Embodiment Construction

[0026]FIG. 1 depicts a new type of liquid desiccant system as described in more detail in U.S. Patent Application Publication No. US 20120125020, which is incorporated by reference herein. A conditioner 101 comprises a set of plate structures that are internally hollow. A cold heat transfer fluid is generated in cold source 107 and entered into the plates. Liquid desiccant solution at 114 is brought onto the outer surface of the plates and runs down the outer surface of each of the plates. The liquid desiccant runs behind a thin membrane that is located between the air flow and the surface of the plates. Outside air 103 is now blown through the set of wavy plates. The liquid desiccant on the surface of the plates attracts the water vapor in the air flow and the cooling water inside the plates helps to inhibit the air temperature from rising. The treated air 104 is put into a building space.

[0027]The liquid desiccant is collected at the bottom of the wavy plates at 111 and is transpo...

Abstract

A split liquid desiccant air conditioning system is disclosed for treating an air stream flowing into a space in a building. The split liquid desiccant air-conditioning system is switchable between operating in a warm weather operation mode and a cold weather operation mode.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims priority from U.S. Provisional Patent Application No. 61 / 783,176 filed on Mar. 14, 2013 entitled METHODS AND SYSTEMS FOR MINI-SPLIT LIQUID DESICCANT AIR CONDITIONING, which is hereby incorporated by reference.BACKGROUND[0002]The present application relates generally to the use of liquid desiccants to dehumidify and cool, or heat and humidify an air stream entering a space. More specifically, the application relates to the replacement of conventional mini-split air conditioning units with (membrane based) liquid desiccant air conditioning system to accomplish the same heating and cooling capabilities as those conventional mini-split air conditioners.[0003]Desiccant dehumidification systems—both liquid and solid desiccants—have been used parallel to conventional vapor compression HVAC equipment to help reduce humidity in spaces, particularly in spaces that require large amounts of outdoor air or that have large humidi...
