In summary, it is best to use a comprehensive analysis that reflects the actual weather data, building load characteristics, operational hours, economizer capabilities and energy drawn by auxiliaries such as pumps and cooling towers, when calculating the chiller and system efficiency. The intended use of the IPLV (NPLV) rating is to compare the performance of similar technologies, enabling a side-by-si de relative comparison, and to provide a second certifiable rating point that can be referenced by energy codes. A single metric, such as design efficiency or IPL V shall not be used to quantify energy savings.
With the flood of competing chiller types, manufacturers and performance claims coming to the market in recent years, the analysis of the chiller with the best payback has become both more important to the building owner and more difficult for the designer. Comprehensiv e building modeling tools such as EnergyPlus, TRACE™ or HAP that can compute hour-by-hour data provide the most accurate answer, but their processes can be quite daunting. And the time and information needed for such in-depth analysis may not be justified during the design process. Meanwhile, a simpler analysis method using generalized single point chiller- only metrics such as Integrated Part Load Value (IPLV) or full load performance completely disregard the specifics of the chiller( s) application. This simpler approach ignores critical application details such as building load profile, local weather and number of chillers in the system, among others.
It may provide the industry with a tool that bridges the gap between a full building simulation method and the overly simplistic and often misleading single metric me thodolo gies of IPL V, NPLV, or f ull load chiller design performance. The team determined that this tool must include the following criteria to provide accurate results:. chiller type and manufact urer agnostic.
annual building load profile. local weather. number of chillers in the system. chiller performance at appropriate operating points—both tons and temperatures. condenser water system control strategy. simple and transparent methodology. accurate ROI analysis based on electrical consumption and demand charges to guide users in.
Temperatures and time in each bin. The myPLV tool provides no advantage to any one chiller type or manufacturer. It simply provides a bin analys is for the load profile and chiller performance entered by the program user. Calculations use the specific chiller performance data provided by the individual manufacturers.
It assumes the user will request and the manufacturers will provide accurate and verifiable chiller performance data at each user-specified chiller load point and associated condenser water temperature. Figure 1 illustrates the flow of the myPLV analysis method. The goal of the myPLV tool is to evaluate. Establishing a load profile is often the most difficult part of an energy and economic analysis. Fortunately, ASHRAE and Pacific Northwest National Labs (PNNL) provide a solution. As a result of various ASHRAE standards efforts, PNNL has created a library of annualized load profiles (8,760 hours of data) for various building types in all weather zones of interest. The myPLV tool incorporates 200 of these load profiles within its database.
Each of the building types listed in Table 1 has been simulated within 20 climatic zones included in the myPLV database (Table 2) resulting in the 200 pre-defined data sets. Users simply select location information and building type and enter a. An airside economizer. Those profiles representing systems without an airside economizer will contain loads during cooler outside conditions. Load profiles incorporating an airside economizer will eliminate most low temperature loads since the economizer will satisfy the needed cooling.
For those chilled-water systems that incorporate waterside economizing (free cooling), users may wish to select load profiles with an airside economizer since the chillers will not be operating to satisfy loads during the cooler weather conditions. Having representative weather data is key to overcoming the IPLV problem of oversimplified analysis techniques which assume the same chiller operating conditions from Jeddah, Saudi Arabia to Fairbanks, Alaska and everywhere in between. The myPLV tool uses the 8,760 hour weather data set (TMY) contained within the PNNL load profile for a wide range of weather zones. Users may either enter a global location that maps to a st andard weather zone according to the dataset contained in ASHRAE Standard 169, or enter the weather zone explicitly by selecting. The number of chillers in the system and the capacity of the chillers are needed for myPLV to assess the operating conditions and time for the chiller-specific operating zones or bins. The program assumes all chillers are equal capacity.
Entering this information separate from the building peak load allows the program to account for oversizing of the plant capacity. Ultimate ninja setup.exe. The program outputs the plant oversizing factor per ASHRAE Standard 90.1, Appendix G for reference. An undersized plant is flagged in red with a negative oversize factor. In this case, the program will produce a solution; however, it will assume additional chillers are available beyond that specified with the input set. Cooling tower performance and control impact the operating conditions of the chiller for water-cooled plants. Users enter design tower performance data and selects a cooling tower control method.
Based on this information, myPLV calculates the entering condenser water temperature for each hour of the load profile. From the previous input information, the myPLV determines the weighted average operating conditions for the chillers in the plant for bins centered on the 25, 50, 75 and 94 percent chiller load points. The program also requires the chiller’s full load design performance to assess utility demand charges and to ensure an appropriate chiller is selected to satisfy the design requirements of the job. While the use of 25, 50, and 75 percent load points is similar to IPLV methodology, the ton-hour values and condenser water temperature weightings deviate from IPLV/NPLV to reflect the application.

You will likely be using water cooled centrifugals in this range as they will be very efficient, and have a good life. Two 300ton chillers will probably be a better base option, and serve the full building load without needing the lower efficiency pony chiller mentioned above. What you do from here entirely depends on the class of office building, low load and time spent at reduced load, which relates to climate and patterns of use:. VFD's are becoming very affordable and almost de rigour(outside of the tropics, where you may not have sufficient wet bulb suppression to make them worthwhile). Long periods of low load operation may necessitate a smaller pony chiller, and the size of this will come from your load trends for the whole cooling season, otherwise you might get away with the turndown/Hot Gas Bypass on your base chillers.
Some applications - occupant requirements or long cooling season for example - may make a third redundant 300ton chiller worthwhile. RE: Chiller Selection (Mechanical) 30 Mar 10 13:53. Not such an easy question to throw out there.
HVAC68 is hitting the point when he(she) refers to load profile. I have found that spot cooling in a number of critical areas are more common and not so easily answered by a low load chiller. Areas like fire alarm system panels have batteries that tend to overheat if not properly cooled, pharmacies, conference rooms, telecom closets with router switches.you get the picture. All with different needs, different areas, ect. You really need to look at the load profile in the big picture. RE: Chiller Selection (Mechanical) 19 Apr 10 08:36.
