Mitsubishi Electric announced the development of a new plate heat exchanger for heat pump\u00b9 equipment used for heating and cooling, achieving approximately three times the heat transfer performance\u00b3 of the company’s conventional models.<\/p>\n\n\n\n

New Refrigerant Requirements Present New Engineering Challenges<\/h2>\n\n\n\n

The transition towards carbon neutrality is driving increasingly stringent requirements for refrigerants. This is accelerating the gradual adoption of solutions using refrigerants with a lower Global Warming Potential (GWP). At the same time, greater emphasis is being placed on safety and on optimizing the refrigerant charge within the system.<\/p>\n\n\n\n

This is driving the development of heat exchanger designs capable of delivering high heat transfer performance while reducing the required refrigerant charge.<\/p>\n\n\n\n

Further improvements in heat transfer performance are constrained by the limitations of conventional heat exchanger designs. Mitsubishi Electric investigated the use of micro-offset fins\u2074 between flat plates to enhance heat transfer. Testing revealed, however, that this configuration resulted in non-uniform distribution of the refrigerant’s gas-liquid two-phase flow across the entire plate surface.<\/p>\n\n\n\n

This represented one of the key engineering challenges in developing the new heat exchanger.<\/p>\n\n\n\n

How the New Technology Works<\/h2>\n\n\n\n

To achieve more uniform flow distribution, Mitsubishi Electric developed specially designed distribution channels at the refrigerant inlet and outlet.<\/p>\n\n\n\n

These channels enable uniform distribution of the refrigerant’s gas-liquid two-phase flow across the plates. The channel arrangement was optimized using Mitsubishi Electric\u2019s proprietary analytical technology, which simulates the complex flow behaviour of two-phase refrigerants between the fine fins.<\/p>\n\n\n\n

As a result, Mitsubishi Electric has achieved industry-leading\u00b2 heat transfer performance while reducing the required refrigerant charge.<\/p>\n\n\n\n
