Characteristics of a gas-liquid separator with a partial condenser in the absorption refrigeration cycle for automotive air conditioning

Abstract

transfer distance and to decrease the start-up time. However, the flow paths of the plate generator were not large enough to separate the refrigerant vapor from the two-phase flow. Therefore, a gas-liquid separator was also introduced. Commonly used working fluids in absorption refrigeration systems include ammonia as the refrigerant with water as the absorbent and water as the refrigerant with LiBr as the absorbent. The primary drawback of the ammonia-water pair is that ammonia is toxic, and systems that use it are regulated under the High Pressure Gas Safety Act. The primary drawback of the water-LiBr pair is that systems using it are unable to work at temperatures below zero degrees Celsius. As the working conditions of air conditioners in vehicles are more severe than those in residential use, 2,2,2-
