energy savings & carbon reductions...

RiEnergy ORS® Technology...

from hfmcare

In most refrigeration units and air-conditioning applications, a lot of energy is wasted because the unit’s compressor (the main running cost) runs much longer than is needed.

Using our patented process called Optimized Refrigerant Supply® (ORS®) the advanced RiEnergy control device reduces the run-time of the cooling system compressor, therefore, reducing electricity consumption...

Even in the most demanding high and humid environments!

RiEnergy ORS® Technology...


The RiEnergy ORS® technology uses two temperature sensors in an algorithmic energy trading control arrangement to monitor the thermodynamic (room or space temperature) and the hydraulic (refrigerant supply) performance of the connected air-conditioning or refrigeration system.

In operation this algorithmic energy trading approach first uses the room or space temperature sensor to ensure that a required setpoint has been achieved.

Subsequently, this temperature sensor ensures that the space is maintained within +/-0.5°C (+/-0.9°F) of the required setpoint. Meanwhile, a second temperature sensor connected to the indoor evaporator coil is used to identify when the compressor has done its useful hydraulic work in producing a supply of high-pressure liquid refrigerant.

Using the built-in algorithmic energy trading control, the RiEnergy ORS® advanced system then starts and stops the compressor at appropriate times to optimise running costs.
