Researchers in Spain have developed a dual-condenser air-to-water heat pump that shifts domestic hot water production to daylight hours, maximizing PV self-consumption. The prototype boosted solar ...

Opposition is growing among regional levee commissioners to the Army Corps of Engineers' plan for dual pumping stations on three New Orleans canals, one station to drain neighborhoods and another to ...

Researchers at the University of Padua in Italy have designed a dual-source heat pump that uses CO2 as the refrigerant and a solar evaporator comprising three PV-T collectors “The key innovation lies ...

i. Lead secondary chilled water pump will be enabled anytime the chilled water (CHW) system is enabled and will remain enabled for 30 minutes after the CHW system is disabled. b. Pump speed control i.

Part I of this series introduced the lead/lag control strategy as it applies to parallel pump operation and discussed the need for identifying the designer’s intent for a particular system. Part II ...
