Description

Technical Field

[0001] The invention relates to an island-type fresh air system, in particular to a double-column island-type air ecological device. Background Art

[0002] With the development of modern industrial society, air pollution is becoming increasingly serious, and the number of suspended pollutants and suspended particles in the atmosphere is increasing. Air pollution has seriously threatened the living space of ordinary people. How to ensure indoor air quality has also become a topic of increasing concern. Currently, the quality of indoor air is mainly improved through fresh air unit systems.

[0003] At present, most of the fresh air units used in crowded spaces such as stations and service halls need to occupy machine room space. Since the units are installed in the machine room, they need to transport the treated fresh air from the machine room to the hall through pipes. The air supply pressure loss is large, reaching about 40%, and the air supply outlet is set on the side, resulting in a higher intermediate temperature in the hall during summer air supply and poor comfort for people. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a double-column island air ecological device with long air supply range and high comfort.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: a double-column island air ecological device, the innovation of which is: comprising

[0006] An outer shell, wherein a pair of inner cylinders with the same structure and vertical axes are built in the outer shell, and the space between the pair of inner cylinders and the outer shell forms an isolation chamber, and the inner chamber of the inner cylinder is divided into a surface cooling section, a muffler section, and a fan section from bottom to top along its own axis direction, and the surface cooling section at the bottom of the inner cylinder is connected to the bottom of the isolation chamber, the surface cooling section of the inner cylinder is built with an annular surface cooler, the muffler section of the inner cylinder is built with a muffler, and the fan section of the inner cylinder is built with a fan;

[0007] A top-layer air outlet box body is arranged at the top of the outer shell body, and a plurality of air outlets are distributed on the outer wall of the top-layer air outlet box body. The top-layer air outlet box body is equipped with a pair of static pressure chambers respectively located directly above the two inner cylinders, and the side walls of the static pressure chambers are connected with the air outlets on the corresponding sides through a plurality of independent air outlet branch pipes, and the bottom of the static pressure chamber is connected with the inner cavity of the fan section at the top of the inner cylinder body; the center of the top-layer air outlet box body is provided with an air inlet, and the air inlet is connected with the top center of the isolation chamber.

[0008] Preferably, the air outlet comprises a side air outlet and a bottom air outlet, a plurality of side air outlets are distributed on the outer side wall of the top air outlet box body, and a plurality of bottom air outlets are distributed near the edge on the lower surface of the top air outlet box body.

[0009] Preferably, the front and back sides of the outer shell are planar structures, and the side faces of the outer shell are arc-shaped structures that mimic the shape of the inner cylinder.

[0010] Preferably, an air volume balancing valve is installed on the air outlet branch pipe.

[0011] The advantages of the present invention are:

[0012] The island-type air ecological device of the present invention can be directly placed in a crowded area, which does not occupy the space of the machine room and avoids the pressure loss caused by ducted air supply. The air supply range is long and the comfort is high.

[0013] In the present invention, an isolation cavity is formed between the inner and outer cylinders, and the top return air enters the isolation cavity from the center of the top air outlet box to recover the hot air in the upper space, thereby preventing the bottom return air from directly recovering the cold air. After the hot air enters the isolation cavity, it first contacts the outer walls of the two inner cylinders for pre-cooling, thereby reducing the temperature and dehumidifying, thereby preventing frost from being caused by the exchange of excessive refrigerant with hot air in the surface cooler, thereby eliminating the defrosting process and realizing the continuous operation of the island-type air fresh air system.

[0014] The cold air in the inner tube does not come into direct contact with the outside world after heat exchange, which prevents the temperature near the outer tube from being too low, causing regional temperature differences; at the same time, it can prevent condensation on the surface of the outer tube from causing moisture on the ground. In addition, the double inner tubes are symmetrically arranged so that the top-floor return air can be evenly distributed in the isolation cavity for uniform cooling and dehumidification.

[0020] like Figures 1 to 5 As shown, the double-column island air ecological device of the present invention includes an outer shell 1, an inner cylinder 2, a top-layer air outlet box 3, and an isolation chamber 4.

[0021] A pair of inner cylinders 2 with the same structure and vertical axes and arranged side by side are built into the outer shell 1. The space between the inner cylinders 2 and the outer shell 1 forms an isolation chamber 4. In this embodiment, the front and back of the outer shell 1 are planar structures, and the side of the outer shell 1 is an arc-shaped structure that imitates the inner cylinder 2. The cross-section of the isolation chamber 4 is approximately an "8" shape.

[0022] The inner cavity of the inner cylinder 2 is divided into a surface cooling section 21, a silencer section 22, and a fan section 23 from bottom to top along its own axial direction. The surface cooling section 21 at the bottom of the inner cylinder 2 is connected to the bottom of the isolation chamber 4. The surface cooling section 21 of the inner cylinder 2 is equipped with an annular surface cooler, the silencer section 22 of the inner cylinder 2 is equipped with a silencer, and the fan section 23 of the inner cylinder 2 is equipped with a fan.

[0023] The top air outlet box 3 is arranged at the top of the outer shell 1, and a plurality of air outlets are distributed on the outer wall of the top air outlet box 3. In this embodiment, its outer contour is similar to that of the outer shell 1, but its size is larger than that of the outer contour of the outer shell 1. The air outlets include side air outlets 71 and bottom air outlets 72. A plurality of side air outlets 71 are distributed on the outer wall of the top air outlet box 3, and a plurality of bottom air outlets 72 are distributed near the edge of the lower surface of the top air outlet box 3. The top air outlet box 3 is built with a pair of circular static pressure chambers 5 located directly above the two inner cylinders, respectively. The side walls of the static pressure chambers 5 are connected to the air outlets on the corresponding sides through a plurality of independent air outlet branches 6, and the bottom of the static pressure chamber 5 is connected to the inner cavity of the fan section 23 at the top of the inner cylinder 2. An air volume balancing valve is installed on the air outlet branch 6.

[0024] An air inlet 8 is provided at the center of the top air outlet box 3 , and the air inlet 8 is connected to the top center of the isolation cavity 4 .

[0025] Working principle:

[0026] The top return air enters the top of the isolation cavity through the air inlet in the center of the top air outlet box. The hot air of the top return air is evenly distributed in the isolation cavity during the downward process, and exchanges heat with the cooled cold air in the two inner cylinders through the inner cylinders to reduce temperature and dehumidify. The pre-cooled return air enters the surface cooling section of the inner cylinder from the bottom of the isolation cavity, and after being cooled by the annular surface cooler, it passes through the silencer section and the fan section and enters the static pressure cavity. The static pressure cavity reduces noise and obtains uniform static pressure outlet, which is discharged from the side outlets and the bottom outlet.
