Virtual moveable endcap non-reversing heater chiller system

Abstract

The invention sets out a system of interconnected non-reversing heater-chiller modules having a virtual moveable endcap separating select units. The system facilitates the variable operation of heater/chiller modules in a combination of heating/chilling/simultaneous operation modes, or rest modes, in order to adjust to variable building load, mechanical, and environmental conditions.

1 . A building space heating and cooling system, comprising:
 a building space to be conditioned,   a heat sink/source,   at least two modular non-reversing heater chillers connected in parallel,   each of said non-reversing heater chillers having a condenser, an evaporator, a condenser control/isolation valve, and an evaporator control/isolation valve,   a building conditioning fluid conduct containing building conditioning fluid,   said building conditioning fluid conduct being in heat transfer connection with the evaporators, the condensers, said heat sink/source, a building space cooling side heat exchanger, and a building space heating side heat exchanger,   virtual moveable endcap valves disposed in said building conditioning fluid conduct to variously isolate or communicate heat transferred out of said condensers and heat transferred into said evaporators with said building conditioning fluid,   wherein each of said modular non-reversing heater chillers can be selectively operated to send heat transferred from its respective condenser to said building conditioning fluid either to said building space heating side heat exchanger or to said heat sink/source, and to send building conditioning fluid having heat removed from it by said respective evaporator either to said building space cooling side heat exchanger or to said heat sink/source.   
     
     
         2 . A building space heating and cooling system,
 according to  claim 1 ,   comprising a plurality of modular non-reversing heater chillers numbered  1 -n connected in parallel, said modular non-reversing heater chillers having said respective condensers numbered  1 -n and said respective evaporators numbered  1 -n,   said respective condensers and evaporators being selectively separable via said virtual moveable endcap valves such that any or all of said condensers  1 -n and any or all of said evaporators  1 -n may be selectively isolated from said building space heating side heat exchanger and said building space cooling side heat exchanger respectively, and said heat sink/source.
