[0002] Saturation diving is the latest achievement in the development of diving technology. It not only has a diving depth and diving time that cannot be compared with conventional diving methods, but also has higher diving operation efficiency and safety, and has a wide range of applications in rescue and salvage and ocean engineering.

[0003] The environmental control unit of the saturation diving pressure chamber is an important supporting equipment for the saturation diving pressure chamber used in deep-sea development. It can realize the control of the gas environment in the pressure chamber. Its main functions are: adjusting the temperature and humidity in the chamber, removing harmful gases in the chamber. A set of safe and reliable environmental control system is essential for the saturation diving pressure chamber. In terms of the environmental control type, the environmental control unit of the saturation diving pressure chamber mainly has two types: external circulation type and internal circulation type.

[0004] Currently, in the prior art, it mainly focuses on aspects such as the system design, position layout, and component optimization of the environmental control unit of the saturation diving pressure chamber. However, if the environmental control unit is directly applied without overall verification and analysis, it may lead to the situation that the environmental control unit does not meet the requirements of various operating conditions of the saturation diving pressure chamber, resulting in the temperature and humidity, air quality, and uniform distribution of the air field in the chamber not meeting the operating requirements, and affecting the comfort and safety of divers in the chamber.
