This results in a higher quality part and reducedĬycle time, allowing manufactured parts to be produced faster. Desiccant dehumidifiers canĮliminate this condensation. As the air or process is cooled below theĪmbient dew point, condensation can occur. Industrial and manufacturing companies use chilled water to remove heat from Psychrometrics, it’s possible to determine the proper humidity ratio of the The ceiling since the temperature often goes below the dew point ofĪmbient conditions (it’s called “raining in the OR”). Hospital ORs are kept so cold that there is always risk of condensation These HVAC systems must be operational 24/7 and often This system is designed toĬontrol the environment for the preservation of highly valuable artifacts or Pollutants) within a museum, a library, or any type of archival facility is much more complex than the systemĭesigned simply for maintaining human comfort. Systems designed for controlling the environment (temperature, humidity and The following slide displays the comfort zone for humans: It’s vital for human comfort since it’s difficult to work when the conditions are too Study and understanding of psychrometrics is so important for helping engineers toĭesign HVAC systems for all types of applications and situations including: Show 10 example HVAC processes using the psych chart app. I will split this topic into 2 separate blog postings. This webinarĬould have easily gone on for two hours, but I was limited to one. Then, Iĭemo’d the app by creating sample HVAC processes.
This webinar included an overview of the science behind psychrometrics.

Is keen interest in understanding psychrometrics and also finding ways I was amazed thatĪlmost 900 people registered for this webinar. Psychrometric Chart iPad app (which we designed). Display psych process line as curved along 100% RH line.I recently hosted an ASHRAE-sponsored webinar that discussed theīasics of psychrometrics and also included a demo of the ASHRAE Zoom in or out of the chart by "pinching" the iPad screen so as to view items in more detail.8. Also, you can create templates that you can reuse over and over again.7. Create an unlimited number of psychrometric chart projects.
After you have completed creating the chart, you can email a list of all the points and their properties along with a PDF of the chart, itself.6. Also, create custom labels anywhere on the chart.5. Create psychrometric processes by plotting points then connecting them with process lines. In addition, you can double-tap a point to display the point properties and then edit them.4. As you move your finger around the graph, the psychrometric properties at the top of the screen dynamically update. Using your finger, you can plot as many points as you want on the screen. Allows you to customize the graph in many different ways including specifying the psychrometric chart line colors, chart background color, hide/display status of chart lines, point colors, process line colors, units of graph values, and the min/max limits of the chart.3. Displays a fully customizable psychrometric chart in both landscape and portrait modes.2. The HVAC Psych Chart app includes the following features and functionality:1. It is now optimized for iOS 9.Using your finger, you can easily plot HVAC and other psychrometric processes on the iPad screen while you are out in the field, save the graphs, and then email the graph and results to yourself or clients. The HVAC Psychrometric Chart app is the first truly interactive graphical psychrometric chart for the iPad, and it includes both IP and SI units.
