Abstract
An air conditioning and water producing system includes a heat pumping unit and a membrane contactor in thermal communication with the heat pumping unit. The membrane contactor is configured such that a first brine flow is cooled by the heat pumping unit and diluted at the membrane contactor. A distiller is in thermal communication with the heat pumping unit and the membrane contactor such that a second brine flow is heated by the heat pumping unit and conveyed through the distiller. Thermal interaction between the second brine flow and the first brine flow flowing through the distiller extracts water from the second brine flow.
Claims7
A method of extraction of water from air comprising:
- cooling a first brine flow at an evaporator of a heat pumping unit;
- absorbing moisture into the first brine flow via a thermal energy exchange between the first brine flow and an airflow at a membrane contactor;
- flowing a second brine flow through a distiller a first time;
- heating the second brine flow at a condenser of the heat pumping unit after flowing the second brine flow through the distiller the first time;
- flowing the first brine flow and the second brine flow into the distiller, after heating the second brine flow at the condenser, the second brine flow flowing through the distiller a second time;
- extracting water from the second brine flow at the distiller via thermal interaction between the second brine flow flowing through the distiller for the first time and the second brine flow flowing through the distiller for the second time;
- and
- conveying the first brine flow and the second brine flow to a brine sump.
