Simple Mathematical Models of Mode Splitting of Hermetic Compressor Shells that Deviate from Axisymmetry

Predicting the Influence of Internal Mounting Bracket and External Mounting Feed Locations on Sound Radiated from Hermetic Compressor Shells

Random Vibration Fatigue Tests To Prove Integrity Of Cantilevered Attachments On Compressor Shells

Many Air Conditioning and Refrigeration hermetic compressor shells are designed with cantilevered attachments such as control valves. These attachments are subject to several sources of loading such as shell pressure, external tube load or vibration. One of the most common failure modes yet the least predictable is fatigue due to vibration at the joint with the shell. The purpose of the paper i...

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...

Chemistry of Pyrolysis and Kinetic Studies of Shea Nut (Vitellaria paradoxa) Shells Activated Carbon for Textile Waste Water Treatment

Phosphoric acid (H3PO4) and Zinc chloride (ZnCl2) catalyzed shea nut shells, subjected to a one way activation scheme was employed to study the adsorption kinetics and mode of diffusion of industrial dye uptake. Thermodynamics data obtained in this study indicate that the sorption of dye spontaneously increases with time and decreases after equilibration was...

Simulation and Development of Trans-critical CO2 Rolling Piston Compressor

Environmentally speaking, of assorted widely-used refrigeration systems, the trans-critical CO2 system is one of the potential competitors. In this research, a horizontal semi-hermetic rolling piston compressor is developed for trans-critical CO2 cycle. This paper also presents a series of mathematical simulation models to identify the main factors influencing compressor’s performance. Based up...
