A district energy system includes at least one energy provisioning unit, an energy management controller; a thermal distribution network coupled to the energy provisioning units and to a plurality of coupling interfaces connectable to the associated HVAC system of buildings within a district, and an electrical distribution network coupled to the energy provisioning units and to the coupling interfaces. The coupling interfaces may include both heat pumps and heat exchangers at each building, to provide heating, cooling and enable harvesting of normally wasted thermal energy from the buildings for re-distribution. The controller can manage the selection and number of energy provisioning units (and their operational set points) coupled to the district thermal distribution network and the electrical distribution network to meet the thermal and electrical demands of the district while satisfying other operational goals such as the minimization of greenhouse gas emissions.

This disclosure relates to the field of energy recovery systems, and more particularly to exhaust heat recovery devices and exhaust flow control devices.

Energy recovery system

A heat exchanger, turbulizer or heat transfer surface, and a method of making same wherein the turbulizer is a corrugated member having parallel, spaced-apart ridges and planar fins extending therebetween. The planar fins have spaced-apart apertures with opposed peripheral edge portions including transversely extending flanges.

Heat transfer surfaces with flanged apertures

A combined EGR cooler and non-thermal plasma device has first and second fluid passageways which are in heat exchange communication with one another. One or more electrodes are located in the second fluid passageway. The electrodes are connected to a voltage source. When a voltage of sufficient magnitude is applied to the electrodes, a non-thermal plasma is generated in the second fluid passageway. The device can be constructed in the form of a shell-and-tube heat exchanger or a stacked-tube type heat exchanger, wherein the electrodes extend through the heat exchange tubes. Hot exhaust gases preferably flow through the tubes in heat exchange contact with a liquid coolant, thereby cooling the exhaust gases. The electrodes generate non-thermal plasma inside the tubes, converting at least a portion of the NO in the exhaust to NO, which reacts with soot in the exhaust gases to generate COand N, thereby cleaning the exhaust gases.

Combined EGR cooler and plasma reactor

A thermal management system has a high temperature heat transfer circuit and a low temperature heat transfer circuit for modulating the temperature of heat-generating components having different operating temperatures. The heat transfer circuits are in flow communication and are interdependent so that a single circulating pump can be used to pump a liquid heat transfer medium through both circuits. One of the heat transfer circuits comprises a continuous loop and the other heat transfer circuit comprises an open loop having a first end and a second end at which it is in flow communication with the first heat transfer circuit. Each heat transfer circuit is provided with a heat exchanger to modulate temperature of the heat transfer medium.
