The framework integrates a “shared-specialized collaborative” cross-domain network to balance feature generality and domain specificity, a dynamic weighted adversarial subdomain alignment mechanism based on information entropy to learn batch-level weights for source–target pairs, and a semi-supervised learning strategy with an auxiliary regularizer to stabilize transfer under limited target labels.

This study addresses the need for a quantitative, multi-market assessment of how residential flexibility from energy communities can be optimally scheduled considering a case study in Portugal. The central premise is that an independent aggregator can pool and manage residential flexibility in ways that generate additional value streams for both the community and the aggregator through differentiated market-participation strategies. A multi-objective optimisation framework is applied to a residential energy community equipped with photovoltaic generation, a battery energy storage system, and flexible loads. A profit-redistribution mechanism to co-optimise community cost savings and aggregator profit from trading flexibility is tested across the Day-Ahead, Intraday, automatic Frequency Restoration Reserve, and Local Flexibility Markets. Results show aggregator net profits between 1.0–19.5%, up to 1281 €/year, and community energy cost reductions between 2.0–28.8%, up to 405 € annually by participant, with revenue stacking providing additional gains. Peak-load reductions reach up to 17%, while the Self-Sufficiency Ratio varies from 29.7% to 31.4%. Reserve services and local flexibility markets deliver higher economic benefits than wholesale price arbitrage, but their practical use is constrained by market entry thresholds, respectively 1 MW and 0.01 MW.

Despite advances in refrigeration technologies, integrated approaches combining heat recovery and evaporative pre-cooling remain underexplored. To address this research gap, this study investigates the potential of integrating an intermediate heat exchanger with a nebulizer to enhance the performance of an air-cooled vapor compression refrigeration cycle. An experimental setup comprising a 200 cm × 35 cm × 35 cm air-conditioning tunnel and a 3.5 kW R404a refrigeration cycle equipped with PLC-based temperature and pressure monitoring was constructed under controlled laboratory conditions. Airflow and temperature were controlled using a variable-speed blower and PID-regulated heaters/evaporator, while water flow through a shell-and-tube heat exchanger (preheating domestic water for later use) was varied from 60 to 240 L/h. Results indicate that increasing water flow to 240 L/h reduces compressor power consumption by 17% and improves the system’s coefficient of performance by more than threefold. Similarly, lowering the condenser inlet air temperature by 7 °C using a nebulizer decreases compressor power demand by 3.8% and enhances the coefficient of performance by 1.53-fold. Economic analysis shows that heat recovery with a water flow rate of 210 L/h can achieve annual savings of approximately $300, whereas the nebulizer implementation entails a payback period exceeding five years. Furthermore, the nebulizer offers a strategic operational benefit by preventing system shutdown during periods of high ambient temperature (exceeding the refrigeration cycle’s design point) through condenser cooling, thereby avoiding operational interruptions and potential losses. These findings demonstrate the substantial technical and economic benefits of combining heat recovery and evaporative pre-cooling in conventional refrigeration systems, offering a promising strategy for energy-efficient and sustainable cooling.</div></div>","PeriodicalId":11664,"journal":{"name":"Energy Conversion and Management","volume":"353 ","pages":"Article 121198"},"PeriodicalIF":10.9,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146153039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this article is to investigate the optimal mix of energy potential available with resources such as Vehicle-to-Grid (V2G) and CEV vehicles supported by a local diesel generator. The article proposes a research methodology for assessing the economic viability of deploying energy services using MESF to improve the energy security of priority loads, especially critical infrastructure sites by minimizing the cost of electricity supply from the BPR mix. The reference point is the value of energy not delivered, estimated using the value of lost load (VOLL) indicator. The study included 18 test simulations of BPR resource dispatch over the course of a year, considering the hourly power demand profile of the end-user and the probability of grid constraints. The results indicate that economic viability is achieved when service activation exceeds 125 h, and the profits from using such resources can reach almost EUR 2 million. For 6 out 18 applied testing scenarios, the profits of using BPR’s optimal mix were recorded, ranging from 168,000 EUR to 1,824,693 EUR.

Results indicate that a system with a dual-wing fracture attains moderately greater heat extraction than a fracture-free closed-loop design, when the fracture has large height and thickness, with performance increasing as fracture heat conductivity rises.

This study proposes an innovative approach that couples near-ambient-temperature phase-change heat absorption under sub-atmospheric pressure with high-temperature hydrogen–oxygen direct combustion. A semi-closed Rankine cycle, synergistically driven by hydrogen–oxygen combustion and low-grade thermal input, is constructed accordingly. Owing to its compatibility with sub-atmospheric pressure conditions and adaptability to low-grade heat, the proposed cycle is highly suitable for integration with emerging energy storage technologies such as near-atmospheric-pressure solid-state hydrogen storage. Using low-grade solar energy as an example, the system exploits the low saturation temperature (∼60 °C) of water under sub-atmospheric pressure (0.02 MPa) to achieve efficient boiling heat transfer driven by solar energy, effectively mitigating the regeneration difficulty associated with large latent heat in subcritical Rankine cycles; combined with hydrogen–oxygen combustion, a regenerative process is employed to allocate high- and low-grade heat, thereby improving hydrogen utilization. Thermodynamic analysis and numerical simulation of sub-atmospheric water phase-change heat transfer verify the feasibility of the proposed system. At main steam conditions of 0.02 MPa and 1190 °C, thermal efficiencies of 23.51% and 83.24% (hydrogen fuel utilization efficiency excluding solar heat input) are obtained when low-grade solar heat is considered and not considered, respectively. Given the abundance and negligible cost of ∼ 60 °C solar energy, the 83.24% efficiency, equivalent to the theoretical limit of hydrogen–oxygen fuel cells, acquires realistic engineering significance. Numerical results further indicate that vapor quality is inversely correlated with flow velocity and positively correlated with solar irradiance; for an 11.7 m tube, the average outlet vapor quality reaches 83%, confirming engineering feasibility.
