The Regulating Energy Efficiency Device (REED) is a revolutionary energy saving and leak mitigating technology developed for commercial HVAC-R. REED was designed around the second law of thermodynamics, utilising normally wasted energy to improve system efficiency. REED harvests and stores refrigerant energy which is lost through normal system operation. REED then uses this ENERGY like a battery to reduce system energy requirements, saving electricity and reducing system wear, which extends plant life.



REED is a sub system which for the first time opens the refrigerant circuit to allow for dynamic refrigerant optimisation and is also able to store refrigerant as energy (high-pressure liquid refrigerant). REED adjusts the amount of refrigerant charge in the system to perfectly match the load and environmental requirements, whilst storing any removed refrigerant as high-pressure liquid energy, meaning that when it is returned to the system the compressor does not have to recreate this work (energy).



REED can generate energy savings of up to 27.6% and work on systems from 60kW to 2 Mega Watts. All while only using the electrical power of one incandescent light bulb. REED is a revolutionary stand-alone energy saving device however, as it saves energy in a completely unique way, it can be installed in conjunction with existing energy saving technologies to compound energy savings.



Every established HVAC-R system of any age will over time experience refrigerant leakage. As REED is fluidly connected to the system & constantly adjusting the refrigerant charge, it is also able to detect with incredible accuracy and precision the refrigerant charge level of the system + therefore it can detect system leaks and micro leaks with an averaged accuracy of 0.01137% (24-hour period), far exceeding any other leak detection solution.



Stakeholders of HVAC-R equipment are continually trying to improve design and performance of their plant & equipment as this is a direct cost of business with any improvement directly effecting their bottom line. The REED™ system is easily retrofittable to any existing or newly installed HVAC-R and generates instant benefits: reduced electrical costs and minimised systems environmental impact.
