Left and right edge portions of an external casing of a container refrigeration apparatus each include a column member that is continuous from the upper end to the lower end of a casing. Left and right edge portions of an internal casing each include a side plate that is continuous from the upper end to the lower end of the casing. The column members of the external casing and the associated side plates of the internal casing are fixed together, thereby increasing the strength of the casing including the external casing and the internal casing.

Container refrigeration apparatus

A space which is present between an air intake surface () provided with an air intake port and an air filter () is regarded as a primary space (P) through which air flows into the air filter (), and a plurality of spaces, each of which is present between one of other surfaces of the air filter () and a filter box (), are regarded as secondary spaces (Q) into each of which the air flows out from the air filter (), so that the air is taken out from side surfaces and an upper surface of a filter unit (). This configuration reduces the increase in size of the filter unit () of a gas supply device () even if a dust holding capacity of the filter is made larger than before.

Filter unit, gas supply device, inside air conditioner, and cooling device for container

In a gas supply device that supplies gas to a target space through a filter unit, the filter unit is composed of a filter box and an air filter housed in the filter box, and the air filter is a filter having a filter substrate made of a membrane filter and a fibrous coating layer covering a surface of the filter substrate through which air is sucked.

Gas supply device, device for controlling inside air, and refrigeration device for container

A fan includes a core part, a vanes, a ring part and a flow rectifying member. The ring part includes first second and third parts. The first part includes a first end overlapping with a flow rectifying member end and extends axially on a radially inner side of the flow rectifying member. The second part includes a second end spaced from the flow rectifying member end, overlapping with the flow rectifying member, and connected to the first end. The third part is connected to the second end, and extends on the radially outer side of the flow rectifying member end. The second end overlaps with a virtual point reached by the flow rectifying member end being linearly extended toward an upstream side. A first dimension, a radial length of the third part, is at least 0.5 times a first straight-line distance between the flow rectifying member end and the virtual point.

Fan and refrigeration apparatus including fan

A propeller fan includes a rotary blade hub driven in rotation about a rotation axis, and a rotary blade installed at an outer periphery of the rotary blade hub. The rotary blade includes a rotary blade body protruding from an outer peripheral surface of the rotary blade hub, and a rib formed on an outer peripheral edge portion of a pressure surface of the rotary blade body so as to extend along an outer peripheral edge of the rotary blade body.

Propeller fan and blower unit

In an attachment portion where a side edge portion of an opening of a trailer and a casing are connected together, a vertically-extending groove is formed in one of the trailer or the casing and a vertically-extending raised portion is formed in the other one of the trailer or the casing so as to be fitted into the groove.
