Embodiment Construction

[0022]Referring to the drawings in detail, a cooling, heating and power system with an integrated part-load, active, redundant chiller of the present disclosure is generally designated by the reference numeral 10. The system 10 includes a prime mover 12 that receives fuel, such as natural gas, from a fuel source 14 through a fuel inlet line 16 to produce electricity. The prime mover 12 may be any apparatus capable of producing electricity, such as a microturbine(s) mechanically coupled to an electric generator(s), a diesel or gas engine, a fuel cell, etc., and that also generates waste heat. The primer mover 12 also includes a thermal output 18 and an electrical output 20, and may also include a primary electrical line 22 for delivering additional electricity produced by the prime mover 12.

[0023]The system also includes an absorption chiller 24 for producing cooling and heating and the absorption chiller 24 is thermally coupled and electrically coupled to the thermal output 18 and t...

Abstract

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).

Description

CROSS REFERENCE TO RELATED APPLICATION [0001]This Application claims the benefit of U.S. Provisional Patent Application Ser. No. 61 / 069,276 that was filed on Mar. 12, 2008, entitled “Redundant Cooling Integrated with CHP”.TECHNICAL FIELD [0002]The present disclosure relates generally to use of cooling, heating and power systems (occasionally referred to as “CHP”, or “CCHP” for “combined cooling, heating and power”) that include a prime mover for producing electrical and / or mechanical energy that is thermally and electrically coupled with an absorption chiller for producing cooling and heating for such things as buildings having data centers, hospitals, etc. More particularly, the disclosure includes such a CHP system with an integrated part-load, active, redundant electric chiller and a system controller to provide more efficient cooling with a capacity for more efficient peak and back up cooling capacity.BACKGROUND ART [0003]Providing cooling, heating and power to modern structures...
