| 摘要 |
A cooling method and apparatus which uses an absorption cycle with ammonia as the refrigerant and in which a generator (31,34) converts a liquid ammonia solution into ammonia gas or vapour for supply to a condenser (36) in which the ammonia gas or vapour is condensed into a liquid ammonia solution. The liquid ammonia solution is supplied to an evaporator (39) in which liquid ammonia is evaporated into ammonia gas or vapour to thereby absorb heat and an absorber (43) absorbs the ammonia gas or vapour back into an ammonia solution. The evaporator (39) includes a reservoir or bulb (40) which retains portion of the liquid ammonia solution which is converted back into an ammonia gas or liquid by exposure to ambient heat and returned to the condenser (36) for recycling. |
