Can we achieve (-) 100 0C with refrigeration system?

Yes, it is possible with Pascal Air refrigeration system

“PascalAir” is a refrigeration system using the ultimate natural working fluid, air. The system is an open type system circulating air directly in a cold storage as working fluids. It compresses air, removes the compression heat, and expands the air adiabatically to cool in a cold storage using air.

Using the ultra-low temperature air directly in a cold storage as working fluids, the system generates an ultra low temperature compressing, heating, and expanding air after cooling.

Energy Saving 34% reduction as compared to conventional refrigeration system.

Some plus points –

1. There is no need to provide an air cooler in the cold storage.
2. No heat load of fans and no heat exchange loss
3. Frost from moisture in the air can be treated in the cooling system.
4. Notification application for installation is not required since this system is exempt from the High Pressure Gas Safety Act.
5. No need for recovering and recharging refrigerant
6. It is possible to renew the cold storage while operating the existing cold storage.

Application –

1. Ultra-low temperature cold storage for bonito/tuna
2. Food rapid freezing system
3. Vacuum Freeze-dry
4. Chemical process cooling after chemical reactions
5. Medical care/product cooling
6. Manufacturing process for semiconductors Cryogenic crushing etc
