Summary

Application of ejector systems for utilisation of low temperature heat and transform this heat for usable cooling power is one of the most effective and economic way for energy management. The basic concept of the hybrid system is to use a gas ejector in a vapor mechanical compression refrigeration system. The hybrid system is used for chilled water production required by air cooler in AC unit. The proposed system uses a gas ejector as the main device for compression of refrigerant during the period with relatively low condensing temperature, while for the period with high condensing temperature the compression of the refrigerant is provided by mechanical compressor. In effect the cooling power is produced with maximum use of low-temperature heat, such as a district heating system, solar power or waste heat. In the paper the operation of hybrid system in ejector mode and compression mode will be shown. The critical temperature that swich the modes in the hybrid system will be determined. The performance lines will be presented and discussed.
