In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The fresh air haze removing machine shown in fig. 1 and fig. 2 comprises a fresh air channel and an exhaust air channel, wherein a fresh air fan 1 is arranged in the fresh air channel, an exhaust air fan 2 is arranged in the exhaust air channel, fresh air is introduced into the fresh air haze removing machine from a fresh air side due to the requirement of purifying the outside, a total heat exchange core is protected at the same time, the service life of the total heat exchange core is prolonged, a purifying part is usually arranged in a fresh air inlet cavity, a high efficiency physical filter (HEPA) is usually adopted for achieving higher primary filtering efficiency, a purifying part is usually arranged in an exhaust air inlet cavity for protecting the total heat exchange core and prolonging the service life of the total heat exchange core, the purifying part is usually a coarse filter because the indoor air quality is better, the purifying part is a coarse filter, the resistance of the coarse filter is smaller, and the resistance of the HEPA is determined to be larger due to the characteristics of the HEPA, the diameter of the fan blade of the fresh air fan 1 is larger than that of the fan blade of the exhaust fan 2, the fresh air fan 1 with the larger diameter of the fan blade is used for meeting the resistance required to be overcome by the fresh air side, and the exhaust fan 2 with the smaller diameter of the fan blade is used for meeting the exhaust side, so that the problem of energy consumption waste of the exhaust fan 2 caused by the fact that the fresh air fan 1 and the exhaust fan 2 are the same in size in the prior art is solved.
In order to make the air volume, static pressure, power and noise of the whole machine reach relatively ideal balance values, the relationship between the air volume Q1 of the fresh air fan 1 and the air volume Q2 of the exhaust air fan 2 is as follows:

experimental tests comparative data are shown in table 1:
TABLE 1
as can be seen from the test data in table 1:
In the first group of schemes, the fresh air fan and the exhaust fan both use fan blades with the diameter of 255mm, and the air quantity is 254m when the static pressure outside the machine is 100Pa3H; can not satisfy 350m3Design goal of/h. The air quantity is 350m under the condition of the static pressure of 40Pa outside the machine3H; the design target of the external static pressure of 100Pa cannot be met. Therefore, the first group of proposals can not meet the design target of the whole air volume 350m3/h when the external static pressure is 100 Pa.
In the second group of schemes, the fresh air fan uses fan blades with the diameter of 285mm, the exhaust fan uses fan blades with the diameter of 255mm, and the air quantity is 360m3/h when the external static pressure is 100 Pa; the design target of the whole machine air volume of 350m3/h can be met when the external static pressure is 100 Pa. Noise data can also meet design requirements.
In the third group of schemes, the fresh air fan and the exhaust fan both use fan blades with the diameter of 285mm, and the air volume is 502m3/h when the machine external static pressure is 100Pa according to the test result; the air volume of the whole machine is far larger than the design target of 350m3/h, and at the moment, the power of the whole machine is 350w and is larger. The external static pressure is 175Pa when the air volume of the whole machine is 350m 3/h; far greater than the design target of overboard static pressure 100 Pa. Therefore, the third group of schemes are not suitable for the design target of the whole air volume 350m3/h when the external static pressure is 100 Pa.
By combining the analysis, in order to meet the requirements that the air volume of the whole machine meets 350m3/h when the static pressure outside the machine is 100Pa, and the noise meets the design requirement, the power of the whole machine is relatively low, and the fan blades of the whole machine fresh air fan and the exhaust fan are required to be matched and respectively used according to the second group of schemes.
