Models CW-H10, CW-H15
Indirect Evaporative Air Conditioner
GENERAL
Climate Wizard is an “Indirect Evaporative Air Cooler” that is capable of delivering cooled air, with no
added moisture at temperatures that are very similar to those produced by refrigerated air
conditioners. The Climate Wizard comprises of one (1) backward curved, high pressure,
centrifugal fan directly connected to an electronically commutated motor (ECM), a multi-patented
heat exchanger core, a water reservoir and water distribution system including circulating centrifugal
pump(s), automatic chlorination device and an auto water management feature.
Climate Wizard cannot remove moisture, but it does not add any moisture.
Climate Wizard is manufactured in two configurations - HORIZONTAL and VERTICAL. This
Application Guide refers to the HORIZONTAL configuration only.
The heat exchanger core may comprise of 2 or 3 sections.
The 2-section model is the CW-H10, with nominal cooling capacity of 10 KW*
The 3-section model is the CW-H15, with nominal cooling capacity of 15 KW*.
* [Cooling capacity is calculated at inlet conditions of 38
0
C dry-bulb and 10
0
C dewpoint temperatures, in accordance with Australian Standard AS2913-
2000. For other conditions refer tables on page 5. This capacity applies only when the Climate Wizard is being used in Stand Alone Cooling
applications. For Cold Front Cooling higher capacities apply - refer table on page 9.]
Not all the inlet air is delivered into the building. Inside the Climate Wizard the air is divided into
two streams..One stream is supercooled and delivered into the building, and the second stream is
used to intensify the wet-bulb depression, is supersaturated and discharged to atmosphere along
with all the heat that has been removed from the dry fresh air stream.
External Static pressure affects the behaviour of the two air streams inside the machine. A means
of compensating for the external static pressure will be provided on the Climate Wizard depending
on the application - see later information in this Guide.
