occurs. If the humidity is high, adjust the angle of the fresh air valve to introduce a larger amount of fresh air. If the humidity is low, adjust the angle of the fresh air valve to introduce a smaller amount of fresh air.

[0072] When the temperature of the inner surface of the foam board is greater than the dew point temperature, it means that there is no condensation on the inner surface. It may be caused by condensation on the outer surface or other reasons. Then check whether the temperature of the outer surface of the foam board is less than or equal to the dew point temperature. If the outer surface is not less than or equal to the dew point temperature, it means that there is no condensation inside and outside the foam board. It may be that the sealing of other parts of the cold storage is poor, the door is not closed, or other objective reasons cause the abnormal operation of the integrated machine. If the temperature of the outer surface of the foam board is less than or equal to the dew point temperature, it means that there is a risk of condensation on the outer surface. The level of condensation is judged by the temperature difference between the inside and outside. The greater the temperature difference between indoor and outdoor, the greater the condensation risk. Conversely, the condensation risk is relatively small. When the condensation risk is large, the condensation fan is controlled to run at high speed. When the condensation risk is small, the condensation fan is controlled to run at medium or low speed to speed up the air flow on the outer surface and remove condensation, so that the dew point temperature is lower than the surface temperature of the foam board, and no condensation occurs.
