I.Core answer
The sound insulation effect of Huaquanfang soundproof generator set (quiet type) is excellent. The operating noise at a distance of 7 meters can be as low as below 75 desibel, significantly lower than the 95-110 decibels of traditional open-frame generator sets.
| Comparison item | Huaquan silent type unit | Traditional open-rack unit |
| Noise at 7 meter | ≤75 decibels | 85-100 desibel |
| Noise at 1 meter | ≤75-85 decibels (depending on power) | 95-110 desibel |
| Human perception | Equivalent to the normal conversation volume of two people | Equivalent to the sound of a chainsaw or firecrackers |
| Applicable Environment | Hospital, kawasan perumahan, pusat data, hotel | tapak pembinaan, wilderness areas, and factories far away from crowds |
Huaquan Power tips: Huaquan Penjana Senyap sets adopt a fully enclosed noise reduction enclosure filled with multiple layers of sound-absorbing materials, digabungkan dengan reka bentuk muffler yang cekap. Sama ada operasi waktu malam atau penggunaan di kawasan perumahan, ia memastikan operasi yang tenang dan bebas kebimbangan.
II.Perbandingan desibel untuk kesan bisu
Untuk memahami secara intuitif apa 75 desibel ialah, berikut ialah jadual perbandingan bunyi biasa:
| Sumber bunyi | Nilai desibel | Berbanding dengan unit senyap Huaquan |
| perpustakaan lewat malam | 30dB | lebih senyap |
| Pejabat sunyi | 40-50dB | lebih senyap |
| Unit senyap Huaquan (di 7 meter) | ≤75dB | — |
| Dua orang itu berbual biasa | 60-75dB | Tahap yang sama |
| unit luar penghawa dingin | 50-60dB | Rendah sedikit daripada unit senyap |
| Jalan yang sibuk | 70-85dB | Setaraf dengan enjin pesawat senyap |
| Unit bingkai terbuka tradisional (di 7 meter) | 85-100dB | 10-25dB lebih tinggi daripada unit senyap |
| Bunyi gergaji elektrik/bunyi mercun | 100-110dB | Tahap unit tradisional |
Untuk setiap 10 peningkatan dB, jumlah yang dirasakan oleh telinga manusia lebih kurang dua kali ganda. Unit senyap Huaquan ialah 20-35 dB lebih rendah daripada unit tradisional, yang bermaksud kekerasan yang dirasakan adalah sahaja 1/4 kepada 1/8 daripada unit tradisional.
III. Jaminan Teknikal untuk Kesan Senyap
Set penjana senyap Huaquan mencapai operasi hingar ultra-rendah melalui pelbagai reka bentuk pengurangan hingar:
- Struktur pengurangan hingar tidak sepadan impedans berbilang lapisan
Kotak kalis bunyi Huaquan diguna pakai struktur pengurangan hingar galangan halangan berbilang lapisan. Permukaan dalam kotak direka bentuk dengan undulasi cekung dan cembung, yang menjadikan jarak antara enjin pembakaran dalaman dan badan kotak tidak tetap, membentuk beberapa lapisan halangan. Ini menyukarkan bunyi bising untuk membentuk laluan balik biasa.

VII. Common Issues
S1: How quiet is 75 desibel?
A: 75 decibels is approximately equivalent to the volume of normal face-to-face communication between two people. This means:
- It will not affect normal conversation from a distance of 7 meter
- Using it at night will not disturb residents’ rest
- The hospital environment is safe for use
S2: Can the silent air conditioning unit be used outdoors in rainy weather?
A: ya, ia boleh. The Huaquan soundproof box is made of steel plates, with a rust-proof paint coating on the surface. It features noise reduction and waterproof capabilities. The box is fully enclosed, with good sealing, providing protection against rain, salji, and dust.
S3: Does a silent air conditioning unit require an additional machine room?
A: No need. Huaquan’s silent unit adopts a fully enclosed noise reduction enclosure with high protection level, which can be directly placed on a flat outdoor ground without the need to build a machine room, greatly saving installation costs and time.
Q4: Are the noises produced by silent air conditioning units of different power levels the same?
A: There are slight differences. Secara umumnya, higher power tends to result in slightly louder noise
- 30-100kW：65-72dB
- 100-300kW：70-75dB
- 300-600kW：72-78dB
Namun begitu, all Huaquan silent units are controlled to be around 75dB (at a distance of 7 meter), which is much lower than traditional units.
Q5: Will the noise reduction effect of the silent unit degrade over time?
A: With proper use and maintenance, the sound insulation effect will not significantly deteriorate. The Huaquan sound insulation box body is made of high-flame-retardant sound insulation cotton and galvanized sheet metal partitions, ensuring good durability. It is recommended to regularly check the status of the box body’s sealing strips and sound absorption materials, and replace them promptly if damaged.
Q6: Can silent air conditioning units be used in data centers?
A: ya, the Huaquan 500kW silent unit has been widely used in data centers. Equipped with a self-starting control system, it achieves unattended operation and ensures 24-hour uninterrupted power supply. The noise level at a distance of 7 meters is ≤75dB, meeting the requirements of data centers for the operating environment.
