Abstract

A transport refrigeration system including a compressor, a prime mover for the compressor, a condenser, and an evaporator blower assembly. The evaporator blower assembly includes a shaft driven by the prime mover, a first blower fixed to the driven shaft, a second blower journaled for rotation about the driven shaft, and a clutch for coupling and decoupling the first and second blowers. The volume of air moved through the evaporator and into the conditioned space or cargo area is thus selectable based upon need of the transport refrigeration system, without the necessity of changing the speed of the prime mover. The resulting savings in power realized when only one blower is being driven is automatically translated into fuel savings and/or increased cooling capacity.
