An international research team has conducted a computational analysis on propane (R290) vapor compression heat pumps integrating a thermoelectric subcooler (TESC) to increase the coefficient of performance by 12.29%. The study shows that TEMs and solid-state heat engines are used in TESC, benefiting refrigeration systems. The TESC is placed between the condenser and the internal heat exchanger, providing subcooling by absorbing heat from the propane. The research team found optimal TEM voltage levels crucial for maximizing heat pump efficiency.
