- Abstract
In the article a problem of performance improvement of the transport refrigerating system with eutectic plate evaporator is analysed. Due to weight limitations the system is equipped with single-stage compressor, which operates at very low evaporation temperatures. For such conditions the economizer technology offers substantial performance improvement. A transport refrigerating system with eutectic plate evaporator and economizer is investigated and compared to the eutectic system without economizer. Different configurations of an economizer system with additional suction liquid heat exchangers and with/without additional liquid injection through the discharge temperature control valve are analysed. Comparing to the initial system, the pull-down energy consumption decreased by more than 20% at 30°C ambient temperature. The proposed design of the economizer heat exchanger allows efficiency improvement without significant cost increase.
