Performance of absorption-type heat pump with mixture solution of lithium bromide and lithium nitrate

With the water-lithium bromide-lithium nitrate of mole ratio 4∶1 of lithium bromide to lithium nitrate as working pair, calculates and compares the performance with that of water-lithium bromide in single effect absorption-type heat pump. As a result, the coefficient of performance can be increased by 5% and anti-crystallization properties can be improved markedly by using the new solution.
