An absorption chiller includes a vertically split absorber section the upper portion of which is a high temperature absorber and the lower portion of which is a low temperature absorber. Weak solution is pumped in parallel from the absorber to both a low temperature generator and a high temperature generator. The low temperature generator is disposed vertically above the high temperature generator. Concentrated solution flows, in parallel, from the low temperature generator to the low temperature absorber and from the high temperature generator to the high temperature absorber. The flow of concentrated solution from the low temperature generator to the low temperature absorber is as a result of the elevation of the low temperature generator above the low temperature absorber while the flow of concentrated solution from the high temperature generator to the vertically elevated high temperature absorber is as a result of the pressure differential between the high temperature generator and the high temperature absorber.

A device for monitoring and modulating the admission of fresh air into a building. The device comprises a housing; a sensor associated with the housing and operable to measure airflow through the housing; and a damper including at least two damper blades. Each damper blade includes a shaft rotatably attached to the housing at least at a first shaft end. The shaft is located on the surface of the damper blade so as to divide the surface into first and second substantially equal areas.

An air handling unit has a fan wheel in offset placement and a plenum configuration preventing line of sight noise transmission into the air system supplied by the air handling unit. The fan wheel is so placed and the plenum configuration optimized so as to obtain the benefit of an eddy current stabilizer flow from the fan wheel, which provides a further improvement in the acoustic performance of the air handling unit.
