In some embodiments, a method for analysis of a desiccant air processing unit includes receiving an air characteristic and generating, based on the air characteristic, a psychrometric chart with a representation of the air characteristic. The method includes determining, based on the air characteristic and a plurality of air processing units, a subset of air processing units and generating, based on the subset of air processing units and the air characteristic, output data associated with possible outputs from the subset of air processing units. The method includes defining a set of regions on the psychrometric chart based on the output data associated with each air processing unit from the subset of air processing units, each region from the set of regions being associated with a different air processing unit from the subset of air processing units and sending, to a user device, the psychrometric chart for output.

Apparatus and methods for user interface for efficient analysis and selection of desiccant HVAC systems

Liquid desiccant air conditioning systems and methods to operate them to achieved desired supply air dry bulb temperature and humidity conditions are described herein. In some embodiments, the liquid desiccant air conditioning systems can include a cooling unit, an absorber, a regenerator, and a control unit. The control unit can be operably coupled to the cooling unit, the absorber, and the regenerator such that the control unit can operate the liquid desiccant system to produce a supply air stream at a relatively independent target temperature and humidity. In some embodiments, the control unit can adjust one or more parameters and/or variables of the components of the liquid desiccant system to produce the supply air stream at a high energy efficiency.

Liquid desiccant air conditioning system and control methods

A liquid desiccant regenerator configured to produce a first output stream with a higher concentration of a liquid desiccant than a first input stream. The regenerator also produces a second output stream with a lower concentration of the liquid desiccant than a second input stream. Regeneration of the liquid desiccant in the liquid desiccant regenerator decreases a temperature of the liquid desiccant regenerator. The system includes an air contactor coupled to the first output stream and exposing an input air stream to the first output stream. The first output stream absorbs water from the input air stream to form at least one diluted output desiccant stream. A heat pump of the system is thermally coupled to move the heat from the first output stream to the liquid desiccant regenerator. The heat moved to the liquid desiccant regenerator increases an efficiency of the liquid desiccant regenerator.
