Abstract: A condenser fan includes a lock hub and multiple blades that are fastened to the hub. Each of the blades includes six planes, each of which having variable parameters including pitch angle, sickle, chord length, and blade curve. For each embodiment of the evaporator fan, the blades are identically configured.

Abstract: A centrifugal blower includes a blower base, multiple blades fastened to the blower base, a hub integrated to a central portion of the blower base, and a top shroud to provide surrounding coverage to the multiple blades. The centrifugal blower is housed within an evaporator. The centrifugal blower may operate at operating speeds that are lower than those of typical or currently known implementations while generating an airflow that meets or even exceeds those of the typical or currently known implementations.

Abstract: A fluid distributing device that can be utilized in a refrigerated transport unit, an air duct for an HVAC system in a building, a heat exchanger, etc. The fluid distributing device includes a body having an outlet that directs fluid from the fluid distributing device and a positive fluid displacement device configured to draw fluid into an interior of the body. A method for a fluid distributing device to distribute air within an interior space of the refrigerated transport unit includes drawing air into the fluid distributing device and discharging air out of the fluid distributing device via an outlet.
