^ | 15:58 | SC | m= 27.64, loop3 open, system in run mode |
^ | 16:20 | SC | m=25, Loop3 open, system in recovering |
^ | 17:07 | GG | m=22.5kg. No liquid in compressor. Recovering. Discovered serious detachment of the HSs on sector 1. Failure analysis on going. |
Tue 09/May/06 | 09:51 | GG | m=30.0. |
^ | 17:27 | GG | System found in ALARM for weight variation. m=31.5. Reset. RECOVERING. |
Wed 10/May/06 | 11:38 | GG | m=32.5kg. Loope 3 open, all the other locked. |
^ | 11:46 | GG | Temperature on the sector boxes and on the HSs is 21C (measured with </nop>quickTEMP, infrared thermometer). RUN. |
^ | 12:05 | GG | Temperature on the HSs is 17C. |
^ | 12:24 | GG | When powered, the normal HS reach 25C, the detached even more than 30C. |
^ | 13:22 | GG | m=24.0kg. RECOVERING. |
^ | 19:27 | GG | Other tests performed during the afternoon. SC reported that the system was in ALARM. Now is RECOVERING with all loops opened. |
Thu 11/May/06 | 09:33 | GG | m=29.6kg. Locked all loops (at 0.4b) but 2 and 3. |
^ | 11:42 | SC | m=29.58 kg. Locked Loop2. system in Runmode |
^ | 13:17 | SC | m=22.5 kg. Loop 3 open, sysrem in recovering |
^ | 17:50 | GG | m=29.6kg. RUN |
^ | 17:59 | GG | m=27.2kg. Knee in the weight drops after 4 min. Stable temperature reached after 9 min. Return pressure rise up to 1.7b and decrease, with the compressor , again at 1.4b. When stable is at 1.55b. Temeprature test with IR camera and PT1000 measurements. |
^ | 18:48 | GG | m=24.0kg. RECOVERING. |
Fri 12/May/06 | 10:54 | GG | m=29.6kg. Created a plots folder in D:\PVSS_Projects\SpdCooling_20060220\Plots . In steady state there is a stdev of 0.010kg. Limiting the data precision to 0.01? |
^ | 11:27 | GG | At 11:08 a slow increase of the weigth starts. Now is at 29.9kg. The compressor is still full throttling, the chiller is at 7.5°C, the loops are locked but loop 3. Pressure in the loops is 0.38b but loop 1 at 0.45b. |
