PERFORMANCE SIMULATIONS OF TWIN-SCREW COMPRESSORS WITH ECONOMIZER.
Author(s) : JONSSON S.
Type of article: Article, IJR article
Summary
IN A COMPRESSOR REFRIGERATION PLANT WITH AN ECONOMIZER, THE REGULAR EXPANSION VALVE IS REPLACED BY TWO VALVES AND AN INTERMEDIATE PRESSURE VESSEL. THE REFRIGERANT WHICH IS VAPORIZED AFTER THE FIRST VALVE IS INJECTED VIA THE COMPRESSOR ECONOMIZER INLET, IN GAS UNDER COMPRESSION, AT AN INTERMEDIARY PRESSURE AND UNDER COMPRESSION. THE ECONOMIZER ARRANGEMENT INCREASES THE REFRIGERATION CAPACITY AND IMPROVES THE COEFFICIENT OF PERFORMANCE (COP). IN THIS PAPER, A PERFORMANCE SIMULATION COMPUTER PROGRAM FOR TWIN-SCREW COMPRESSORS WITH AN ECONOMIZER ARRANGEMENT IS PRESENTED. COMPARISONS OF ECONOMIZER PERFORMANCE FOR DIFFERENT ARRANGEMENTS ARE POSSIBLE WITH THE SIMULATION PROGRAM. AN EXAMPLE IS GIVEN.
