Description

Technical Field

[0001] This utility model relates to the field of heat exchange technology, and in particular to a heat exchange air conditioning unit system. Background Technology

[0002] With rapid economic development, total energy consumption in my country and worldwide has increased year by year. The massive consumption of fossil fuels has led to serious environmental pollution problems, and energy shortages and environmental pollution have become major global issues. Therefore, the utilization and vigorous development of clean and renewable energy have become a development trend and an important way to achieve energy conservation and environmental protection. Heat pump technology, especially wastewater source heat pump technology that uses urban sewage heat as a low-grade heat source for cooling, has become one of the effective ways to achieve energy conservation and environmental protection, and is increasingly attracting attention from countries around the world.

[0003] Chinese Patent Publication No. CN205957765U discloses a combined urban sewage and urban ground source heat exchange system, including heat exchange pipes, a heating system, a heat pump, sewage suppliers, heat users, sewage pipes, and a sewage tank. The heat exchange pipes include a sewage delivery pipe and a heat exchange pipe wound around the outer edge of the sewage delivery pipe. The heat exchange pipes contain clean water. Sewage with a temperature of 10-20°C provided by the sewage suppliers is collected through the sewage delivery pipe in the exchange pipes and flows to the sewage tank. The clean water is connected to the heat pump installed in the heating system through the heat exchange pipes. The heat pump delivers the clean water to the heating system for heating to 60-90°C. The 60-90°C clean water is then delivered to the heat users through pipes.

[0004] It is evident that existing technologies have the following problems when providing heating: the lack of fixed insulation devices in sewage pipes leads to low heat collection efficiency. Utility Model Content

[0005] Therefore, this utility model provides a heat exchange air conditioning unit system to overcome the problem of low heat collection efficiency caused by the lack of heat insulation fixing devices for sewage pipes in the prior art.

[0006] To achieve the above objectives, this utility model provides a heat exchange air conditioning unit system, comprising:

[0007] A heat collection chamber is connected to a sewage treatment pipeline via a ring-shaped support frame. The heat collection chamber is equipped with an air inlet and an air outlet, and an exhaust fan is fixedly installed inside the air outlet.

[0008] The heat exchanger assembly, which is installed inside the air conditioning unit, consists of a first heat exchanger and a second heat exchanger.

[0009] The return pipe has its inlet connected to the outlet of the first heat exchanger and its outlet connected to the inlet of the second heat exchanger.

[0010] The circulating pipeline consists of a circulating inlet pipe and a circulating outlet pipe. The circulating inlet pipe is connected to the inlet of the first heat exchanger, and the circulating outlet pipe is connected to the outlet of the second heat exchanger.

[0011] Furthermore, the annular support frame includes a fixed ring and a support frame. The support frame is composed of longitudinal beams and transverse beams. The longitudinal beams and transverse beams are symmetrical on both sides of the central axis of the sewage treatment pipeline, and the straight lines they are on are perpendicular to each other. A diagonal tie rod for fixing the transverse beam is connected between the transverse beam and the fixed ring.

[0012] Furthermore, the longitudinal beam includes a first longitudinal beam and a second longitudinal beam;

[0013] The first longitudinal beam and the second longitudinal beam are connected by a threaded hole in a fixing ring.

[0014] Furthermore, the fixing ring is composed of two half-rings, and the half-rings are of the same size;

[0015] Each half ring has threaded holes at both ends.

[0016] Furthermore, the heat collection chamber includes an anti-corrosion layer, a heat insulation layer, and a heat insulation layer, wherein the anti-corrosion layer is the inner layer, the heat insulation layer is the outer layer, and the heat insulation layer is located between the heat insulation layer and the anti-corrosion layer.

[0017] Furthermore, the diameter of the exhaust fan is slightly smaller than the diameter of the air outlet.

[0018] Furthermore, a rotating hinge and a locking device are respectively provided on both sides of the heat collection chamber;

[0019] The rotating hinge and the locking device are centrally symmetrical.

[0020] Furthermore, the locking device includes a locking ring, a bolt, and a nut.

[0024] Compared with existing technologies, the advantages of this invention lie in its ability to collect heat from sewage treatment pipelines through a heat collection chamber, thereby improving energy reuse efficiency, reducing external energy demand, and meeting energy conservation and emission reduction requirements. The design of the ring-shaped support frame, particularly the symmetrical arrangement of the longitudinal and transverse beams and the use of diagonal tie rods, enhances the stability and load-bearing capacity of the entire system. The fixing ring consists of two semi-rings, facilitating installation and disassembly, while the threaded connection between the longitudinal beams and the fixing ring simplifies the assembly process. The anti-corrosion layer, insulation layer, and heat insulation layer design of the heat collection chamber effectively prevent corrosion, reduce heat loss, and improve heat exchange efficiency. The diameter of the exhaust fan is slightly smaller than the outlet diameter, ensuring smooth exhaust and reducing pressure loss. Simultaneously, the design of the rotating hinge and locking device ensures the safe sealing of the heat collection chamber. The locking device includes a locking ring, bolts, and nuts, making the opening and closing of the heat collection chamber simple. A welding connection is provided in the middle of the semi-rings, and its distance from the central axis of the sewage treatment pipeline is equidistant, ensuring uniform stress on the support frame and extending its service life. By utilizing the heat in the sewage treatment pipelines, energy consumption is reduced, and an additional heat management solution for sewage treatment is provided, which is beneficial to environmental protection. In summary, this heat exchange air conditioning unit system has significant advantages in terms of improved energy efficiency, structural design, installation and maintenance, corrosion resistance and insulation, safety and reliability, ease of operation, and environmental friendliness.

[0043] Specifically, the longitudinal beam includes a first longitudinal beam 3021 and a second longitudinal beam 3022;

[0044] The first longitudinal beam and the second longitudinal beam are connected by a fixed ring threaded hole 3011.

[0046] Each half ring has threaded holes at both ends.

[0050] Specifically, the diameter of the exhaust fan is slightly smaller than the diameter of the air outlet.
