Credits Overview The aim of this web app is to create an interactive psychrometric chart on which you can project a range of comfort metrics as well as mapping weather data or room air conditions calculated using EnergyPlus. You can add or remove lines for a range of different metrics or highlight them individually to assist with dynamic explanations or presentations. The Psychrometric Chart The terms psychrometry and psychrometrics refer to the study of moist air and its thermodynamic properties. Whilst obviously important in the design of air-conditioning systems, these concepts are also fundamental to the understanding of many aspects of thermal comfort in buildings and the principles of climate-responsive design. The Relative Humidity Chart When developing this tool, I really wanted to be able to morph seamlessly between the standard psychrometic chart and the much simpler relative humidity chart. Having taught psychrometrics to architects in the past, I found that a major hurdle was trying to convincingly explain why the psychrometric chart uses absolute humidity in the vertical axis instead of the more familiar metric of relative humidity, and why its characteristic curved layout is so important. Now, by simply animating back and forth between the two chart types, most of that explanation becomes pretty obvious as you get to see very clearly the majority of psychrometric processes change from straight lines under the absolute humidity axis to complex curvilinear lines under relative humidity.

The versatility of the psychrometric chart lies in the fact that by knowing three independent properties of moist air one of which is the pressure , the other properties can be determined.

Changes in state, such as when two air streams mix, can be modeled easily and somewhat graphically using the correct psychrometric chart for the location's air pressure or elevation relative to sea level. For locations at or below m, a common assumption is to use the sea level psychrometric chart. The thermometer's bulb is dry.

It is typically the x-axis, or the horizontal axis, of the graph. The Metric Units are Celsius. Dry-Bulb temperatures are graduated from left to right along the sole.

It is typically the y-axis, the vertical axis, of the graph.

Humidity ratio is dimensionless, but is sometimes expressed as grams of water per kilogram of dry air. Specific humidity is closely related to humidity ratio but always lower in value as it expresses the proportion of the mass of water vapor per unit mass of the dry air and the water vapor. Humidity values are graduated, bottom to top, along the heel. This chart has grams of water per kilogram of dry air. The heel also shows vapor pressure.

Vapor Pressure is the pressure exerted by the water vapor in air, and it varies with temperature since the water "holding" capacity of air changes with temperature.

It is given in millimetres of mercury. Humidity readings are plotted horizontally.

These values represent Dew Point and Wet-Bulb. This is also known as the saturation line.

Interesting Features The following are some of the features of this app: You can position the current indicator by pressing and dragging anywhere within the chart to see the relevant psychrometric values at that position, all listed in the top-left corner of the psychrometric chart. When overlaying the Givoni Bioclimatic Chart, you can adjust the average mean outdoor air temperature used to derive the comfort zone in order to investigate the effects of adaption.

You can also choose to automatically track average mean outdoor air temperature based on loaded hourly weather data and the current date range.

In addition to annual hourly weather data, you can also load and display the results of EnergyPlus calculations. Either select the Load CSV CSV file into the browser window containing this application.
