When is the Ambient Temperature Too Hot to Rely on Air to Air Heat Exchangers for Enclosure Cooling?
When you are looking for an efficient method for enclosure cooling, a heat exchanger is a good solution for a few different reasons. Not only is a heat exchanger energy efficient, but it allows you to maintain a completely closed loop enclosure cooling solution. The way a heat exchanger operates is by employing a heat pipe principle to exchange heat from an electrical enclosure to the outside. ...

The performance and emission characteristics of a diesel engine using preheated Kusum oil and Kusum diesel blend
Rapidly depleting conventional petroleum resources have prompted research for alternative fuels. Among various possible options for internal combustion engines, fuels derived from triglycerides (vegetable oils/animal fats) are a promising substitute for diesel fuel. Vegetable oils pose some detrimental characteristics like high viscosity and low volatility compared to diesel fuel. In the present ...

A study on the thermodynamic analysis of a cascaded latent heat storage system over the single storage tank system for diesel engine waste heat recovery
This article presents the comparison of performance of a cascaded Latent Heat Storage (LHS) system over the Single Storage Tank (SST) system for heat recovery from a diesel engine. The energy and exergy saved and efficiencies during the charging process are evaluated and reported using actual system data. The discharge process is analysed with a case study and it is concluded that it is possible ...

Maximising biogas in anaerobic digestion by using engine waste heat for thermal hydrolysis pre-treatment of sludge
EXECUTIVE SUMMARY Dublin's Ringsend WWTP was designed to serve a population of approximately 1.2 million pe with a sludge production of 37,000 dry tonnes per year after upgrading to full secondary treatment. Several technical solutions were put forward as part of a Design, Build, Finance and Operate (DBFO) competition, with the chosen solution being a proposal by Black and Veatch for a ...

What is "Net-Zero Cooling To Power"
Rankine Cycle and Organic Rankine Cycle Waste heat is a vast, underutilized, and sustainable source of energy that is often overlooked due to the costs involved with capturing and converting that heat into electricity. Rankine cycle (RC) systems have been used for decades to generate clean electricity from heat, however these systems are restricted to sources of high-temperature heat such as ...

SGBI opinion article: shale gas
Government perceives electric vehicles to be a panacea that will solve problems surrounding air quality and CO2 emissions simultaneously. The EV has two main selling points: reduced CO2 emissions and high efficiency. However, these are only valid at a superficial level and the argument disintegrates under any level of scrutiny. In terms of CO2 emissions, EVs replace ‘average’ cars to ...
