  • the invention relates to a liquid desiccant dehumidification system comprising multiple regeneration towers and multiple absorbers to service to more than one area and to achieve energy and cost savings.
  • Air conditioning is an indispensable part of today's life. Numerous studies are carried out and new products are developed in order to achieve a qualified and healthy air conditioning. Undoubtedly, the most important parameters of the studies conducted for this purpose are energy requirement and economic cost.
  • Humidity control is vital both for daily life and for production processes in different industries. For this reason, it is important to control the humidity level of the environment, to keep it at the desired level and to follow this process. In particular, in recent years, researchers have been working extensively on desiccant dehumidification systems.
  • a typical liquid desiccant system comprises a dehumidifying section (absorber/conditioner) for removing moisture from humid air by using a liquid desiccant.
  • a regeneration section for re concentrating the liquid desiccant is also used in this system.
  • Liquid desiccant dehumidification systems which are widely used in the state of the art, perform an air conditioning (dehumidification) process at one point. For this reason, it is necessary to use large sized air ducts to allow distribution in large areas. This situation brings higher loads in terms of both volume and energy. It also imposes the necessity of mixing the air of independent sections that should not mix with each other.
  • a patent application with the publication number of US2019299158 A1 relates to a liquid desiccant system including a high desorber, a low desorber, and an absorber that are in fluid communication with a working solution, where the high desorber provides rejected water vapor from the working fluid for condensation in a condenser of the low desorber that provides heat for rejection of additional water from the working solution in the low desorber effectively multiplying the heat provided for desorption.
  • the low desorber provided the concentrated working solution to the absorber where water from ambient air is condensed into the concentrated working solution to provide a dilute working solution within a working solution conduit of the absorber that is thermally coupled to an internal cooler of the absorber.

  • the main objective of the invention is to provide a liquid desiccant dehumidification system comprising multiple regeneration towers and multiple absorbers to provide service to more than one area and to achieve energy and cost savings.

In this way, advantages are provided in terms of installation, energy consumption, costs and space saving in the facility.
  • Another objective of the invention is to perform the dehumidification process with shorter air ducts of much smaller size than the air ducts used in the state of the art.

  • At least one absorber liquid desiccant level control valve (10) per absorber (8) is used to maintain an appropriate level.

  • the purpose of the heater exchanger (13) is to increase the temperature of the liquid desiccant.
  • the purpose of the cooling exchanger (15) is to decrease the temperature of the liquid desiccant.
  • a transfer exchanger (14) the heat of the liquid desiccant passing from the regeneration region (H) to the absorption region (J) is transferred to the liquid desiccant passing from the absorption region (J) to the regeneration region (H).
