Experimental investigation of torque measurement in hermetic compressor

Performance Evaluation of Hermetic Refrigeration Compressor Using Torque Measurement Method

A load stand has been built and used to det ermine the performance of an open type reciprocating r efrigeration compressor over a range of speeds. The load stand and instrumentation are desc ribed and sample test readings are given. Measured perform ance characteristics for the compressor over a range of speeds are p resented. Aspects of the load stand are discussed and conclusion s are drawn f...

Experimental Testing of Oil-Flooded Hermetic Scroll Compressor

In this work, a residential air conditioning compressor designed for vapor injection has been modified in order to inject large quantities of oil into the working chamber in order to approach an isothermal compression process. For a range of different oil injection scenarios, the result is a monotonic decrease in compressor discharge temperature as the oil injection rate is increased. In additi...

Thermal Analysis of a Hermetic Reciprocating Compressor

The development of more efficient hermetic compressors for refrigeration involves a sound analysis of the heat exchanges inside the machine to evaluate the interaction among compressor structure, flow characteristics, refrigerant properties and operative conditions. This work presents a computational procedure for the steady-state thermal analysis of a hermetic reciprocating compressor. The mac...

Parametric Study of Hermetic Reciprocating Compressor

A numerical simulation of the thermal and fluid-dynamic behaviour of hermetic reciprocating compressors has been developed by solving the one-dimensional and transient governing equations of the flow (continuity, momentum and energy) in the whole compressor domain. The governing equations are discretized using an implicit control-volume formulation. A SIMPLE-like algorithm, extended to compress...
