Compressors

The characteristics and advantages of a twin-rotor compressor are as follows:

1. **Fewer Components and Simple Structure**: The design has fewer parts, resulting in fewer wear-prone components, which enhances reliability during operation.

2. **Absence of Intake Valve Plates**: This design eliminates intake valve plates, leading to a smaller clearance volume.

3. **Higher Gas Transmission Coefficient**: The compressor offers a higher gas transmission coefficient, which necessitates high precision in manufacturing.

4. **High Low-Frequency Energy Efficiency Ratio**: The compressor exhibits a high energy efficiency ratio at low frequencies

Refrigerant 454b

Environmental Impact of R-454BNew systems using R-454B refrigerant are more energy efficient, reducing greenhouse gas (GHG) emissions from the use of electricity, and the refrigerant itself has lower GWP.R-454B has no ozone depletion potential (ODP) and has low toxicity.R-454B GWP is more than 75% lower than its most recent predecessor, R-410A, and surpasses the EPA requirements for low-GWP refrigerant (<700 GWP).It’s more energy efficient.Although you may have never heard of it until today, the R-454B refrigerant has already demonstrated exceptional performance during Trane’s field trials in the U.S. Department of Energy’s (DOE) Cold Climate Heat Pump Challenge.
