The researchers tested a new refrigerant called R430A in a solar thermal heat pump system to replace the harmful R134a. They found that R430A uses less energy, heats better, and has a higher efficiency than R134a. The system using R430A also has lower global warming impacts. Overall, R430A is a more environmentally friendly option for heat pump systems.
