Basic Knowledge of
Huawei Precision Air Conditioner Intro
Overview of Precision Air Conditioner
Precision Air Conditioner Function
Why Use Air Conditioner
Unable to maintain cte Temp > Greatly reduce service life of electronic components
Partial Superheat > Equipment suddently shutdown
Too high Humidity > generate condensate water
Too low humidity > generate damaging static electricity
not clean enough > equipment Damage , communication data error
Why Use Precision Air Conditioner
High energy efficiency > Cofficient of Performance COP>3.0
High sensible heat ratio > 0.9
High air Volume
Cooling Throughout the year
High precision control over temperature and humidity
long service life > 10 years
Apps Scenarios
Modular data center
container data center
Medium or large data center

Chilled-water Precision Air Conditioner
Main Components
Common auxiliary components
Power supply unit - Provide stable power supply to the fan;
Condensate water pump - Drain
condensate water from the system;
Float - Used to control condensate water
level.
Main components of refrigerating system
Two way valve - The water flow into the air conditioner is adjusted continuously according to
the change of the thermal load, and the temperature is accurately controlled;
Fan - Accelerating the air flow and improving the heat transfer capability of the heat exchanger;
Surface air cooler - A component that controls the indoor temperature and humidity by
exchanging heat between chilled water and indoor air.
