“…n is the number of effective parameters that is determined according to previous researches. This value is 5 for CoFRMC type IEC [31][32][33][34][35], 6 for PCoFMC type IEC [36,37], and 10 for the DEH subsystem [2,8,15,16].…”

“…They showed that the numerical model predicts the prototype performance with ±10% deviation from the test results. Gao et al [8] experimentally investigated a liquid desiccant indirect evaporative cooling which its second part was the perforated counter flow M-Cycle, PCoFMC, indirect evaporative air cooler. They showed that the cooling capacity in the second stage is directly influenced by the variation of dehumidification capacity of the first stage, which is dependent upon the inlet parameters of the air or desiccant.…”

“…These types of IECs improve the performance of the cooling system by redirecting a portion of the cooled air (product air) to the working air channels. Like all previous published literatures regarding DEVAP system [2,7,8,13,15,16], in this survey the counter types of Mcycles (CoFRMC and PCoFMC) were considered and modeled as the second part of the DEVAP system. …”

“…In this regard, a comprehensive investigation on published literature was conducted to gather a complete collection of data required for modeling the DEVAP. For accurate and thorough evaluation of the DEVAP system, each stage should be evaluated separately; however, some studies reported the performance of the DEVAP system by considering it as an integrated system [2,8,16]. In another research [15], although the stages were evaluated separately, the obtained data set, due to insufficiency, do not ensure a high accurate model.…”

“…Dew point evaporative cooling is somewhat a configuration of indirect evaporative cooling comprising adjacent wet and dry air passages/channels. It consists of specially made plates that are designed to wick water evenly on side and transfer heat through the other side; there are numerous holes distributed in the air flow channels of the incoming working air [102,103] (Fig. 10).…”

Liquid desiccant cooling systems (LDCS) are energy efficient means of providing cooling, especially when powered by low-grade thermal sources. In this paper, the underlying principles of operation of desiccant cooling systems are examined, and the main components (dehumidifier, evaporative cooler and regenerator) of the LDCS are reviewed. The evaporative cooler can take the form of direct, indirect or semi-indirect. Relative to the direct type, the indirect type is generally less effective. Nonetheless, a certain variant of the indirect type -namely dew-point evaporative cooler -is found to be the most effective amongst all. The dehumidifier and the regenerator can be of the same type of equipment: packed tower and falling film are popular choices, especially when fitted with an internal heat exchanger. The energy requirement of the regenerator can be supplied from solar thermal collectors, of which a solar pond is an interesting option especially when a large scale or storage capability is desired.

The vapor compression air conditioning (VCAC) is the most widely used method for space cooling. However, it has some disadvantages, such as the fact that it consumes more electricity, depletes the ozone layer, and contributes to global warming. The liquid desiccant system using an evaporative cooler is a better replacement for a VCAC because it is cost-effective and environmentally sustainable. This paper initially introduces the fundamental principles of desiccant cooling and different types of liquid desiccant systems. Then, the desiccant systems using evaporative coolers are comprehensively reviewed. Finally, the assessment of system performances by different researcher's works is evaluated. It is observed from the review work that the liquid desiccant cooling system (LDCS) using an evaporative cooler could save energy consumption compared to VCAC. Highlights• Liquid desiccant dehumidifiers integrated with evaporative coolers are discussed.• LD dehumidifier integrated with evaporative cooler is an energy-efficient alternative in hot and humid areas.• DEVap system saves 2% to 3% of the annual energy.• The use of an LD dehumidifier in conjunction with an M-cycle IEC increases dehumidification.
