We study the refrigerant system for submersible electric pumps. This study aims to improve the existing cooling system of these electric pumps when they work partially or totally not immersed in the service fluid. Note that inefficient cooling systems cannot prevent the rise in temperature of the electric engine, and the consequent breaking of the electric pump. We propose a preliminary study of this system, where a two-dimensional model is used to describe the heat transfer among the engine of the electric pump, the refrigerant system and the external environment. This model is discretized by an explicit finite difference scheme, and the resulting algorithm has been implemented in MATLAB. We show some preliminary results obtained by this code, and the com- parison of these results with experimental data.

Abstract

We study the refrigerant system for submersible electric pumps. This study aims to improve the existing cooling system of these electric pumps when they work partially or totally not immersed in the service fluid. Note that inefficient cooling systems cannot prevent the rise in temperature of the electric engine, and the consequent breaking of the electric pump. We propose a preliminary study of this system, where a two-dimensional model is used to describe the heat transfer among the engine of the electric pump, the refrigerant system and the external environment. This model is discretized by an explicit finite difference scheme, and the resulting algorithm has been implemented in MATLAB. We show some preliminary results obtained by this code, and the com- parison of these results with experimental data.
