Japan, Sept. 14 -- Mitsubishi Electric Corporation announced that it has developed a plate heat exchanger for heat pump cooling and heating equipment with industry-leading heat transfer performance - triple that of conventional models. Specifically, the new heat exchanger reduces the number of plate layers allowing the refrigerant charge to be reduced to approximately one-third that of conventional levels, resulting in lower environmental impact and improved safety.The urgent need to achieve carbon neutrality has led to stricter refrigerant regulations, requiring a shift to next-generation refrigerants and a reduction in the refrigerant charge in heat pump cooling and heating equipment. While next-generation refrigerants like R32 have a low...
