PROCÉDÉS ET SYSTÈMES DE COMMANDE D'ÉCOULEMENT DE FLUIDE DE TRAVAIL SUPPLÉMENTAIRE À L'AIDE D'UN CIRCUIT DE COMMANDE DE CLIMATISATION

摘要

A method for providing supplemental flow control of working fluid through a transport climate control circuit during a start-stop cooling operation mode is provided. The method includes closing (305) a main liquid suction solenoid valve (236) disposed between a condenser and an evaporator of the transport climate control circuit when the compressor is OFF. The method also includes monitoring (310) a climate controlled space temperature within a climate controlled space. When the climate controlled space temperature is greater than or equal to a predetermined setpoint temperature (315), the method includes turning a compressor ON (320), and opening (335) the main liquid suction solenoid valve when a suction pressure at the suction port of the compressor is less than or equal to a predetermined suction pressure threshold. When the climate controlled space temperature is less than or equal to the predetermined setpoint temperature (340), the method includes turning the compressor OFF (350), and closing (355) the main liquid suction solenoid valve.
