TL;DR: In this article, three types of fin-tube heat exchanger with different surface characteristics were prepared and the effects of the surface characteristic on the frosting and defrosting behaviors of the heat exchangers were investigated experimentally.

TL;DR: In this paper, the authors proposed a new solar assisted air source heat pump system with flexible operational modes to improve the performance of the heating system, and the results showed that the COP of the heat pump unit was enhanced with the increase of the solar radiation density during the typical sunny day in the heating season.

TL;DR: In this paper, the authors reviewed anti-frosting techniques in refrigeration and air conditioning fields, including air dehumidification by solid/liquid desiccant, ultrasonic vibration, external electric/magnetic field, surface treatment, etc.

TL;DR: In this paper, a new biomimetic method, inspired by the fog harvesting ability of hydrophobic-hydrophilic surfaces of Namib desert beetles, is presented, which envisages a low-cost preparation (by the photocatalysis of titanium dioxide through ultraviolet irradiation) of a titanium dioxide-silicon dioxide hybrid superwettable surface combining superhydrophobic and super hydrophilic nanoparticles and exhibiting excellent water/fog collection properties.

TL;DR: In this article, the authors proposed a heating tower heat pump (HTHP) as an alternative to the conventional air-source heat pump to investigate the performance improvements of the HTHP over the ASHP, a comprehensive comparison between the two systems was carried out based on simulation study.
