This month's B2B focuses on a new cooling tower to serve a pharmaceutical facility's new process water system. This tower will be a closed-loop, evaporative condenser to operate 24/7/365. The tower will have a floor-mounted end suction condenser water pump, and a second pump will serve as a standby. Each pump shall have a VFD to respond to the variation in flow to the 20-process equipment heat exchangers each with two-way modulating automatic temperature control (ATC) valves. The tower shall also have two variable-speed, forced-draft fans to provide additional fan capacity in the event that one fan fails.
The design team includes the HVAC, structural, plumbing, and electrical consultants, and the HVAC consulting engineer will serve as the prime engineer for this HVAC infrastructure addition. The pharma capital project manager will retain a third-party commissioning and testing, adjusting, and balancing (CxTAB) consultant.
The pharma facility operation and maintenance (O&M) manager should review the design HVAC engineer's proposed scope of work based on the 2016 ASHRAE Handbook - HVAC Systems and Equipment, Chapter 1, HVAC System Analysis and Selection, to determine the optimum cooling tower application for this pharma equipment line.
The O&M staff also will be provided access to 2016 ASHRAE Handbook, Chapter 14, Condenser Water Systems, and Chapter 41, Evaporative Air-Cooling Equipment. The O&M facility manager and design team should also review 2019 ASHRAE Handbook - HVAC Applications,...
