EVALUATING COOLERADO CORPORTION'S HEATâ€MASS EXCHANGER PERFORMANCE THROUGH EXPERIMENTAL ANALYSIS
ABSTRACT
The innovative thermodynamic cycle known as the Maisotsenko cycle has provided a foundation from which many energy-efficient technologies have emerged in recent years. One of these technologies utilizes the benefits of indirect evaporative cooling to design, manufacture, and sell high-efficiency air conditioning systems around the world. At the core of these air conditioning systems is the heat-mass exchanger, which is capable of producing unprecedented air temperature reductions while also satisfying critical air flow-rate requirements. In an attempt to better understand the fundamental physics occurring inside the heat-mass exchanger, an experiment is conducted to measure internal pressures and temperatures for a chosen set of complementary product and exhaust channels. This is done by dividing each set of channels into a two-dimensional grid and collecting measurements at each node location. Once this data is obtained, it is processed and analyzed to evaluate performance based on three critical parameters: heat transfer, mass flow, and evaporation. Each of these parameters are then averaged based on the grid resolution and presented according to their x−y location within the heat-mass exchanger. A corresponding psychrometric analysis is then performed relative to the same two-dimensional grid, which provides a complementary perspective into the cooling process. Test results reveal a practical understanding of functionality and identify areas of improvement while recognizing the benefits of future design optimization.
