Effect of humidifier characteristics on performance of a small-scale humidification-dehumidification desalination system

Saddam Hussain Soomro et al.

Summary: This study investigates a laboratory-scale humidification-dehumidification (HDH) desalination system using different hydrophobic packing materials. The hackettes packing material showed the highest mass transfer coefficient and produced the highest productivity and gain output ratio. The results also showed that saddle packing performed better than snowflakes in the HDH process. The study also investigated the effects of operating parameters on the thermal performance of HDH systems with different packings.

A comprehensive review on humidifiers and dehumidifiers in solar and low-grade waste heat powered humidification-dehumidification desalination systems

Ravichandran Santosh et al.

Summary: The solar and waste heat-powered humidification-dehumidification (HDH) desalination systems are of increasing significance due to global warming and water scarcity. This study highlights the potential of various humidifiers and dehumidifiers in improving the efficiency of these systems. It found that the combination of cellulose humidifier and finned tube dehumidifier was effective in the HDH process. Waste heat-powered systems offer dual benefits of freshwater and improved cooling or electrical energy, while solar-powered systems only produce freshwater.

Experimental investigation of the influence of vapor compression refrigeration in a multistage reciprocating dehumidifier test rig

Sampath Suranjan Salins et al.

Summary: The study found that the dehumidification unit with vapor compression refrigeration performed better in terms of dehumidification efficiency, moisture removal rate, and mass transfer coefficient compared to the system without vapor compression refrigeration. However, the system with vapor compression refrigeration required slightly higher energy consumption, leading to a reduced system coefficient of performance.

Comparative performance analysis of a static & dynamic evaporative cooling pads for varied climatic conditions

Shiva Kumar et al.

Summary: The study introduces the development and performance testing of an evaporative cooling unit. Results show that the system's performance, including evaporation rate, cooling effect, coefficient of performance, and energy consumption, are affected by different input conditions. The experimental findings indicate that the system's performance decreases with increasing air flow rate, and the optimal performance is achieved at a water flow rate of 0.6 LPM; dynamic packing achieves thermal comfort faster compared to static packing.

Experimental and normalized sensitivity based numerical analyses of a novel humidifier-assisted highly efficient indirect evaporative cooler

Muhammad Ahmad Jamil et al.

Summary: The paper presents a novel humidifier-assisted regenerative indirect evaporative cooler that effectively mitigates fouling propensity and water management issues within the system, demonstrating good cooling performance in various operating scenarios. Sensitivity analysis shows the most influential parameters on cooler performance, with trends of primary air inlet temperature > primary air outlet temperature > primary air velocity for coefficient of performance, and secondary air outlet temperature > primary air inlet temperature > primary air humidity > primary air outlet for cooler effectiveness.

Research development of indirect evaporative cooling technology: An updated review

Hongxing Yang et al.

Summary: Driven by economic growth and demand for thermal comfort, energy consumption of air conditioning is increasing. Indirect evaporative cooling is an energy-efficient solution, but faces limitations like output temperature constraints and poor wettability on wet channel surfaces. Research progress shows potential for improvement through dew-point evaporative coolers and innovative wicks to enhance cooling performance.
