Chillers are the only way of beating the heat, when summers
are near. The increased level of humidity in the air often makes people sweat
profusely and serves as a breeding ground for bacteria and parasites. The humid
air circulating indoors may aggravate sickness and allergic conditions, leaving
the atmosphere unhygienic. Dehumidifier's purify air indoors, rendering it
fresh and safe to breathe in. Created for industrial purposes, these dry air Dehumidifiers
are now progressively used in every new business set-up and household.
Chillers are basically a closed system, which utilizes the
process of evaporation and condensation to cool the air in a room. Making use
of drying technology, the dry air system cools the temperature by passing on
the heat from the source to the evaporator coil. Basically, there are two kinds
of chillers. One is air cooled and the other being water cooled. Air cooled
chillers, as the name suggests uses air to dehumidify a space, whereas water
cooled chillers uses water to cool a place.
There exists no formulae to find the perfect dehumidifier
and neither of them would be suitable to every device. Each chiller has its own
set of advantages and disadvantages and a buyer should effectively scrutinise
them before investing in one. Space is one of the most important factors, when
it comes to choosing a Dehumidifier. Air chillers are larger in size and
require a large space for installation, whereas water cooled chillers are
small, but require cooling towers and a mechanical room for effective
functioning.
Air cooled chillers would be unfavourable for industries,
which have walls higher than the unit. They require continuous flow of fresh
air and an obstructed air flow may create problems with recirculation. Water
chilled coolers are more suitable, when there's a lack of space and restricted
air flow.
Every chiller produces a noise when it is in use. The noise
of air cooled chillers cannot be determined as each fans installed in them
would have a different decibel. Although, there are various ways to decrease
the noise produced by them, it is always better to invest in a system, which is
quieter. Air chillers are normally cheaper compared to the money spent on the
maintenance of water chillers. The air coolers require less maintenance and
don't need cooling towers, condenser pumps or a mechanical room to function.
However, the life
span of air chillers is short and is less efficient compared to water chillers.
Water chillers on the other hand, have a greater life span and work efficiently
with continuous maintenance. Lifespan and the performance of the chillers
depend on the quality of the chiller you choose. Ideally, it is always better
to consult your local contractor before purchasing one.
