Rechi Compressor: Noise Control and Low-GWP Refrigerant Compatibility

I. Noise Control Technology

For air conditioners, dehumidifiers, and heat pump equipment, operating noise is a key factor affecting user experience.

Rechi's noise control solutions include the following two technologies:

1. Electromagnetic Noise Suppression: Development of a new magnetic flux harmonic model to suppress electromagnetic noise while improving motor operating efficiency.

2. Broadband Noise Decoupling: Application of acoustic engineering technology combined with an all-in-one soundproofing and sound-absorbing module to achieve full-spectrum noise suppression.

II. Low-GWP Refrigerant Compatibility: R32, R454B, and R290

The application of low-GWP refrigerants such as R32, R454B, and R290 imposes higher requirements on compressor structural design and material selection.

Rechi's compatibility solutions are as follows:

1. R32 and R454B: Through structural optimization and advanced simulation technology, the clearance of internal moving parts is adjusted to reduce leakage risk under high-pressure conditions.

2. R290: Development of an all-aluminum compressor with good sealing performance, heat dissipation capability, and safety compliance, which has passed relevant safety certifications.

III. Segment Market Applications

1. Heat Pump Water Heaters and Heat Pump Dryers

Rechi has developed a dedicated compressor for wall-mounted heat pump water heaters. When used in conjunction with a high-efficiency plate heat exchanger, test data shows an energy saving effect of over 60%.

2. Parking Air Conditioners

Rechi has developed a 12V/48V DC inverter compressor specifically for parking air conditioning systems. This compressor features high vibration resistance, low energy consumption, and direct battery power supply, and is primarily targeted at the retrofitting market in North America and Australia.

IV. Summary

Rechi has formed clear technical solutions in the following areas:

1. Low-noise operation through electromagnetic noise suppression and broadband noise decoupling

2. Compatibility with R32, R454B, and R290 refrigerants through structural optimization and material innovation

3. Dedicated product solutions in the heat pump and parking air conditioner segment markets
