Researched availability of mobile air conditioners for renting -> possible at 90 kr/day pr. 2 kW

A meeting was held Tuesday to determine the course of the experiments. The meeting concluded that

• If possible, the experiments should be performed this side of Christmas. If not, the PV group must wait.
• Using the highest possible ventilation rate of 30 l/s/pers = 180 l/s should be sufficient for cooling. No serious noise problems expected. Odour sources can be added, if desired.
• Cooling equipment should not be added for various reasons
• Using only 4 subjects at a time through a 3-week period would be acceptable
• Reducing the number of conditions to 2 would be a shame, and thus is not an option
• The exact conditions were only mentioned sporadically; there seemed to be an understanding on the scheme that could evaluate the effects of low air temperature and low ventilation rate which, as mentioned, might as well be achieved by using a high ventilation rate and a pollution source.
• It was decided to have another meeting late on the day of Thursday, November 9. At this time further heat balance calculations should be available. Further experiments should also be made in the field lab, to determine the air temperature at 3 and 6 air changes per hour (corresponding to 15 and 30 l/s/person).
• It will then be decided whether subjects should be recruited in order to perform the experiments before Christmas as planned, or whether a new strategy should be adopted.

Work during the rest of the week focused on revealing the exact cooling power, as well as the exact heat load that was to be expected.

It was discovered that the cooling system already installed had an outdoor temperature range of 20° C to 40° C, and thus there was a risk of system failure. We discussed the problem with the experts on first floor, and came to some possible solutions.
