Qusetion, if a OEM motor is size at 208/230v 1050 rpm. Could you replace it with the same voltage but a 1075 rpm motor. How much is the different between cfm with a 1050 verses a 1075 rpm? Thanks
We are having and issue with air in our steam absorber. We had a ex-McQuay tech. in to decrystallize the chiller for 6 hrs. he add deionized water to the heat exchanger to do this. After about 30 hrs of work it is running but we still are getting air bubbles out of the purge tank and vessel...
How would you calculate for % of outside air into a 87,000 sq/ft library using 4 AHU's delivering a total of 115,000 cfm into the building. We currently are using 35% OS air at the dampers. What would the air exchanges be p/hr? Thank You
