Abstract: A liquid desiccant air conditioning system comprises an energy exchange unit comprising a sump and a plurality of media pads positioned above the sump, first, second, and third desiccant outlets fluidly connected to the sump, and at least one retractable gate positioned above the sump, configured to partition the sump into at least first and second compartments, wherein the first compartment is fluidly connected to the first desiccant outlet and the second compartment is fluidly connected to the second desiccant outlet, and wherein effective volumes of the first and second compartments can be modified by opening and closing the at least one retractable gate. A method of controlling desiccant circulation in a liquid desiccant air conditioning system is also described.

Abstract: Systems and methods for optimizing system efficiency and demand response performance for variable-fan-speed and variable-capacity air handling systems. A controller is provided selectively controlling building-zone dampers in response to acquired operational parameters, such that air flows through selected duct sections and not through the entire duct system simultaneously, wherein design velocity in each duct section is roughly maintained whenever the duct section is being used. Exemplary operational parameters include compressor speed, cooling capacity, heating capacity, fan speed, duct-section air flow, zone air flow, duct-inlet temperature, duct-outlet temperature, and duct-zone temperature.

Abstract: A system for heating and cooling multiple rooms includes a separate induced air heat transfer unit mounted adjacent to the ceiling in each room. Each unit includes a tubular cooling coil, a series of longitudinally spaced apart flat heat transfer fins mounted on the cooling coil, and an elongated, tubular plenum extending below the cooling coil. During the cooling cycle, chilled water is circulated through the cooling coil, and tempered air, i.e., fresh air which has been dehumidified below dew point, and preheated slightly above dew point (52*F.) in a remote central plant, is forced through the plenum. The tempered air is dispersed through slotted openings spaced along the length of the plenum to stimulate the natural convective flow of cool room air through the heat transfer unit. The supply and return pipes for the cooling coil in each room extend through the heat transfer fins and are coupled with a chiller in the central plant to provide continuous circulation of chilled water through the cooling coils. During the heating cycle, water circulation through the cooling coils is stopped, and tempered air is preheated in the central plant and forced through the openings in the plenum.

Abstract: An environmental control system for a building is shown. The system includes a control device operable affect a static pressure in a conduit, a building device operable to affect a flow rate of a fluid through the conduit, and a controller including a processing circuit configured to perform a volumetric control process to generate a control signal for the drive device. The processing circuit is further configured to receive an operating position signal of the control device. The processing circuit is further configured to determine an estimated static pressure level within the duct using the operating position signal of the control device and update the control signal based on the estimated static pressure level determined using the operating position. The processing circuit is further configured to operate the drive device based on the updated control signal to affect the flow rate of the fluid.
