I'll connect the dots for anyone who can't.

On April 27 Jian Sun did a presentation for the DOE about Dalrada's commerical heat pump validation.

This pertains to the GSA program Dalrada was accepted into with their heat pump. Here is the text from the GSA site itself.

promises to increase heating and cooling efficiency by capturing and reusing thermal energy while reducing global warming potential. Using carbon dioxide as the refrigerant, this heat pump can deliver cooling down to -22°F and heating up to 250°F.

Now lets go to this abstract for the Internation Communications in Heat and Mass Transfer, which the same person who presented for Dalrada at the DOE on 4/27 was involved with.

To enhance the capacity of heat pump water heaters (HPWHs), high energy density phase change material (PCM) was used in two experimentally tested HPWH prototypes. Preliminary findings showed that in the PCM, stored thermal potential energy could be effectively converted into sensible heat in the water over a slight temperature difference, with the goal of increasing the capacity of hot water above a desired cut-off temperature. This exchange of energy results in an increased amount of hot water necessary for mixing at the location utilized by the consumer. It was also found that for a wrapped HPWH, there was an average increase of 27.7% in the capacity when 7.6 L of novel PCM filled spherical capsules were added to a 22.7 L tank downstream of the HPWH. In the second design (Beta), PCM capsules were immersed into the tank with a cylindrical geometry, and the UEF was increased by 5.5% over the baseline HPWH test result. As for the Beta design, heat loss was reduced significantly compared to a typical HPWH and the Alpha design. Food-grade PCMs were selected as appropriate. The novel encapsulation design increased the effective conductivity inside the capsule by adding metal fins.

That is precisely what Dalrada has said about their heat pumps and this experiment is for our heat pumps. The conclusion from the experiment?

Conclusions

The results of experimental testing and review of the literature clearly shows that the capacity and system efficiency of water heating can be increased through the use of PCMs at medium storage temperatures (i.e., 40 to 80 °C). The drawback of poor thermal conductivity can be overcome by novel macro capsule design. The findings of this study found that the PCM capsule designs led to a significant increase in the FHR through the charging and discharging of PCM during each water draw of the FHR

Spin it all you want, this is amazing confirmation.
