Conceptual rendering of Thevu Energy’s modular air-cycle cooling and shaft-work recovery system.

Energy recovery, built in.

The platform is designed to convert part of the mechanical energy available during operation into electrical output. Its practical value depends on the complete system and application.

Air is the working fluid.

Thevu Energy’s approach avoids circulating a phase-change refrigerant through a conventional evaporator loop, creating another option for applications where refrigerant constraints matter.

01

Air intake

Ambient air enters the system.

02

Compression

Compression

Air pressure is raised.

03

Heat transfer

Heat transfer

Heat is transferred away from the compressed air.

04

Air expansion

Air expansion

Pressure falls and the air cools.

05

Cold air output

Cold air output

A colder supply stream leaves the system.

Air path

Manage pressure and heat to produce a colder air stream.

System view

Cooling performance, total electrical input, auxiliary loads and any usable recovered output will be evaluated together.

Performance values remain to be measured.

Where the platform may fit.

Start where cooling value is easiest to measure. • INITIAL FOCUS: Localized industrial cooling for work cells and test areas, plus defined equipment and enclosure loads that can be isolated and metered. • NEXT: Small data rooms and telecom spaces, specialty outside or make-up air, and selected battery-storage enclosures, subject to application-specific validation. • LATER: Whole-building comfort, vehicles and cold chain after seasonal efficiency, acoustics, durability, safety and installed cost are established. Initial testing will focus on moderate-to-warm inlet conditions; broader climate capability and usable recovered output remain to be measured across the complete system.

Patented air-cycle system.
