Abstract
A transport refrigeration system (TRS) for an enclosed space of a transport unit that includes a ventilation pathway to direct air to flow from the enclosed space. The TRS includes a refrigerant circuit with an evaporator configured to cool the air, and a CO2 scrubber. The CO2 scrubber includes a metal organic framework (MOF) configured to adsorb CO2 from the air in an adsorption mode and is regenerated with ambient air in a regeneration mode. A transport unit includes an enclosed space for storing produce, a ventilation pathway, and a TRS. A method of conditioning an enclosed space of a transport unit includes operating a TRS in a first mode that cools air from the enclosed space and adsorbs, with a MOF in a CO2 scrubber, CO2 from the air, and operating the TRS in a second mode that regenerates the MOF with ambient air.
