Abstract
A system for operating a cooling loop associated with a space and including at least one cooling coil and cooling fluid supply, the system including: a grain sensor positioned with respect to the space and providing a value indicative of the amount of moisture in the space; at least one pump fluidly coupled across the coil; at least one flow limiter fluidly coupled to the coil and limiting a flow of cooling fluid between the cooling fluid supply and the coil; and at least one controller electrically coupled to the flow limiter; wherein, the at least one controller selectively operates the flow limiter responsive to the value indicative of the amount of moisture in the space and the pump re-circulates cooling fluid independent of the cooling fluid supply dependently upon the flow limiter.
Claims18
A method for operating a chilled water system servicing a space of a building, the chilled water system including a cooling coil interconnected to a chilled water supply, the method comprising:
- determining a value substantially indicative of the absolute humidity of the building space, wherein air supplied to the building space is forced across the cooling coil such that heat is exchanged between the forced air and chilled water flowing through the cooling coil dependently upon a setpoint being responsive to a temperature and relative humidity of the building space, and chilled water flowing through the cooling coil in a laminar nature reduces the heat exchanged and a cooling efficiency associated with the building space;
- and
- mitigating occurrences of laminar flow through said cooling coil and the reduction in the cooling inefficiency by selectively recirculating at least part of the chilled water that flowed through the cooling coil through the cooling coil again independently of the chilled water supply and dependently upon the determined value substantially indicative of the absolute humidity of the building space.
