Carrier applies the micro-channel heat transfer technique
used in aviation and automobile to the central
air-conditioner successfully for the first time. The heat
transfer efficiency is improved by 10% and the air
resistance is reduced by 50%, compared with
conventional copper-aluminum fin coil. The full-load
cooling efficiency of the chiller shall rise by 2% and the
energy saving effect is much better. Pro-Dialog Plus microcomputer control system specially designed for
the air-cooled liquid chiller perfectly features the easy and
convenient operation and the advanced ad complicated control
concept for the central air-conditioner. The system monitors all
operating parameters and safety device in real time, precisely
manage the compressor, electronic expansion valve, fan and pump
(built-in hydraulic module for option), to make the chiller operate with
the optimum energy efficiency.
