Scheduling of Multiple Chillers in Trigeneration Plants

open access: yesEnergies, 2015
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

open access: yesEnergies, 2022
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

open access: yesCase Studies in Thermal Engineering, 2021
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.

Optimal Cooling Load Sharing Strategies for Different Types of Absorption Chillers in Trigeneration Plants

open access: yesEnergies, 2016
Trigeneration plants can use different types of chillers in the same plant, typically single effect and double effect absorption chillers, vapour compression chillers and also cooling storage systems.

Study on Relative COP Changes with Increasing Heat Input Temperatures of Double Effect Steam Absorption Chillers

open access: yesMATEC Web of Conferences, 2016
Absorption chillers at cogeneration plants generate chilled water using steam supplied by heat recovery steam generators. The chillers are mainly of double effect type.

Formulation of Coefficient of Performance Characteristics of Water-cooled Chillers and Evaluation of Composite COP for Combined Chillers

open access: yesEnergies, 2020
The Coefficient of Performance of an ordinary water-cooled chiller is presented as a relationship with the chiller load factor and cooling water temperature. However, the cooling water temperature fluctuates according to the processed heat of the cooling

Lithium Intercalation in the Anisotropic Van Der Waals Semiconductor CrSBr

open access: yesAdvanced Functional Materials, EarlyView.
We report the lithium intercalation in the layered van der Waals crystal CrSBr, revealing strongly anisotropic ion‐migration dynamics. Optical and electrical characterization of exfoliated CrSBr shows lithium diffusion coefficients that differ by more than an order of magnitude along a‐ and b‐directions, consistent with molecular dynamics simulations ...

A Modified DOE-2 Model for Typical Performance of Absorption Chillers and its Application

open access: yesZhileng xuebao, 2007
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.

Performance Analysis of Low-Capacity Water–LiBr Absorption–Cooling Systems Using Geothermal Heat-Sinks in Hot Climates

open access: yesEnergies, 2023
This paper addresses the use of a geothermal heat-sink to remove the heat released in domestic-sized single and double-effect water–LiBr absorption chillers operating in hot climates.
