AI Technical Summary
Existing air source heat pumps have noise problems due to mechanical vibration and power regulation during operation, especially at night and when operating at high power. Furthermore, the shock absorbers have poor damping effect due to metal fatigue and material aging.
The system employs a switching mechanism that alternates between spring damper one and spring damper two. Combined with the top support assembly and the switching assembly, the system is controlled by stepper motors and servo motors to achieve position switching and precise positioning of the dampers, thereby avoiding resonance and ensuring that the dampers perform optimally under different working conditions.
It effectively reduces the noise of air source heat pumps at night and during high-power operation, extends the service life of shock absorbers, improves the damping effect, and avoids resonance problems caused by frequency mismatch of a single shock absorber.
