AI Technical Summary

Technical Problem

Classic thermal plants are highly polluting and expensive, and hybrid thermal plants require large, bulky components due to their dependency on external air temperature for heating refrigerant gas, leading to complex installations and high space requirements.

Method used

A two-stage component where a water/fumes exchanger and an evaporator are arranged within the same chamber, allowing fumes generated by a burner to heat both water and refrigerant gas efficiently, independent of external air temperature, with a compact design.

Benefits of technology

This configuration enhances efficiency, reduces component size, simplifies installation, and minimizes heat loss, resulting in a compact, easy-to-install unit with improved energy efficiency.
