Fundamentally, cooling the computer equipment in a data center is about moving heat energy most efficiently. Some data centers use air and some use water, but the OptiCool system uses R134a, a non-toxic, synthetic refrigerant. R134a has superb thermodynamic properties, which make it an ideal medium for moving heat. For a given volume, water can absorb 3,400 times more heat than air. In comparison, R134a can absorb nine times more heat than water making it the lifeblood of OptiCool’s cooling solution
Refrigerant Delivery Network (RDN)
The RDN is composed of refrigerant-grade copper piping, factory-built refrigerant distribution segments, and flexible stainless-steel hose pairs. Self-sealing quick-connect couplers join the AHX cooling units with the supply and return lines. The quick-connect feature allows for modularity, flexibility, and reduced on-site installation times.
Refrigerant Pump Systems (RPS)
The RPS circulates refrigerant to the Active Heat Extractors. The pump includes a chilled-water heat exchanger to remove heat from the refrigerant. When chilled water is not available, we use outdoor condensers to reject heat. Virgin R-134a refrigerant is circulated at low pressure with no compression so no oils are used. Refrigerant temperature is strictly maintained to prevent condensation. There are multiple pump models to support various power input arrangements and outdoor environmental conditions.
Active Heat Extractor (AHX)
The AHX is the cooling unit installed inside the door. Each consists of an evaporator coil and two fan units. The fan draws hot exhaust through the coil, causing the pumped refrigerant to undergo a phase change, thereby removing the heat. Each unit consists of two variable-speed fans for efficiency and redundancy. Cooling units can be removed or installed without disruption to service.
AHXs are available in 10kW and 20kW heat removal configurations.
Cool Door System (CDS)
The CDS offers a unique modular mounting system which can accommodate up to 3 AHX units per door. The CDS is mounted on the back of the cabinet and removes heat from the exhaust air.
The CDS offers a unique modular mounting system that can accommodate up to 3 AHX units per door. The CDS is mounted on the back of the cabinet and removes heat from the exhaust air. The doors are designed to allow full and convenient access to IT equipment. The CDS is lightweight and available in standard cabinet sizes. In addition, many cabinet manufacturers offer “OptiCool Ready” products that use existing mounting points.
For retrofits, OptiCool’s door transition kits provide convenient and seamless integration of the Cool Door System on to all major manufacturer’s cabinets. Doors can be configured to handle heat removal from 3kW up to 45kW per rack.
