Abstract: Disclosed is a refrigerator that facilitates access to each evaporator and improves maintenance performance. In the refrigerator, a different temperature of cold air cooled by each evaporator is brought into each cooling chamber with a different temperature range and different humidity range. The refrigerator includes a main refrigerator body including a machine room and a cooling chamber, an evaporator contained in the machine room, and a cooling unit detachably mounted in the machine room and including a compressor, a condenser, and an insulation member, wherein the cooling unit, while mounted in the machine room, has the insulation member tightly contact an inner wall of the machine room to form an insulation space, and the evaporator is contained in the insulation space.

Abstract: A communication management server includes a processor and a memory device configured to store a program. The program causes the processor to acquire first identification information configured to indicate a network service and second identification information configured to manage a communication device receiving the network service. The program also causes the processor to generate first setting information configured to connect a network providing server corresponding to the network service and the communication device based on the first identification information and the second identification information. The program also causes the processor to transmit the first setting information generated in the generation unit to the communication device.

Abstract: A refrigerator includes a storage chamber, an evaporator configured to cool the storage chamber, and an air passage through which cold air generated by the evaporator flows. The air passage includes a blower fan configured to blow the cold air to the storage chamber, and a trap part in which warm air generated by a defrosting operation stays, such that warm air generated by the defrosting operation is prevented from being introduced into the inner space of the refrigerator through the air passage. The refrigerator reduces the defrosting operation time, efficiently prevents increase of the inner temperature of the refrigerator due to warm air during the defrosting operation, reduces a temperature difference in inner temperature of the refrigerator, and prevents food stored in the refrigerator from being rotten due to a temperature change.
