     this paper examines the problem of achieving desuperheating through liquid injection in two-staged refrigeration systems based on screw compressors. the oil cooling process by refrigerant injection is also included. the basic thermodynamic principles of desuperheating and compressor cooling as well as short comparison with traditional method with a thermosyphon system have also been presented. finally, the collected data referring to a big refrigeration plant are analyzed in the paper. specific ammonia system concept applied in this refrigeration plant has demonstrated its advantages and disadvantages.
