[0002] Dynamic ice storage is a system that uses ice storage technology to store and release cold air. It is commonly used in air conditioning and refrigeration systems to balance energy demand and improve energy efficiency. The principle of this technology is to use the latent heat absorbed or released during the crystallization and melting of ice. The purified fresh air system introduces fresh air from outdoors into the room, and at the same time removes pollutants in the air through filtration and purification, providing clean and healthy indoor air.

[0003] The existing dynamic ice storage purified fresh air is achieved by placing the exchanger in the cold air duct. The fresh air enters the cold air duct, and the ice slurry in the ice storage cabinet is pumped into the exchanger by a water pump. The fresh air after heat exchange is output from the upper side of the cold air duct into the cooling space.

[0022] like Figure 1-Figure 3 As shown, the water removal mechanism 9 includes a motor 91, a screw rod 92, a scraper 93 and a guide rod 94. Four motors 91 are connected to the middle part of the cold air duct 3. The output shafts of the motors 91 are connected to screw rods 92. The screw rods 92 are rotatably connected to the cold air duct 3. The screw rods 92 are located inside the cold air duct 3. Scrapers 93 are threadedly connected to the screw rods 92. The scrapers 93 are in contact with the cold air duct 3. Four guide rods 94 are connected to the inside of the cold air duct 3. The guide rods 94 are slidably connected to adjacent scrapers 93.

[0023] When using the present device, first place the support frame 1 in the fresh air purification area, then start the fresh air fan 2, so that the fresh air enters the cold air duct 3, and at the same time start the water pump 6. The water pump 6 operates so that the ice slurry in the ice storage cabinet 5 is pumped into the exchanger 8. The dynamic ice slurry circulating in the pipe of the exchanger 8 is the cold source, and the fresh air in the cold air duct 3 is the heat source. The fresh air after heat exchange is output from the upper side of the cold air duct 3 into the cooling space, and then the water discharge frequency of the timing solenoid valve 40 can be adjusted according to the air volume, so that the condensed water generated on the wall of the exchanger 8 enters the ice storage cabinet 5 through the recovery pipe 4 for reuse. When the present device is used for a long time and water mist is attached to the inner wall of the cold air duct 3, the motor 91 can be started to drive the screw rod 92 to rotate, so that the scraper 93 moves up and down along the guide rod 94 under the action of the thread, and then the condensed water on the inner wall of the cold air duct 3 enters the ice storage cabinet 5 for reuse through the recovery pipe 4, so that the condensed water on the inner wall of the cold air duct 3 can be scraped off, the air circulation is improved, and the equipment is prevented from being damaged.

[0025] When the anti-backflow mechanism 10 of the present device is used, the condensed water can be prevented from flowing back into the fresh air fan 2. When there is too much condensed water, the handle 105 can be rotated to make the water reservoir 104 rotate under the action of the thread, driving the baffle 103 to rotate, so that the condensed water enters the water reservoir 104 through the funnel 101. The water reservoir 104 is made of transparent material, which is convenient for observing the water amount in the water reservoir 104. The water discharge frequency can be adjusted in time through the timing solenoid valve 40, so as to prevent the condensed water from flowing back into the fresh air fan 2 and avoid damage to the fresh air fan 2. When the present device is no longer used, the handle 105 can be rotated to make the water reservoir 104 rotate through the thread, thereby making the water reservoir 104 disengage from the connecting piece 102, and the condensed water is caught by the container, and then the handle is held to open the ice storage cabinet 5, and the condensed water is poured into the ice storage cabinet 5 for recycling.
