Abstract

Disclosed is a concept of Hybrid Coolant Distribution Unit (CDU) which has mainly 3 functions They are reservoir tank, circulation with distributor and refrigerator by a few kinds of coolants/refrigerants which are customer water, coolant and refrigerated air etc, at once. Especially flexible combination in several refrigerants/coolants which has different thermal charactors is the most unique advantage. In other words, it's only required to supply refrigerants which have totally enough capacity in any time.

Hybrid Coolant Distribution Unit

      Disclosed is a concept of Hybrid Coolant Distribution Unit
(CDU) which has mainly 3 functions They are reservoir tank,
circulation with distributor and refrigerator by a few kinds of
coolants/refrigerants which are customer water, coolant and
refrigerated air etc, at once.  Especially flexible combination in
several refrigerants/coolants which has different thermal charactors
is the most unique advantage.  In other words, it's only required to
supply refrigerants which have totally enough capacity in any time.

      The advantages of Hybrid CDU concept are to enable more
flexibilities of facility planning in high heat load mainframe
installation by having;

1.  Flexible refrigerants/coolants combination available

2.  Compensation function between some refrigerants in any time

3.  Minimum total refrigeration capacity required

Applicable refrigerant or coolant are as follows.

o   Customer water (including Ethylene glycole etc.)

o   Coolant/Refrigerant (Ex: Freon, Ammonia etc.)

o   Refrigerated/conditioned air

Concept design and one reference are shown in Figs. 1 and 2
respectively.

o   Customer Coolant & Refrigerated Air type
