Small Computer Room Precision Cooling Units Data Centre Cooling Equipment
Air-cooled Energy-saving Computer Room Precision Cooling For Small Data Centers And Base Stations
Product Introduction
The SDA.HP unit is a type of air-cooled energy-saving computer room air conditioner designed specifically for small data centers and base stations. The unit is equipped with two cooling systems: a gravity-driven heat pipe cooling system and a compressor cooling system. Based on the actual year-round cooling requirements of data centers, the unit automatically selects the appropriate cooling mode. It fully utilizes natural cooling sources during periods of low outdoor temperatures, significantly reducing the unit's annual energy consumption.

-
Outdoor ambient temperature: 35°C
-
Axial fan, G4 filter configuration
-
The indoor and outdoor units must be connected with special piping for the mechanical cooling and heat pipe cooling systems. The outdoor unit must be higher than the top of the indoor unit.
-
When the outdoor ambient temperature is 5°C, the cooling capacity of the heat pipe alone is 70% of the compressor's rated cooling capacity.
-
When the outdoor ambient temperature is -5°C, the cooling capacity of the heat pipe alone is 100% of the compressor's rated cooling capacity.
-
When the outdoor temperature is 15°C or lower, the heat pipe and compressor operate simultaneously, and the cooling capacity can reach 150% of the rated cooling capacity.
