Today's demolition is Hualing N8HA1 new level 1 horse, this air conditioner before everyone cares most about is the electronic expansion valve, because Jingdong customer service has been saying no, whether it is the previous netizens sent me the dismantling map, or this time I dismantled it myself, are confirmed to be there.
Date of manufacture: July 2020
Model: KFR-26GW/N8HA1
Indoor model: KFR-26G/N8HA1
Outdoor model: KFR-26W/BP3N8-B01(HL)

Hualing N8HA1 1 horsepower external machine parameters
Refrigerant: R32/720g
External machine mass: 27kg
Hualing 1 horsepower external machine size, 807 wide (without valve) × 555 high× 328 deep. Midea and Hualing, the new class of 1 horse and 1.5 horse, are currently in this size.
Hualing N8HA1 1 horse 1 row condenser, a total of 24 pipes, the total length of about 21 meters (Hualing N8HA1 1.5 horse 1.6 row pipe is 35 meters)
Hualing N8HA1 1 horsepower external fan, using Midea's own 34w Welling DC motor, 10 pairs of magnetic poles, and the new level of 1.5 horses the same.
Hualing N8HA1 1 horse fan size, 434× 144, this and 1.5 horsepower is the same
Hualing N8HA1 1 hp compressor
Hualing N8HA1 compressor parameters, in the direction of the inside, the photo can not be taken, I used the mirror reflection, saw the use of Meizhi "KSK103D33UEZ3" compressor, which is the old first-class 1.5-horse compressor used in the United States, the exhaust capacity of 10.3cc, the rated cooling capacity of 3255w, the rated refrigeration power of 826w, the energy efficiency ratio of 3.94 (test conditions: SEER60).
In general, 1.5 hp inverter air conditioner, more use of rated cooling capacity between 3000 ~ 3500w compressor, 1.5 hp air conditioning rated cooling capacity is 3500w, so when running in the rated refrigeration power, the compressor is actually in the overclocking state.

<h1 class="pgc-h-arrow-right" data-track="18" > The situation inside the Hualing N8HA1</h1>
The same as the 1.5-horsepower, the through-flow fan of the Hualing N8HA1 internal machine uses a 13w DC motor with a 90.4×657mm caliber wind wheel.
<h1 class="pgc-h-arrow-right" data-track="20" >1 horse, 1.5 horse Hualing N8HA1 comparison</h1>
The 1-horse Hualing N8HA1, and the 1.5-horse are very similar, the difference is
compressor
1 hp: Mash 3.94 energy efficiency
1.5 hp: Medea 4.05 energy efficiency
Heat exchange capacity (1 hp is half of 1.5 hp)
1 hp: single row condenser + 34w fan motor + R32 refrigerant 840 g
1.5 hp: 1.6 row condenser + 56w fan motor + R32 refrigerant 720 g
Why does the 1-horse Hualing N8HA1 use a 1.5-horse air conditioner? Because 90% of the power consumption of air conditioners depends on the compressor, the inverter air conditioning compressors are more energy efficient at 20 to 60Hz, of which the energy efficiency is the highest at 30-35Hz. 1 Pi Hualing N8HA1 chooses a large compressor and runs with a cooling capacity of 25% to 50%, so that the energy efficiency level of the air conditioner is also good.
I also inquired about Hualing N8HE1, and the old first-class cool star 1 horse and other models, and found that in the Midea and Hualing brands, 1 horse air conditioner uses a 1.5 horse compressor, which is already a routine operation, and other brands are also likely to be like this.
If the industry generally puts a 1.5-horse compressor on a 1-horse air conditioner for low-frequency operation, then the textbook method of selecting air conditioning by area and cold volume seems outdated.
The question is, after buying air conditioners in small rooms, should I buy 1 horse or 1.5 horse? Wait until I take the time to study more models to confirm.
