Read full description

This is a suite of twelve apps published already are put together to facilitate as a tool for performing energy efficiency studies especially in energy intensive chemical and process industries as well as HVAC applications. Hence, this can serve as an onsite analysis tool for energy engineers, auditors and technical personnel for assessing the energy saving potential. Further it can save more than 50% in total cost of individual apps. Apps can be grouped under three different categories such as supporting apps, device apps and energy cycle apps as given below. Supporting Apps: 1. Thermo-Physical Properties (16 common industrial fluids) 2. Fluid ΔP (Fluid pressure drops in pipes and conduits) 3. Orifice flow (Measurement of flow rates in pipes) 4. Engineering unit conversion (SI to USCS unit conversion) Device Apps: 1. Boiler Fuel Efficiency (with CHP) 2. Centrifugal Pump Specification 3. Fan Specification Performance 4. Compressor Capacity Performance 5. Heat Exchanger Performance Energy Cycles 1. Rankine Cycle 2. HVAC Cooling Cycle 3. HVAC Heating Cycle Users can save all their application data pertaining to energy cycles as well as major devices (Boiler, pump, heat exchanger and fan-duct system) in a file with unique title for reviewing and monitoring individual performance time to time. Users can use either SI and USCS units for both inputs and output. Please note that CHP (Brayton) cycle is part of BoilerFE app. The screen shots shown are mainly for energy cycle (Rankine and HVAC cooling cycles) apps. Therefore, please refer App stores for all other individual app descriptions and screen shots that were already published. Additional details are also available at our web site www.flowjoule.com/download.html This application suite has all the current updates with bug fixes for devices with iOS 14.. and higher and this will be frequently updated with added features time to time.
