Keeping the humidity ratio of product air constant, maisotsenoo 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.

Maisotsenko cycle M-cycle applies an improved design of indirect evaporative cooling. An M-cycle—based cooled is structured by 40 heat and mass exchanging layers, creating the following apparatus Figure 5. In this paper, a cooler utilizing the M-cycle is analyzed; the aim was the production of dry and cool air with low electricity consumption only a simple axial fan of W consumes electricity and improvements maisotsrnko the cooler characteristics efficiency and water consumption.

Int J Heat Mass Transf. Published 6 March Volume In reality, one layer of heat and mass exchanger HMX is show on Figure 4.

Although ECs cannot achieve as low temperature as their users want due to the dew-point temperature restrictionM-cycle is the most effective IEC, the product air of which tends to the outlet air temperature of conventional building air-conditioning systems. And, as it is a quite new technology about 8 yearsits improvement potential in terms of electricity consumption is not negligible.

Maisotsenko open cycle used for gas turbine power generation.

Finally, the energy-saving potential is estimated in conventional cooling systems, in terms of electricity and capital cost, in order to evaluate the financial benefit of M-cycle application: 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.

The increased amount of heat inserted in the cooler, when the ambient air is hotter, reinforces the evaporation phenomenon, as already mentioned, resulting in higher temperature drops through the cooler.

So, if we aim to minimize water consumption, the lowering of the working stream mass flow is the best solution the cooler consumes less than 1. 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 maisotsenmo operational cost of these units as well as its role in atmospheric pollution cannot significantly be limited.


An experimental study of novel dew-point evaporative cooling system. The heat and mass exchanger is analyzed and described in detail, so the specifications of M-cycle will be clear and understandable. Int J Energy Clean Environ. Thus, the payback period of an EC, compared to a conventional one, is about 2.

Comparative study of the performance of the M-cycle counter-flow and cross-flow heat exchangers for indirect evaporative cooling. This cycle is an indirect evaporative cooling—based cycle, which utilizes a smart geometrical configuration for the air distribution.

Anisimov S, Pandelidis D. This work is published and licensed by Dove Medical Press Limited. A typical direct EC DEC consists of a box with voluminous humidification blocks, a water pump, and a water distribution system.

There are two basic categories of EC: As the working stream passes through the wet channels, the water is evaporated and the required latent heat is absorbed by the dry channel, which becomes cooler and cooler Figure 3. Several features of this site will not function whilst javascript is disabled. The hotwire was placed in the center of each air duct, so as to measure the maximum velocity.

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 cyclw limited product stream flow does. Thermodynamic performance assessment of a novel air cooling cycle.
