[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 5 As shown, the dehumidification and reheat coil provided by the utility model includes a body 1, and the two sides of the body 1 are respectively connected with an air inlet 2 and an air supply port 3, and the surfaces of the air inlet 2 and the air supply port 3 are both provided with a dust removal structure 4, and the evaporator 5 is fixedly connected to the side of the body 1 near the air inlet 2, and the output end of the evaporator 5 is connected with the reheat evaporator 6, and the surface of the reheat evaporator 6 is fixedly connected to the body 1, and the bottom of the body 1 is fixedly connected with a water receiving pan 7, and the water dividing ends of the evaporator 5 and the reheat evaporator 6 are respectively connected with the evaporator water separator 8 and the reheat water separator 9, and the evaporator water separator 8 and the reheat water separator 9 are both used in conjunction with the water receiving pan 7, and the interior of the other side of the body 1 is fixedly connected with a blower 10, and the output end of the blower 10 is connected to the air supply port 3, and a controller 11 is fixedly connected to one side of the body 1.

[0022] refer to Figure 1 、 Figure 2 and Figure 4 The dust removal structure 4 includes two mounting frames 401, which are respectively mounted on the outside of the air inlet 2 and the air outlet 3. A dustproof frame 402 is snapped onto the inside of the mounting frame 401, and a dustproof net 403 is fixedly connected to the inside of the dustproof frame 402.

[0023] As a technical optimization solution of the present invention, by setting up the installation frame 401, the dustproof frame 402 and the dustproof net 403, the air circulating at the air inlet 2 and the air supply port 3 can be filtered, thereby reducing the dust from entering the interior of the body 1, thereby extending the service life of the dehumidification and reheat coil.

[0024] refer to Figure 4 The cross-sectional areas of the two dustproof nets 403 are respectively larger than the cross-sectional areas of the air inlet 2 and the air outlet 3 .

[0025] As a technical optimization solution of the present invention, by setting the cross-sectional areas of the two dustproof nets 403 to be larger than the cross-sectional areas of the air inlet 2 and the air supply outlet 3, it can be ensured that the air entering the air inlet 2 and the air supply outlet 3 can be filtered by the dustproof nets 403, thereby improving the dust-proof effect thereon.

[0026] refer to Figure 5 The surface of the mounting frame 401 is provided with four positioning grooves 404, and the four positioning grooves 404 are symmetrically arranged in groups of two. The surface of the mounting frame 401 is provided with four positioning holes 405, and the four positioning holes 405 are respectively in a one-to-one correspondence with the four positioning grooves 404. The interior of the positioning hole 405 is rotatably connected to a threaded column 406 through a micro bearing. The surface of the threaded column 406 is threadedly connected to a column sleeve 407, and the surface of the column sleeve 407 is slidably connected to the positioning hole 405 and is clamped with the positioning groove 404.

[0027] As a technical optimization solution of the present invention, through the arrangement of the positioning groove 404, the positioning hole 405, the threaded column 406 and the column sleeve 407, the threaded column 406 can be rotated to drive the column sleeve 407 to translate into the positioning groove 404, so that it can be stuck in the positioning groove 404, and then the position of the dust frame 402 can be fixed to prevent it from loosening during use. Then, it is only necessary to rotate the threaded column 406 in the opposite direction to move the column sleeve 407 out of the positioning groove 404, which makes it convenient for the staff to pull out the dust frame 402, thereby facilitating the cleaning of the dust net 403. At the same time, in this process, the threaded column 406 will not be separated from the positioning hole 405 and cause it to be lost.

[0028] refer to Figure 5 The surface of the column sleeve 407 is fixedly connected to the limiting block 408 , and the surface of the positioning hole 405 is provided with a limiting groove 409 , and the limiting groove 409 is slidably connected to the limiting block 408 .

[0029] As a technical optimization solution of the present invention, the setting of the limit block 408 and the limit groove 409 can prevent the column sleeve 407 from rotating as the threaded column 406 rotates, thereby ensuring that the column sleeve 407 can perform smooth linear motion.

[0030] refer to Figure 1 and Figure 2 One side of the water receiving tray 7 is connected to a drain valve.

[0031] As a technical optimization solution of the present invention, the setting of the drain valve makes it easy for staff to discharge the water collected in the water tray 7 to a designated location, thereby preventing the water from being retained in the water tray 7 and causing water overflow to pollute the environment.

[0032] The working principle and usage process of the present invention: When in use, first install the dehumidification and reheat coil to the designated position, then connect the drain valve to the external drainage system, then connect the dehumidification and reheat coil to the external power supply, and then preset the temperature of the exhaust air through the controller 11. When the machine is working, the blower 10 is started to generate a certain negative pressure, and the outdoor air is introduced into the body 1 through the air inlet 2. At this time, the outdoor wind is filtered by the dustproof net 403 when entering, so as to achieve the dust-proof effect. Then, after the outdoor wind passes through the evaporator 5 and is condensed, the waste heat in the control is collected by the evaporator water separator 8. Then, when the cold air passes through the reheat evaporator 6, the system will collect the waste heat and send it into the reheat evaporator 6 through the reheat water separator 9 to heat the cold air. After reaching the preset temperature, it will pass through the blower 10 and be sent to the designated area through the air outlet 3.
