Abstract
The present paper is concerned with theoretical and experimental study and development of effective suction gas heat exchanger for hermetically sealed compressor. A single tube counter flow heat exchanger had been used, where water itself had been taken as a coolant. Energy consumption parameters as well as COP values have been obtained analytically for both the cases. Energy consumption parameter is 12% less as an average for a heat exchanger attached system compared to the system with out heat exchanger in a time span of 90 minutes. COP values obtained with heat exchanger are firmly better than that of the values with out Heat exchanger. COP values observed to be 7% higher for a heat exchanger coupled system compared to the system with out heat exchanger in the same time span of 90 minutes. In the present scenario where systems optimization is a necessity the present work would be useful in developing a energy efficient system with few modifications. This work would be useful to tackle the heat transfer related issues present in many gas compressors used in pumping and process industries.
Highlights
The compressor is one of the main parts of an air conditioner; it is the first component of the refrigerator to be modeled
Compressor would consume less work when its inlet temperature is low. This is because when the inlet temperature is reduced suction path gas superheating losses are reduced
It is observed that performance with a heat exchanger is always above than the performance with out a heat exchanger
Summary
The compressor is one of the main parts of an air conditioner; it is the first component of the refrigerator to be modeled. Compressor would consume less work when its inlet temperature is low. This is because when the inlet temperature is reduced suction path gas superheating losses are reduced. The need for rational energy consumption is a worldwide concern and the quest for reducing energy wasting comprises an optimization of energy use and how to lower consumption. These goals must be achieved without compromising comfort and other advantages brought by the use of energy, and without affecting efficiency and quality of installations
