Abstract
Indirect evaporative cooling is considered as an energy
efficient, environmentally friendly, CO2 emissions
reduction and sustainable method. The most significant
advantages of indirect evaporative cooling system is
expressed by being able to achieve ultimate temperature
to dew point temperature, and having constant moisture
content in cooling process. Such air cooler strategy
accomplishes by single stage regenerative-counter flow
principle, in which air flows into the dry channel
manipulated to the wet channel. This is implemented in
the end of dry channel and causes the dry air to be
cooled before branching to the wet channel. Also, the
novel wet-surface heat exchanger is explained by modified
effectiveness-NTU method. The aim of this research is to
model and simulate a novel cooler to produce comfort
environment for office room case study in Helsinki, and
analyze the result of cooler performance. Simulating the
wet-surface heat exchanger, as the new component of the
dynamic simulation environment software such as IDA
Indoor Climate and Energy (IDA ICE), needs to be modeled
in the Neutral Model Format (NMF) environment. Then, the
mathematical model is able to be added in IDA ICE 4 and
simulate the case study in various climates.
Consequently, such heat exchanger is capable to prepare
the comfort indoor conditions and omit electrical cooling
energy demand for vapour compressor machines in Helsinki
regions.
