Direct Conclusion
The device outputs a frequency sweep from 0 to 60 kHz, covering the frequency range for various circulating water qualities. Operation remains stable under low winter temperatures and short-term fluctuations during makeup water addition; however, significant changes in makeup water hardness or alkalinity require verification through monitoring.
Judgment Criteria
- 01
Low temperatures primarily affect the scaling rate but do not impact power operation or coil performance.
- 02
Log changes in hardness, alkalinity, and turbidity during makeup water switching or sudden water quality shifts; monitor the heat exchanger terminal temperature difference.
- 03
For operating conditions with significant fluctuations, the observation period shall be specified separately in the acceptance agreement.
Applicable Conditions
Outdoor installation requires waterproofing, freeze protection, and sun protection based on site conditions.
