A Review of Defrosting Technologies for Air Source Heat Pumps

Frontiers in Science and Engineering
Air source heat pumps (ASHPs) are widely used in building energy efficiency due to their high performance and environmental benefits. However, in cold climates, frosting of ASHP evaporators during winter operation reduces heating efficiency, affects user comfort, and may even cause system shutdowns or permanent damage.

Meniscus Pixel Printing for Contact‐Lens Vision Sensing and Robotic Control

Advanced Functional Materials, EarlyView.
A visual‐sensing contact lens is enabled by meniscus pixel printing (MPP), which rapidly patterns a 200 µm perovskite photodetector pixel in 1 s without masks, vacuum processing, or bulky equipment. A deep‐learning‐based super‐resolution reconstructs sparse on‐lens signals into 80 × 80 high‐resolution visual information, while AI‐driven eye‐tracking ...

Carbon Dioxide Emissions from a Ground Heat Pump for a Detached House

Proceedings, 2019
Inasmuch as the European Union promotes only energetically viable heat pumps in a given location, the aim of the work is an assessment of whether a ground-to-water heat pump (ground source heat pump: GSHP) can be considered as an ecological heat ...

Thermodynamic Analysis of an Air Source Compression Heat Pump [PDF]

, 2020
The aim of this paper is to evaluate air source heat pump efficiency using energy and exergy analyses for different evaporating temperatures and compressor isentropic efficiencies. For each case of different evaporating temperature and compressor isentropic efficiency, the heat pump coefficient of performance (COP), irreversibility and exergy ...
