This invention discloses a device and method for coordinated control of temperature and humidity in an oxygen chamber, belonging to the field of environmental regulation technology. The device includes a shell, a humidification module, a wet curtain, a drive module, and a floating component. The shell has a first air outlet, and a fan is fixedly installed inside the shell.
