I found that the axiflow fans were just good at circulating hot air - I absolutely hated them compared to the ceiling fans of the Arnines.When it's hot and humid, nothing seems to help. I do remember the thermostatically controlled plenum's in the ceilings of the R-32 when riding. When the R-32's were new and the weather was just warm, you'd hear the sounds of the motors opening or closing the plenum's one section at a time all down the line. I guess as years passed and with deferred maintenance, the plenum's probably weren't maintained and just broke down. The debut of the picture windows that barely opened made things much worse. The design of the European styled vent windows starting with the R-33/36's were probably an answer to public complaints of open drop sash windows that would let in rain during a downpour. The flip in vent window would almost eliminate folks getting rained on while sitting on the seats. But you're right, the drop sash windows were best for ventilation, considering it wasn't raining outside. Bill Newkirk |
