Title
(EN) TRANSPORTATION REFRIGERATION UNIT WITH EXTERNAL AC GENERATOR POWER SOURCE
(FR) UNITÉ DE RÉFRIGÉRATION DE TRANSPORT AVEC SOURCE D'ALIMENTATION DE GÉNÉRATEUR DE COURANT ALTERNATIF EXTERNE
Abstract
(EN)
A transportation refrigeration unit TRU (26) and power system. The TRU (26) and power system including a compressor (58) configured to compress a refrigerant, an evaporator heat exchanger (76) operatively coupled to the compressor (58), and an evaporator fan (98) configured to provide return airflow (134) and flow the return airflow (137) over the evaporator heat exchanger (76). The system also includes a return air temperature RAT sensor (142) disposed in the return airflow (134) and configured to measure the temperature of the return airflow (134), a TRU controller (82) operably connected to the RAT sensor (142) and configured to execute a process to determine an AC power requirement for the TRU (26) based on at least the RAT sensor (142); an alternating current AC generator (162) operably coupled to an axle or wheel hub, and configured to provide a first three phase AC power (163) to a power management system (124), the power management system (124) configured to direct power the TRU (26) based on the AC power requirement.

L'invention concerne également une unité de réfrigération de transport TRU (26) et un système d'alimentation. La TRU (26) et le système d'alimentation comprennent un compresseur (58) conçu pour comprimer un fluide frigorigène, un échangeur de chaleur d'évaporateur (76) fonctionnellement couplé au compresseur (58), et un ventilateur d'évaporateur (98) conçu pour fournir un flux d'air de retour (134) et faire circuler le flux d'air de retour (137) sur l'échangeur de chaleur d'évaporateur (76). Le système comprend également un capteur RAT de température d'air de retour (142) disposé dans le flux d'air de retour (134) et conçu pour mesurer la température du flux d'air de retour (134), un contrôleur de TRU (82) connecté de manière fonctionnelle au capteur RAT (142) et conçu pour exécuter un processus pour déterminer une exigence de puissance CA pour la TRU (26) sur la base d'au moins le capteur RAT (142) ; un générateur de courant alternatif CA (162) couplé de manière fonctionnelle à un axe ou à un moyeu de roue, et conçu pour fournir une première puissance CA triphasée (163) à un système de gestion d'énergie (124), le système de gestion d'énergie (124) étant conçu pour diriger de l'énergie à la TRU (26) sur la base de l'exigence de puissance CA.
