Plasma Treatments for Evaporative Batteries
One of the main obstacles to the efficient operation of heat pumps under extreme weather conditions is the formation of frost on the evaporator coils. In this study, E2Tech tested innovative surface treatments applied to aluminum fins, aimed at reducing ice buildup and improving heat transfer capacity.
Through a detailed analysis of the hydrophobicity of materials, a vacuum plasma treatment was developed that led to the creation of superhydrophobic surfaces. Tests conducted on actual prototypes showed an increase in operating time before defrost cycles were required, with a significant reduction in efficiency losses. This approach not only improves the performance of heat pumps but also helps reduce energy consumption, making the system more sustainable.

Innovative Refrigeration Circuit for Residential Heat Pumps
The objective of this research was to develop an advanced refrigeration cycle capable of ensuring high efficiency even at high temperatures and enabling monovalent operation, thereby eliminating the need for additional heat generators.
The new design, featuring a dual lamination valve system and a regenerative heat exchanger, enables more stable and efficient operation. One of the main innovations is the ability to operate with zero superheat at the evaporator coil outlet, optimizing heat exchange with the source and reducing the need for defrosting.
Another advancement concerns the thermodynamic management of heat dissipated by the inverter, which is recovered and reintroduced into the refrigeration cycle, further improving the system’s overall efficiency. Laboratory tests and subsequent field tests have confirmed top-tier performance, with COP and SCOP values exceeding industry standards.
