Description

Technical Field

[0001] This utility model relates to the field of heating, ventilation and air conditioning technology, specifically to a heat pump type total heat recovery fresh air conditioning unit. Background Technology

[0002] A heat pump-type total heat recovery fresh air conditioning unit is an integrated air conditioning device that combines heat pump cycle technology, total heat recovery technology, and fresh air handling functions. Through the synergistic design of "energy cascade utilization + active fresh air replacement," it continuously supplies fresh air that has undergone temperature, humidity regulation, and purification treatment to the indoor environment while efficiently recovering the total heat of the indoor exhaust air to reduce energy consumption. It is widely used in residential buildings, commercial buildings, industrial plants, and other scenarios with high demand for fresh air and a focus on energy consumption control.

[0003] However, in practical applications, during fresh air replacement in winter, the alternation of hot and cold air can easily cause water droplets to condense on the outer surface of the pipes. When the ambient temperature drops below 10 degrees Celsius, these condensed water droplets will freeze into ice on the outer surface of the pipes, thus hindering the heat transfer of the pipes and affecting the overall heat exchange efficiency of the unit. Therefore, it is necessary to provide a heat pump type total heat recovery fresh air conditioning unit. Utility Model Content

[0004] The purpose of this utility model is to provide a heat pump type total heat recovery fresh air conditioning unit to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution: This utility model relates to a heat pump type total heat recovery fresh air conditioning unit, comprising: Air conditioning units; The water-absorbing component includes a fixed bracket connected to the pipe inside the air conditioning unit, a servo motor screwed to the fixed bracket, a long lead screw fixed to the end of the servo motor, a first bearing sleeved and welded to the end of the long lead screw, and a slider connected through the first bearing.

[0005] Furthermore, the water-absorbing component also includes a semi-circular mounting block screwed to the bottom of the slider and an annular metal pressure plate screwed to the end of the pipe.

[0006] Furthermore, the water-absorbing component also includes a rectangular groove in the center of one side of the semi-circular mounting block, a bolt that passes through and is fixed to the upper side of the semi-circular mounting block, a third bearing welded to the bolt, a connecting block welded to one side of the third bearing, and a semi-circular connecting ring welded to the center of one side of the connecting block.

[0007] Furthermore, the water-absorbing component also includes a sponge screwed onto a semi-circular connecting ring. The sponge is semi-circular and its inner side is attached to the outer surface of the internal pipe of the air conditioning unit.

[0008] Furthermore, there are two semi-circular mounting blocks, which are symmetrically attached to the outer surface of the internal pipe of the air conditioning unit, and both ends of the semi-circular mounting blocks are fitted and connected to the long rod screw.

[0009] Furthermore, it also includes a flow guiding component, which includes an L-shaped bracket screwed onto a fixed bracket, a water-holding plate screwed onto the L-shaped bracket, and a connecting block fixed to the end of the water-holding plate.

[0010] Furthermore, the flow guiding component also includes a threaded hole at one end of the connecting block, a metal pipe head screwed into the threaded hole, and a water pipe fixed around the inside of the metal pipe head, with the other end of the water pipe placed on the outside of the air conditioning unit.

[0011] Furthermore, the flow guiding component also includes a water-pressing convex surface welded to one side of the semi-circular connecting ring, and the water-holding plate is located at the lower end of the annular metal pressure plate.

[0012] This invention offers the following advantages: After the servo motor starts, it drives the long lead screw to rotate. The lead screw, through the first bearing, moves the slider, and the two symmetrical semi-circular mounting blocks at the bottom of the slider move along the outer surface of the pipe. Bolts on the semi-circular mounting blocks adjust the position of the sponge. Through the third bearing and rectangular connecting block, the semi-circular connecting ring and the sponge are brought close to the pipe. As the sponge moves with the mounting blocks, it adheres to the outer surface of the pipe, absorbing condensate and dust. During this movement, the sponge automatically cleans the outer surface of the pipe, reducing condensate residue and dust accumulation. This invention also solves the problem of water vapor forming when hot and cold elements meet during heat exchange, which is then condensed into ice by the cold air. This improves overall efficiency and avoids energy waste. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0018] Please see Figure 1-6 As shown, this utility model is a heat pump type total heat recovery fresh air conditioning unit, comprising: 10 air conditioning units; The water-absorbing component includes a fixed bracket 20 connected to the pipe inside the air conditioning unit 10, a servo motor 21 screwed to the fixed bracket 20, a long rod screw 22 fixed to the end of the servo motor 21, a first bearing 221 sleeved and welded to the end of the long rod screw 22, and a slider 222 connected through the first bearing 221. The air conditioning unit 10 is the main body, using the PHE02A-BA15P model, to realize the functions of heat pump type total heat recovery and fresh air conditioning; the fixed bracket 20 is used to install the water suction component, the servo motor 21 provides power to drive the long rod screw 22 to rotate, the long rod screw 22 drives the slider 222 to move through the first bearing 221, and the slider 222 provides moving support for other components.

