here at par Tech at Queen's University
00:00:08.059 00:00:08.069 we're working on a unique solution to a
00:00:10.610 00:00:10.620 problem that affects heating systems
00:00:12.259 00:00:12.269 we're all familiar with the
00:00:13.549 00:00:13.559 calcification that happens on a
00:00:15.049 00:00:15.059 showerhead or the bottom of an electric
00:00:16.849 00:00:16.859 kettle this problem can be particularly
00:00:18.980 00:00:18.990 acute in parts of the heating system
00:00:20.840 00:00:20.850 called the heat exchanger this device
00:00:23.029 00:00:23.039 uses narrow channels for two liquids to
00:00:26.509 00:00:26.519 transfer heat between one another
00:00:27.830 00:00:27.840 without mixing the problem occurs
00:00:30.200 00:00:30.210 because the heat releases the mineral
00:00:32.569 00:00:32.579 content just like in your kettle and
00:00:34.340 00:00:34.350 congest the narrow passageways in a heat
00:00:36.650 00:00:36.660 exchanger we've developed a system that
00:00:39.440 00:00:39.450 allows it to be flushed of all of the
00:00:42.910 00:00:42.920 impurities and dissolved minerals which
00:00:46.610 00:00:46.620 may form in the heat exchanger and we've
00:00:49.910 00:00:49.920 applied a very simple technology we just
00:00:52.100 00:00:52.110 reverse the flow of the fluid through
00:00:55.250 00:00:55.260 the heat exchanger but what makes this
00:00:57.799 00:00:57.809 unique is that we do this passively so
00:01:01.910 00:01:01.920 every time a homeowner or a user
00:01:05.469 00:01:05.479 consumes water then the heat exchanger
00:01:09.500 00:01:09.510 itself is is passively flushed of any
00:01:13.840 00:01:13.850 particulate matter or anything that
00:01:15.950 00:01:15.960 could cause fouling in the heat
00:01:17.090 00:01:17.100 exchanger our technology allows for the
00:01:19.609 00:01:19.619 world's most effective heat exchangers
00:01:21.380 00:01:21.390 to be used globally which will lower
00:01:23.240 00:01:23.250 maintenance and replacement costs and
00:01:25.429 00:01:25.439 make the best use of the energy
00:01:27.350 00:01:27.360 available
