2.2.6 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.
Issue 13 (2023-08-20)
Adopted 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.
The water valve is pre-integrated to save onsite installation time.
The water-cooled module can be installed in stack mode to maximize the
installation space and reduce the footprint.
The water-cooled module uses cooling water for heat exchange to improve
the heat exchange efficiency and improve the energy efficiency of the entire
system to 4.0 COP.
