Abstract

Numerical processing of the eroding thermocouple signals related to heat transfer analysis in the reciprocating compressor S. Jedrzejowski Institute of Heat Technology, TecWca/ [/M/ve^/Yy q/2odz, 90-924 lodz Email: sjedrzej@ck-sg.p. Iodz.pl Abstract The purpose of this paper is to present applications of the^NANMAC eroding- type thermocouples to record temperature histories of the surfaces, which take part in the heat exchange during the compression cycle. These thermocouples have a very small heat capacity and a short time constant. Additionally, similar measurements were taken using a thin film metal resistor. The experimental stand is equipped with a single cycle reciprocating compressor - especially adopted for the purpose of this work. The thermal conditions of the compression process in the compressor are well defined. This enables to repeat exactly experiments and comparing measurement methods. The paper presents measurement results of the surface temp
