Abstract
A heat and mass exchanger for a liquid desiccant air conditioning/dehumidification system. The exchanger comprises an absorber solution section operably connected to the system's absorber/dehumidification section and a desorber solution section operably connected to the system's desorber/regeneration section. A partition separating those sections includes at least two interconnecting ports positioned to facilitate flow of relatively weak solution from the absorber solution section into the desorber solution section; and the flow of relatively strong solution from the desorber solution section into the absorber solution section—as well as allowing heat transfer therebetween.
Claims10
A heat and mass exchanger for an open-cycle liquid desiccant air conditioning/dehumidification system having an absorber/dehumidification section with an absorber and a desorber/regeneration section with a desorber, the exchanger comprising:
- an absorber solution section having an inlet for receiving weak liquid solution from the absorber/dehumidification section and an absorber solution section outlet disposed at or proximate the bottom of said absorber solution section from which strong liquid solution exits to the absorber/dehumidification section;
- a desorber solution section having an inlet for receiving regenerated liquid solution from the desorber/regeneration section and a desorber solution section outlet from which liquid solution to be regenerated exits to the desorber/regeneration section;
- a partition separating the absorber solution section and the desorber solution section, wherein said absorber solution section is disposed under at least a portion of said desorber solution section;
- and
- at least two section-connecting ports connecting between the absorber solution section and the desorber solution section, including a first section-connecting port disposed at or proximate the top of said partition and a second section-connecting port at or proximate the bottom of said partition,
- wherein during operation, the absorber solution section is full of relatively weak liquid solution which flows from the absorber solution section into the desorber solution section via the first section-connecting port;
- a relatively strong liquid solution flows from the desorber solution section into the absorber solution section via the second section-connecting port;
- a strong liquid solution exits the outlet of the absorber solution section;
- a liquid solution exits the desorber section via desorber solution section outlet;
- as well as there being heat transfer between the absorber solution section and the desorber solution section.
An open-cycle liquid desiccant air conditioning/dehumidification system comprising:
- an absorber/dehumidification section having an absorber for dehumidifying a fluid using a liquid desiccant solution;
- a desorber/regeneration section with a desorber for regenerating the liquid desiccant solution,
- further comprising a heat and mass exchanger for a liquid desiccant air Conditioning/dehumidification system having an absorber/dehumidification section with an absorber and a desorber/regeneration section with a desorber, the exchanger comprising:
- an absorber solution section having an inlet for receiving weak liquid solution from the absorber/dehumidification section and an outlet disposed at or proximate the bottom of said absorber solution section from which strong liquid solution exits to the absorber/dehumidification section;
- a desorber solution section having an inlet for receiving regenerated liquid solution from the desorber/regeneration section and an outlet from which liquid solution to be regenerated exits to the desorber/regeneration section;
- a partition separating the absorber solution section and the desorber solution section, wherein said absorber solution section is disposed under at least a portion of said desorber solution section;
- and
- at least two section-connecting ports connecting between the absorber solution section and the desorber solution section, including a first section-connecting port disposed at or proximate the top of said partition and a second section-connecting port at or proximate the bottom of said partition,
- wherein during operation, the absorber solution section is full of relatively weak liquid solution which flows from the absorber solution section into the desorber solution section via the first section-connecting port;
- a relatively strong liquid solution flows from the desorber solution section into the absorber solution section via the second section-connecting port;
- a strong liquid solution exits the outlet of the absorber solution section;
- a liquid solution exits the desorber section via desorber solution section outlet;
- as well as there being heat transfer between the absorber solution section and the desorber solution section.
