A refrigerating system may include a compressor configured to compress a non-azeotropic mixed refrigerant, a condenser configured to condense the compressed non-azeotropic mixed refrigerant, a three-way valve configured to branch the non-azeotropic mixed refrigerant condensed by the condenser, a first evaporator configured to supply cold air to a first interior space, a second evaporator configured to supply cold air to a second interior space at a temperature higher than at a temperature of the first interior space, and a capillary tube configured to expand the non-azeotropic mixed refrigerant branched by the three-way valve and supply the expanded non-azeotropic mixed refrigerant to at least one of the first evaporator or the second evaporator. With such features, a high-efficiency refrigerating system to which the non-azeotropic mixed refrigerant is applied may be implemented.

Refrigerating system using non-azeotropic mixed refrigerant

A method for controlling a refrigerating system using a non-azeotropic mixed refrigerant is provided. The refrigerating system may include a first evaporator configured to supply cold air to a freezer compartment located upstream and a second evaporator configured to supply cold air to a refrigerating compartment located downstream, based on a flow direction of the non-azeotropic mixed refrigerant. The method may include a first operation comprising operating a compressor, a freezer compartment fan to blow air to the first evaporator, and a refrigerating compartment fan to blow air to the second evaporator; a second operation comprising when the freezer compartment reaches a target temperature or the refrigerating compartment reaches a target temperature, continuously operating the compressor, and stopping the freezer compartment fan or the refrigerating compartment fan corresponding to one of the freezer compartment or the refrigerating compartment that reaches the target temperature; and a third operation comprising when both the freezer compartment and the refrigerating compartment reach the target temperatures, turning off both of the refrigerating compartment fan and the freezer compartment fan and stopping the compressor.

Method for controlling refrigerating system using non-azeotropic mixed refrigerant

A refrigerating apparatus may include a main body having an interior space in which an article is accommodated, a door configured to open and close an opening of the main body, a compressor configured to compress a non-azeotropic mixed refrigerant, a condenser configured to condense the compressed non-azeotropic mixed refrigerant, a hotline provided at a contact portion between the main body and the door through which the condensed non-azeotropic mixed refrigerant flows, an expander configured to expand the non-azeotropic mixed refrigerant, heat of which is radiated by the hotline, and an evaporator configured to evaporate the expanded non-azeotropic mixed refrigerant to supply cold air to the interior space. According to such structure, even when the non-azeotropic mixed refrigerant is used, a function of the hotline to prevent dew formation may be normally performed with hot refrigerant.

Refrigerating apparatus using non-azeotropic mixed refrigerant

An embodiment of the present invention relates to a deep freezer. A deep freezer according to an embodiment of the present invention comprises a plurality of heat exchangers installed to an inlet pipe and performing a heat exchange of a mixed refrigerant suctioned into a compressor. The mixed refrigerant comprises: a high temperature refrigerant which is one selected from among butane (N-butane), 1-butene, and isobutane; and a low temperature refrigerant consisting of ethylene.

Deep freezer

A refrigerator includes a main body in which a first storage compartment is defined, and a heat exchange chamber defined in the main body. An evaporator received in the heat exchange chamber. A second storage compartment is provided in the first storage compartment and a quick cooling module to cool an inside of the second storage compartment is provided, where the quick cooling module heat-exchanges with a refrigerant pipe of the evaporator. The quick cooling module includes a thermal conductive unit in thermal conduction with the refrigerant pipe, and a thermoelectric device having a first surface in thermal conduction with the thermal conductive unit to heat-exchange with the thermal conductive unit when current is supplied and a second surface facing the second storage compartment.

Refrigerator

A refrigerator is provided. In the refrigerator, cool air within the heat exchange chamber is supplied into a drawer assembly disposed inside a storage space, and also the inside of the drawer assembly is cooled using a thermoelectric module to quickly cooling the inside of the drawer assembly. Thus, food storage performance may be improved.

A refrigerator includes a case, a drawer, and a ventilation port opening/closing member. The case has a storage space formed therein and the drawer stores food and opens and closes the storage space while being supported by the case so as to be movable with respect to the case. The ventilation port opening/closing member ventilates the storage space. Here, the drawer includes a ventilation port for ventilating the storage space, and the ventilation port opening/closing member moves in the direction as the drawer to open and close the ventilation port.
