The CZK marine modular air conditioning unit serves as the core component of duct-supply marine central air conditioning systems. Primarily comprising a compressor-condenser unit, air handling enclosure, automated control valves, and electrical control assembly, it is mounted on a common baseplate. The unit provides refrigeration, heating, humidification, dehumidification, filtration, and fresh air exchange functions.

The air conditioning unit housing employs a novel modular assembly structure, offering advantages such as excellent sealing properties, minimal deformation, lightweight construction, superior noise reduction capabilities, and ease of installation and disassembly. For retrofitting onto existing vessels, the modular design allows the unit to be disassembled into individual components for transport to the designated compartment before reassembly. This eliminates the need for cutting into the original hull structure, significantly reducing shipyard workload and preventing compromise to the vessel's overall structural integrity.
