Experimental Investigation on Self-cleaning Heat Exchanger in VRF System
Zhileng xuebao, 2021 Providing healthy air has become an important indicator of air conditioners. In this study, a self-cleaning heat exchanger was designed in a variable refrigerant flow air-conditioning system, and the potential of dedusting and sterilization of the ...

Evaporation and Antievaporation Instabilities [PDF]
Symmetry, 2017 We review (anti)evaporation phenomena within the context of quantum gravity and extended theories of gravity. The (anti)evaporation effect is an instability of the black hole horizon discovered in many different scenarios: quantum dilaton-gravity, f ( R ) -gravity, f ( T ) -gravity, string-inspired black holes, and brane-world cosmology ...

Work verification of the energy steam boiler evaporator in the Power plant 'Kostolac B' [PDF]
FME Transactions, 2012 Within Electric Power Utility of Serbia 1991, a thermal power plant 'Kostolac B', power 2 × 350 MW, started. Based on the examination of steam boiler pipe system, it is confirmed that it is in a 'bad' shape.

Physical Review E, 2023 Evaporation of a liquid layer on a substrate is examined without the often-used isothermality assumption -- i.e., temperature variations are accounted for. Qualitative estimates show that nonisothermality makes the evaporation rate depend on the conditions the substrate is maintained at.

Journal of High Energy Physics, 2014 In this note, we begin by reviewing an argument (independent from 1304.6483) that the large AdS black holes dual to typical high-energy pure states of a single holographic CFT must have some structure at the horizon (i.e. a firewall/fuzzball). By weakly coupling the CFT to an auxiliary system, such a black hole can be made to evaporate. In a case where
