Abstract

A refrigeration system for use in a refrigerator unit, the refrigeration system including a compressor having an ON state and an OFF state, a condenser, a temperature sensor, an evaporator, and an evaporator fan motor assembly. The evaporator fan motor assembly has an evaporator fan motor, a fan blade, and an internal control system. The internal control system of the evaporator fan motor assembly is adapted to sense the compressor state and is further adapted to operate the evaporator fan motor in response to the sensed compressor state. The refrigeration system may further include a condenser fan motor assembly. The condenser fan motor assembly has a condenser fan motor, a fan blade, and an internal control system. The internal control system of the condenser fan motor is adapted to sense the compressor state and is further adapted to operate the condenser fan motor in response to the sensed compressor state.
