This paper experimentally studies the mass transfer during the dehumidification/regeneration operation using the hygroscopic material calcium chloride and calcium chloride dehydrate as desiccant. These desiccants are compared on the basis of the same operation conditions. According to the analysis of heat and mass transfer processes, the key influencing factors are relative humidity and regener...

In liquid desiccant systems, an operating strategy of mixing small fractions weak and strong solutions integrated with a closed-loop has drawn attention for its ability to improve the system energy performance. This study proposed passive heat-pump-driven liquid-desiccant (HPLD) air-conditioning experimentally analysed performances. Based on density difference between solution in absorber sump ...

Globally, multiple efforts are being made to develop active atmospheric water generation (AWG) or extraction (AWE) systems, particularly using direct air-cooling technology produce from ambient air. However, this legacy technique is highly energy-intensive; it can only be operated when the local dew point above freezing of water, and does not scale create enough offer solutions for most industr...

Effective sub-gingival debridement is crucial to prevent serious systemic infections in hospitalized patients. Lack of compliance and the impracticality of repeated treatment in a short span of time are identified barriers to the performance of full mouth scaling and root planing (SRP). The aim of this randomized study was to evaluate the clinical and microbiological effects of the adjunctive a...

The aim of this study is to analyze the operating energy savings of a liquid desiccant and an indirect and direct evaporative cooling-assisted 100% outdoor air system (LD-IDECOAS) for marine applications. The LD-IDECOAS comprises a liquid desiccant (LD) unit and indirect and direct evaporative coolers (IEC and DEC) to meet the target supply air (SA) conditions. In this study, seawater was used ...

The objective of this study was to modify an existing liquid desiccant and indirect/direct evaporative cooling-assisted 100% outdoor air system (LD-IDECOAS) for humidification operation in winter. energy benefit the desiccant-assisted approach during LD-IDECOAS over conventional method with a steam humidifier evaluated through detailed simulation. enthalpy effectiveness values measured from lab...
