2.3.3 Low Temperature Component

When the outdoor temperature is below the operating temperature lower limit
specified 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.

The outdoor unit is equipped with a high-efficiency variable-frequency drive
axial fan to implement large air flow, low noise, and high efficiency.
The variable frequency drive ensures stable running 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.
When the outdoor condensing pressure is lower than the designed opening
pressure of the condensing pressure regulator valve, the regulator valve closes
and the differential pressure valve opens. The refrigerant at the compressor
outlet is bypassed to the liquid storage unit of the low temperature
component through the differential pressure valve, ensuring that the
condensing pressure stays within a safe and reliable operating range.
When the condensing pressure is higher than the designed opening pressure
of the condensing pressure regulator valve, the regulator valve opens and the
differential pressure valve closes. The refrigerant at the compressor outlet
