Abstract:
1. An energy measurement system for a fluid heating and cooling system, comprising: a primary fluid flow loop; a first secondary fluid flow loop and a second secondary fluid flow loop each being fluidly coupled to the primary fluid flow loop, the first secondary fluid flow loop exchanging heat with a heat load and the second secondary fluid flow loop exchanging heat with a heat source, the first and second secondary fluid flow loops each including an inlet and an outlet fluidly coupling the primary fluid flow loop to each of the first and second secondary fluid flow loops; a fluid flow meter coupled to the primary fluid flow loop between at least one of the outlet of the first secondary fluid flow loop and the inlet of the second secondary fluid flow loop and the outlet of second secondary fluid flow loop and the inlet of the first secondary fluid flow loop, the flow meter measuring a volumetric fluid flow of the flow within the primary loop at the position of the flow meter; a first temperature sensor coupled to the primary fluid flow loop, the first temperature sensor measuring the temperature of a fluid flowing in the primary fluid flow loop upstream of the inlet of the first secondary fluid flow loop; a second temperature sensor coupled to the primary fluid flow loop, the second temperature sensor measuring the temperature of the fluid in the primary fluid flow loop flowing downstream of the outlet of the first secondary fluid flow loop; a third temperature sensor coupled to the primary fluid flow loop, the third temperature sensor measuring the temperature of the fluid flowing in the primary fluid flow loop downstream of the outlet of the second secondary fluid flow loop; and a processor in communication with the first, second, and third temperature sensors and the fluid flow meter, the processor being configured to:
