AI Technical Summary

Problems solved by technology

This packed bed system has other disadvantages besides the still diversion risk: the high airflow resistance of the packed bed results in higher fan power and higher pressure drop across the packed bed, thus requiring more energy
Metals that do not corrode easily, such as titanium, are often viewed as expensive to use and difficult to machine
Plastics can be used, but they typically cannot withstand the operating pressures and temperatures typically used for fluids

Embodiment Construction

[0105] Figure 1 illustrates a prior art three-way heat exchanger in which air enters a stack of vertical plates. These vertical plates are supplied with cooling fluid 38 and covered with flocking material. A liquid desiccant is applied to the flocking material which slowly descends along the surface of the panel while absorbing water vapor from the air stream and conducting heat from condensation and air into the cooling fluid.

[0106] FIG. 2 shows a cross-section of the prior art plate of FIG. 1 , where cooling fluid enters at location 34 , flows down to bottom location 38 and returns up to upper location 38 . The fluid then flows again to the bottom and back up to the outlet port 36 . The long, narrow channels in the fluid flow result in laminar fluid flow and, as can be seen in the figure, the incoming air flow at 10 is at right angles to the cooling fluid flow.

[0107] Figure 3 illustrates a bi-directional heat exchanger where an alternating pattern is applied to a ser...

Abstract

The present invention relates to a heat exchanger for use in a desiccant air conditioning system comprising: a plurality of diaphragm assemblies facing each other in a substantially parallel configuration and spaced apart so as to define therebetween an air gap through which the air to be processed by the dehumidifying air conditioning system can flow, each of the membrane plate assemblies includes a plate structure, two membranes, at least one desiccant discharge port, each membrane is opposite sides of and spaced from the plate structure so as to define a gap therebetween through which liquid desiccant can flow, wherein each membrane has a bottom portion sealed to the plate structure , such that the liquid desiccant is forced to flow through the at least one discharge port, thereby creating a negative pressure in the gap between each membrane and the plate structure. The heat exchanger of the present invention is corrosion resistant and cost effective.
