“…The gain-output-ratio (GOR) of the hybrid system was found to be higher than the conventional HDH system. Chiranjeevi and Srinivas [8] integrated a two-stage HDH system with a single-effect absorption refrigeration (VAR) plant, which was able to simultaneously produce freshwater and cooling effects at 670 LPH and 75 kW, respectively. Sadeghi et al [9] reported a multi-generation hybrid system combining a water-heated HDH cycle, an organic Rankine cycle, and an ejector refrigeration cycle.…”

“…Nevertheless, there are some clear differences between the DPC-WR system and other combined cooling and water recovery methods. It can be noticed that the EUF of the DPC-WR system is higher than that of the HDH-VAR method [12] but lower than that of the HDH-VC method [15] (Table 5). However, it is important to notice that in [15], only .…”

This paper presents the analytical investigation of a novel system for combined Dew Point Cooling and Water Recovery (DPC-WR system). The operating principle of the presented system is to utilize the dew point cooling phenomenon implemented in two stages in order to obtain both air cooling and water recovery. The system performance is described by different indicators, including the coefficient of performance (COP), gained output ratio (GOR), energy utilization factor (EUF), specific energy consumption (SEC) and specific daily water production (SDWP). The performance indicators are calculated for various climatic zones using a validated analytical model based on the convective heat transfer coefficient. By utilizing the dew point cooling phenomenon, it is possible to minimize the heat and electric energy consumption from external sources, which results in the COP and GOR values being an order of magnitude higher than for other cooling and water recovery technologies. The EUF value of the DPC-WR system ranges from 0.76 to 0.96, with an average of 0.90. The SEC value ranges from 0.5 to 2.0 kWh/m3 and the SDWP value ranges from 100 to 600 L/day/(kg/s). In addition, the DPC-WR system is modular, i.e., it can be multiplied as needed to achieve the required cooling or water recovery capacity.

“…Houa et al [12] used simulation method to verify the feasibility of marine cooling system with seawater cooling and seawater desalination. Chiranjeevi [13] studied the combination of the two-stage seawater desalination and refrigeration system to improve the energy utilization coefficient. Scholars have studied other methods for producing distilled water, for example, Rommerskirchen [14] produced distilled water by using the single module electrode capacitor.…”

A new machine to produce distilled water was provided, which includes a heat pump system and a vacuum system. And in the vacuum system of this new machine, the ejector is the key component. Three kinds of ejectors were studied by using FLUENT software to simulate their parameters. The simulation results showed that a vacuum is formed in the ejector throat, where the speed also reached its maximum value. The optimized ratio between the area of the throat and that of the mixing section can be obtained according to theoretical calculations. The ejector with the ratio 0.0156 can be used to prepare distilled water, and the experimental results show that the energy consumption of 1 kilogram distilled water is lower than 0.3 kWh. In the heat pump system, the capillary is the key component. Five kinds of capillaries were studied by using CFD software to simulate their parameters. The simulation results showed that the larger the degree of supercooling of the refrigerant in the capillary, the larger the liquid volume fraction of the outlet refrigerant. The experimental results show that suitable capillary can greatly improve the efficiency of the system.
