A liquid desiccant system includes a liquid desiccant loop having an absorber unit in fluid communication with a desorber unit and liquid desiccant flowing between the absorber unit and the desorber unit. The liquid desiccant system includes a supply airflow path passing through the absorber unit and forming an absorber liquid / air interface within the absorber unit and a conditioned airflow exiting the absorber unit. The liquid desiccant system includes a regeneration airflow path passing through the desorber unit and forming a desorber liquid / air interface within the desorber unit and an exhaust airflow exiting the desorber unit. A heat exchanger is thermally coupled to the supply airflow path for removing heat from supply airflow upstream of the absorber unit. A heat exchanger is thermally coupled to the regeneration airflow path adding heat to regeneration airflow upstream of the desorber unit.

A liquid desiccant (LD) based dehumidification system is provided for heating, ventilation, air conditioning, and refrigeration (HVAC&R) systems. The LD based dehumidification system includes a contact media device including a media for being disposed in an air stream to be dehumidified, a surfactant, and a LD for wetting the media. The LD is dosed with the surfactant to adjust the wettability of the media by the LD.

A regeneration system includes: a liquid desiccant regeneration loop including a liquid desiccant tank and a heat and mass exchanger; and a refrigerant circuit including a first heating zone and a second heating zone, where a temperature in the first heating zone is higher than a temperature in the second heating zone. Low-concentration liquid desiccant in the liquid desiccant tank sequentially flows from the second heating area to the first heating area, then passes through the heat and mass exchanger and is stored as high-concentration liquid desiccant; and a portion of the low concentration liquid desiccant exiting the first heating zone or the second heating zone is used as a heating fluid for the heat and mass exchanger. A method of operating such a regeneration system is also provided.

A liquid desiccant (LD)-based dehumidification system is provided for heating, ventilation, air conditioning, and refrigeration (HVAC&R) systems. The LD-based dehumidification system includes a tank containing LD, a contact media device including media for being disposed in an air stream to be dehumidified and a sump disposed below the media to receive the LD drained from the media, a pump and valve system for pumping the LD from the tank to the contact media device to wet the media and from the sump to the tank, a heat exchanger through which the LD pumped from the sump to the tank flows, a sensing system for sensing one or more conditions of the LD, and a controller for controlling the pump and valve system in accordance with system status and the one or more conditions of the LD.

This application relates to the application and method of using orthoester compounds, and a vacuum insulation panel, belonging to the field of drying materials technology. The application includes using orthoester compounds as liquid desiccants. Orthoester compounds readily react with water at room temperature, efficiently capturing trace amounts of moisture in the system. Simultaneously, the reaction of orthoester compounds with water generates corresponding alcohols and esters. The generated alcohols and esters evaporate completely at low temperatures, leaving no residue, thus facilitating drying at low temperatures. Therefore, orthoester compounds can be used as liquid desiccants to efficiently remove trace amounts of moisture from the system at low temperatures, thereby improving drying efficiency.
