    • PROBLEM TO BE SOLVED: To supplement the lowering of a heat efficiency when a heat exchange is performed between an absorption side heat exchanger and a radiating side heat exchanger through an intermediate heat medium.
      SOLUTION: A coolant circulating route 3 is formed between a cooling unit 1 as the absorption side heat exchanger and an air-cooled condenser 2 as the radiating side heat exchanger, and the cooling unit 1 is connected to the air- cooled condenser 2 so as to be heat-exchanged. The heat medium for the cooling unit 1 is, for example, freon which is cooled by the coolant in the circulating route 3. The coolant is cooled by the air-cooled condenser 2. A circulation pump 4 and a one-way valve 5 as a coolant pressurizing means are disposed on the high temperature side of the circulating route 3, and a gas sealing valve 6 and a flow restricting valve 7 as a coolant depressuring means are disposed on the low temperature side. Also, a tank 8 for saturated gas balance is installed for the gas sealing valve 6. Extra gas for preventing a saturated concentration of gas from being varied even if a coolant temperature is varied slightly is accumulated in the tank 8.

    • 要解决的问题:为了补充当通过中间热介质在吸收侧热交换器和散热侧热交换器之间进行热交换时的热效率的降低。 解决方案:在作为吸收侧热交换器的冷却单元1和作为散热侧热交换器的风冷冷凝器2之间形成冷却剂循环路径3,并且冷却单元1连接到空气冷却冷凝器 2进行热交换。 用于冷却单元1的热介质是例如由循环路径3中的冷却剂冷却的氟利昂。冷却剂由空气冷却冷凝器2冷却。循环泵4和单向阀5作为 冷却剂加压装置设置在循环路径3的高温侧,并且在低温侧设置有作为冷却剂保持装置的气体密封阀6和限流阀7。 此外,为了气体密封阀6安装了用于饱和气体平衡的罐8.另外,即使冷却剂温度稍微变化,也可以防止气体饱和浓度变化的额外气体存储在罐8中。版权所有: (C)2004,JPO
