Graphene Manufacturing Group Ltd (TSX-V:GMG, OTC:GMGMF) (GMG) has announced further results of energy savings tests on a 4.3 kilowatt refrigeration system and heat transfer demonstrations on aluminium and copper, in which the company says the results provide additional confidence in the potential benefits of THERMAL-XR (TXR) in a range of applications.
The clean-tech company said the THERMAL-XR coated coil resulted in 15.7% energy savings and a 16.1% time savings for the Pull Down test, which assessed the time and energy required to reach a set temperature of 2 degrees Celsius in the heat controlled room with an initial set temperature of 30 degrees Celsius, controlled constant humidity level, and an outdoor temperature of 35 degrees Celsius.
GMG also noted that the THERMAL-XR coated coil delivered 4.69% energy savings for the 48-hour Temperature Cycle test, which measured the energy required over a 48-hour period to keep a cooling set temperature of 2 degrees Celsius in a heat-controlled room with an outside temperature of 35 degrees Celsius and controlled constant humidity level.
“The graphene-enhanced heat transfer properties of THERMAL-XR have demonstrated that the performance of a new coil can be enhanced,” GMG CEO Craig Nicol said in a statement.
“This has significant potential for our targeted market of new air conditioners or Original Equipment Manufacturers (OEMs), as well as our existing target market of installed air conditioners,” he added.
As well, Nicol stated that the graphene-enhanced heat transfer properties of THERMAL-XR seemingly outweigh the traditional insulating effect of coatings when cooling.
THERMAL-XR powered by the GMG Graphene coating system is a unique method of improving the conductivity of heat exchange surfaces, resulting in an efficiency improvement and a potential power reduction when applied to air conditioning condenser coils or other industrial processes needing heat transfer, according to the company.
GMG is a clean-technology company that seeks to offer energy saving and energy storage solutions, enabled by graphene, including that manufactured in-house via a proprietary production process.
