The air flows into the evaporation chamber defined by the intermediate separation plate 7 and the rear cover plate 8 through the second orifice 72 in the intermediate separation plate 7 and the air is cooled in the evaporation chamber after heat exchange with the evaporator 91. The cooled air flows to the first air outlet channel 53 or to the second air outlet channel 55 under suction by the fan 92 through the first orifice 71 in the intermediate separation plate 7 and then the chilled air enters the corresponding cold chambers under the action of the wind pressure generated by the fan 92 through the first air outlet port 61 or the second air outlet port 63, in order to complete the circulation of air in the cooler 100.

[0082] As shown in Fig. 4 to Fig. 6, the refrigerator 100 according to embodiments of the present invention also includes two temperature controllers 93 and a series of air ports 51 and the various air ports 51 are located in the assembly air channels 2 and configured to open or close the air outlet door. The temperature controller 93 is configured to detect the temperatures of the cold chambers and to control the air ports 51 so that they are opened or closed according to a defined reference value. Two temperature controllers 93 are positioned, respectively, between the first air outlet port 61 and the first air return port 62 or between the second air outlet port 63 and the second air return port 64. As the air flows between the air outlet ports or the air return ports, temperature controllers 93 are mounted between the air outlet ports and the air return ports to increase the accuracy of the temperature detection results and the Cold chamber temperatures can be effectively detected.

[0083] A process for controlling the temperature of the cold compartment of the refrigerator 100 is briefly described with reference to Fig. 4 to Fig. 7.

[0084] When partition plate 3 divides freezer compartment 12 in the upper cold chamber 121 and in the lower cold chamber 122, the upper cold chamber 121 is used as an example. When the temperature controller 93 detects that the temperature of the upper cold chamber 121 is less than a previously set temperature, the temperature controller

93 controls air port 51 on the first air outlet port 61 to be closed, so that air cannot flow through the first air outlet channel 53 and cooling to the upper cold chamber 121 is suspended. When the temperature controller 93 detects that the temperature in the upper cold chamber 121 is higher than the previously set temperature, the temperature controller 93 controls the air port 51 on the first air outlet port 61 to be opened and the air cooled. can flow through the first air outlet port 61 to cool the upper cold chamber

121. The temperature controller 93 for the lower cold chamber 122 operates in the same way as the temperature controller 93 for the upper cold chamber 121, which will not be described in detail.

[0085] When the partition plate 3 is disassembled, the upper cold chamber 121 and the lower cold chamber 122 are combined in an integral freezer compartment 12 and the two temperature controllers 93 can together detect the temperature of freezer compartment 12 or a single temperature controller 93 detects the temperature of the freezer compartment 12. When the temperature controller (s) 93 detects that the temperature of the freezer compartment 12 is lower than the current temperature, the controller (s) temperature 93 controls (m) the air ports 51 on the first air outlet port 61 and on the second air outlet port 63 to be closed, so that air cannot flow through the first air outlet channel 53 and from the second air outlet channel 55 and the cooling to the freezer compartment 12 on the upper side is suspended. When temperature controller (s) 93 detect (s) that the temperature of freezer compartment 12 is higher than the current temperature, temperature controller (s) 93 control (s) the air ports 51 in the first air outlet port 61 and the second air outlet port 63 to be opened, so that chilled air can flow through the first air outlet port 61 and the second air outlet port 63 to cool the refrigerator compartment 12.

[0086] The refrigerator 100 according to the embodiments of the present invention is equipped with a door plate to separate the freezer compartment 12 in an upper cold chamber 121 and the lower cold chamber 122 and the air channels can operate individually, so that two cold chambers can perform refrigeration individually. With temperature controllers 93 and air ports 51, the refrigerator 100 can control a communication status of the air channels for the two cold chambers according to the needs of the user, so that the temperatures in the two cold chambers can be controlled. The refrigerator 100 can provide diversified operating modes to provide different operating needs for the refrigerator 100 desired by different users.
