PERFORMANCE ANALYSIS OF A MAISOTSENKO CYCLE-BASED ENERGY-EFFICIENT EVAPORATIVE AIR CONDITIONER

This paper reviews the performance of a new evaporative cooling system based on the Maisotsenko Cycle (M-Cycle). More cooling and comfortable air conditioning are obtained using this new energy-efficient evaporative cooling technology. This technology can deliver cooling air temperatures lower than those obtained by either direct or indirect evaporative cooling systems, without increasing humidity. No water or humidity is added to the primary (or product) air-stream in the process. This approach takes advantage of the thermodynamic properties of air, and it applies both direct and indirect cooling technologies in an innovative cooling system that is drier than direct evaporative cooling and cooler than indirect cooling. The technology also uses much less energy than conventional vapor compression air-conditioning systems and therefore can be a cost- and energy-saving technology. Performance tests have shown that the efficiency of the evaporative cooler using M-Cycle is higher than that of conventional vapor compression cooling systems, while it provides the same amount of cooling. It is suitable for climates having low to average humidity.
