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.

Proposed is a refrigerator, wherein a cool air flow path for an ice making compartment and a cool air flow path for a freezing compartment are integrally formed on opposed surfaces between a shroud and a grill fan, and a freezing fan and an ice making fan are collectively installed at the shroud. Therefore, the cool air flow path for the ice making compartment and the cool air flow path for the freezing compartment are defined between the grill fan and the shroud by the operation of intimately coupling the shroud to the grill fan.

In an example, a transformable cargo container for use with ground and air transportation vehicles is disclosed. The cargo container includes a main container body defining a storage chamber therein and including at least one inlet. The cargo container also includes a transformable assembly coupled to the main container body and positioned at an exterior of the main container body. The transformable assembly includes one or more supplemental containers and one or more supply ducts, at least one of the supplemental container(s) being configured to house refrigeration equipment. The transformable assembly is movable between an aircraft configuration and a ground configuration. Based on the transformable assembly being in either the aircraft configuration or the ground configuration, the refrigeration equipment is configured to supply coolant into the main container body via the supply duct(s) and the inlet(s).

A refrigerated display case includes a housing surrounding multiple shelves. An air distribution gap is defined behind the shelves. An air return passage is defined below the shelves. A radial cross-flow fan is disposed in a fan region of the air return passage. The radial cross-flow fan includes an output connected to the air distribution gap. A primary cooling microchannel heat exchanger is disposed in the fan region downstream of the radial cross-flow fan such that air output from the radial cross-flow fan to the air distribution gap passes through the primary cooling microchannel heat exchanger. A pre-cooler microchannel heat exchanger is disposed upstream of the primary cooling microchannel heat exchanger.
