    摘要： Turbulators are disclosed for use in a high-stage generator for an exhaust-fired absorption chiller/heater. The turbulators are designed to minimize pressure drop across the turbulator, and thus minimize the efficiency loss to the exhaust source. One turbulator design has a number of flanges extending at a non-normal angle to a central web. Further, some of the flanges have cutout portions. The overall turbulator design is intended to minimize wake downstream of the turbulator blades, which could otherwise cause undesirable pressure drop. A second turbulator design incorporates flanges that extend at a normal angle relative to the central web, but wherein the flanges have a non-rectangular cross-sectional shape. Again, the goal of the turbulator designs here is to minimize wake, and potential pressure drop.

    摘要： A combined vapor compression and vapor expansion system uses a common refrigerant which enables a super-critical high pressure portion and a sub-critical low pressure portion of the vapor expansion circuit. Provision is made to combine the refrigerant flow from the vapor expander and from the compressor discharge. The outdoor heat exchanger is so sized and designed that the working fluid discharged therefrom is always in a liquid form so as to provide a liquid into the pump inlet. The pump and expander are so sized and designed that the high pressure portion of the vapor expansion circuit is always super-critical. A topping heat exchanger, liquid to suction heat exchanger, and various other design features are provided to further increase the thermodynamic efficiency of the system.

    摘要： A system for controlling an absorption chiller includes feedback control loops determining adjustments to system cooling and heating capacities and a controller for simultaneously adjusting positions of an energy input valve, a hot water valve, and a chilled water valve. The controller adjusts valves based on desired adjustments to system cooling and heating capacities and performance maps characterizing relationships between cooling capacity and heating capacities and valve positions. A method for controlling an absorption chiller includes the step of obtaining a performance map characterizing heat energy input to cooling and heating loops as functions of valve positions. To obtain the map, the hot water valve is held in a substantially constant position while the chilled water valve is modulated. Similarly, the hot water valve is modulated while the chilled water valve is held in a substantially constant position.

    摘要： A cooling, heating and power system (10) includes a prime mover (12) for producing electricity having a thermal output (18) and an electrical output (20) coupled to an absorption chiller (24). A part-load, active, redundant chiller (26) is thermally coupled to the absorption chiller (24) for receiving a cooling-heating fluid from the absorption chiller (24). The part-load chiller (26) operates at maximum efficiency at between about forty percent and about sixty percent of a maximum cooling load of the chiller (26) to thereby generate large volumes of cooling very efficiently. The system (10) may direct the cooling into a multi-zone cooling-heating circuit (40) including a critical zone (42) and a utility zone (44) thermally coupled to the chiller (26) for selectively delivering the cooling-heating fluid to at least one of the critical zone (42) and the utility zone (44) of the circuit (40).

    摘要： A CHP system can include one or more heat sources generating heat output and producing emissions. The CHP system can further include one or more power converters configured to convert the heat into a useful power output. The power converters can deliver the balance of heat to one or more thermally-activated devices (TADs) configured to convert the heat into a useful thermal (heating and cooling) output. The method for configuring the CHP system can comprise the steps of: representing the useful power output by the power converters as a function of the heat output by the heat sources; representing the useful thermal output by the TADs as a function of the heat output by the heat sources; representing the specific emission output as a function of the heat output by the heat sources; and determining the values of the individual heat source heat output which are sufficient to attain the pre-defined levels for useful power output and useful thermal output, while meeting the regulated specific emission levels.
