District energy systems can not only reduce consumption but also set supply dispatching schemes according to demand. In addition economic cost, and pollutant are more worthy of attention when evaluating combined cooling, heating power (CCHP) models. this paper, the CCHP model is established with objective primary consumption, emissions. The mathematical expression system proposed, a multi-objec...

This paper presents exergy and exergoeconomic analysis and parametric study of a Diesel engine based Combined Heat and Power (CHP) system that produces 277 kW of electricity and 282 kW of heat. For this purpose, the CHP system is first thermodynamically analyzed through energy and exergy. Then cost balances and auxiliary equations are applied to subsystems. The exergoeconomic analysis is based ...

Using a simple analytic approach we address the question of whether radiative cooling, nongravitational heating and cooling plus heating models can simultaneously explain the observed global X-ray properties (entropy and X-ray luminosity distributions) of groups and clusters and the residual soft Xray background (XRB) after discrete sources are removed. Within the framework of typical cold dark...

Abstract In order to further promote the new energy consumption of combined cooling, heating, and power (CCHP) microgrid, reduce carbon emissions, optimize total operating cost a low-carbon optimal scheduling model CCHP microgrid was proposed. It considered demand response (DR) shared storage (SES). Firstly, concept SES its operation mode are applied microgrid. Secondly, in take advantage flexi...

A typical problem in Northeast China is that a large amount of surplus electricity has arisen owing to the serious photovoltaic power curtailment phenomenon. To effectively utilize excess power, hybrid energy system proposed uses produce hydrogen this paper. It combines solar energy, production system, and Combined Cooling Heating Power (CCHP) realize cooling, heating, generation. The supplies ...

Electric drive vehicles (EDVs) have complex thermal management requirements not present in conventional vehicles. In addition to cabin conditioning, the energy storage system (ESS) and power electronics and electric motor (PEEM) subsystems also require thermal management. Many current-generation EDVs utilize separate cooling systems, adding both weight and volume, and lack abundant waste heat f...
