COLDINNOV process : refrigeration through waste heat recovery
COLDINNOV develops a patented breakthrough innovation : a thermochemical reaction recovers residual heat to use it as an energy source for refrigeration. This process is based on the adsorption of ammonia by a reactive mixture developed by COLDINNOV, inside a reactor.
Benefits of COLDINNOV technology :
- Recovers residual heat as an energy source
- Generates energy savings by over 80% compared with a compression system
- Uses a natural refrigerant fluid with no impact on the environment
- Cooling effect to above- or below-freezing as soon as it is started up
- Reduces maintenance costs thanks to the absence of moving parts in the reactor
- Allows for direct conversion of heat into cold or for its storage in chemical form
Residual heat as an energy source
The different solutions which COLDINNOV is planning on marketing vary according to their refrigeration power, and therefore according to their dimensions, though they are all based on a similar technology and architecture. The developments undertaken by COLDINNOV are common to all applications.
COLDINNOV can be installed :
- As a replacement to an existing refrigeration unit
- As a complement to an existing refrigeration unit
- As a new refrigeration system
The ammonia, a refrigerant for the future
- It has no effect on the ozone layer and no greenhouse effect, unlike the fluids known as HFCs and HCFCs, which are subject to specific regulations,
- It is the highest-performing fluid in terms of refrigeration,
- Its low cost means it quickly becomes competitive for high power systems.
The ammonia is still not widely used because of the difficulty of its implementation. Its corrosive effect makes the performing and airtight compression systems complex and costly.
COLDINNOV process is based on a sealed and soldered reactor to eliminate potential leaks. The corrosive effect of the ammonia is then controlled as a result of the simple design of the reactor.
The 3rd generation of HECO/S reactors are longer than HECO/S V2 reactors and cannot be dismantled.
