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 COscrubber. The COscrubber includes a metal organic framework (MOF) configured to adsorb COfrom 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 COscrubber, COfrom the air, and operating the TRS in a second mode that regenerates the MOF with ambient air.

A dehumidifying air handling unit for an HVACR system includes a housing, a desiccant wheel, and a cooling heat exchanger. A main airflow path extending through the housing from an air inlet to and air discharged outlet of the housing. The desiccant wheel includes a first end and a second end that are each disposed in the main airflow path and a metal organic framework desiccant that is moved between the first end and the second end. A desiccant wheel includes a metal organic framework desiccant disposed on a surface of the desiccant wheel. Rotation of the desiccant wheel moves a position of the surface between a first end and a second end of the desiccant wheel. The metal organic framework desiccant has an majority absorption-desorption operating band of 25% relative humidity or less.
