Résumé

An experimental investigation has been carried out to measure gas temperature transients in the suction chamber of a small reciprocating compressor operating at 3600 rpm. To this extent, two different measurement techniques, represented by a hot-wire system and a micro-thermocouple, were applied. Results for valve displacement and pressure pulsation in the suction chamber were also obtained to complement the analysis. Measurements indicated abrupt variations in all flow properties, strongly linked to the valve motion. It has also been observed a considerable increase in the gas temperature during the period in which the suction valve is closed, associated with high heat transfer rates between the gas and the suction chamber walls.
