Fast Response Temperature Measurements in a Reciprocating Compressor
Mathematical modeling of the dynamic processes in a compressor involves a knowledge of the various forms of energy exchange occurring in the system. Heat transfer to and from the gas is one such. Any detailed modeling of the heat transfer process would require a detailed knowledge of the temperature variations resolved to temporal scales at least as fine as the finest generated by the dynamics ...
متن کاملElectrical Determination of Reciprocating Compressor Instantaneous Angular Speed
HVAC compressor units are major energy consumers in both residential and commercial buildings today. Faulty and energy wasting operation of these units often goes unnoticed due to the corrective action of feedback control. Power system monitoring is an exciting approach for creating inexpensive, highly capable methods to monitor compressor unit performance. In this paper we develop a method to ...
متن کاملAn Integrated Approach to Reciprocating Compressor Design
A typical reciprocating co~pressor consists of a motor, a pump, suction discharge system and a lubrication system. An integrated computer simulation model incorporating all these components simultaneously was developed to predict, evaluate and optimize the overall performance and reliability. For the given design variants of a compressor, the computer program first calculates the mass flow rate...
متن کاملPerformance Prediction of Reciprocating Compressor
The technique of the modeling and analysis procedures of reciprocating compressor is described which predict the basic performance of the compressor, compute the pressure pulsations in cylinder and suction line and simulate valve motions. The polytropic process assumption was used for modeling cylinder thermodynamic process and four-pole transfer matrix for gas pulsations and spring-mass model ...
متن کاملThermal 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...
