Title:
HEAT TRANSFER METHOD & APPARATUS
Document Type and Number:
WIPO Patent Application WO/2013/007991
Kind Code:
A3
Abstract:
The present disclosure relates to heat transfer methods and apparatus. The method comprises evaporating a first working fluid in an evaporator in the presence of a second working fluid thereby absorbing heat from circulating water within the process, transporting a mixture of first working fluid and second working fluid to a condenser/absorber where a third working fluid is added and whereby the third working fluid dissolves the second working fluid from the first working fluid causing the first working fluid to condense and transmitting heat to a heat sink, transporting the first working fluid back to the evaporator, transporting the mixture of the second and third working fluids to a separator wherein separation of said second and third working fluids from one another takes place, transporting said second working fluid to the evaporator and transporting said third working fluid to the condenser/absorber. The separation of second and third working fluids may be assisted by injecting of a pressurised gas and use of desiccants. Apparatus to accomplish the method are also disclosed.
