“…In literature and worldwide market, numerous arrangements and designing of evaporative cooling systems are available. However, upcoming three headings are important from the subject of thermodynamic conception, that is, isenthalpic cooling [46,47], sensible cooling, and dew-point (or below wet-bulb) cooling [10,48,49]. In order to highlight the significance of temporal and spatial variations on AC performance, 24 h-based ambient air conditions of two cities, that is, Multan (Pakistan) and Fukuoka (Japan), are investigated for nonhuman AC applications.…”

“…The Maisotsenko cycle (M-Cycle) evaporative cooling (MEC) is an advance thermodynamic conception of IEC by which the product air can be cooled to the ambient air dew-point temperature [10]. The fundamental scheme of MEC operation is presented by Figure 9(a), whereas details can be found from reference [10].…”

“…The fundamental scheme of MEC operation is presented by Figure 9(a), whereas details can be found from reference [10]. The MEC apparatus (dry and wet channels in Figure 9(a)) exploits the psychrometric renewable energy (available from the latent heat of water vaporization) in such a way that product air can be cooled to the ambient air dew-point.…”

“…On the other hand, the AC term is mostly associated with humans' thermal comfort as far as conventional literature and primary objectives are concerned [8,9]. Therefore, lots of AC technologies have been established for humans' thermal comfort and are under practice in order to obtain typical conditions of T a and RH, particularly for summer and winter seasons [1,10]. Out of them, most popular and highly efficient systems are based on electric-driven compressors.…”

“…Out of them, most popular and highly efficient systems are based on electric-driven compressors. Although compressor-based AC systems achieve desired T a and RH conditions efficiently, these are thermodynamically inefficient and consume huge amount of primary energy [1,10]. Moreover, these systems are based on environmentally harmful technologies and consume hydro-fluorocarbons (HFCs)/chlorofluoro-carbons (CFCs)/hydrochlorofluoro-carbons (HCFCs).…”

In addition to humans' thermal comfort, air-conditioning (AC) could be required for various nonhuman applications, for example, animals' AC, greenhouse AC, food storage and transportation, industrial processes, and so on. In this regard, optimum conditions of air temperature and humidity are explored and compared on psychrometric charts. Thermodynamic limitations of existing AC systems are discussed from the subject point of view. Consequently, four kinds of low-cost energy-efficient AC systems, namely: (i) direct evaporative cooling (DEC), (ii) indirect evaporative cooling (IEC), (iii) Maisotsenko cycle (M-Cycle) evaporative cooling (MEC), and (iv) desiccant AC (DAC), are investigated for climatic conditions of two cities, that is, Multan (Pakistan) and Fukuoka (Japan). In addition, systems' fundamentals and principles are explained by means of schematic diagrams and basic heat/mass transfer relationships. According to the results, performance of all systems is influenced by ambient air conditions; therefore, a particular AC system cannot provide optimum AC for all nonhuman applications. However, one or other AC system can successfully provide desired conditions of temperature and relative humidity. It has been concluded that evaporative cooling systems provide low-cost AC for dry climates, whereas DAC system is found energy efficient and viable for humid climates.

Metal–organic frameworks (MOFs) are superior sorbents for water adsorption‐based applications. The unique step‐like water isotherm at a MOF‐specific relative pressure allows easy loading and regeneration over a small range of temperature and pressure conditions. With good hydrothermal stability and cyclic durability, it stands out over classical sorbents used in applications for humidity control, water harvesting, and adsorption‐based heating and cooling. These are easily regenerated at moderate temperatures using “waste” heat or solar heating. The isotherm thermodynamics and adsorption mechanisms are described, and the presence of MOFs in the water–air system is explained. Based on six selection criteria ≈40 reported MOFs and one COF are identified for potential application. Trends and approaches in further synthesis optimization and production scale‐up are highlighted. No‐MOF‐fits‐all, each MOF has its own specific step location matching only with a certain application type. Most applications are technically feasible and demonstrated on the bench‐scale or small pilot. Their maturity is benchmarked by their technology readiness level. Retrofitting existing applications with MOFs replacing classical desiccants may lead to rapid demonstration. Studies on techno‐economic analysis and life cycle analysis are required for a rational evaluation of the feasibility of promising applications.

Advanced combined cycles using gas turbine and bottoming cycles have been developed to improve energy efficiency and output power of the conventional thermal power plants. In this study, integrated biomass gasification‐cascaded humidification advanced turbine and steam turbine cycle have been presented as a novel approach to reach out the sustainable energy vision. All generators of this comprehensive system operate by syngas produced from biomass gasification. Based on the technical consideration, modeling and simulation of the mentioned cycle have been performed, which results indicated more than 33.6 MW power generation and about 56.4% total efficiency in the base case. Moreover, parametric studies demonstrated the considerable dependency of the delivered power, specific fuel consumption, and heat rate to ambient temperature variations. In addition, principal parameters changes due to the fluctuation of the gasification temperature demonstrated an obvious increase in fuel consumption rate after crossing a turning point. Eventually, other achievements such as the negative effect of biomass moisture increase on cycle outputs, and also, advantages of turbine inlet temperature rise have obtained by plant analyzes. © 2019 American Institute of Chemical Engineers Environ Prog, 38:e13146, 2019
