The AC guys are here to fix the compressor trouble. Now planning to keep two of them on the first-floor parapet and only one downstairs. Temperature readings with a room thermometer kept horizontally: before we started the test, room temperature indoors was 32 deg C. After putting on one of the compressors (and the blowers) the temp near the window was 41 deg C. The theatre was being barely cooled down to 30 deg C. But at least the compressor did not trip. When we opened the windows, the temp near the window quickly dropped to 33 deg C, indicating that indeed there is an air circulation problem. Hope the two feet clearance between units upstairs will be enough! PR has some ideas of baffle walls to prevent hot air being sucked into the rear inlets, too. Hopefully with all that and all three compressors running, we can get the theatre cooled.
One more issue is with the electrical connections. The starters used and the cables used are all getting heated up with the 22 amps per phase being drawn. And that's just for one compressor! If this is normal, then these compressors are less efficient than our old ones, which used to take around 35 amps each - and we used to run only one of them at a time.
