Air-conditioners typically account for 65-70% of the electricity consumption in international schools in warm climates.

90% of the energy used by ACs is consumed by the compressor, the regulation of which is very crude.

Herein lies an opportunity for significant savings.

Most ACs use a single temperature sensor (thermostat) which results in the compressor doing unnecessary work, and the temperature in the room being either too hot or too cold.

Coolnomix is a device that can be retrofitted on the wall next to the AC unit to minimise wasted energy and deliver better temperature control. It uses dual temperature sensors and a patented ORS (optimised refrigerant supply) AI control system to continuously optimise the compressor run time.

Over 20,000 Coolnomix devices have been fitted worldwide for clients such as HSBC, 7/11, McDonald’s, and JW Marriot.

Coolnomix can be installed in 1 hour, has a 3-year warranty, and can improve energy efficiency by over 25% with a payback of 2 years or less.
