Scientific research focus on improved refrigerants the global warming potential of which is lower than that of restricted R or R or more effective compressors; however, the high operational cost of maizotsenko units as well as its role in atmospheric pollution cannot maisotsenkl be limited. Both working pink lines and product red lines streams use dry channels Figure 1. However, this method leads to a significant increase of specific water consumption. Evaporation technology is simple and functional and has both residential and industrial applications, achieving significant efficiencies in suitable climates hot and dry.
There are two basic categories of EC: Using the experimental data, it is concluded that the specific water consumption tends to reduce as the ambient temperature increases due to a higher increase of the cooling capacity, varying between 2.

Riangvilaikul B, Kumar S. M-cycle has been designed to optimize the effectiveness of both stages of evaporation direct evaporation of working stream and heat exchange between streams.
Maisotsenko cycle M-cycle applies an improved design of indirect evaporative cooling. In reality, one layer of heat and mass exchanger HMX is show on Figure 4. The operation of the standard configuration of M-cycle is studied thereafter and useful conclusions are carried out, about the efficiency and the energy consumption electricity and water.
It was also important to understand the energy-saving potential of an EC, based on M-cycle.
As a conclusion, M-cycle can satisfy the cooling demand of most Greek cities and it is also expected to do at other Mediterranean regions of similar ambient cgclewithout consuming high amounts of electricity and water. The specific water consumption of the cooler under normal mode varies under common ambient conditions between 2.

Comparative study of the performance of the M-cycle counter-flow and cross-flow heat exchangers for indirect evaporative cooling. As the dangerous environmental effects of chlorofluorocarbons and greenhouse gases not only as direct emissions, but also as indirect emissions have been reduced, the interest is focused on environment-friendly cooling technologies. If the working stream flow is limited, the weakening of the evaporation so the temperature drop in the product stream is lower works as an obstacle to the cooling capacity, but not as much as a limited product stream flow does.
Evaporation in an IEC is caused 1 by the sensible heat of the working stream and 2 by the sensible heat of the product stream. Keeping the humidity ratio of product air constant, it succeeds in decreasing the air temperature down to ambient wet-bulb temperature and close to ambient dew-point dp temperature, by a smart heat and mass transfer procedure.
Numerical study of perforated indirect evaporative air cooler. The full terms of this license are available at https: Int J Heat Mass Transf. For this reason, the specific water consumption was defined, which is equal to the amount of water the evaporation of which can produce 1 kWh c. A heat exchange layer is used between the working airstream and the supply airstream, because the ambient wet-bulb wb temperature is theoretically the minimum achievable temperature of a conventional evaporative system.
ECs are based on water evaporation and latent heat utilization.
