Patent ID: 7159407

Claim:
A compression cycle refrigeration system for controlling temperature, comprising: a chamber; a vacuum pump coupled to the chamber, the vacuum pump lowering pressure within the chamber; a supply of a liquid hydrogen-bonded refrigerant; an atomizer coupled between the supply and the chamber, the atomizer outputting micron-sized refrigerant droplets into the chamber, wherein the refrigerant droplets evaporate to form a gaseous refrigerant by absorbing heat from its surrounding; and another chamber coupled between the vacuum pump and the supply, said another chamber being a heat exchanger including a conduit carrying a medium into and out from the heat exchanger to absorb heat from the gaseous refrigerant; wherein the medium is an ambient air, the vacuum pump compresses the gaseous refrigerant into said another chamber, and the gaseous refrigerant condenses inside said another chamber to form the liquid hydrogen-bonded refrigerant by loosing heat to its surrounding and is returned to the supply.
