ABSORPTION REFRIGERATING EQUIPMENT

Japanese Patent JP3182308

B2

PURPOSE: To provide an absorption refrigerating equipment of excellent coefficient of performance when viewed from the whole aspects of the equipment by improving the utilization factor of the outdoor air, and reducing a loss to defrosting operation.
CONSTITUTION: The condensing function and the evaporation function are switched with each other between a condensation/evaporation heat exchanger 11' and an evaporation/ condensation heat exchanger 14 by a piping connection switch 63B. The utilization factor of the outdoor air is improved because the condensation/heat radiation of the heat operating fluid 35a for cooling and the refrigerant is directly achieved by cooling with the outdoor air. In the first defrosting operation, the heat operating fluid 35a heated by opening/closing valves 301A, 301B, 301C, 301D is temporarily fed to an outdoor heat exchanger 61, and this heat is transferred to the evaporator 11' to achieve the defrosting. In the second defrosting operation, the condenser 11' is temporarily switched to the condenser, and the refrigerant vapor 7a is fed therein to achieve the defrosting. The heat operating fluid 35b for heating during the space heating operation is not extremely cooled, and the temperature of the indoor heat exchanger 62 is not dropped. This absorption refrigerating condition is capable of rapidly being shifted to the space heating operation after the defrosting is stopped, and the coefficient of performance viewed from the whole aspects of the equipment can be improved.
