AI Technical Summary
Existing heat pump units suffer from significant compressor noise, and using large-displacement compressors to reduce noise is costly.
The structure employs vibration dampers and noise reduction cylinders to reduce compressor vibration transmission and absorb noise, thereby reducing noise propagation and preventing high-frequency vibration from damaging the pipeline.
While reducing noise, it also reduces the damage to pipelines caused by compressor vibration, extends service life, and lowers costs, eliminating the need for large-displacement compressors.
