COOLNOMIX is an intelligent control system which improves energy efficiency in refrigeration and air conditioning systems by replacing the thermostat in a compressor driven cooling system. In the traditional cooling system, most of the manufacturers do not take into account the hydraulic work of the compressor. The compressor of a traditional cooling system continues running even if the hydraulic work is done and space is already at its desired temperature. This wastes energy as 95% of the costs of operating air conditioning and refrigeration systems come from the compressor itself.
This thesis aims to study the effectiveness of COOLNOMIX by doing some practical experiments to investigate the amount of energy saved by COOLNOMIX and how COOLNOMIX is being affected by Western Australia climatic conditions. Three different experiments have been investigated in this thesis, which are practical experiment for air conditioning, practical experiment for refrigeration system and existing experiment of a cooling system. Practical experiments were designed and researched by installing COOLNOMIX product in air conditioners and a cool room at Murdoch University and let it run for a period of time to investigate the energy saved and the system performance under different climatic condition. The existing experiment of a cooling system is to analyze the data of a cool room which already having installed COOLNOMIX product in real life.

The results of the air conditioning system experiment showed that the COOLNOMIX is saving 14% of energy during hot weather and 20% of energy during cold weather. For the refrigeration system, COOLNOMIX saves up to 53.5% of its original energy consumption.
