SUMMARY
The discussion centers on the significant increase in cooling load when utilizing 100% outside air in ventilation systems for laboratory environments. Participants noted that the cooling load can exceed 4 refrigeration tons (RT) compared to standard conditions due to the high volumes of unconditioned air. The system under consideration is a Constant Air Volume (CAV) system with terminal reheat, which may not be the optimal choice for such scenarios. Utilizing a psychrometric chart is recommended for accurate calculations of cooling loads in these conditions.
