Introduction HOW DOES ACES WORK?  Air conditioning systems are usually dimensioned to cope with the extreme cooling demands of the few hottest days of the year (plus a safety margin). However, in most operational conditions, this maximum output is not required and the system is oversized. So running the system continuously until the room thermostat switches it off means that the system operates with excess capacity for most of the time.

This is where an ACES cuts in. Its sensor-driven software algorithms are designed to detect thermodynamic saturation and to optimise the compressor accordingly. When over capacit y is detected A C E S switches the compressor off and thereby avoids inefficient overcooling (see diagrams below).

 ACES switches into “saver mode”, the fan keeps running and your system makes maximum use of the stored cooling energy in the heat exchanger. Once the stored energy is used up, the compressor can work efficiently again and is switched back on. The set room temperature is reached wit hout t he inefficient parts of t he cooling cycle. This results in signifi cant energy savings wit hout real compromise in cooling comfort .
