A study of reciprocating compressor finger valve dynamics
… from an Ingersoll Rand model 242 two-stage air compressor. Proximity probes were used to measure the valve position at two points on the exhaust valve at two different exhaust valve stop heights and at two points on the intake valve at one intake valve stop height in the lower exhaust valve stop …

Dynamic finite element modeling and analysis of a hermetic reciprocating compressor
… element modeling and analysis of a refrigeration compressor was investigated as part of a noise emission study. Natural frequencies and normal mode shapes were calculated for the major structural components of the compressor. The components were later combined to form a model of the compressor …

Shaking and Balance of a Convertible One- and Two-Cylinder Reciprocating Compressor
… the study of a one- and two-cylinder convertible reciprocating Freon compressor for air conditioning or refrigeration purposes. The main concern is the reduction of the vibration (noise) caused during the operation of the compressor. Vibration is a main concern when the compressor is shifted from …

Reciprocating compressor lubrication – lubricant dilution with natural gas species and the impact on lubrication rates at various operating conditions
Reciprocating compressors are ubiquitous in the natural gas industry as they provide much of the pressure necessary to move natural gas from the wellhead to the customer. Many of these compressors use lubricants to reduce friction and wear at the piston-cylinder interface. These lubricants have a …

A method for the spatial dynamic simulation of reciprocating compressors using the digital computer
… techniques to the dynamic analysis of reciprocating compressor designs. The analysis process is detailed in three steps. The first step, an interactive pre-processor, develops the shaking forces and torques acting on the machine. The second step is a batch processed program that …

Computer simulation of the steady-state thermodynamic processes and piston ring wear for a multi-stage intercooled reciprocating air compressor
… behavior of a multi-stage intercooled reciprocating compressor and its progressive loss of performance due to leakage. A theoretical model is developed to simulate the thermodynamics of the compressor system and the lubricating condition and wear of the piston ring pack for a …

Fault detection methods for vapor-compression air conditioners using electrical measurements
… rather than vapor, enters the cylinder of a reciprocating compressor during operation. Since the higher cylinder pressures that result can cause substantial damage and are difficult to measure directly, a method for detecting this fault is proposed that only uses observations of the …

Computer simulation of the Bristol compressor suspension system dynamics
… of the suspension system of a two-cylinder reciprocating compressor. A theoretical model is developed to describe the various steps undertaken to calculate the response of this six-degree-of-freedom rigid system. The response, which is in the form of a displacement vector, serves as the …

Testing and modeling of compressors for low-lift cooling applications
… thesis, an inverter-driven variable speed scroll compressor is tested on a de-superheater test stand to determine its performance in areas of low-lift and low compressor speed. The goal is to adapt this test stand so that it could be used to test a reciprocating compressor in this region. A …

Modelling the performance and dynamics of vapour compression refrigeration systems
… of liquid chillers. Mathematical models of the reciprocating compressor, expansion valve, evaporator and condenser are presented. The models are integrated to form the overall system model by passing conditions from one component to another. A series of steady-state and transient experimental …

Finite element modeling of a refrigeration compressor for noise prediction applications
… of a finite element model of a hermetic reciprocating compressor for noise prediction applications. Inherent difficulties in developing the finite element model of a complicated structure are discussed and appropriate modeling strategies are evolved. The development of the complete …

Experimental investigation of mist flow generated by reed valves in compressor discharge
… discharge of air conditioning and refrigeration compressors. It was identified that in a vast majority of compressors the discharge port is the gateway for the oil to leave the compressor and get carried over to the other components of the system. Between the discharge port and the discharge …
