That is, the device has a double structure in which an easily removable inner chamber 2 is installed inside an outer chamber 1 capable of independently maintaining an internal environment below freezing.

The inner chamber 2 is installed inside the outer chamber 1, and is configured to implement an artificial frost environment for a predetermined plant.

The inner chamber 2 is connected to the saturated air generator 7 through an air supply duct 5 and an exhaust duct 6 so that air with high humidity is circulated.

The wall 3 of the inner chamber 2 is made of a material such as metal that can conduct heat well, and an observation window 4 for observing the occurrence of frost inside can be appropriately applied.

The saturated air generator 7 is configured to generate, supply, and circulate air for generating artificial frost inside the inner chamber 2, which will be described later.

The principle of generating frost in the device is to circulate air by the saturated air generating unit 7 while maintaining the temperature of the outer chamber 1 at a sub-zero condition, and the temperature of the environment of the inner chamber 2 is changed to the outer chamber. Keep it slightly higher than (1), make the humidity close to saturation, and then stop the circulation of air.

In the state where all the air flow inside the inner chamber 2 is stagnant, the air close to saturation is condensed in the process of gradually cooling the inner chamber back to the same temperature as the outer chamber by the wall of the inner chamber having a high heat transfer effect. It reaches a dew point and causes frost to occur. The amount of artificial frost can be controlled by the temperature difference between the outer chamber and the inner chamber or the humidity of the saturated air that creates the inner environment.

It is sucked in and blown out of the surface by the bubble generator (7-5) to create mist-free, high-humidity air.

The temperature of the aqueous solution is controlled by the solution heater 7-6 so as to have an appropriate water content according to the concentration of the aqueous solution, and an eliminator 7-8 is installed at the discharge port so that the aqueous solution does not scatter.

The temperature and humidity sensor (7-9) installed at the inlet of the air in the inner chamber adjusts the speed of the blower (7-3) so that the air in the inner chamber does not rise excessively to maintain the temperature according to the air volume. It serves to stop the operation of the generator.

The supply of excessive moisture can be restricted through the operation and stop of the air pump 7-4 for bubble generation by the humidity sensor 7-11 of the discharge port.

The temperature sensor 7-10 that detects the temperature of the solution inside the water tank of the humidifier 7-2 controls the heating of the solution to adjust the moisture content of the bubbles. When moisture is insufficient in the humidifier, continuous humidification can be achieved by applying a water supply line (7-12) capable of supplying moisture.
