Hualing HK1 1.5 hp new class, internal wind wheel, using Welling 13w brushless DC copper wire motor
Hualing HK1 uses Welling 78 series 13w copper wire motor, Welling this series of motors is good, that is, 13w power is small. Midea and Hualing 1.5 horse new first-class hang-up machine, the current internal motor power is 13w.

In general, Hualing HK1 belongs to the "big air outlet" internal machine configuration of the United States, using φ94mm through-flow fans, with double-row 15 groups of 65cm condensers, this configuration is the same as the internal machines of Hualing HE1 and Hualing HC1.
<h1 class="pgc-h-arrow-right" data-track="137" > Hualing HK1 fresh air part</h1>
Open the front panel of Hualing HK1, and on the left are the fresh air outlets and filters.
Inside the red frame is the entire fresh air part, and you will see it when you remove the shell
Hualing HK1 fresh air is an independent air outlet and does not go through the heat exchanger and only one line is connected to the electronic control board, which is also the design scheme of most fresh air conditioners now
Hualing HK1 1.5 hp new grade, fresh air filter and HEPA filter
Hualing HK1 fresh air filter is also relatively simple, HEPA filter is only about one finger thick, quite thin.
Hualing HK1 1.5 hp new class fresh air duct, 2.5 meters long
Hualing HK1 1.5 hp normal fresh air volume is 40m³/h, the maximum fresh air volume after reaming up to 60m³/h, the air inlet of the fresh air duct does not have a primary effect filter.
In general, Hualing HK1's fresh air scheme is relatively simple, it can also be said to be simple, the air volume is not large, the filtering capacity of the filter is not the same, not as good as the mainstream air purifier, nor as good as the wall-mounted fresh air blower. However, Hualing HK1's main competitor, Mijia's fresh air conditioner, is also a similar solution.
My preliminary judgment at present is that in terms of fresh air and air filtration, Hualing and Mijia are both rookies pecking at each other's level, only to pursue product selling points, and have not solved the fresh air needs of consumers (carbon dioxide concentration dropped to within 1000ppm). This conclusion is based on my preliminary judgment based on the Hisense 60m³/h fresh air conditioner that I measured before, and then I looked for an opportunity to measure the effect.
<h1 class="pgc-h-arrow-right" data-track="147" > Hualing HK1 noise cancellation processing</h1>
Hualing HK1's sound attenuation, mainly based on the sound-deadening sponge, can not see a large area of foam for sound suppression and temperature insulation, the estimated performance of the operating noise is general, and Hualing HA1, HE1 is at the same level.

After dismantling the machine, in terms of external configuration, Hualing HK1 uses Meizhi 9864 compressor, with electronic expansion valve, 1.6 rows of condenser, with a total length of about 34.1 meters, with a 34w DC motor. The external machine configuration is the same as Hualing HC1 and Midea's fresh air, and it is not as good as Hualing HE1.
In terms of internal configuration, Hualing HK1 uses a double row of 15 groups of 30 copper tube evaporators, with a 13w Welling DC motor, and a relatively large φ94×650mm wind wheel, with left and right sweeping function, this configuration and Hualing HE1, Hualing HC1, Midea Huanxinfeng is the same.
In general, I think that Hualing HK1 is the beautiful new style vest, the two models have different subtle indicators, but the main components and indicators are the same. The external configuration of Hualing HK1 is general (similar to HA1), the internal configuration is better (the same as HE1), and the fresh air function is chicken ribs.
Buying advice: I think the price of Hualing HK1, in Hualing HA1 + 500 yuan is more reasonable (2600 ~ 2700 yuan), after all, Mijia fresh air conditioning, that is, on the basis of N1A1 added 500 yuan, and this simple fresh air program, the estimated price of 500 yuan is not low.
However, there are also many people who have expressed their need for fresh air conditioning to me. The reason is either that the wall has no place to open a hole for the fresh air, or the room cannot open the window on the street. In the case of last resort, it is believed that "fresh air is better than no fresh air", even if the carbon dioxide concentration cannot be reduced to within 1000ppm, it is good to drop from 2000ppm to 1500ppm, or 1800ppm.
If you are also in this demand, then I think Hualing HK1 is indeed a relatively good model at present, which is definitely better than Mijia Fresh Air.
Supplement: The dismantling of Hualing HK1, I expected to send it at noon on August 14, but the logistics were delayed, and the air conditioner was sent to me a day and a half later than expected. Then when the machine is disassembled, some parts of the internal fresh air are not disassembled, and I do not see the internal machine and wind wheel of the fresh air, I continue to study to see if I can take it apart, and also find an opportunity to test the fresh air effect of this machine.
