In Row Precision Air Cooling Systems
In-row cooling technology is a type of air conditioning system commonly used in data centers in which the cooling unit is placed between the server cabinets in a row for offering cool air to the server equipment more effectively. In Row air cooling system are used in data centers to cool server IT racks and placed in between for precession air cooling system. These are energy efficient smart senor-based air conditioner which maintains cooling temperature in the data center locations:

3. Increased energy efficiency
4. More space
5. More flexibility
Refrigerant Cooling:
Chilled Water Cooling:
Refrigerant-based cooling is another method utilized in in-row cooling systems to remove heat generated by the data center equipment. Refrigerant, a substance with high heat-absorbing properties, undergoes a cycle of compression and expansion to facilitate the cooling process.
Chilled water cooling is a common method employed in in-row cooling systems to efficiently dissipate heat from the data center. In this method, a closed-loop system circulates chilled water through a coil or heat exchanger within the in-row cooling unit. The chilled water absorbs the heat from the air, which is then transferred away from the data center.
Features
In-Row Cooling:
The in-row cooling unit draws warm exhaust air directly from the hot aisle, cools it and distributes it to the cold aisle. This ensures that inlet temperatures are steady for precise operation. Coupling the air conditioning with the heat source produces an efficient direct return air path; this is called “close coupled cooling,” which also lowers the fan energy required. In-row cooling also prevents the mixing of hot and cold air, thus increasing efficiency.
DC Inverter Compressors:
The incorporation of DC inverter compressors in the refrigerant-based cooling units enhances energy efficiency by allowing variable speed control. The DC inverter technology enables the compressor to adjust its speed based on the cooling demand, optimizing energy consumption and ensuring precise temperature control for the IT racks.
DC Driven EC Fans:
DC-driven fans play a crucial role in augmenting the overall energy efficiency of the cooling system. With Electrically Commutated (EC) fans, the integration of DC technology facilitates intelligent speed control. These fans operate with minimal noise, even at low rotational speeds, providing a quieter and more comfortable environment for the data center.
Electronic Expansion Values:
Electronic expansion valves further contribute to the efficiency of the refrigerant-based cooling system. These valves enable accurate regulation of the refrigerant flow, responding dynamically to changing thermal loads. The result is improved system performance, energy savings, and enhanced reliability in maintaining the desired operating conditions within the data center.
