In a lithium bromide absorption system, what is the lowest possible temperature that can leave the evaporator?

In a lithium bromide absorption system, the temperature leaving the evaporator is closely tied to the refrigerant properties and the overall effectiveness of the system. The absorption cycle uses water as the refrigerant, which evaporates in the evaporator to absorb heat from the surroundings.

The typical minimum temperature that can be achieved in the evaporator is influenced by both the refrigerant properties and the system's operational conditions. Water, as a refrigerant in this context, cannot evaporate below its freezing point without risk of freezing. Therefore, for practical applications in a lithium bromide absorption system, the evaporator typically operates around or above a temperature of 38 F due to these limits.

Operating below this range can lead to inefficiencies or potential operational issues due to freezing or improper heat exchange. Consequently, 38 F is recognized as the lowest effective temperature that can efficiently leave the evaporator without compromising the system's operational integrity.
