Micro-channel heat
exchangers extended from Aquaforce to Aquasnap by Carrier
Enhanced corrosion resistance and extra
efficiency are to be offered on Carrier’s established and popular Aquasnap
chiller range with the substitution of the highly effective all-aluminium
micro-channel heat exchanger (MCHX) technology in place of traditional heat
exchangers.
Conventional copper/aluminium coils will still
be available on some units as a factory-fitted
option but the efficiency of the new technology is such that Carrier expects
only limited requests for this once the market has adjusted to the change.
The MCHX technology has proven to be a great success
on Carrier’s Aquaforce range of chillers. This micro-channel heat exchange
technology has been widely used in the automotive industry for some years, but
Carrier’s use of it in the Aquaforce was the first time it has been applied in
large chillers.
MCHX has been shown in field trials and customer
installations to increase heat transfer efficiency. The all-aluminium, brazed
construction coils provide enhanced reliability through improved corrosion
resistance. The overall weight of the chiller is also reduced.
Perhaps most importantly of all, condenser coils with
micro-channels require up to 40 percent less refrigerant, further improving the
environmental qualifications of this technology and Carrier’s chiller range.
