"The purpose of this study demonstrate the effects of three air distribution layouts on the uniformity of temperature and humidity within the Agaricus bisporus mushroom production rooms at the Mushroom Test Demonstration Facility at the Pennsylvania State University. The study involved monitoring carbon dioxide levels and the three different air distribution schemes that provided a mixture of fresh and re-circulated air at an exchange rate of 6 to 9 air changes per hour. The concern was that the bottom production trays tended to experience the coolest, driest air conditions in the room, and the air over the middle production trays was generally warmer with higher moisture levels. However, data analysis determined that improved uniformity of mushroom production did not correlate with an improvement in quality or increase in yield."
