چکیده

Several different methods of measuring cylinder pressures generated during liquid slugging in Hermetic and Semi-Hermetic compressors have been devised. The methods are discussed and compared, and test results are presented. Some interesting aspects of liquid slugging are also discussed. An empirical relation for predicting maximum cylinder pressure aa a function of compressor power, bore size, and stroke length is presented.

The Detection of Liquid Slugging Phenomena in Reciprocating Compressors via Power Measurements

The presence of liquid refrigerant in the compressor cylinder during operation, or liquid slugging, is one of the most common causes of failure in reciprocating compressors. We propose to detect this fault by analyzing the electrical current flowing into the compressor and identifying the change in the load on the motor caused by the presence of liquid in the compressor cylinder. Two different ...

An Investigation of Compressor Slugging Problems

Mathematical models have been popularly applied to study the compression processes of superheated refrigerant vapor in compressors. As to the case when refrigerant enters a compressor cylinder in the state of liquid and vapor mixture, however, the availability of fundamental studies is very limited. -A mathematical model is presented to simulate the compression processes of two-phase saturated ...

Prediction of Slugging-Induced Cylinder Overpressures

In typical refrigerant compressors, peak cylind er pressures under liquid slugging conditions are as high as 10 times the peak pressures during the normal operation. In this paper we model this phenomenon by considering the compression process with a separated gas and liquid media in the cylinder. Two cases of this model for various liquid fractions are simulat ed. Even though time histories co...

Utilization of Volumetric Displacement in Reciprocating Compressors

The main factors affecting utilization of volumetric displacement of reciprocating compressors are analysed. A coherent system of parameters to quantify these is formulated. Reference is made to conventional parameters and to the work of other authors. Some new parameters are introduced and int~rrelationships are described. The overall_purpose of the theory is to apportion shortcomings in the v...

Comparison Of Hermetic Scroll And Reciprocating Compressors Operating Under Varying Refrigerant Charge And Load

An experimental rig has been built to test a horizontal scroll compressor and a reciprocating compressor of similar size and capacity. The compressors were tested with refrigerant.R404A operating at varying evaporator and condenser temperatures. The paper provides much needed information regarding the efficiency of the compressors operating under the same conditions with the same system paramet...
