  • Cooling with refrigerant feedback
    Patent number: 8132418
    Abstract: Disclosed herein is a method and apparatus for cooling an environment using a low temperature heat source. A cooling apparatus is provided. A refrigerant is vaporized from a refrigeration solution using the low temperature heat source. The vaporized refrigerant with part of the refrigeration solution is channeled to a separator. The vaporized refrigerant is separated from the channeled refrigeration solution. The refrigerant is further vaporized from the separated refrigeration solution leaving behind a dilute refrigeration solution. The refrigerant is condensed. A part of the condensed refrigerant is fed to the first vaporizer leaving behind a residual part of the condensed refrigerant. The residual part of the condensed refrigerant is evaporated by absorbing heat from the environment thereby cooling the environment. The evaporated refrigerant is absorbed by the dilute refrigeration solution to produce a concentrated refrigeration solution.
