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 runtime 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 ully 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.
