Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology, specifically to a waste heat recovery and utilization device for central air conditioning. Background Technology

[0002] Central air conditioning waste heat recovery and utilization device is an environmentally friendly and energy-saving device that recovers the waste heat emitted by the air conditioning system to achieve energy reuse. When the air compressors of the central air conditioning are centrally installed and running, the heat emitted by the air compressors to the outside is recovered and then reused to heat water. This not only reduces the operating pressure of the air conditioning equipment and reduces the energy consumption of the air conditioning equipment, but also recovers and utilizes waste heat.

[0003] However, the utilization rate of existing central air conditioning waste heat recovery devices needs to be improved. During the recovery process, because cold water is constantly circulating inside the pipes, water droplets easily form on the outer wall of the pipes due to the temperature difference, which reduces the heating effect of the discharged heat on the pipes and reduces the heating efficiency of the waste heat. Utility Model Content

[0004] The purpose of this utility model is to address the problems mentioned above, such as the need to improve the utilization rate of waste heat recovery from air conditioning, and the easy formation of water droplets on the outer wall of the pipe, which reduces the heating effect of the discharged heat on the pipe and reduces the heating efficiency of waste heat. This utility model provides a waste heat recovery and utilization device for central air conditioning.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A central air conditioning waste heat recovery and utilization device includes a casing. An arched frame is slidably connected to the inside of the casing. Limiting posts are fixedly installed at the bottom ends of the left and right sides of the arched frame. The limiting posts are inserted into the inside of the casing with downward limiting. A pad is fixedly installed at the bottom of the inside of the casing. The pad is located below the left and right sides of the arched frame. A baffle is fixedly installed at the middle of the top of the arched frame. A spiral tube is fixedly installed on the inner side of the top of the arched frame. Folded tubes are fixedly installed on the inner sides of the left and right sides of the arched frame. The two ends of the folded tubes are fixedly connected to the spiral tubes and communicate with the spiral tubes. A lifting assembly is provided between the folded tubes on the left and right sides and the inner wall of the casing.

[0007] Furthermore, the arched frame adopts a mesh-like double-layer design, with the spiral tube and folded tube located between the double-layer mesh frame to ensure stable installation of the spiral tube and folded tube.

[0008] Furthermore, the contact points between the top of the pad and the bottom of the left and right sides of the arched frame are made of rubber to avoid rigid contact between the arched frame and the pad.

[0009] Furthermore, the baffle is located in the upper region of the top of the arched frame, which can block the upward-blowing hot air while not preventing the hot air from contacting the spiral tube.

[0010] Furthermore, the lifting assembly includes mounting columns, with mounting columns fixedly installed on the left and right sides inside the chassis. Mounting tubes are fixedly installed on the side of each mounting column closest to the inner wall of the chassis, and the mounting tubes extend vertically through the mounting columns. The top of each mounting tube is bent towards the side closest to the inner wall of the chassis, and a connecting seat is fixedly installed on the top of each mounting tube. The connecting seat extends through the inner wall of the chassis. Flexible hoses are fixedly connected between the bottom of each mounting tube on both sides and the folded tube. A telescopic rod is slidably connected to the bottom of each mounting column, and a spring is fixedly connected between the top of the telescopic rod and the inner wall of the mounting column. A roller is rotatably connected to the bottom of the telescopic rod, and the flexible hose passes around the bottom of the roller.

[0011] Furthermore, the top of the chassis is provided with an exhaust vent, and the left and right sides of the chassis are provided with side windows, each of which is fixedly equipped with a protective net.

[0012] Furthermore, the spiral tube is aligned with the exhaust vent and is located above the exhaust fan inside the chassis. The folded tubes on the left and right sides are aligned with the side windows, so that both the spiral tube and the folded tube are located at the exhaust point of the hot air inside the chassis.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention, through the design of the position and shape of the spiral tube and folded tube, can interact with all the hot air exhaust points of the casing and increase the contact area with the hot air, thereby improving the utilization rate of waste heat recovery from air conditioning. By utilizing the cooperation of the arched frame and the lifting component, when the central air conditioning is running intermittently via frequency conversion, the arched frame can move up and down intermittently, and with the help of pads, shake off the water droplets condensed on the outer wall of the spiral tube and folded tube, preventing the water droplets from affecting the heating of the spiral tube and folded tube by the hot air, thus improving the heating efficiency of waste heat.

[0025] A preferred embodiment of the present invention, a central air conditioning waste heat recovery and utilization device, will be described in detail below, such as... Figures 1-5 As shown, a central air conditioning waste heat recovery and utilization device includes a casing 1. An arched frame 2 is slidably connected inside the casing 1. The arched frame 2 adopts a double-layer mesh design. The spiral pipe 6 and the folded pipe 7 are located between the double-layer mesh to stably install the spiral pipe 6 and the folded pipe 7. Limiting posts 3 are fixedly installed at the bottom of the left and right sides of the arched frame 2. The limiting posts 3 are inserted into the inside of the casing 1 to limit the downward movement, thereby realizing the limiting sliding connection of the arched frame 2 inside the casing 1.

