“…As is well-known, in hydroponic greenhouses, it is very important to maintain suitable indoor environmental conditions to maximize the development of crops. The authors of [74], in a greenhouse in Poland for lettuce crops, designed a system to recover water from exhaust air. This water-recovery system exploits condensation in a crossflow heat exchanger operating within an air-conditioning system that maintains the required air parameters.…”

Agriculture is facing several very important challenges. Population growth means that more food must be produced to meet nutritional needs. However, this is putting excessive pressure on natural resources, such as water and land, which are heavily used for agricultural practices. For these reasons, we carried out a systematic review of existing studies in the scientific literature to better understand how innovative strategies can decrease water consumption in agriculture. It was performed following PRISMA guidelines, using the Scopus database to select papers that have investigated the link between water consumption and the main agriculture strategies, such as controlled-environment agriculture, hydroponics, and precision farming for field crops, in the last ten years. Data relating to the water requirements of the selected crops were estimated to provide a framework for evaluating possible solutions. The results showed that these innovative strategies have the potential to decrease water consumption, but more research is needed to fully understand their effectiveness and potential trade-offs. Therefore, both exogenous and endogenous crop factors should be considered to maximize water savings. The results will form the basis for a framework for assessing the sustainability of agricultural strategies and how they can be applied in a real-life case study.

The water crisis is currently affecting billions of people. To mitigate the issue, unconventional water sources should be taken into account. Among them, atmosphere is a promising possibility, but it is still considered a novel source, and more studies, based on real results concerning the behaviour of the Atmospheric/Air-to Water Generator (AWG) systems, also known as Atmospheric Water Harvesting (AWH) systems, are needed to prove the water extraction sustainability. The current research work describes the real application of an integrated AWG system, based on a thermodynamic reverse cycle, designed to extract water from air and take advantage of the other useful effects of the cycle at the same time. The integrated machine was placed in Dubai, in a worker village, and tested. The machine is able to provide, at the same time, with the same energy consumption, water, heating and cooling energy. On the basis of onsite measurements, calculations about the efficiencies, using the Water Energy Transformation (WET), plastic savings, due to bottled water avoidance, and economic sustainability were carried out. The work answers to research questions concerning the potentiality of integrated systems in Heating Ventilation Air Conditioning (HVAC) plants revamping, the economic sustainability of water extraction from air and the lack of tests on real AWG machines of thousand-litre production capability (large size).

“…The results are presented in Table 4. The outdoor air parameters t 1i = 30 • C and RH 1i = 45% are assumed to be representative for temperate European climate conditions [22]. Regarding these parameters, the temperature obtained by DPIEC 1, DPIEC 2, and DPIEC 3 is 20.8, 19.0, and 19.7 • C, respectively.…”

In this study, a multi-stage regenerative-cross-flow dew-point evaporative cooler performance is analyzed and compared to the performance of a regenerative dew-point evaporative cooler. The most beneficial configuration of the proposed exchanger was established on the basis of its geometry and performance analysis using validated numerical models. For specific outlet air parameters, it was found that the multi-stage cooler with a working-to-primary air-flow ratio equal to 0.3 reaches 5.6% lower outlet air temperatures and 10.2% higher cooling capacity when compared to the regenerative unit. The proposed cooler provides lower outlet air temperatures for all average outdoor air parameters in selected locations, for both dry and humid outdoor air parameters (e.g., Denver (USA) and Izmir (Turkey)).
