MQue Reaches Phase C of NEDO Heat Pump Program
The heat exchanger is where empirical design tools lose accuracy once refrigerants and geometries change, so MQue's Phase C proposal is aimed at the part of the low-GWP transition that forces experiment-based trial and error.

MQue Inc. has been selected for Phase C of NEDO's New Energy SME and Startup Support Program, moving up from Phase B in fiscal 2024, the company announced. The Phase C work runs two years, from October 2026 to September 2028, and covers a heat pump heat exchanger design platform built on computational fluid dynamics, AI surrogate models, and design optimization. The stated target is the shift to low-GWP refrigerants such as propane.
The theme selected is development of a heat exchanger design platform for heat pumps across diverse applications. In a heat exchanger, refrigerant repeatedly boils and condenses into a gas-liquid two-phase flow, a condition MQue says is hard to predict. With propane (R290) and other low-GWP refrigerants, MQue says the empirical-formula tools common in the industry lose accuracy and calibration data takes time to prepare, pushing design toward experiment-based trial and error. MQue plans to build the platform around CFD, AI surrogate models, and optimization, with an eye beyond household air conditioners to commercial and industrial heat pumps.
