New App and Updated Calculators Help with Design and Evaluation of Mechanical Insulation Systems
The National Insulation Association is proud to announce its first-ever mechanical insulation smartphone application: the Mechanical Insulation Financial Calculator. Based on the Financial Returns/Considerations Simple Calculator in the Mechanical Insulation Design Guide (MIDG), this app helps quickly determine the financial returns related to investments in mechanical insulation. It can be used for an overall project or a small investment such as insulating a valve or replacing a section of insulation.
The app is available for Android phone users in the Android Marketjust search for "mechanical insulation." Use this free tool to find out how quickly mechanical insulation can pay for itself in a building or facility and discover how much energy, money, and greenhouse gas emissions can saved and what the return on investment will be.
In addition, some of the other MIDG Simple Calculators have been updated, with a new Personnel Protection Calculator added and the Temperature Drop Calculator split into two based on application type:
- Temperature Drop Calculator for Hydronic Piping: This calculator estimates the temperature change of water flowing in a pipe. An example is the use of insulation to minimize temperature (drop or rise) of a process fluid from one location to another (e.g., a hot fluid flowing down a pipe). Based on input, this calculator will provide temperature drop (or rise) in °F and leaving water temperature in °F.
- Temperature Drop Calculator for Air in Ducts: This calculator estimates the temperature drop (or rise) of air flowing in a duct. An example is the use of insulation to minimize temperature change of a supply duct in a commercial building. Based on input, calculator will provide temperature drop (or rise) in °F and leaving air temperature in °F.
- Personnel Protection Calculator for Horizontal Piping: In many applications, insulation is provided to protect personnel from burns. In addition, there are safety and comfort concerns related to personnel working in high temperature, high radiant exposure locations. This new calculator helps prevent severe burns by estimating the time personnel can be in contact with surfaces above 140°F (the standard industry practice) without suffering second and third degree burns. For example, surfaces at the standard temperature of 140°F contacted for up to 5 seconds would cause no more than first degree burns. Based on input, calculator will provide surface temperature in °F and maximum contact time in seconds.
These calculators are useful for both the beginner and experienced professionals in the construction, design, specification, maintenance, management, and budgeting fields. The Mechanical Insulation Design Guide, located at www.wbdg.org/midg, is used by design professionals, corporate management, facility owners and managers, energy and environmental consultants, mechanical engineering teachers, and mechanical insulation industry manufacturers, distributors, and contractors, among others.
The calculators were developed for MIDG by the Mechanical Insulation Education and Awareness Campaign (MIC), part of efforts by the Department of Energy's (DOE) Industrial Technologies Program's Save Energy Now initiative to improve the energy efficiency of the U.S. industrial and commercial sectors. Project Performance Corporation and the National Insulation Association, in conjunction with its alliance with the International Association of Heat and Frost Insulators and Allied Workers, are working together to execute the MIC.
