i-TES Patent: PCM-based device
Phase change material (PCM) terminal heating device
The first patent concerns a heating device, specifically an internal terminal for domestic or industrial use.
Patent number 102019000021033.
Grant date: October 21, 2021
Latent heat thermal storage battery
The second patent concerns a thermal storage device, specifically a latent heat battery (PCM). Compared to conventional solutions, its unique feature lies in its charging method: in addition to standard hydronic or electric systems, this battery integrates direct charging via the heat pump's refrigerant gas, operating in both heating and cooling modes. This configuration allows for direct coupling between the battery and the heat source, maximizing exchange efficiency and minimizing process losses.
Patent number 102021000001091.
Grant date: January 26, 2023
i-TES Patent: hybrid charging (hydronic, electric, and gas)
i-TES Patents: Preheating and Exhaust System
Integrated heat generation system and related heat generation process
This patent application was filed jointly (I-TES owns 50% of it). Specifically, it involves a thermal energy production system that combines multiple sources (cogenerator, solar and photovoltaic systems, heat pumps) and in which the i-TES battery acts as an integration element between all these sources. The battery stores the heat produced during peak production efficiency hours, then releases it during peak load and times of increased user demand.
Patent number: 102023000012360.
Grant date: June 20, 2025
