Magnetic refrigeration

HISTORY

The physical principle

Magnetic refrigeration is based on the Magnetocaloric Effect (MCE). The MCE implies that the temperature of suitable materials (Magnetocaloric Materials, MCM) increases when they are exposed to a magnetic field and decreases when they are removed from it, that is, the effect is reversible and almost instantaneous.

 

The temperature with the strongest effect (the Curie temperature) depends on the properties of each material. The power generated by the system depends on the type of materials and their characteristics (mass and shape).

In a Magnetic Refrigeration System, a controlled magnetic field applies a series of Magnetization-Demagnetization cycles to the magneto-caloric alloys. Each of these cycles creates a temperature gradient in the material. A rapid succession of these cycles produces the final and stabilized hot and cold temperatures in the refrigerated system.

 

An environmentally friendly coolant fluid (glycol water) ensures the heat transfer between the cold and the hot sources. Similar to a heat pump process, Magnetic Cooling can be adapted to any kind of refrigeration system (professional fridge, display case, home appliance...).

 

Cooltech Applications is the only company in the world able to produce machines way above a few hundred Watts of Cooling. It has contributed key innovations to Magnetic Cooling, to allow economically viable high capacity systems: Weak magnetic field, Multi-stage, multi loop, rotating Architecture, Simple, blade-shaped Material, Simplified and optimized Hydraulics.

benefits FOR THE ENVIRONMENT

No Refrigerant Gas

The magnetic refrigeration system does not use any refrigerant gas and is not affected by the regulations challenging the use of refrigerants (F-gas, SNAP policy…). By 2030, refrigeration and air conditioning will account for about 13%  of the global greenhouse gas (GHG) emissions. Magnetic cooling will contribute to reducing this figure by producing cold without any polluting gas.

Energy saved

Energy savings up to 50%. Today, refrigeration and HVAC accounts for 17%  of the global electric consumption. It is time to change! Cooltech technology uses permanent magnets which do not require more energy source to produce the field. The system only needs a little motor and a pump to operate the system.

Environmental footprint

MCM use low footprint components and may be recycled.

BENEFITS FOR CUSTOMERS

Regulation Compliance

 

Thanks to a 0 GWP, our system is compliant with all past and future environmental regulations.

Low maintenance cost

 

Magnetic cooling requires a low level of maintenance (low rotational speed, low pressure, no leaks and no hazardous chemicals…) which lowers the operational cost for the end use.

Fast ROI

 

The energy savings allow  a quick return (depending on electricity costs).

Reduced Noise & Vibrations

 

The magnetic refrigeration system operates with a low noise level and reduced vibrations.

Endurance

 

Thanks to a low pressure system, the MRS ensures a better safety for end-users. The absence of refrigerant gas protects the users from hazardous leaks. Measurements were performed on all MRS types and results showed that the magnetic emissions that surrounded Cooltech’s devices at 10cm were far lower than the ones from a little fridge magnet souvenir.
