Low pressure showered evaporator in absorption cooling unit.

Author(s) : CURKA D., MOLOTTA M.

Summary

The article describes the subject of low pressure absorption cooling with the working pair fluids lithium bromide and water. It pursuits the design of heat exchangers in the unit and it targets on the influence of the type of the evaporator's construction on the output of the whole unit. In graphs are shown measured values on the small-scale experimental unit with a cooling power of 1 kW. The application of a showered heat exchanger in the evaporator of the cooling machine requires water circulation as the primary cooling medium. The primary cycle is powered by a circulation pump sucking water from the evaporator and showering the exchanger. The exchanger has on its inner side cooled medium of secondary circuit which on its outer side cools down ambient air. The article discusses mathematical model theoretical possibilities of designing primary circuit and its influence on total effectiveness of cooling unit. The results of these experiments serve as foundations for the design and construction of the experimental cooling unit with an output of 10 kW.
