“…In order to handle both sensible and latent cooling loads, the air is cooled below the dew point temperature, which implies a high energy consumption of the chiller. Some strategies have been examined to reduce the cooling load in traditional AHUs by improving the thermodynamic processes using energy recovery units [37,38] and evaporative coolers [39]. For instance, Yari et al [40] used air-to-air heat exchangers in an AHU with 100% fresh air and an AHU with return air and observed that the use of such devices was more effective in the case of 100% fresh air, where the cooling load was reduced by 32%.…”

“…Therefore, it is now more crucial to attempt to develop and use more efficient and environmentally friendly processes in air conditioning sector ever before. To reduce emissions from cooling processes and protect the ecosystem, high-energy efficiency "Green Cooling" technologies, which uses natural fluids such as water and air, should be widespread [2][3][4].…”

In this study, an innovative indirect evaporative cooler is presented and experimentally analysed. Although there are many evaporative cooler designs, this study proposes a unique Mcycle type evaporative cooler with newly designed heat exchanger to enhance the cooling performance of indirect evaporative coolers. The prototype was assembled for the experimental investigation of the system and tested in the laboratory environment under the conditions of constant air flow rate of 350 m 3 /h, circulating water temperatures of 15 °C and 20 °C, inlet air temperatures of 25 °C and 30 °C and lastly inlet air humidity of 9g/kg and 13g/kg, respectively. Based on the data obtained during the experiments, calculations were performed for the cooling capacity, cooling efficiency, energy efficiency and exergy efficiency of the system for each case. The findings showed that the highest wet bulb effectiveness, dew point effectiveness and EER of evaporative cooler were found to be 0.91, 0.62, and 0.77, respectively.

“…Evaporative cooling technologies have been subject to previous review articles. These provide a general approach (Amer et al, 2015; Okafor, 2017), sometimes focusing on one technology in particular (Pacak & Worek, 2021; H. Yang et al, 2021), or on research in a certain region (Xuan et al, 2012), their integration in buildings (Cuce & Riffat, 2016; Emdadi et al, 2019), a particular application (Misra & Ghosh, 2018; Odesola & Onyebuchi, 2009; Ulpiani, 2019), or the use of alternative materials (Emdadi et al, 2016; S. He et al, 2015; Kumar et al, 2020). The main factors influencing DEC operation (Tejero‐González & Franco‐Salas, 2021) and the possibilities of enhancing evaporative cooling (Y. Yang et al, 2019) have also been the target of existing reviews.…”

“…Indirect evaporative cooling (IEC) overcomes this issue by separately driving the airflow to be conditioned from a secondary airstream that is evaporatively cooled, sensibly cooling the former in an air-to-air heat exchanger. Duan et al (2012) and more recently H. Yang et al (2021) reviewed existing IEC technologies, which have developed rapidly over the last few decades. Particular attention is currently being paid to dew point indirect evaporative cooling (DPIEC) systems, which can ideally cool air down to dew point temperature (DPT) (Pacak & Worek, 2021).…”

Evaporative cooling has a major role to play in fighting climate change and in achieving a low‐carbon economy. As it helps to reduce energy demand for air conditioning, it is gaining attention in terms of improving energy efficiency in buildings. Evaporative cooling from wetted media can enhance water–air contact, thereby improving heat and mass transfer further and avoiding aerosols. Wetted media are commonly called evaporative cooling pads and are widely used in greenhouses, intensive livestock farming, and industrial facilities. However, a deep understanding of evaporative cooling pad performance can enhance their application to indoor occupied spaces such as residential or commercial cooling, or in hybrid air conditioning systems. Most studies analyze pad performance mainly in terms of pressure drop and saturation effectiveness. However, some studies propose alternative cooling efficiency parameters and others provide insights into key aspects such as power requirements and the coefficient of performance, water consumption, risk of water entrainment, material decay, and air quality, as well as the effect of water temperature and salinity, solar radiation, or wind speed. Existing results on these less studied performance issues are reviewed, and we identify the gaps in the literature in addition to highlighting the main challenges encountered, in an effort to guide future researchers in the field and enhance the application of direct evaporative cooling.
