Abstract

Application technology of oil-free centrifugal chiller using R1234ze(E) refrigerant has been successfully developed in single/double compressor models. The chiller system design integrates domestic oil-free centrifugal compressor, flooded or spray-type evaporator, shell-and-tube condenser, flash tank economizer, and electric expansion valve to compose the high energy efficiency two-stage-compression refrigeration cycle. The chiller control system adopts domestic PLC controller to perform the high efficiency and reliable commercial operation. In addition, the remote IoT supervisory platform is capable of monitoring the real-time running status and intelligibly analyzing the power consumption of the chiller system.
