AIR CONDITIONING AND REFRIGERATION SYSTEM AND METHOD FOR CONTAINER EQUIPPED WITH A TRANSPORT REFRIGERATION UNIT

An air conditioning and refrigeration system (100) for a container (102) equipped with a transport refrigeration unit (TRU) (104) is disclosed. The system (100) comprises a variable speed fan (108) configured with the TRU (104), and one or more first sensors (110-1) positioned at predefined positions at a rear section (106-1) of a conservation space (106) associated with the container (102). The one or more first sensors (110-1) are configured to monitor one or more first attributes associated with the rear section (106-1). The system (100) further comprises a controller (202) in communication with the one or more first sensors (110-1) and the fan (108). The controller (202) is configured to adjust speed of the fan (108) and/or adjust cooling capacity of the TRU (104) based on the monitored first attributes of the rear section (106-1), to maintain a predefined environment at the rear section (106-1) or across the conservation space (106).
