Abstract

This Addendum formally discloses two novel extensions to the ALLFROMAIR® TERRA² Tri-Generation Platform. The disclosures are presented with thermodynamically verified calculations for two primary climate scenarios: Desert (40°C/30%RF) and Tropical Max (40°C/80%RF).

The first disclosure — SVRU4 Cascade Condensation — establishes a fourth condenser unit (SVRU4), constructed identically to SVRU1, positioned at the exhaust of Module 2 after SVRU3. SVRU4 condenses water from the moisture-saturated exhaust stream (32–34°C/100%RF) using seawater or a night-cooled buffer as cold medium. This produces an additional 172,000–280,000 L/day in desert and 213,000–322,000 L/day in tropical conditions depending on cold medium temperature.

The second disclosure — Diurnal Thermal Loop — establishes that the desert night wet-bulb temperature (15.4°C at 22°C/50%RF) enables buffer pre-cooling via a dry air cooler (fan-driven, zero water consumption, ~30–50 kW) to 17–20°C. This buffer supplies SVRU4 with cold medium, substantially improving yield. Night-time compressor operation at COP 4.8 (+72% vs. daytime COP 2.8) enables optional deep cooling of the buffer to 8–12°C. In tropical coastal installations, direct seawater replaces the buffer loop entirely. Return water from SVRU4 and SVRU3 is combined, oxygenated via Venturi injector, and returned to sea at controlled temperature by AI-CORE flow regulation.

A key architectural refinement is disclosed: HX4 (heat pump evaporator/scavenger) is repositioned to operate after SVRU4 on the cooled exhaust air (22°C), improving heat pump COP by 60–101% compared to operation on uncooled exhaust (32–34°C). SVRU4 construction is identical to SVRU1 (Heresite P-413, 316L SS, direct condensation on cold surfaces), using the standard TERRA² component set without new technology.
