Methods and apparatus for recirculating air in a controlled ventilated environment. In one example, recirculation of air from one or more rooms in a multiple room ventilated environment having a common source of supply air is controlled such that minimum ventilation and thermal load requirements for each room are satisfied independently, so as to facilitate a reduction in the amount of fresh outside air required for the environment. In another example, the controlled airflows in each room may be based additionally on respective air quality levels of the air drawn from each room. In one aspect, if contaminants are detected in one or more rooms of the ventilated environment, the amount of air recirculated from a contaminated room back to the environment may be controlled based on a detected level of the contaminant and a dilution ratio of any returned contaminated air to the total uncontaminated air supplied to the environment.
In a ventilated environment including at least a first room and a second room ventilated by a common source of supply air, the first room having drawn therefrom first return air that constitutes a first portion of air returned to the ventilated environment as at least some of the supply air, the second room having drawn therefrom second return air that constitutes a second portion of the air returned to the ventilated environment as at least some of the supply air, a method of controlling a level of at least one contaminant in the supply air, comprising an act of:
A computer readable medium encoded with at least one program for execution on at least one processor associated with a ventilated environment including at least a first room and a second room ventilated by a common source of supply air, the first room having drawn therefrom first return air that constitutes a first portion of air returned to the ventilated environment as at least some of the supply air, the second room having drawn therefrom second return air that constitutes a second portion of the air returned to the ventilated environment as at least some of the supply air, the at least one program, when executed on the at least one processor, performing a method of controlling a level of at least one contaminant in the supply air, the method comprising an act of:
A controller to control a level of at least one contaminant in a common source of supply air for a ventilated environment that includes at least a first room and a second room supplied by the supply air, the first room having drawn therefrom first return air that constitutes a first portion of air returned to the ventilated environment as at least some of the supply air, the second room having drawn therefrom second return air that constitutes a second portion of the air returned to the ventilated environment as at least some of the supply air, the controller independently controlling at least one of a first flow of the first return air and a second flow of the second return air based at least on a contaminant level of the at least one contaminant in at least one of the first room and the second room.
In a ventilated environment including at least a first room and a second room ventilated by a common source of supply air, the first room having drawn therefrom first return air that constitutes a first portion of air returned to the ventilated environment as at least some of the supply air, the second room having drawn therefrom second return air that constitutes a second portion of the air returned to the ventilated environment as at least some of the supply air, a method of determining a threshold value for a contaminant level of at least one contaminant in at least one of the first room and the second room, comprising acts of:
In a ventilated environment including at least a first room and a second room, the first and second rooms being ventilated by a common source of supply air, a method for ventilating at least the first and second rooms, comprising an act of:
A computer readable medium encoded with at least one program for execution on at least one processor associated with a ventilated environment including at least a first room and a second room, the first and second rooms being ventilated by a common source of supply air, the at least one program, when executed on the at least one processor, performing a method for ventilating at least the first and second rooms, the method comprising an act of:
In a ventilated environment including at least a first room and a second room, the first and second rooms being ventilated by a common source of supply air, a ventilation system comprising:
