Because the heat exchanger 30 and the exhaust fan 2 which are subjected to protection treatment increase the corresponding capacity, the operation efficiency and the output quantity of the air source heat pump 3 are ensured, and finally the air is exhausted into the atmosphere by the exhaust barrel 1 at a certain height or a certain speed, so that the emission requirement specified in the regulation is met.
The utility model discloses a straight-flow air conditioner contains harmful medium and airs exhaust low-grade thermal increase system device has following characteristics:
1. because the volume of airing exhaust of through-flow air conditioner does not match with the air volume of air source heat pump 3, the volume of airing exhaust of through-flow air conditioner is little than the air volume of air source heat pump 3, perhaps the through-flow air conditioner volume of airing exhaust changes, if the volume of airing exhaust in order to guarantee through-flow air conditioner is whole to be siphoned away and not disturbed by gust often adopt the tuber pipe hard joint, not only can not satisfy the volume of airing exhaust of air source heat pump 3, influence air source heat pump 3's efficiency on the contrary. Therefore, the utility model discloses set up the decoupling type air inlet unit between the air intake of air source heat pump 3 and the house steward of airing exhaust of through-flow air conditioner, make the air intake of air source heat pump 3 and the house steward of airing exhaust of through-flow air conditioner between be non-pipeline hard connection, and set up windshield 4 at the air outlet of decoupling type air inlet unit, not only guarantee that the air exhaust of through-flow air conditioner is not escaped outward, and do not receive the interference of outer gust wind, can also satisfy the air volume that air source heat pump 3 normally operates required with minimum resistance through atmospheric air make-up, can dilute the harmful substance in the air exhaust of through-flow air conditioner;
2. the exhaust air of the straight-flow air conditioner contains corrosive substances such as ammonia, formaldehyde, acid and alkali, and the like, so that the components of the exhaust air flowing through the air source heat pump 3, such as a heat exchanger, an exhaust fan, structural components and the like, can be corroded, and the exhaust air is usually absorbed or neutralized by spraying water, acid, alkali and other liquids, and thus, the heat recovery efficiency can be reduced. The utility model discloses do corresponding protection to the heat exchange tube 33 and the fin 32 of heat exchanger 30 to the characteristic of harmful substance in airing exhaust and handle to corresponding optimization heat exchanger 30's structure, in order to compensate the heat transfer volume of handling the decay because of the protection. The utility model discloses the position that exposes to heat exchanger 30 has carried out the protection and has handled, and the surface of heat exchange tube 33 and the surface of fin 32 adopt the electrophoresis to handle formation anticorrosive coating promptly. Because the electrophoretic coating is flexible, the cationic epoxy polymer is uniformly distributed on the surface of the metal, and no bridging phenomenon which can occur in the spraying treatment exists between the fins or the windows. The electrophoresis process ensures that a dry film-shaped anticorrosive layer with the thickness of 20-30 mu m is formed on the outer surface of the heat exchanger 30. The electrophoresis meets the ASTM B3359-97 standard and reaches 4B-5B adhesion grade; corrosion resistance can be tested by ASTM G85a2 salt fog for not less than 2400 hours; the thermal attenuation performance is less than 2%. Since the electrophoresis treatment is performed in a whole immersion manner, the end plate 31 of the heat exchanger 30 is also subjected to the whole electrophoresis treatment, and has the protection capability of the same specification (see fig. 6a, 6b and 6 c).
In addition, considering that the heat exchanger 30 can attenuate the heat exchange amount after the electrophoresis treatment, in order to meet the requirement that the overall performance of the synergistic system device is not reduced, the structure of the heat exchanger 30 is optimized as follows: 1) the conventional corrugated fin is changed into a corrugated windowing type fin structure; 2) the heat exchange copper pipe of the conventional light pipe structure is changed into the heat exchange copper pipe of the internal thread structure, so that the heat exchange area of the heat exchange pipe is increased.
3. Because the exhaust air of the straight-flow air conditioner contains highly pathogenic microorganisms, although the straight-flow air conditioner is subjected to harmless treatment (such as filtration and sterilization through a high-efficiency filter), the discharge height (higher than a certain height of a roof) or the discharge speed is regulated by laws and regulations, and the height of an exhaust outlet and the outlet air speed of a common air source heat pump cannot meet the discharge requirement. The utility model discloses to the straight-flow air conditioner air exhaust height and export wind speed requirement, increase exhaust mechanism on air source heat pump 3's exhaust hole, increase exhaust barrel 1 on the upper portion of exhaust fan 2 promptly. The height of the exhaust duct 1 is determined by the exhaust height required by legislation. The exhaust barrel 1 is made into a straight barrel type or a conical type according to requirements. The size of the opening of the conical exhaust duct 1 is determined according to the exhaust speed required by laws and regulations. After the exhaust duct 1 is added, a mesh cover on the exhaust fan 2 can be cancelled, and a low-density mesh fan cover (the mesh aperture is 20mm) is added at the top of the exhaust duct 1, even a plastic mesh rope with a similar shape is adopted for replacement, so that the integral wind resistance is reduced; meanwhile, the diameter of the exhaust barrel 1 is larger, so that the pressure drop generated by the exhaust barrel 1 with the height of 0.5-1.5 m is very small, and extra pressure loss is hardly generated, so that the performance of the whole machine is hardly influenced.
4. Because the heat exchange quantity of the heat exchanger of the common air source heat pump and the air quantity of the exhaust fan are matched with the air pressure and the air source heat pump, the operation efficiency of the air source heat pump can be influenced by the change or performance reduction of any one part, and the cold and hot water quantity and the water temperature required by the direct-current air conditioner can not be ensured. The utility model discloses not only increase exhaust barrel 1 on air source heat pump 3's the hole of airing exhaust, still adopt the exhaust fan 2 of big wind volume high excess pressure, overcome the problem of the increase of the amount of wind resistance that leads to flowing through heat exchanger 30 because of heat exchanger 30's structure or part change.
The above embodiments are provided only for the purpose of illustration, not for the limitation of the present invention, and those skilled in the relevant art can make various changes or modifications without departing from the spirit and scope of the present invention, therefore, all equivalent technical solutions should also belong to the scope of the present invention, and should be defined by the claims.
