By synergizing solar energy with heat pump technology, this solution represents a stride toward a greener and more sustainable future, reducing reliance on non-renewable energies and promoting cleaner air and a less carbon footprint, simply by using the Solar Assisted Heat Pump (SAHP). In this article, we’ll investigate an energy study of a SAHP aiming for further sustainable heating applications, our investigation centres on the system’s efficiency and potential energy losses under various conditions: when operating with a single compressor versus two, and comparing the impact of insulation versus its absence, to pinpoint areas for potential system enhancements. Utilizing CoolPack software, we conduct theoretical calculations of the Coefficient Of Performance (COP), aligning our findings with experimental measurements. The results show the importance of the insulation in reducing the losses within the system, we were able to conserve 90 W of heat power when the system was running with one compressor, and about 429 W when both compressors were in operation.
