The Effects of Using Steam to Preheat the Beds of an Adsorption Chiller with Desalination Function
Adsorption chillers are a promising alternative to traditional compressor-based devices. Adsorption chillers can be supplied with low- or medium-temperature waste heat or heat from renewable energy sources.

Scheduling of Multiple Chillers in Trigeneration Plants
The scheduling of both absorption cycle and vapour compression cycle chillers in trigeneration plants is investigated in this work. Many trigeneration plants use absorption cycle chillers only but there are potential performance advantages to be gained ...

Possibilities of Using Zeolites Synthesized from Fly Ash in Adsorption Chillers
Adsorption chillers produce cold energy, using heat instead of electricity, thus reducing electrical energy consumption. A major industrial waste, fly ash, can be converted to zeolite and used in adsorption chillers as an adsorbent.

Exergetic optimization of absorption chillers – A case study
The best way to meet the European Union's energy awareness goals is to use a heat pump/refrigerator that requires renewable energy or waste heat to operate. Absorption machines are often powered by renewable energy or waste heat.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

A Modified DOE-2 Model for Typical Performance of Absorption Chillers and its Application
LiBr-water absorption chillers are commonly adopted in multifunction energy systems. The empirical part-load performance model for chillers presented by DOE-2 is one of the analytical methods to solve chiller performances.

COFs on MOFs: Layer‐by‐Layer Synthesis of MOF@COF Nanoparticles with Synergistic Adsorption
A layer‐by‐layer strategy enables the growth of crystalline covalent organic framework (COF) shells on metal–organic framework nanoparticles, creating core–shell structures with tunable porosity. Ordered interstitial mesopores are formed during shell growth, which are connected with the COF's intrinsic micropores, thereby enhancing water sorption. This
