“…The numerical simulation showed increase of power consumption with a fin height increment. Wan et al [54] prepared an analysis of counter-flow DPEC with two configurations (A: parallel and B: counter) of water film flow distribution referring to air stream. The two-dimensional computational fluid dynamics model was developed.…”

The indirect evaporative cooler (IEC) has excellent potential to replace or improve conventional vapor compression equipment in HVAC and refrigeration applications. This could be achieved by using the M-cycle (dew-point evaporative cooling technology). This thermodynamic concept makes it possible to derive a large amount of energy from the air stream (as latent heat released during water evaporation into the working air stream) and use it for another air stream (product). Its application has also spread to other sectors, such as water desalination and distillation, power plants, or NOx reduction. This paper provides an overview of the M-cycle mainly in air conditioning (MAC, D-MAC, H-MAC) and refrigeration (MCT, M-condenser). Various integrated solutions are described, showing improved effectiveness in terms of the wet-bulb temperature and the dew point. The design features of consolidated solutions are better In terms of the flow distribution, geometry, or volume. Most of the improvements confirm the great potential of the M-cycle to increase the unit or the system efficiency due to lower energy and water consumption.

“…They conducted numerical simulations which showed the increase of total power consumption with a fin height increment. Wan et al [22] analyzed counter-flow DPIEC considering water film parallel (configuration A) and counter (configuration B) flow distribution referring to the supply airflow. They developed a two-dimensional computational fluid dynamics model which was validated with experimental data.…”

Indirect evaporative cooling has the potential to significantly improve the natural environment. It follows from a significant reduction in electricity consumption in the hot period, and hence lower operating costs for cooling systems. This paper presents the current state of knowledge and research directions on dew point indirect evaporative cooling. It was found that researchers focus on the development of dew point indirect evaporative coolers (DPIEC) by improving its design, geometry, water distribution, and new porous materials implementation. To evaluate the performance of new types of DPIEC, different methods are used by the scientists. Finally, optimized devices are studied in terms of their performance in different systems, like hybrid and desiccant systems, considering different climate conditions. Potential directions of development of evaporative technologies were indicated, such as increasing the coefficient of performance of solid desiccant evaporative cooling systems, developing novel geometry, and efficient water distribution, including development of porous materials.

“…Other studies [23,24] were also carried out in which the key governing dimensionless numbers and correlations for the transient and steady-state characteristics were proposed. Wan et al [25] selected two DPCs with two different air flow configurations and compared cooling effectiveness and product temperature of both types. A thermodynamic analysis on a hybrid membrane liquid desiccant dehumidification and DPC was done in which the targeted supply air temperature of 20.0-28.0 °C with the humidity ratio less than 12.0 g/kg were reached [26].…”