[0026] A pad 4 is fixedly installed at the bottom of the inside of the casing 1. The top of the pad 4 is made of rubber at the contact point with the bottom of the left and right sides of the arched frame 2 to avoid rigid contact between the arched frame 2 and the pad 4. The pad 4 is located below the left and right sides of the arched frame 2. A baffle 5 is fixedly installed in the middle of the top of the arched frame 2. The baffle 5 is located in the upper area of ​​the top of the arched frame 2. It can block the upward blowing hot air while not preventing the hot air from contacting the spiral tube 6. A spiral tube 6 is fixedly installed on the inner side of the top of the arched frame 2. Folded tubes 7 are fixedly installed on the inner sides of the left and right sides of the arched frame 2. The two ends of the folded tubes 7 are fixedly connected to the spiral tubes 6 and communicate with the spiral tubes 6 to realize the circulation of water inside the folded tubes 7 and the spiral tubes 6.

[0027] The top of the chassis 1 is provided with an exhaust vent 9, and the left and right sides of the chassis 1 are provided with side windows 10. Protective nets are fixedly installed at each side window 10. The spiral pipe 6 is aligned with the exhaust vent 9 and is located above the exhaust fan inside the chassis 1. The left and right folding pipes 7 are aligned with the side windows 10, so that the spiral pipe 6 and the folding pipes 7 are located at the exhaust point of the hot air inside the chassis 1.

[0028] Furthermore, such as Figure 2 , Figures 6-8 As shown, a lifting assembly 8 is provided between the left and right folding tubes 7 and the inner wall of the chassis 1. The lifting assembly 8 includes a mounting column 81. Mounting columns 81 are fixedly installed on the left and right sides inside the chassis 1. Mounting tubes 82 are fixedly installed on the side of the mounting column 81 closest to the inner wall of the chassis 1. The mounting tubes 82 pass through the mounting column 81 vertically. The top of the mounting tube 82 is bent towards the side closest to the inner wall of the chassis 1. A connecting seat 83 is fixedly installed on the top of the mounting tube 82. The connecting seat 83 passes through the inner wall of the chassis 1. Flexible hoses 84 are fixedly connected between the bottom of the mounting tubes 82 on both sides and the folding tubes 7. A telescopic rod 85 is slidably connected to the bottom of the mounting column 81. A spring 86 is fixedly connected between the top of the telescopic rod 85 and the inner wall of the mounting column 81. A roller 87 is rotatably connected to the bottom of the telescopic rod 85. The flexible hose 84 passes around the bottom of the roller 87.

[0029] The working principle of this utility model is as follows:

[0030] During assembly, the circulation pipes in the hot water heating system are fixedly connected to the connecting seats 83 on both sides. Therefore, during use, the water can enter the folded pipe 7 through the connecting seat 83 on one side, and then flow out from the connecting seat 83 on the other side after passing through the spiral pipe 6 and the folded pipe 7 on the other side, thereby realizing the circulation of water inside the spiral pipe 6 and the folded pipe 7.

[0031] During the water flow, the installation of the spiral pipe 6 and the folded pipe 7 using the arched frame 2, and the alignment of the spiral pipe 6 with the exhaust port 9 and the folded pipe 7 with the side window 10, ensure that both the spiral pipe 6 and the folded pipe 7 are located at the heat exhaust point inside the casing 1. Therefore, when the central air conditioning is running and the casing 1 is working and exhausting heat, the spiral pipe 6 and the folded pipe 7 can be heated, thereby continuously heating the flowing water and realizing the recovery and utilization of waste heat from the central air conditioning.

[0032] By designing the position and shape of the spiral tube 6 and the folded tube 7, they can interact with all the hot air exhaust points of the casing 1 and increase the contact area with the hot air, thereby improving the utilization rate of waste heat recovery from air conditioning.

[0033] When the chassis 1 exhausts air upwards from the exhaust port 9 through the exhaust fan, the baffle 5 can block the hot air, allowing the hot air to better heat the spiral tube 6. At the same time, the baffle 5 can also drive the arched frame 2 to move upwards under the action of the airflow. During the upward movement of the arched frame 2, the folded tubes 7 on the left and right sides can pull the hose 84 upwards, causing the hose 84 to drive the roller 87 and the telescopic rod 85 to compress the spring 86 upwards. During the pulling process, the hose 84 can remain taut to ensure the normal flow of water.

[0034] When the central air conditioner operates intermittently via frequency conversion, the casing 1 also operates intermittently. Therefore, when the casing 1 stops exhausting air, the baffle 5 is no longer subjected to upward thrust. The telescopic rod 85, under the restoring force of the spring 86, pushes the hose 84 downward through the roller 87, thereby causing the folded pipe 7 and the arched frame 2 to move downward. During the downward movement of the arched frame 2, the bottom ends on both sides of the arched frame 2 will collide with the pad 4, thereby shaking off the water droplets condensed on the outer walls of the spiral pipe 6 and the folded pipe 7. Therefore, when the central air conditioner operates intermittently, the water droplets on the outer walls of the spiral pipe 6 and the folded pipe 7 can be removed, preventing the water droplets from affecting the heating of the spiral pipe 6 and the folded pipe 7 by the hot air.

[0035] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
