It should be noted that the first air duct 302 is separated from the first storage compartment 301 by a first air duct cover plate 111 with a heat preservation function, the first air duct cover plate 111, the first evaporator 102 and the first fan 103 form an air duct system of the first compartment 300, and an air outlet and an air inlet of the air duct system are both inside the first compartment 300; the second air duct 402 is separated from the second storage compartment 401 by a second air duct cover plate 112 with a heat preservation function, the second air duct cover plate 112, the second evaporator 104 and the second fan 105 form an air duct system of the second compartment 400, an air outlet and an air inlet of the air duct system are all arranged in the second compartment 400, no air duct is arranged between the first compartment 300 and the second compartment 400, and the first evaporator 102 and the second evaporator 104 are connected in series, so that the refrigeration equipment provided by the embodiment of the application is a single-system double-circulation refrigeration system.
In the refrigeration apparatus provided by the embodiment of the present application, the first compartment 300 may be a cold storage functional compartment, and the second compartment 400 may be a cold storage functional compartment, and the first compartment 300 and the second compartment 400 are not communicated with each other, so that the problem of tainting odor between the two compartments can be solved. Since the first evaporator 102 and the second evaporator 104 are independent of each other and can be easily matched with the compressor 101, the refrigeration apparatus can set the temperature of the refrigerating function chamber to-10 ℃ or higher and the temperature of the freezing function chamber to 1 ℃ or lower.

DELTA.t, t3 is t 1-DELTA.t, and Δ t > 0 ℃. It should be noted that, since the temperature adjustment range of the first compartment 300 can reach below 0 ℃, when the set temperature is greater than 0, and when the first evaporator 102 works, the measured temperature of the first storage compartment 301 may be less than 0 ℃, and the shutdown set temperature of the first compartment 300 may be greater than 0 ℃ or less than 0 ℃.

if the first heater 109 is powered on, controlling the first fan 103 to stop running; if the first heater 109 is de-energized, the first blower 103 is controlled to operate or stop operating according to the operating state of the compressor 101, the measured temperature of the first storage room 301, and the temperature of the first evaporator 102.
The state of the first fan 103 is flexibly controlled through the running state of the compressor 102, the actually measured temperature of the first storage room 301 and the temperature of the first evaporator 102, so that the refrigeration equipment can meet the requirement, and the power consumption is reduced.
It should be noted that if the compressor 101 is operated and the temperature of the second evaporator 104 is less than the shutdown set point of the second compartment 400, the second fan 105 is controlled to operate; and controlling the second fan 105 to stop running if the compressor 101 stops running and the temperature of the second evaporator 104 is greater than the starting-up set value of the second compartment 400, wherein the stopping-up set value of the second compartment 400 is greater than the starting-up preset value.

when the first heater 109 is powered off, if the compressor 101 is operated and the measured temperature of the first storage room 301 is greater than or equal to a first preset value, controlling the first fan 103 to operate; and if the compressor 101 is operated and the measured temperature of the first storage room 301 is less than or equal to a second preset value, controlling the first fan 103 to stop operating, wherein the second preset value is less than the first preset value.
For example, the first preset value may be t2, and the second preset value may be t 3.
When the first heater 109 is powered off and the temperature of the first storage room 301 is higher than the power-on set value, the first fan 103 is controlled to operate, so that the cold energy generated by the first evaporator 102 can be blown to the first storage room 301 to reduce the temperature of the first storage room 301, and the first fan 103 is controlled to stop operating until the temperature of the first storage room 301 is lower than the power-off set value, so that the stability of the temperature of the first storage room 301 can be ensured.

when the first heater 109 is powered off, if the compressor 101 stops operating, the measured temperature of the first storage room 301 is greater than or equal to a first preset value, and the temperature of the first evaporator 102 is less than or equal to a third preset value, controlling the first fan 103 to operate, wherein the third preset value is less than the first preset value; if the compressor 101 stops operating, the measured temperature of the first storage room 301 is greater than or equal to a first preset value, and the temperature of the first evaporator 102 is greater than the first preset value, controlling the first fan 103 to stop operating; and if the compressor 101 stops operating and the measured temperature of the first compartment 301 is less than or equal to a second preset value, controlling the first fan 103 to stop operating, wherein the second preset value is greater than a third preset value and the second preset value is less than the first preset value.
Illustratively, the third preset value may be t2- Δ t.
It should be noted that, when the first heater 109 is powered off, the temperature of the first evaporator 102 is lower than the measured temperature of the first storage room 301 and the temperature difference is large, the first fan 103 is controlled to operate, and the cold generated during the operation of the first evaporator 102 can be blown into the first storage room 301 to reduce the temperature of the first storage room 301 until the temperature of the first storage room 301 is reduced to the set temperature, so as to reduce the energy consumption. When the temperature of the first evaporator 102 is in the interval (T2- Δ T, T2), in order to prevent the time interval between the operation and the stop of the first fan 103 from being excessively short, the state of the first fan 103 may be controlled to coincide with the state before the temperature of the first evaporator 102 reaches T2- Δ T.
According to the refrigeration equipment and the control method, the operation or the stop operation of the fan is controlled according to the operation state of the compressor of the refrigeration equipment, the actual measurement temperature of the refrigeration chamber and the temperature of the evaporator, the working state of the fan is flexibly controlled, the refrigeration requirement is met, meanwhile, the energy consumption of the refrigeration equipment is reduced, the stability of the temperature of the refrigeration chamber is kept, and the product competitiveness is improved.
