Finally, I will finish this post with a few considerations, and tips. Less perhaps in the case of corridors or gowning areas. The most used insulation cores in standard cleanrooms are Rockwool and Polyurethane (PIR or PUR). Designers should consider performing cooling load calculations for rooms and zones with all of the internal gains fully on (e.g. Friedman notes that engineers face several challenges when it comes to determining heat gain of equipment. ASHRAE has released a new standard that provides a test method to determine the heat gain generated by office equipment. # A b `k NtDK0`}.
