7 Temperature Control System
7.1 System Overview
The cooling system uses in-row air cooled smart cooling products and an aisle containment
for cooling. The in-row air cooled smart cooling products and equipment cabinets form an
aisle containment to separate hot air from cold air.
An in-row air cooled smart cooling product works as follows: After the unit starts, the
low-pressure refrigerant vapor in the refrigerating system is suctioned into the compressor,
compressed into high-pressure vapor, and discharged to the condenser. The outdoor air drawn
in by the axial flow fan flows through the condenser and carries away the heat emitted from
the refrigerant so that the high-pressure refrigerant vapor condenses into high-pressure liquid.
The high-pressure liquid passes through the filter and flow regulating mechanism and then is
ejected to the evaporator. Then the liquid vaporizes at low pressure and absorbs ambient heat.
The cross-flow fan draws air into the fins in the evaporator to exchange heat and discharges
cooled air to the cold aisle. The indoor air flows cyclically to decrease the temperature.
In-row smart cooling products are close to heat sources, which shortens the air supply
distance, reduces airflow pressure loss and cold air loss, and maximizes the use of cooling
capacity.
7.2 NetCol5000-A025 Smart Cooling Product
This section describes the components, operating environment, and technical specifications of
the NetCol5000-A025 In-row Air Cooled Smart Cooling Product (25 kW smart cooling
product for short).
7.2.1 Indoor Unit Components
Dimensions
Dimensions (H x W x D) of the NetCol5000-A in standard configurations are 2000 mm x 300
mm x 1100 mm, as shown in Figure 7-1. The equipment depth can be extended to 1200 mm
by adding an enclosure frame to the front door.
