When it comes to choosing a heat pump, most people focus on performance, energy efficiency, and appearance. However, with growing expectations for peaceful living spaces, noise levels have become a key decision-making factor for many buyers in recent years.
The good news is that today’s heat pumps are getting quieter than ever before thanks to advanced technologies and thoughtful designs. In this newsletter, we’ll take a closer look at the low-noise operation of heat pumps, exploring what causes their noise, how modern technology is making them quieter, and what you should consider when choosing a model that balances both efficiency and tranquility.
What Causes Noise in Heat Pumps?
Understanding where that noise comes from can help you make smarter choices when selecting a model, planning installation, or troubleshooting sound issues. Here are the main sources of noise in a heat pump:
- Compressor operation: as the core of the system, the compressor generates noise, especially at startup or high speeds. Modern inverter compressors are much quieter, as they can adjust their speed and run much more quietly while meeting heating demands.
- Fan blades and airflow: heat pump units use fans to move air across heat exchangers. As these blades rotate at high speed, they produce airflow noise. The material and design of the fan blade, along with the airflow design can affect the noise level.
- Vibration: Operational vibrations can transfer through the unit and mounting surfaces, amplifying noise. Some heat pump units use anti-vibration mounts and insulation to reduce noise.
What’s the Noise Level of the Heat Pump?
The outdoor units of heat pumps typically produce an average sound pressure level between 40 to 60 dB(A) at a distance of about one meter. However, some advanced or ultra-quiet models have lower noise levels. For example, NEWNTIDE’s quietest model can achieve an incredible noise level as low as 31dB(A) at a distance of 1 meter, even quieter than soft whispers. The Hi-master V series heat pump is specially engineered to meet the growing market demands for an HVAC system that ensures both high efficiency and whisper-quiet operation. This heat pump not only maintains the highest A+++ energy efficiency rating but also ensures an impressively low sound pressure level that makes it stand out among heat pumps on the market.
How Do We Reduce the Noise level of Heat pump?
To achieve ultra-quiet operation, the Hi-Master V Series heat pump incorporates multiple advanced noise-reduction technologies. It adopts the Mitsubishi inverter compressor, which minimizes noise directly at the source by dynamically adjusting its speed to match demand. The unit is also equipped with compressor sound insulation, an aerodynamic fan blade design to reduce airflow noise, an anti-vibration chassis combined with high-quality sound-absorbing materials and so on. Together, these features ensure whisper-quiet performance without compromising efficiency or reliability.
Tips for Reducing the Noise Level of Your Heat Pumps
Model Selection: Choose a heat pump with a variable-speed inverter compressor, fan technology, and acoustic insulation. It is advisable to choose a heat pump with silent mode, which allows you to switch to silent mode to ensure a peaceful living space during evenings, nighttime, or other noise-sensitive periods.
Proper Installation: Avoid installing the outdoor unit directly in front of windows, as well as near bedrooms and echo-prone areas. Proper mounting with anti-vibration measures can also reduce noise transmission.
Regular maintenance:Regular cleaning and upkeep can keep noise at bay. Remove debris from fan blades, coils, and surrounding areas. Check and secure screws, panels, and mounting brackets to eliminate rattling. https://youtu.be/hmKF34MyBgQ
As modern homes and living spaces prioritize both energy efficiency and a peaceful environment, the noise levels of heat pumps have become an important factor for homeowners and businesses to consider when choosing a heat pump, and heat pumps with low noise are gaining more traction in the market.
