Frequently Asked Questions about COOLNOMIX® technology

COOLNOMIX® optimizes the operational run-time of the cooling system compressor. Since the compressor accounts for ~95% of the power consumption of a cooling system, optimizing its run-time can deliver very large savings. 

 COOLNOMIX® employs two temperature sensors – one to regulate the room/space temperature delivered, the other to measure the cold-supply air temperature. The latter is used to determine when the hydraulic work of the compressor is completed – when the refrigerant gas is fully compressed. 

 Once this reservoir of cold-supply has been created, COOLNOMIX® stops (non- inverter) or slows down (inverter) the compressor until further hydraulic work is needed. It is the compressor off-time or slowed-time that delivers the astonishing energy savings. 

The internationally patented process Optimized Refrigerant Supply (ORS®) which is incorporated in COOLNOMIX® has specific protection included within its function. 

 This includes protection against too frequent stop-start of the compressor and assurance that every re-start is always a soft-start – the re-start of the compressor is never under load since the suction and discharge pressures are guaranteed to be in equilibrium. As a result there is no adverse effect on the operational life of the compressor of the cooling system.

ORS® incorporates a priority on delivering the required room/space temperature – energy savings will be sacrificed in order to ensure the room/space temperature is achieved. COOLNOMIX® typically improves temperature control in air-conditioning and refrigeration systems. In contrast with most installations having room/space temperature variations of 1-2°C (1.8-3.6°F), our dual temperature sensor approach commonly limits room temperature variations to 50% of that experienced without COOLNOMIX®.

COOLNOMIX® delivers energy savings on air-conditioners of any size and any kind, including:  

Commercial split-type air-conditioners (e.g. wall mounted or ceiling cassettes) 

Package based and double expansion (DX) units up to the largest sizes available ducted AC’s with AHU’s Inverter based (VRV and VRF) AC’s.

We have inbuilt short cycle protection in COOLNOMIX®. This means that even if we were to take control of the compressor directly (something we do not recommend) or if the manufacturer provided control system does not have inbuilt short cycle protection we have built this into our technology design. 

A result COOLNOMIX® will never allow the compressor to run for less than 3 minutes and it will never allow the compressor to be off for less than 3 minutes.
