Condensation Frosting Characteristics of SAM-Coated Nanostructured Superhydrophobic Surface
International Journal of Air-Conditioning and Refrigeration, 2018 The present study aims to experimentally investigate the condensation frosting characteristics of the SAM-coated superhydrophobic surfaces under various environmental conditions. The extensive experiments were carried out under the well-controlled conditions with the surface temperature ranging from [Formula: see text]C to [Formula: see text]C, the ...

A Review of Condensation Frosting
Nanoscale and Microscale Thermophysical Engineering, 2016abstractThe accretion of ice and frost on various infrastructure is ubiquitous in cold and humid environments, causing economic losses amounting to billions of dollars every year worldwide. The past couple of decades have seen unprecedented advances in the fields of surface chemistry and micro/nanofabrication, enabling the development of hydrophobic ...

Suppressing Condensation Frosting Using an Out-of-Plane Dry Zone
Langmuir, 2020The vapor pressure above ice is lower than that above supercooled water at the same temperature. This inherent hygroscopic quality of ice has recently been exploited to suppress frost growth by patterning microscopic ice stripes along a surface. These vapor-attracting ice stripes prevented condensation frosting from occurring in the intermediate ...

On Localized Vapor Pressure Gradients Governing Condensation and Frost Phenomena
Langmuir, 2016Interdroplet vapor pressure gradients are the driving mechanism for several phase-change phenomena such as condensation dry zones, interdroplet ice bridging, dry zones around ice, and frost halos. Despite the fundamental nature of the underlying pressure gradients, the majority of studies on these emerging phenomena have been primarily empirical. Using

Condensation Frosting on Micropillar Surfaces – Effect of Microscale Roughness on Ice Propagation
Langmuir, 2020Microscale surface structures have been widely explored as a promising tool for antifreezing or frost avoidance on heat transfer surfaces. Despite studies of many surface feature designs, the mechanisms associated with condensation freezing and ice propagation on microstructured surfaces have yet to be thoroughly elucidated, espectially when it comes ...

Applied Thermal Engineering, 2022
For a space heating ASHP unit, frosting on its outdoor coil would adversely impact its normal operation, requiring frequent defrosting and resulting in low operating efficiency and poor indoor thermal comfort. It has been shown that varying the speeds of both compressor and outdoor air fan in a variable speed (VS) ASHP unit can lead to different ...
