Detailed Description
The technical solution is described in detail with reference to specific embodiments below.
As shown in fig. 1-7, the invention discloses a refrigeration device capable of automatically identifying quick-freezing requirements, taking a refrigerator as an example, when the refrigerator is in a conventional refrigeration state, a defrosting sensor of the refrigerator detects the real-time temperature of an evaporator of the refrigerator and transmits parameters to a main controller of the refrigerator, the main controller judges whether the evaporator is in an abnormal state or not according to the parameters transmitted by the defrosting sensor, if the real-time temperature of the evaporator is detected to be overhigh, the main controller judges that the evaporator is in a frosting state, the main controller controls a defrosting heater to perform defrosting, if the detected temperature of the evaporator is in a normal range, the main controller calculates whether the starting time of the refrigerator from the last defrosting is more than 4 hours or not, and if so, the main controller calculates the temperature of the evaporator at the shutdown time of the compressor at this time and subtracts the temperature parameter DTF of.
If DTF is less than 1.0 ℃, the main controller judges that the state is that the user opens the door to fetch the objects or puts a small amount of food into the freezing chamber daily without entering a quick-freezing mode, and returns to the main program.
If the DTF is higher than 4.0 ℃, the main controller judges that the refrigerator door seal is poor, the refrigerator is in an abnormal use state, the main controller does not enter a quick-freezing mode and sends a use abnormity prompt to a user, and the main controller returns to the main program so as to reduce energy loss caused by poor seal of the refrigerator door seal.
If the temperature is more than or equal to 4.0 ℃ and more than or equal to 1 ℃, the main controller judges that a large amount of food is put into the freezing chamber for the user at the moment, and the main controller executes a quick-freezing mode to control the compressor to run at a high rotating speed and reduce the temperature control gear below the conventional refrigerating temperature.
The refrigerator enters a quick-freezing mode, the compressor continuously runs for 24 hours and then exits the quick-freezing mode, the main controller forcibly controls the refrigerator to defrost, and after defrosting is completed, the main controller controls the temperature control gear to recover to the conventional refrigeration temperature and returns to the main program.
During the quick-freezing mode, the defrosting heater is not operated, and the main controller also calculates the door opening time T1 and the door opening times D1 of the freezing chamber of the refrigerator.
If the door opening time T1 of the freezing chamber is larger than or equal to the preset door opening time T, or the door opening times D1 are larger than or equal to the preset door opening times D, the main controller judges that the user takes out the food to be frozen midway, the main controller exits the quick-freezing mode in advance, the main controller controls the defrosting heater to forcibly defrost, defrosting is completed, the main controller controls the temperature control gear to recover to the conventional refrigeration temperature, and the main controller returns to the main program.
If the door opening time T1 of the freezing chamber is less than the preset door opening time T, or the door opening times D1 are less than the preset door opening times D, the main controller judges that the door opening is the action of daily fetching or putting in a small amount of food by a user, the main controller continues to execute the quick-freezing mode, the quick-freezing mode is withdrawn after the compressor continuously runs for 24 hours, the main controller forcibly controls the refrigerator to defrost, and after the defrosting is finished, the main controller controls the temperature control gear to recover to the conventional refrigerating temperature and return to the main program.
The parameters of the preset door opening time T and the preset door opening times D can be set according to the refrigerator model, and it can be understood that if the door opening times D1 of a user exceed the preset door opening times D and/or the door opening time T1 exceed the preset door opening time T, the main controller can exit the quick-freezing mode in advance according to parameter feedback, so as to ensure that a large amount of frost does not form inside the refrigerator.
The formula value of the key control evaporator temperature change parameter DTF of the scheme is more than or equal to 1 ℃ is calculated by the following calculation formula:
reckoning 1, calculation of refrigeration power required for cooling food, taking beef as an example, the specific heat capacity before freezing C =3.17kJ/kg. ℃, namely, the cold quantity required by 1kg of unfrozen beef for reducing 1 ℃ is 3.17kJ, and the theoretical calculation is as follows: taking the environment temperature of 25 ℃ as an example, taking fresh beef as an example, taking the environment temperature of 25 ℃ before putting the beef into a refrigerator, taking the weight M of the beef to be frozen to be more than or equal to 2kg, taking the time T required for freezing the beef to-18 ℃ as 24h, and putting the beef into the refrigerator at 25 ℃ as the working condition: and (5) stabilizing the running state. The heat released by the temperature reduction of the object satisfies the following formula: q = C × M × Δ T, where C is the specific heat capacity of the solid, M is the fixed mass, and Δ T is the fixed temperature change in K (kelvin). Neglecting latent heat release in the beef freezing process, the heat released when 2kg of beef at the temperature of 25 ℃ is cooled to-18 ℃ is 136kJ, and the cooling time is 24h, the power of the heat released in the beef cooling process is 3.14W, namely the refrigerator needs additional 3.14W of refrigeration power for cooling the newly added 2kg of beef to-18 ℃ within 24 h.

According to the theoretical calculation, the DTF is not less than 1.0 ℃ as the judgment condition for entering the quick-freezing mode, and meanwhile, the parameter can be adjusted to be optimal by combining with experimental check according to different product designs.
