AN APPARATUS AND METHOD FOR PREVENTING THE CRYSTALLIZATION OF A SOLUTION IN ABSORPTION TYPE COOLER AND HEATER

PURPOSE: An anti-crystallization device of an absorption hot and cold water dispenser and a method for preventing a solution from becoming crystallized are provided to improve system performance while an anti-crystallization valve is opened so that the solution is not crystallized. CONSTITUTION: An anti-crystallization device of an absorption hot and cold water dispenser comprises a high temperature generator(10), a low temperature generator(20), a condenser(30), an evaporator(40), a absorber(50), and a solution line(101). The low temperature generator heats a middle concentration absorption solution using evaporating refrigerants. The low temperature generator generates a high concentration absorption solution by evaporating the refrigerants included in the middle concentration absorption solution. The absorber lowers the concentration of the evaporating refrigerants by absorbing the evaporating refrigerants into a high temperature absorption solution generated from the lower temperature generator. The solution line is connected to a line for the high concentration absorption solution in order to prevent the crystallization by mixing the high concentration absorption solution with the middle concentration absorption solution. An anti- crystallization valve(100) is installed in the solution line.
