Compressors test life bench under wet compression conditions

Abstract

It is intend to design, control, build and set up, an essay for testing the compressors life when operating in wet compression condition. The purpose of this “bench”, is to determine the consequences of a biphasic refrigerant inlet, in terms of the rotary compressor reliability, as manufactures recommend to avoid these use. Therefore, it will be necessary to build a “test bench” that allows the test of different compressors models in a reduced compression-expansion cycle. The “bench” should permit the selection and the constant maintenance of the input conditions of the refrigerant (pressure, temperature, quality) the input condition of the refrigerant in terms of pressure, temperature and steam quality for different refrigerants. The refrigerants taken into consideration when computing the calculus are: R22, R134a, R410a, and R407c. The operation of this “bench” shall be governed by a system of controls to access and independently parameterize several test stations, although only one will be developed during the project
