Founder and CEO
Ahmed Hussein, PhD
He spent twelve years designing control systems for cars and aircraft, then started AReCoS to build a heat pump designed not to stop heating in the cold. He invented the two pieces it is built on: the embedded controller and the air–water heat exchanger.
At AReCoS
He works on the whole machine, from the refrigerant circuit to the controller.
Alongside him, Ahmed Atallah leads the physics modeling and holds a PhD in control from UC San Diego (Google Scholar).
- Heat pump design
- The all-season heat pump and rooftop unit, from the refrigerant circuit to the CAD geometry of its components.
- Air–water heat exchanger
- He designed and numerically optimized the air–water heat exchanger (patent pending). It is designed to hold frost to a thin layer and clear it while the unit keeps heating.
- Controls
- The embedded controller and its control strategies, carried through startup, running, shutdown and changeover.
- ORNL research
- He is the technical lead on the AReCoS research agreement with Oak Ridge National Laboratory, a CRADA: he tracks the milestones, runs the collaboration day to day and keeps the work pointed at what the program needs.
Background
Control, fluid mechanics, thermal systems and optimization.
Beyond the control algorithms, he has built the thermal systems and embedded controllers they run on.
Show the fluid mechanics and industry work
Fluid mechanics is the other half. For his PhD in engineering mechanics he modeled unsteady flow and fluid–structure interaction, wrote an unsteady vortex-lattice flow code in C++, and built reduced-order models of unsteady loads from wind-tunnel tests. In industry he built physics-based fluid-thermal models and optimal control strategies for electric-vehicle battery conditioning and cabin heating and cooling.
He is a Design for Six Sigma Black Belt and has published on dynamics, optimal control and vehicle energy; the papers are listed below.

Let's talk.
We're looking for pilot sites for the AReCoS heat pump RTU and manufacturing partners for the first builds. We also fit the embedded controller to your refrigeration system and the EV heat pump to your vehicle program.
