Glaciem Cooling Technologies in conjunction with researchers from the University of South Australia have developed a unit, based on a CO2 refrigerant that uses dew point technology to pre-cool air before it enters the refrigeration system’s condenser.
The system also has a thermal energy storage component that can store excess electricity from sources such as solar PV. The -6 degree Centigrade Phase Change Material (PCM) storage system can then release the thermal energy as cold air to run the refrigeration system when electricity prices are high. Details can be found at http://theleadsouthaustralia.com.au/industries/manufacturing/cool-solution-for-co2-refrigeration-in-hot-climates/ and http://www.glaciemcooling.com/ . Glaciem’s ThermCOLD systems can utilise novel PCMs with 0, -6, -11 and -27 degrees Centigrade melting points.
