How It Works

Direct expansion (DX) cooling systems have design flaws that cause excessive running of the compressor, resulting in wasted electricity and associated GHG emissions.

The compressor is the single component in a HVAC system that uses the most energy: 50-90%, depending upon the use case.

COOLNOMIX is a dual-sensor supplemental control that once installed immediately boosts the energy efficiency of a cooling system by helping the control system to improve temperature stability and use less compressor runtime.

COOLNOMIX is introduced into the cooling system circuitry in series between the existing thermostat and the control unit. 

COOLNOMIX two hard-wired precision temperature sensors are installed in a different location than the thermostat.

The data inputs from the sensors are processed by COOLNOMIX artificial intelligence embedded software to help the control system improve temperature stability and determine how long the compressor should be on and off.

COOLNOMIX also has built-in compressor health safeguards that ensure the compressor has soft starts and runs for minimum durations.     

COOLNOMIX has been proven to decrease compressor runtime even as the outdoor temperatures increase.  

COOLNOMIX software works differently depending upon the the heat-load. Under low heat loads, COOLNOMIX helps the control unit not to over cool the space, thereby, using less energy. Under high heat loads, COOLNOMIX help the control unit to give the compressor a short rest, once it has completed the cycle of compressing a vapor into a liquid, and running any longer will give off heat.

As a supplemental control, COOLNOMIX can only assist if the thermostat or other control unit is calling for compressor run-time.

COOLNOMIX US patent is based upon using a combination of thermodynamic and hydraulic control to manage the on and off state of the compressor, which is the main energy consuming component. Thermodynamics is used to satisfy comfort levels with the room or space being cooled. Hydraulic control is used to determine when the compressor has completed its efficient work in delivering a supply of high-pressure liquid refrigerant. Once temperature and hydraulic conditions are satisfied the compressor can be held off, thereby delivering a significant reduction in running costs.

In refrigeration applications, COOLNOMIX offers additional functionality, as one of the sensors is installed near the evaporator coil. COOLNOMIX prevents ice from forming that could block the air flow, eliminating the need for costly defrost cycles or a service call to melt the ice.
