Munters SyCool® Split – 250 kW
Indirect Economizer Thermosyphon Split-System
SyCool Split 250 kW Indirect Economizer Thermosyphon Split System
Munters SyCool Split provides an efficient cooling solution for new and retrofit installations where access to a suitable water supply may be limited, expensive or unreliable.
Advantages
- Split system eliminates duct penetrations
- No water consumption
- High-efficiency economization
- Factory-optimized controls
The
system nominal cooling capacity is 250 kW. Thermosyphon heat exchangers move
heat from the data center to ambient through the evaporation of liquid
refrigerant in the SyCool evaporator, and condensing of the same refrigerant
in the SyCool condenser. The evaporator is connected to the condenser with
refrigerant piping allowing up to 500′ of separation (see installation manual
for specific fitting losses). As long as the condenser receives air cooler
than the evaporator, heat is exchanged passively for “free cooling” of the
data center. A simplified version of the system is schematically shown in
Figure 1, right.
The SyCool 250 thermal effectiveness is nominally 65%, which greatly exceeds
that of competing refrigerant based economizer systems. For example, with air
delivered to servers at 75°F and a 20°F delta T across the servers, SyCool
achieves 100% free cooling when the ambient dry bulb temperature is 62°F or
lower (operating at 75% load). As ambient temperature rises, SyCool
transitions from passive to active by staging/modulating compressors located
in the condenser section. Data center heat is rejected by the thermosyphon,
passively or actively without the need for diverting valves, allowing seamless
transition from economizer to active cooling. As the ambient temperature
approaches the temperature from the servers, SyCool finally loses free cooling
capacity. The high heat exchange effectiveness coupled with the ability to
economize simultaneously with active refrigeration, yields best-in-industry
economizer capture efficiency.
