3、 Detailed technical performance and configuration of the equipment:

（1） Overall requirements for cabin design

The overall frame of the pressurized cabin is made of Q355R welded together, and the cabin plate is made of Q355R special container steel plate. After milling, it is processed using advanced double-sided groove automatic welding technology, and reinforced ribs are welded internally. The appearance treatment process is as follows:

1. Thoroughly remove rust using sandblasting and shot blasting technology;

2. Apply anti rust paint for rust prevention treatment;

3. Apply putty and polish smooth;

4. Use car spray painting technology to spray three coats of car paint;

（2） Equipment functions

1. Control system

(1) Cabin menu based intelligent control module: The cabin control system adopts an embedded structure touch based intelligent control panel. Users can select the desired operating mode through the menu based operation interface. The system will automatically operate the cabin according to preset programs, including pressurization, stabilization, oxygen supply, carbon dioxide concentration, temperature, and lighting parameters under all operating conditions.

(2) Power control module: The power control system adopts an embedded structure microcomputer touch control panel, installed on one side of the power box or at the cabin door outside the cabin. All display instruments and operation control components of the equipment are arranged on the panel, which can realize centralized start control and monitoring of all operating parameters of the equipment. The power control system can achieve intelligent control and automated operation of supporting equipment such as air compressors, oxygen concentrators, and oxygen boosters based on the operation instructions issued by the touch screen control panel inside and outside the cabin.

(3) Communication control module: There is an intercom module on one side of the cabin door or power cabinet outside the cabin. Personnel inside the cabin can talk to each other and make calls to those outside the cabin.

(4) To improve the safety performance of the equipment, two sets of manually operated valves are installed inside and outside the cabin to ensure that the emergency pressure relief to 10kPa in any working mode does not exceed 60 seconds, ensuring the safe use of the equipment.

2. Pressure regulation system

The pressure regulation system uses three vortex type oil-free air compressors for pressurization, and the cooled and filtered air is buffered by an air storage tank and enters the cabin.

To ensure the safety of equipment use, there are 2 sets of emergency pressure relief valves installed inside and outside the cabin. In case of emergency, the emergency pressure relief valves can be used to quickly evacuate personnel from the cabin, fully ensuring the safety of the equipment.

3. Oxygen supply and cabin environment gas circulation control system

The cabin adopts a saturated oxygen supply method with earphones and face shields. The oxygen supply system is equipped with three 20L oxygen generators for oxygen production, which can fully meet the needs of oxygen supply.

(1) Ear mounted oxygen supply: Oxygen is delivered from the oxygen supply pipeline to the oxygen terminal interface inside the cabin and inserted into a nasal suction oxygen inhalation device for oxygen inhalation. Can provide oxygen therapy for 4 people simultaneously.

(2) Mask saturation type: Equipped with an oxygen mask, it can provide oxygen saturation for two people at the same time.

Note: Up to 3 people can receive oxygen from the mask simultaneously (not from the headset at the same time).

(3) To ensure safe use, the equipment is designed in accordance with the GB/T12130-2005 standard for medical air pressurized oxygen chambers. The oxygen concentration inside the chamber is always controlled within 23%, and the carbon dioxide concentration is controlled within the comfortable range of the human body. To ensure that all gas data is normal, the control module will automatically ventilate and exchange air after the equipment runs according to the program. The ventilation rate reaches 46.8 m ³/h to ensure that the oxygen concentration and carbon dioxide concentration inside the chamber meet the requirements of rehabilitation and environmental gas safety control indicators.

4. Cabin environment regulation system

To ensure the normal use of the equipment, the cabin is equipped with an air conditioning system, which can independently control the temperature through the air conditioning control panel.

5. Variable light illumination system

The cabin lighting system can achieve stepless brightness adjustment, fully meeting the needs of user treatment and cabin atmosphere creation. The menu based intelligent control module of the system runs automatically according to program settings.

6. Electrical system

This system adopts an AC 220V 50Hz power supply system, which is connected to the equipment's dedicated distribution cabinet through the power grid. The input power supply should meet 10KW (including air conditioning).
