<p>In an absorption refrigeration system employing an inert gas, refrigerant vapor expelled from solution in a generator normally is conducted from the vapor space of the generator through a main vapor line to a condenser in which the vapor is liquefied and from which liquid refrigerant is conducted to an evaporator to produce useful refrigeration. Frost accumulating on the evaporator is melted by expelled vapor which is diverted from the main vapor line through a U-shaped liquid trap and flows directly to the evaporator when the liquid trap is empty.</p> |
