[0002] Heating, ventilation, and air conditioning (HVAC) is a collective term for three functions, derived from the abbreviation of its core functions: Heating: providing heat to buildings in winter to maintain a comfortable indoor temperature; Ventilation: introducing treated fresh outdoor air into the room and expelling stale indoor air to ensure indoor air quality and health; Air Conditioning: a broader concept that is not just "cooling." It includes: Cooling: removing heat from the room in summer to lower the indoor temperature; Dehumidification / Humidification: regulating indoor humidity to maintain it within a comfortable range; Filtration: removing pollutants such as dust, pollen, and bacteria from the air; Airflow Organization: ensuring even distribution of indoor air and avoiding dead zones and strong drafts. The core objective is to create a comfortable, healthy, and safe indoor environment for people's lives, work, and production, while also considering energy conservation and environmental protection.

[0003] If existing HVAC waste heat recovery devices can be maintained and cleaned without shutting down the system, the continuity and comfort of the indoor environment can be guaranteed. This also avoids huge downtime costs and economic losses, greatly improves the safety and convenience of maintenance operations, and ensures that waste heat can be better recovered during maintenance and cleaning even without shutting down the system. This avoids the waste heat caused by the waste heat recovery device being unusable during maintenance and cleaning.

[0004] In view of this, this paper studies and improves the existing problems, and provides a waste heat recovery device for HVAC systems. The aim is to solve the problems and improve the practical value through this technology. Utility Model Content

[0023] Please see Figures 1 to 4 This utility model provides a specific technical implementation scheme for a waste heat recovery device for heating, ventilation, and air conditioning systems:

[0024] A waste heat recovery device for heating, ventilation, and air conditioning systems includes: a first housing 1, a second housing 2, a drawer plate 3, a filter screen 4, a partition plate 5, a sealing gasket 6, a conduit 7, a diversion pipe 8, a control valve 9, an air inlet pipe 10, an air outlet pipe 11, a water outlet pipe 12, a heat exchange pipe 13, a water inlet pipe 14, and heat exchange fins 15. The first housing 1 has a cylindrical structure, and the top of it is fixedly connected to the second housing 2. The top of the inner wall of the first housing 1 is perforated by a conduit 7 that communicates with the bottom of the inner wall of the second housing 2. The inner wall of the second housing 2 is fixedly connected to the partition plate 5, and both sides of the partition plate 5 are... The second housing 2 is fitted with drawer panels 3, and the outer walls of both drawer panels 3 are fitted with the inner walls of the second housing 2. Filter screens 4 are fixedly connected to the inner walls of both drawer panels 3. A diversion pipe 8 is connected to the top of the second housing 2. Two control valves 9 are connected to the inner walls of the diversion pipe 8. An air inlet pipe 10 is connected to the top of the diversion pipe 8. The mesh size of the filter screen 4 is not limited, as long as it meets the usage requirements. The partition 5 can divide the interior of the second housing 2 into two purification spaces, and the airflow direction can be changed by controlling the valves 9 to transmit the airflow to different purification spaces.

[0025] Sealing gaskets 6 are fixedly connected to the outer walls of the two drawer panels 3 and the second box 2. Sealing gaskets 6 can improve the sealing performance between the drawer panels 3 and the second box 2, and can also increase the connection friction to prevent the drawer panels 3 from accidentally detaching from the inner wall of the second box 2. The material of sealing gaskets 6 can be silicone rubber composite gaskets. There are no restrictions on the specific material. It can be selected according to the actual use.

[0026] A handle is fixedly connected to one side of the outer wall of each of the two drawer panels 3, and the guide tube 7 has an English "Y" shaped structure; the handle design allows the staff to more conveniently pull the drawer panel 3 out of the inner wall of the second box 2.

[0027] A water inlet pipe 14 is connected to the lower side of one side of the first housing 1, and a water outlet pipe 12 is connected to the upper side of one side of the first housing 1. External water can enter the interior of the first housing 1 through the water inlet pipe 14 and then be discharged from the interior of the first housing 1 through the water outlet pipe 12 so as to recover waste heat through heat conduction.

[0028] The end of the conduit 7 is connected to a heat exchange tube 13, and a heat exchange plate 15 is fixedly connected to the inner wall of the heat exchange tube 13. The bottom of the heat exchange tube 13 is connected to an air outlet pipe 11, and the outer wall of the air outlet pipe 11 penetrates the lower side of one side of the first box 1. Hot air can heat the water inside the first box 1 through the heat exchange tube 13 and the heat exchange plate 15, thereby realizing waste heat recovery.

[0029] Specifically, it should be noted that during use, staff need to regularly maintain and clean different areas of the second box 2. The specific cleaning cycle can be determined according to the actual usage situation to meet the actual usage needs. During use, in order to ensure the stability of the drawer panel 3, a lock that cooperates with the second box 2 and the drawer panel 3 can be installed. The lock can be used to fix the second box 2 and the drawer panel 3. The specific structure, operation steps and usage of the lock are not limited, and these are all existing technologies known to those skilled in the art. Therefore, this case will not elaborate on them. In addition, this case should be provided with an external cooperating mechanism that cooperates with the water inlet pipe 14 and the water outlet pipe 12 so that water can be transported to the interior of the first box 1 through the water inlet pipe 14. Then, the heated water is discharged from the interior of the first box 1 through the water outlet pipe 12 for subsequent use. The specific external structure is not limited and can be determined according to the actual usage situation. Those skilled in the art should interpret it broadly.

[0030] Specific implementation steps:

[0031] During use, the operator delivers hot air to the interior of the second chamber 2 through the intake pipe 10 and the diverter pipe 8. It should be noted that one of the two control valves 9 is in the open state and the other is in the closed state. The airflow is then filtered through the filter screen 4 and then enters the interior of the heat exchange tube 13 through the conduit 7. The heat exchange tube 13 and the heat exchange plate 15 then heat the water at the bottom of the first chamber 1, thereby realizing waste heat recovery. The water is then discharged from the interior of the first chamber 1 through the exhaust pipe 11. At the same time, external water enters the interior of the first chamber 1 through the water inlet pipe 14 and is discharged through the water outlet pipe 12. When cleaning, the operating status of the two control valves 9 is readjusted. Then the drawer plate 3 can be removed for maintenance and cleaning.

[0032] In summary, this HVAC waste heat recovery device, through the arrangement of a first housing, a second housing, partitions, drawer panels, filters, diversion pipes, control valves, and conduits, can perform zoned dust filtration. Furthermore, during single-zone cleaning, airflow is transferred to another area, ensuring that maintenance and cleaning do not require shutdown. This guarantees the continuity and comfort of the indoor environment, avoids significant downtime costs and economic losses, and greatly improves the safety and convenience of maintenance operations. Even when the HVAC system is not shut down, waste heat can still be better recovered during maintenance and cleaning, preventing heat waste caused by the device being unusable during maintenance and cleaning. This invention, through improvements to the HVAC waste heat recovery device, has the advantages of improving the efficiency and quality of waste heat recovery and eliminating the need for HVAC shutdown, thus effectively solving the problems and shortcomings of existing devices.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
