Features
● The fan is designed to achieve air volume, low noise, and high
eciency.
● The fan motor has excellent waterproof performance and meet IPx5
requirements.
● The outdoor fan speed is adjustable from 10% to 100%. The minimum
operating frequency of the fan is less than or equal to 5 Hz, enabling the
outdoor unit to run stably at low loads.
● Using the galvanized sheet and surface phosphatization + powder coating
techniques, the outdoor unit adapts to harsh environments with its sound
rigidity and anticorrosion performance.
● Pressure preservation is performed on the condenser before delivery, and the
pipe ports are properly sealed to prevent foreign matter from entry.
2.3.3 Low Temperature Component
Working Principle
When the outdoor temperature is below the operating temperature lower limit
specied for the product, the condensing pressure of the system for the outdoor
unit condenser with natural cooling may still be below the safe operating pressure
of the compressor. A low temperature component is required to address this issue.
The low temperature component automatically controls the condensing pressure
to ensure that the smart cooling product works safely and reliably at an outdoor
ambient temperature of –40°C.
