MARTHA’S VINEYARD, MA — This geothermal rescue was for a closed loop geothermal system that was seriously overheating during the cooling season. This system had ten vertical loops that served 11 heat ...

UNDERSTANDING CLOSED-LOOP FAN SPEED CONTROL By Ken W. Gay, SMSC When implementing cooling solutions for electronic equipment, system designers are confronted with a complex set of variables.

A microprocessor-based temperature control module is fully automatic and self-tuning, using selectable AccuComp Cycle or PID power control with fuzzy logic for reliability, precision, and minimal ...

"This target is $45 per megawatt-hour. We found that to achieve this goal using closed-loop systems in hot, dry rock, there would need to be a very aggressive reduction in the cost of drilling." ...

Typically, when using a condensing economizer on a boiler, the heat sink water is from the low-temperature hydronic heating system, and the boiler is typically a hot water boiler. We are applying some ...

An international research team has developed a closed-loop PV cooling system that can reportedly offer 24-hour continuous operation. The system is claimed to be particularly suitable for hot and ...
