Description

Moisture with salt and small fine sand particle it’s harmful when combined in tropical hot climate onto HVAC environment application sites. The concept of urban carbonic island, where carbon dioxide is the pollutant that performs as a chemical marker, responsible for decreasing productivity at air-conditioned environments with uncontrolled indoor gas rates, in addition typical contaminants in indoor hot climates environment. The psychometric conditions establish high thermal loads especially from May to August, when temperatures fluctuates between 46°C (115°F) to 30°C (86°F) respectively, while high humidity varies throughout the day from 25% to 82%, a thermal conjuncture challenge. Characterizing pollutants as multimodal, it’s composed by particulate matter, marine mist and gas beyond the adverse enthalpic conditions. The hydrodynamic precipitator (PH) is characterized by the associated combination of centrifugal mixing power, the multiventuri effect, which results in gas mixture of mass and energy transfer between gas mixtures, pollutants and cooled liquid neutralization, gives us safe ground to present HVAC technology to Make Up Air for outdoor air applications, from urban air suction to HVAC systems, industrial plants, electrical rooms pressurization, telecommunication centers, data centers and air taken to turbine combustion processes or polymers pellets pneumatic transfer. As well in application to remove salt, hydrogen sulfide and decrease high levels of carbon dioxide, demonstrated the high performance of air cleaner, all based in multiventuri centrifugation technology. It’s the theory of breadth molecular convergence vibration reached by this concept, becoming compact due to instantaneous removal of contaminants, based on centrifugation technology of two fluids simultaneously.

The reduction of carbonic load through chemical alteration of carbon dioxide in a salt increases the life cycle of conditioned air, allowing external air flow reduction, impacting in significant decrease of 23% to 28% in energy consumption, as well as guaranteeing indoor air pollution control. The hydrodynamics precipitators are independent units that extract physicochemical pollutants, without the use of mechanical filters, lowering external thermal load for both arid and hot climate application. The presence of submicron silica particles which TLV-ACGIH (2012) = 0,025 mg/m3 defines the BADCT (Best Available Demonstrated Control Technology) use ensures high performance for this particles avoiding generating saturation of mechanical filters. This technology is an innovation of external air taken because acts simultaneously in the removal of multimodal contaminants and reduction of thermal load.
