Indoor Coil Specs. Finned length: 0.82 m Finned width: 0.44 m # Tubes / slab: 41 Single Pass / slab Fin depth: 16.5 mm Fin thickness: 0.10 mm Louver angle: 23° Fin height: 8.9 mm Louver height: 7.5 mm Louver pitch: 1.0 mm Louver entry length: 1.7 mm Louver redirection length: 1.7 mm # of louvers: 2 x 6 230 Figure A.7 R744 indoor single pass microchannel heat exchanger slab shown on the top with the arrow showing the direction of refrigerant flow. The bottom schematic shows three single slab evaporators as they are placed in the duct test section. A.2.3 RAC1 Outdoor Heat Exchanger In order to simulate the U-shaped heat exchanger of the R410A system, three flat microchannel heat exchangers are connected in parallel and placed together to form three sides of a box. The backside of this set of heat exchangers is covered with plywood. The same fan that was used with the R410A outdoor unit was also mounted to the top of this set of heat exchangers. The heat exchanger slabs for the outdoor coil are comprised of the same microchannel tube and header parts that made up the indoor heat exchanger slabs (see Figures A.5 and A.6). Each heat exchanger slab uses 80 total microchannel rows over 6 passes. More detailed specifications and a schematic of one of these slabs can be seen in Figure A.8. A comparison of the key parameters between the baseline and R744 system is shown in Table A.2. 55PDF Image | Comparison of R744 and R410A
