Abstract
A system for cooling residential or commercial refrigerators, freezers, ULT freezers, and air conditioners is disclosed using liquified gas as the refrigerant. The system has no HCFCs or CFCs. The system is completely non-polluting and returns the refrigerant air to the environment in a cleaner state than the input air. The system is totally green, obtaining all energy from an array of solar panels and may be operated independently and remotely from all other energy sources. The refrigerant may be liquid air or liquid nitrogen. The system may also operate on-the-grid for power.
