Abstract
A method of operating an adsorption refrigerator comprising two adsorption columns each housing therein a solid adsorbent and heat transfer tubes and sealed with a refrigerant, a condenser, an evaporator, paths for refrigerant connnecting the adsorption columns to the condenser and evaporator so that the refrigerant may be circulated through the columns, and a pipeline equipped with a valve connecting directly the adsorption columns, which method comprises changing over the adsorption columns periodically alternately between adsorption and desorption phases in manner that the one and the other adsorption columns are at opposite phases and that a heat transfer medium on a heat source side and a coolant are routed through alternately in response to desorption and adsorption phases, respectively. Shortly before one cycle of adsorption and desorption phases is terminated, the paths for refrigerant are shut off and the valve is opened, the adsorption and desorption phases are further advanced between the columns while continuing to supply the heat transfer medium and coolant, thereby to finish the cycle, and subesquently, the valve is closed to change over to a next cycle of just opposi…
