In prior art single system side by side refrigerators where the evaporator is located in the back of the freezer compartment as shown in fig. 1, this design has several disadvantages:
firstly, the evaporator is placed on the freezing back, so that the cold energy can be dissipated to the external environment through the refrigerating back, and meanwhile, the freezing air duct and the evaporator can occupy a large amount of freezing volume to reduce the volume ratio.
Secondly, because the air supply of the freezing chamber and the air supply of the refrigerating chamber are not provided with air doors, when the refrigerator is refrigerated, the air in the refrigerating chamber easily enters the freezing chamber through the air openings, and the running energy consumption of the whole refrigerator can be improved because the air temperature in the refrigerating chamber is often higher and then enters the freezing chamber.
Thirdly, because freezing room air supply and cold-stored room air supply do not set up the air door, when the defrosting heater began to work and defrosts, the produced hot-air of defrosting in-process can enter into the indoor portion through the wind gap, according to the law of conservation of energy, this kind of structure can increase the time of defrosting and influence the indoor temperature of refrigeration simultaneously and cause the rate of operation of refrigerator complete machine to improve thereby lead to the energy consumption increase.
