Energy Efficiency Management of an Integrated Serial Production Line and HVAC System

---

Modern manufacturing facilities waste many energy savings opportunities (ESO) due to the lack of integration between the facility and the production system. To explore the energy savings opportunities, this paper combines the two largest energy consumers in a manufacturing plant: the production line and the heating, ventilation, and air conditioning (HVAC) system. The concept of the energy opportunity window (OW) is utilized, which allows each machine to be turned off at set periods of time without any throughput loss. The recovery time of each machine is the minimum amount of time a machine must be operational between opportunity windows to guarantee zero production loss and it
is explored both analytically and numerically. The opportunity window for the production line is synced with the peak periods of energy demand for the HVAC system to create a heuristic rule to optimize the energy cost savings. This integrated system is modeled and tested using simulation studies.
Note to Practitioner—This work introduces the concept of an integrated production line and facility HVAC system to maximize energy savings in a manufacturing environment. Energy savings opportunities are developed along with the concept of recovery time for a serial production line. Simulation studies incorporate different ESO strategies for the production operations and changing set points for the HVAC system utilizing EnergyPlus software. These energy strategies use real time information such as buffer contents, machine speed, etc., to calculate the amount of time a machine can be turned off without throughput loss. This methodology is very useful for implementation in manufacturing facilities since it uses readily available plant floor data. This paper provides the framework for coordinating the two systems to maximize the energy cost without sacrificing throughput on the production line.
Index Terms—Energy savings opportunity, integrated heating, venting, and air-conditioning (HVAC) and production, recovery time.
