Alan R. Neuner, Vice President Facilities Operations Geisinger, 100 North Academy Ave., Danville, PA 17822

570-271-5515 Fax: 570-214-2570 aneuner@geisinger.edu

Alan R. Neuner, a native of Nazareth, Pennsylvania, received his mechanical engineering degree from Drexel University and worked for several years in the steel and air separation industries. In 1988 he joined the Facilities Operations staff of the Geisinger Health System, an integrated health system with facilities dispersed across a 31-county service area in central and northeastern Pennsylvania. As Vice President for Facilities Operations, Al is responsible for over 300 employees servicing a physical plant of over 10 million square feet. The main campus in Danville realized a significant energy savings because Al and his staff devised a creative strategy to manage energy resources, which resulted in a 40% reduction in overall energy consumption per square foot, including chilled water storage, cogeneration, and LEED commitment. Most recently, the site scored a perfect 100 on EPA’s Energy Star. Al has won many awards for his achievements. He received the prestigious 2002 Fame Award of Excellence from the Association of Facilities Engineers for his work on legionella remediation, the Chesapeake Bay Foundation awarded him the 2000 Businesses for the Bay Award for large business for pollution prevention and energy reduction, and the 2012 Donald M. Sauerman Award for Outstanding Contributions to the Field of Health Facility Engineering.

Bud Fogleman, Sr. Market Outreach Specialist, PPL Business Rebate Program 3 Park Plaza Suite 101, Wyomissing, PA 19610

814-660-2185 Bud.fogleman@cleareasult.com.

Bud has been involved with delivering Energy Efficiency Programs since 2013. He works closely with contractors and customers to navigate the rebate program and assists them with the identification of efficient improvements that can be made at their facilities and the application of the rebate programs for their projects. Prior to joining the Energy Efficiency industry he has spent time in construction, project management, maintenance and inspection; providing a wide perspective to the projects he works on. He has worked to establish specialty channels in the PPL program in Phase 3; the introduction of Advanced Lighting Controls where he has helped to prove the greater benefit of these systems, which has allowed the payment of a higher incentive rate than that of standard lighting systems. Additionally in Compressed Air where he has helped to incorporate additional control measures to prescriptive small horsepower system rebates, champion it’s inclusion into the Direct Discount Program and lead the development and implementation of a leak repair program. And most recently introduced and help to organize a Compressed Air Challenge Course.

25Alan R. Neuner

What is a chiller?

A chiller is a device that uses refrigerant to transfer heat from a lower temperature source to a higher temperature source using refrigerant as the exchange media

The refrigerants lower boiling point utilizes phase change (gas to liquid) to accomplish this task

26Alan R. Neuner

Refrigeration Cycle

27

Flows and temperatures Generally, chillers are

designed for 2 GPM of evaporator flow (chilled water) and 3 GPM of condenser flow

Chilled water leaving temperatures are 42 degrees and entering temperatures are 54 degrees (12 degree T)

Operating Efficiency

Regardless of what energy source is selected, efficiency should be determined for site specific operating conditions (partial load conditions as well as condensing temperature variations)

Generally IPLV is a better measure for actual operating conditions for chiller applications than NPLV

Alan R. Neuner 31

Thermal Lift

The amount of energy to create cooling is proportional to the differential temperature.

Example: creating 42°chilled water with 85 °condensing water uses more energy than using 75 ° condensing water.

Condenser Options

Air cooled – approach based on ambient temperatureNo pumping horsepower required

Water cooled – approach based on wet bulb temperatureWet bulb normally significantly lower than dry

equals 2% of compressor horsepower

34Alan R. Neuner

Condenser Water Temperature

Lower normally betterMost cooling towers set for 85°FMost towers designed for 10° approach to wet

bulb Lowering set point to 60° will reduce chiller

horsepower 30% when obtainable Installing 5° approach towers will lower chiller

power consumption 10 to 15% or increase capacity accordingly

35Alan R. Neuner

Cooling Tower Control

Tower designed for specific approach to wet bulb (5°)

If tower set point is 60°, many days the tower is incapable of achieving this, wasting fan horsepower

By installing wet bulb control, fan horsepower is reduced by 50%

Variable flow towers allow multiple chiller/tower combinations to promote peak chiller efficiency and minimize fan horsepower

Off Peak Storage

At night, condensing temperatures are lower Cooling loads are also generally decreasedBy providing storage capacity (i.e. chilled water

storage tank), chillers can be loaded at night, cooling the tank, for use the following day

Reduces the required installed tonnage and peak electrical demand

42Alan R. Neuner

Discharge Reset

If ambient outdoor temperatures or humidity's are low, chilled water discharge temperatures can be increased

As with condenser water changes, increasing chilled water temperature by 1° decreases power consumed by 3%

Alan R. Neuner 43

Waterside Economizer

If there is a cooling load in colder outdoor temperatures, a plate frame heat exchanger can utilize condenser water to cool chilled water

Our experience results in savings of about 1500 chiller hours per year

All other auxiliaries required (cooling tower fans, condenser pumps, & chilled water pumps)

44Alan R. Neuner

Variable Chilled Water Flow

Under partial load conditions, full chilled water flow is not required

Pumping horsepower can be conserved by reducing flow to maintain a constant T across the evaporator or P at a point in the system

Requires replacement of 3 way valves with 2 way for optimum efficiency
