Alternatively, since the temperature of the coolant is higher than the cooling temperature of the freezing evaporator 232, in order to reduce the influence of the temperature of the coolant on the temperature of the freezing evaporator 232 during the transition from the cooling of the refrigerating evaporator 242 to the cooling of the freezing evaporator 232, the control logic for the cooling of the freezing evaporator 232 may be set as follows: when the freezing evaporator 232 meets the first refrigeration condition, the control device controls the freezing fan 25 to be started in a delayed mode for X minutes, the value of X needs to balance the influence of the natural freezing temperature and the temperature of the coolant, the range of X is 1-10 minutes, and preferably, X is 5 minutes, so that after the freezing evaporator 232 refrigerates for 5 minutes, the freezing evaporator 232 has made more cold, and the freezing fan 25 is started at the moment, so that the temperature in the freezing chamber 11 can be quickly reduced.
According to some embodiments of the invention, the refrigeration device further has a defrosting phase, the control method further comprising: in the defrosting stage; controlling a first temperature detection device to detect the temperature in the freezing chamber and controlling a second temperature detection device to detect the temperature of the refrigerating evaporator, and controlling the starting and stopping of a defrosting program of the freezing evaporator according to the detection result of the first temperature detection device; and controlling the starting and stopping of a defrosting program of the refrigeration evaporator according to the detection result of the second temperature detection device.
According to some embodiments of the present invention, referring to fig. 5, the controlling of the start and stop of the defrosting process of the freezing evaporator according to the detection result of the first temperature detection device includes: acquiring that the temperature T1 in the freezing chamber detected by the first temperature detection device is not higher than a first set exit temperature T11; and determining that the temperature T1 in the refrigerating chamber is lower than a third set temperature T30, and controlling to execute a defrosting program of the refrigerating evaporator, wherein the third set temperature T30 is lower than the first set exit temperature T11.
Specifically, when the temperature T1 in the freezing compartment 11 detected by the first temperature detecting device 27 is not higher than the first set exit temperature T11, the control device controls the freezing evaporator 232 to stop cooling, and when the temperature T1 in the freezing compartment 11 is lower than the third set temperature T30, it indicates that the freezing evaporator 232 is in the defrosting condition, and the control device may control the freezing evaporator 232 to start the defrosting process.
According to some embodiments of the present invention, referring to fig. 5, the controlling of the start and stop of the defrosting process of the refrigeration evaporator according to the detection result of the second temperature detection device includes: acquiring that the temperature T2 of the refrigeration evaporator detected by the second temperature detection device is not higher than a second set exit temperature T21; and determining that the temperature of the refrigerating evaporator is lower than 0 ℃, controlling to execute a defrosting program of the refrigerating evaporator, and setting the second set exit temperature T21 to be higher than 0 ℃.
Specifically, when the temperature of the refrigerating evaporator 242 detected by the second temperature detecting device 28 is not higher than the second set exit temperature T21, the control device controls the refrigerating evaporator 242 to stop cooling, since the working temperature of the refrigerating chamber 13 is usually maintained at 2 ℃ to 8 ℃, when the temperature of the refrigerating evaporator 242 is lower than 0 ℃, it indicates that frost is accumulated on the surface of the refrigerating evaporator 242, and defrosting is required, and at this time, the control device may control the refrigerating evaporator 242 to start executing a defrosting program.
Here, if the crystallization temperature T of the cold storage agent used is lower than 0 ℃, then when the cold storage agent in the cold storage box 243 is crystallized, it is described that the temperature T2 on the surface of the refrigeration evaporator 242 is already lower than 0 ℃, frost is already accumulated on the surface of the refrigeration evaporator 242, and defrosting is required; if the crystallization temperature T of the used coolant is higher than 0 ℃, frost is accumulated on the surface of the refrigerator and defrosting is required only when the temperature T2 of the refrigerator evaporator 242 detected by the second temperature detecting device 28 is lower than 0 ℃.
In addition, it should be noted that the defrosting process performed by the refrigeration evaporator 242 is performed according to a certain period, so that energy waste and food material deterioration caused by frequent defrosting can be avoided as much as possible. Specifically, several factors affecting the refrigeration defrosting cycle include an ambient temperature, a door opening frequency and a door opening time, for example, as shown in table 2, when the ambient temperature of the refrigeration equipment 100 is 32 ℃, the door opening frequency of the refrigerating chamber 13 is 0 to 5 times, and the time for opening the door each time is 0 to 1 minute, the cycle of the refrigeration evaporator 242 executing the defrosting program is 48 hours, that is, the interval period from the end of the current defrosting to the start of the next defrosting of the refrigeration evaporator 242 is 48 hours; when the ambient temperature of the refrigeration apparatus 100 is 32 ℃, the number of door opening times of the refrigerating chamber 13 is greater than 10, and the time for opening the door each time is greater than 5 minutes, the cycle of the defrosting process performed by the refrigerating evaporator 242 is 12 hours, that is, the interval period from the end of defrosting to the start of defrosting next time by the refrigerating evaporator 242 is 12 hours.
Further, in order to minimize the effect of the refrigerating defrosting on the temperature of the freezing compartment 12, the defrosting of the refrigerating evaporator 242 and the defrosting of the freezing evaporator 232 are performed in the same manner as possible. For example, when it is determined that the refrigerating evaporator 242 needs defrosting, it is first determined whether the freezing evaporator 232 needs defrosting, if the time from the beginning of defrosting of the freezing evaporator 232 is less than a time, the refrigerating evaporator 242 waits for the freezing evaporator 232 and synchronously executes a defrosting program, and if the time from the beginning of defrosting of the freezing evaporator 232 is greater than a time, the refrigerating evaporator 242 is controlled to immediately start executing the defrosting program, where a ranges from 30 minutes to 90 minutes, and preferably, a is 60 minutes.
