Page 9: Device Description
3 Device description Device description General functional description The Liquid Cooling Package DX (DX = Direct Expansion) is essentially a split air conditioning unit used to dissipate high heat losses from server enclosures or for the effec- tive cooling of devices built into a server enclosure. The air routing in the LCP DX supports the "front to back"... -
Page 10: Lcp Rack Dx
3 Device description In order to ensure targeted air routing in the system, the server enclosure should be divided vertically into warm air and cold air sections. The division is accomplished in the front section of the server assembly to the left and right of the 482.6 mm (19") level using foam strips or air baffle plates which, depending on the enclosure width and the number of server enclosures to be cooled, can... -

3 Device description Equipment assembly Note: However, the system does not need to be 3.3.1 Unit components completely airtight, thanks to the high, co- ordinated air throughputs of the server and LCP fans. 3.2.3 LCP Inline DX Targeted air routing by hot air extraction from the hot aisle and cold air blown into the cold aisle has a funda- mental effect on the amount of heat to be dissipated. -
Page 12: Coolant Circuit
3 Device description – Electronic expansion valve: The expansion valve sup- plies the evaporator coil with the required volume of coolant to provide the corresponding cooling output in the current ambient conditions. – External condenser: The condenser is sited outdoors from the room where the LCP DX is situated. -
Page 13: Fan Module
3 Device description 3.3.4 Fan module Proper and improper usage The LCP DX is used to dissipate high heat losses and ef- fectively cool devices built into a server enclosure. The unit is designed solely for static use in sealed rooms. The unit is state of the art and built according to recog- nised safety regulations. -
