PHASE DETECTION METHODS, APPARATUS, AND SYSTEMS FOR TRANSPORT REFRIGERATION SYSTEM

Title:

PHASE DETECTION METHODS, APPARATUS, AND SYSTEMS FOR TRANSPORT REFRIGERATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2011/028514

Kind Code:

A3

Abstract:

Transport refrigeration systems such as container refrigeration systems can operate on 3-phase power supplied by an external power supply such as in storage when powered by a generator system. If the refrigeration system is equipped with 3-phase motors, it is necessary to provide a phase detection and adjustment capability to the refrigeration system if the rotational direction of these motors is relevant to the operation of the refrigeration system. Embodiments according to the application provide systems and method for phase detection in a refrigeration system.
