Description

Technical Field

[0001] The utility model relates to the technical field of energy recovery devices, in particular to a 3D pure countercurrent energy recovery device. Background Art

[0002] A low-carbon, pure countercurrent, high-efficiency energy recovery system, constructed from ultra-thin, metal 3D high-efficiency heat exchange elements, undergoes technological integration and optimization innovation. First, the cross-flow collision flow field is transformed into a pure countercurrent friction flow field, achieving full exchange of fresh and exhaust air energy. Second, ultra-low-end differential HERV technology reduces the fresh and exhaust air temperature difference to less than 3°C in summer and less than 5°C in winter, ensuring comfortable indoor temperatures.

[0003] Necessity of Heat (Energy) Recovery Fresh Air Units A. The "Energy Saving Design Standard for Public Buildings" (GB50189-2015) and the "Code for Operation and Management of Ventilation and Air-conditioning Systems" (GB50365-2005) stipulate that exhaust heat recovery devices should be installed when a building has a centralized exhaust system and meets any of the following conditions. The rated heat recovery efficiency of the exhaust heat recovery device should be no less than 60%.

[0004] Air supply volume is greater than or equal to 3000m 3 / h direct current air conditioning system, and the temperature difference between fresh air and exhaust air is greater than or equal to 8℃. The designed fresh air volume is greater than or equal to 4000m 3 / h air conditioning system, and the temperature difference between fresh air and exhaust air is greater than or equal to 8℃. It is equipped with independent fresh air and exhaust systems. Advantages of heat (energy) recovery fresh air unit: (1) Pre-processing of fresh air, reducing air conditioning operating load, saving operating costs. (2) Reducing the maximum load of the air conditioning system, reducing the model of the air conditioning system, saving initial investment. (3) While saving energy, it can increase the indoor fresh air ratio and improve indoor air quality. (4) The reduction of exhaust air temperature in summer reduces the amount of heat discharged to the outside, reduces heat pollution, and alleviates the heat island effect.

[0005] Existing air heat recovery devices within units are categorized by heat exchange type, including plate, plate-fin, rotor, and heat pipe types. Currently, a low-carbon, pure countercurrent, high-efficiency energy recovery device, manufactured using ultra-thin metal 3D high-efficiency heat exchange elements, is undergoing technological integration and optimization innovation. This first transforms the cross-flow collision flow field into a pure countercurrent friction flow field, achieving full exchange of fresh and exhaust air energy.

[0006] The heat exchange core, as its core component, primarily recovers exhaust air heat and cold, achieving energy savings. Its heat exchange efficiency directly impacts the heat recovery unit's temperature exchange efficiency and indoor occupant comfort. Existing energy recovery units utilize an integrated structure, making them difficult to maintain and repair. Furthermore, air leakage during use can lead to poor air delivery and reduced overall efficiency. Low sealing performance also increases costs, making them unsuitable for practical use. No solutions have yet been proposed for these technical issues. Utility Model Content