[0019] The water-absorbing component also includes a semi-circular mounting block 23 screwed to the bottom of the slider 222 and an annular metal pressure plate 24 screwed to the end of the pipe; The semi-circular mounting block 23 is used to connect the slider 222 and the cleaning component, and the annular metal pressure plate 24 fixes and assists in the positioning of the semi-circular mounting block 23.

[0020] The water-absorbing component also includes a rectangular groove 231 opened in the center of one side of the semi-circular mounting block 23, a bolt 232 that passes through and is fixed to the upper side of the semi-circular mounting block 23, a third bearing 233 welded to the bolt 232, a rectangular connecting block 25 welded to one side of the third bearing 233, and a semi-circular connecting ring 26 welded to the center of one side of the rectangular connecting block 25. The rectangular groove 231 is used to install related components. The bolt 232 adjusts the position of the cleaning component and can adjust the distance between the sponge 27 and the pipe. The rectangular connecting block 25 connects the bolt 232 and the semi-circular connecting ring 26. The semi-circular connecting ring 26 is used to install the sponge 27.

[0021] The water-absorbing component also includes a sponge 27 screwed onto a semi-circular connecting ring 26. The sponge 27 is semi-circular and its inner side is attached to the outer surface of the inner pipe of the air conditioning unit 10. Sponge 27 adheres to the outer surface of the pipe to absorb condensation and dust.

[0022] There are two semi-circular mounting blocks 23, which are symmetrically attached to the outer surface of the inner pipe of the air conditioning unit 10, and both ends of the semi-circular mounting blocks 23 are fitted and connected to the long rod screw 22. Two symmetrical semi-circular mounting blocks 23 fit the pipe to ensure the outer surface of the pipe is clean.

[0023] Working principle: After the servo motor 21 starts, it drives the long rod screw 22 to rotate. The long rod screw 22 drives the slider 222 to move through the first bearing 221. The two symmetrical semi-circular mounting blocks 23 at the bottom of the slider 222 move along the outer surface of the pipe. The bolts 232 on the semi-circular mounting blocks 23 can adjust the position of the sponge 27. Through the third bearing 233 and the rectangular connecting block 25, the semi-circular connecting ring 26 and the sponge 27 are driven to come close to the pipe. As the sponge 27 moves with the mounting blocks, it adheres to the outer surface of the pipe to absorb condensate and dust. During the movement, the sponge 27 achieves automatic cleaning of the outer surface of the pipe, reducing condensate residue and dust accumulation.

[0024] This solution addresses the problem of water vapor forming when hot and cold air meet during heat exchange, which is then condensed into ice by the cold air, by incorporating a water-absorbing component. This improves overall efficiency and avoids energy waste.

[0025] After the sponge 27 is fully saturated with water, it is prone to freezing into ice cubes at low temperatures and will not be able to continue absorbing water. To address this issue, a reminder feature is included. Specifically, it also includes a flow guiding component, which includes an L-shaped bracket 30 screwed onto the fixed bracket 20, a water-holding plate 31 screwed onto the L-shaped bracket 30, and a trapezoidal connecting block 32 fixed to the end of the water-holding plate 31. The L-shaped bracket 30 fixes the water-collecting plate 31, which collects the water droplets squeezed out of the sponge 27. The trapezoidal connecting block 32 connects the water-collecting plate 31 and the drainage component.

[0026] The flow guiding component also includes a threaded hole 33 at one end of the trapezoidal connecting block 32, a metal pipe head 34 screwed into the threaded hole 33, a water pipe 35 fixed around the inner side of the metal pipe head 34, and the other end of the water pipe 35 placed on the outside of the air conditioning unit 10. A metal pipe head 34 is installed in the threaded hole 33. The metal pipe head 34 connects the water-holding plate 31 and the water pipe 35. The water pipe 35 discharges water to the outside of the unit.

[0027] The flow guiding component also includes a water-pressing convex surface 36 welded to one side of the semi-circular connecting ring 26, and the water-holding plate 31 is located at the lower end of the annular metal pressure plate 24. The water-pressing convex surface 36 squeezes the sponge 27 to drain the water, and the water-collecting plate 31 is located below the annular metal pressure plate 24 to facilitate water collection.

[0028] Working principle: When the water-pressing protrusion 36 on the semi-circular connecting ring 26 squeezes the sponge 27 to drain water, the water-collecting plate 31 collects the dripping water droplets; the trapezoidal connecting block 32 at the end of the water-collecting plate 31 installs a metal pipe head 34 through its own threaded hole 33, the metal pipe head 34 connects the water-collecting plate 31 and the water pipe 35, and finally the water pipe 35 discharges the collected water to the outside of the air conditioning unit 10.

[0029] This solution solves the problem of water squeezing out of the sponge 27 after it is fully saturated with water by using a flow guiding component, making it easy to reuse.
