Heat and mass transfer advances for energy conservation and pollution control in a renewable and sustainable energy transition

In the face of increasing demands with regard to the share of renewable energy sources in the energy mix, adsorption chillers are becoming a potentially important part of the energy transition. A key component of this type of equipment is the heat exchanger in the adsorption bed, the design of which affects both heat and mass transfer. This study includes an analysis of the geometry and materials used to manufacture such heat exchangers. The geometry analysis is mainly based on the evaluation of the impact of the different dimensions of the exchanger components on heat and mass transfer in the bed. The second part of the study focuses on material-related issues where the main emphasis is on the analysis of the thermal inertia of the exchanger. The paper analyses the latest research on the design of exchangers in adsorption beds, mainly from 2015–2021. Currently, the commonly used SCP and COP coefficients and various test conditions do not provide sufficient information for comparative analysis of adsorption bed heat exchangers, so the authors propose to introduce a new index for the evaluation of heat exchangers in terms of the effect of the design parameters on the energy efficiency of an adsorption chiller.

Conservation And Management

In the twenty first century, the world is witnessing an unprecedented energy transition. This sustainability-driven transition, also termed the sustainable energy transition or low carbon transition, has four major dimensions: decarbonisation, decreased use, decentralisation, and digitalisation. Decarbonisation and decreased use of energy are already well established dimensions of the sustainable energy transition. Decreased use of energy through energy conservation and management (ECM) offers wide ranging benefits across all energy consuming sectors, i.e., buildings, industry, and transportation. The building sector, accounting for almost 40% of the world’s total energy consumption, is particularly conducive to ECM. Estimates suggest that with the reliable and commercially available solutions, energy demand in both new and existing buildings can be reduced by 30 to 80%.
