A modular refrigerator including a main cabinet, and a sub-cabinet selectively coupleable to a right side, an upper side, and a left side, of the main cabinet. The main cabinet includes a cooling unit, a first connection duct for cold air generated by the cooling unit to flow toward the right side, a second connection duct for the cold air to flow toward the upper side, and a third connection duct for the cold air to flow toward the left side. The sub-cabinet includes a first branch duct that, when the sub-cabinet is coupled to the right side, communicates with the first connection duct, a second branch duct that, when the sub-cabinet is coupled to the upper side, communicates with the second connection duct, and a third branch duct that, when the sub-cabinet is coupled to the left side, communicates with third connection duct.

The present embodiments relate to a handle assembly for a refrigeration apparatus. The handle assembly can be detachably assembled on either side of a cabinet door of the refrigeration apparatus, the handle assembly comprising: a handle, a handle bracket, and an elastic member, wherein the handle comprises a handle portion and an extension on a side of the handle portion, characterized in that the handle is movably assembled in the handle bracket, wherein the handle portion of the handle is assembled in a first portion of the handle bracket, and the extension of the handle is assembled in a second portion of the handle bracket, and a protrusion is disposed at one end of the extension; and the elastic member is assembled in the second portion of the handle bracket, and the extension of the handle is connected with the elastic member. The present embodiments can realize the opening of the cabinet door of the refrigeration apparatus in two directions, thereby overcoming the disadvantage that it is difficult to open the cabinet door of the refrigeration apparatus due to restriction by the opening direction of the cabinet door in a small space, especially in an in-vehicle environment.

A method for controlling the temperature and humidity level of the air contained in an enclosed refrigerated space includes the step of measuring the temperature of air in the space. The space includes a cooler having a plurality of cold batteries; at least one coolant temperature sensor at the input and at least one coolant temperature sensor at the output of the cooler; at least one fan with an adjustable, reversible direction of ventilation for producing a variable flow of air through the cooler; at least one temperature sensor upstream of the fan; at least one temperature sensor downstream of the cooler; at least one humidity level sensor upstream of the fan; and at least one humidity level sensor downstream of the cooler. The control is affected by reference values given initially for the temperature and humidity level in the enclosed space.

Systems and methods are provided for bimodal refrigeration, which uses a combination of mechanical refrigeration and phase change material (PCM) cells to provide cooling for one or more units of storage, such as freezers, coolers, storage or display cases, open cases (without doors), closed cases (with doors), rack systems (with compressors located remotely), self-contained refrigeration systems (with embedded compressors), in an optimal and efficient manner. In some embodiments, the systems and methods employ intelligent controls which may monitor and receive input for system conditions, time of day, and other conditions, and turn on/off the mechanical refrigeration as appropriate to provide for efficient and cost-effective use of energy.

A refrigerator includes a first refrigerator including a first cabinet and a second refrigerator including a second cabinet, and operating independently from the first refrigerator. A first connector is installed on the first cabinet; and a second connector is installed on the second cabinet to correspond to the first connector. The second connector is configured to be coupled to the first connector, such that in a state in which the first connector and the second connector are coupled to each other, a movement of the first cabinet in a first direction with respect to the second cabinet is allowed, and a movement of the first cabinet in a second direction with respect to the second cabinet is restricted, with the second direction being perpendicular to the first direction.

A pair installation type of refrigerator system provides a plurality of refrigerators installed in parallel. A first refrigerator includes a first discharge portion formed on a side wall of the first cabinet to communicate with a first machine room, and a flow guide detachably coupled to the side wall of the first cabinet to cover the first discharge portion. A second refrigerator includes a second door that is opened such that an opening direction is symmetrical to that of the first door in a state in which the second refrigerator is disposed adjacent to the first refrigerator, and a decor member disposed in a space between the first refrigerator and the second refrigerator to shield a front side in a state in which the second refrigerator is disposed adjacent to the first refrigerator. The decor member fixes the first cabinet and a second cabinet.

An embodiment of the present disclosure relates to a space placement type refrigerator system and includes a case configured to be positioned in a space away from a wall surface and having an opened front surface and an opened rear surface; a plurality of refrigerators provided in the case and configured to be exposed to the opened front surface or the opened rear surface of the case; and a receiving member provided in the case and configured to be exposed to the same surface as the plurality of refrigerators, in which at least one of the plurality of refrigerators is disposed to be accessible from a direction opposite to that of the other refrigerator.

A modular refrigeration assembly includes a plurality of refrigerators and each of the refrigerators may contain perishable items. A selected number of the refrigerators are removably coupled together. Thus, the selected refrigerators may facilitate a selected amount of cold storage area. The selected refrigerators are selectively uncoupled from each other. Thus, the selected refrigerators may be moved through an area that has a height and a width that is less than a height and a width of the selected refrigerators when the selected refrigerators are removably coupled together.

A refrigerator includes a body, first and second storage compartments and a machine compartment formed in the body, a blower fan disposed in the machine compartment, first and second refrigerating units comprising first and second compressors to compress first and second refrigerants, respectively, first and second condensers to condense the first and second refrigerants, respectively, first and second expansion valves to expand the first and second refrigerants, respectively, and first and second evaporators to evaporate the first and second refrigerants, respectively, the first and second refrigerating units supplying cold air to the first and storage compartments, respectively. The first compressor, the second compressor, and the first condenser are disposed in the machine compartment and are cooled by forcible flow of air caused by the blower fan, and the second condenser is disposed outside the machine compartment and is cooled by natural convection of air.

Systems, apparatuses, and methods are provided herein for providing temperature control. An apparatus for temperature control comprises a portable housing configured for delivery of items, an insulated storage compartment in the portable housing and configured to hold a plurality of items during a transport of the portable housing, a temperature control device configured to affect the temperature inside the insulated storage compartment, and a host coupler configured to couple with a host temperature control system to allow the host temperature control system to affect the temperature inside the insulated storage compartment. Wherein the temperature control device is configured to affect the temperature inside the insulated storage compartment without the host coupler being coupled to the host temperature control system.
