CompCap (Compressor Capacity) App is developed mainly to estimate different key performance indices in single stage Industrial Air compressors. Users can generate as many application data of their compressors and save it in a file for future monitoring and review. Further, It also assists in running quick tests to estimate FAD and leakage in the compressed air systems in order to assess the potential energy savings. App can work with both SI as well as USCS units for input and output as shown in the example screen shots.

Manufacturers give compressor specification data such as FAD, power and other efficiencies at certain standard operating conditions. But, most compressors normally operate between two set pressure points for loading and unloading. Therefore app uses a hypothetical pressure ratio of average discharge pressure to ambient to compute different performance indices. Further, any change in operating conditions such as atmospheric pressure due to altitude, temperature, humidity etc. could also have considerable impact on compressor performance as shown in screen shots. Thus app can be helpful tool to different operation and maintenance personnel to evaluate compressor performance time to time.

Ambient Properties:


Compressor Specification Data:
A typical compressor specification data sheet is show in the screen shot. FAD, pressure rating and motor hp and rpm data are the minimum requirement based on manufacturers data sheet. Additional data pertaining to reciprocating cylinder data helps to determine the range for FAD for general verification. Volumetric efficiency is primarily depended upon cylinder clearance and generally present in most compressors and in the range of 2% to 12% of total swept volume.

FAD/Leakage Testing
As the compressor put more hours on service, the natural wear and tear could bring down the performance of any compressor. Therefore, it is often necessary to run tests to determine its capacity and also any excess leakage in the compressed air system. This app helps to run quick tests to estimate the losses and concern for any further investigation.

Result Summary:
A comprehensive result summary provided that includes heat load for the inter coolers, moisture content etc. as shown in screen shot. Additional information is provided in app notes that include FAD, leakage computation models for quick reference. Also in this version provided link to documentation on implementation and validation of math-models along with maintenance requirements as well.
