The present disclosure relates to a refrigerator. The refrigerator according to an embodiment of the present disclosure comprises: an evaporator; a defrost heater; a temperature sensor to sense ambient temperature around the evaporator; and a controller to control the defrost heater, wherein the controller is configured to: perform a defrost operation mode in a case of reaching a defrosting operation start time point; perform, based on the defrost operation mode, a continuous operation mode in which the defrost heater is continuously turned on, and a pulse operation mode in which the defrost heater is repeatedly turned on and off; and perform the continuous operation mode again after performing the pulse operation mode. Accordingly, defrosting efficiency may be improved, and power consumption may be reduced.

A refrigeration unit having an evaporator tube, a heater tube in a spaced relationship with the evaporator tube, a wire that couples the evaporator tube to the heater tube, and a bracket having a first panel configured to contact the heater tube and a second panel that defines a recess configured to receive the heater tube therein.

A method for retrofitting an aircraft air conditioning unit drainage system comprises the step of removing drain pipe from the unit housing. A hole from which the drain pipe extends is plugged. A first location within a unit housing is determined where during operation of the unit air pressure is lower than at a second location. A second location below the first location is also determined where pooling occurs. A first and a second conduit with first and second internal diameters are respectively located at the first and the second locations. The first conduit and the second conduit are connected to a third conduit which extends generally vertically and which has a third internal diameter that is generally equal to the first internal diameter. A fourth conduit with a fourth internal diameter that is less than the second internal diameter is connected to the third conduit below the second location.

A refrigerator is proposed. Due to a first heater provided in a damper assembly, a damper assembly or the connection portion of the damper assembly with a supply duct is prevented from freezing, and due to a second heater provided in the supply duct, the connection portion of the supply duct with the damper assembly or the inside of the supply duct is prevented from freezing.

A refrigerator includes a housing body including an inner space of the refrigerator and a cooling cycle mechanism configured to cool the inner space. The housing body includes a plurality of housing body elements separated along a predetermined separate surface, and the plurality of housing body elements is removably coupled to each other to allow an end surface of one of the plurality of housing body elements to face an end surface of another one of the plurality of housing body elements. A sealing mechanism configured to form an air surface between opposite end surfaces is provided to prevent air from flowing into or from the inner space through between the opposite end surfaces.
