Geothermal or Hydrothermal Heat Source Refrigeration Versus Electric Power and Fossil Fuel Sources for Process and Air Conditioning

Geothermal energy may have much value for service other than electric generation. It may serve to energize refrigeration systems directly. After a review of methods, a design is proposed for a cooling module that may be operated where geothermal heat is available to reduce power use. A New Zealand unit now works.
