2.6.2 Liquid Cooling Package – LCP
The LCP is a temperature-neutral cooling concept with a maximum refrigeration capacity of up to 20 kW. The
LCP operates with cold water meaning that it requires a connection to the cold-water system provided by the
customer or to a return cooler for generating cooling energy. This system is optimally suited for cooling hot
spots.
The LCP operates in the modular safe completely independent from the ambient temperature. The gener-
ated heat is guided into the open via the cooling water circuit.
The control electronic components detect if a fan breaks down and then automatically control the fan rotary
speed of the remaining fan. Should a fault occur, the LCP can generate a message via the alarm output of
the control unit. All system-relevant parameters are monitored in combination with the CMC-TC. For this
monitoring to be performed, an input is needed on the PU unit.
The components of the LCP are designed to provide a long service life. The cold water connections and the
water filters have to be controlled regularly, must undergo regular random checks and be cleaned regularly.
The spatial separation of the water and air-guidance areas guarantees that no water can get into the server
area. Additional security is provided by using a leakage detector. If a leakage is detected, a magnet valve
can be triggered, respect. closed in the feed and return flow.
Benefits of the LCP usage:
• High efficiency
• Complete accessibility to the 19" level at the front and rear
• Absolute even distribution of the cold air in front of the 19" level
• Inclusion in a holistic surveillance system
• Active condensation management system
• The existing room air conditioner is not put under any strain
Advantage over air-cooled solutions:
The discharge of the stray power using water from the LCP creates an excellent separation between the
supplied cold air and discharged thermal energy. Thanks to its material characteristics, water can transport
thermal energy almost 4,000 times better than air.
