CSF Refrigerant Precision Air Conditioner
CSF refrigerant precision air conditioner uses natural cooling with three automatic switching modes: compressor, hybrid, or refrigerant-pump cooling. In low outdoor temperatures, its cooling efficiency is multiple times higher than mechanical cooling, significantly lowering computer room PUE.
AEER up by60%
Combining variable frequency control and refrigerant yields a 60% AEER improvement over VFD air-cooled systems
Three modes of operation
Seamless transition between compressor, hybrid, and refrigerant-pump modes to maximize natural cooling.
“0”power wet-membrane humidification, no reheat
Evaporative humidification via water, cooling air while humidifying
Value proposition
High reliabilityFully variable frequency design for precise control
Components like fans, wet membranes, electrical control boxes and filters are all designed to be retractable, enabling 100% front-access maintenance for optimal serviceability
Fully integrated unit design; indoor and outdoor sections connected with threaded pipes - no welding needed
High efficiencyThree-mode cooling leverages natural cooling and reduces compressor power
AEER up 60% with variable frequency control + refrigerant combo
Wet-membrane humidification is more stable and over 99% more energy-efficient versus infrared methods, with no reheat
Intelligent operationsSelf-developed intelligent control system - supports rotation, stacking, anti-conflict management and failover
Standard RS485 interface with multi-level passwords
Network control supports up to 32 units
